CL make a range of cam locks, desk draw locks, filing cabinet locks and many other utility locks which are available from locksmiths in Brisbane. The CL range of locks represents a broad number of the most common utility locks for use in Australian homes and businesses. If you need a lock for a letterbox, desk drawer or shop display cabinet the CL locks can more then often provide the right lock for the job.

CL Lock barrel being inserted into housing Brisbane locksmithCL locks are designed for and sold by your locksmith. As a specialty locksmith product they come in a disassembled form. The lock bodies come separate from the cylinders. With the cylinders sold separately it is easy to change the cylinders to suit our customers needs. If a customer wants multiple locks on the same key, the cylinders can all be keyed alike and then inserted into the lock housing. If groups of keyed alike locks are needed, the cylinders can be adjusted or keyed into groups then inserted into the lock housings.

CL Lock desk drawer lock Brisbane locksmithAs the lock cylinders are sold separately to the the lock housings, CL has introduced a range of higher security dimple key cylinders. The dimple key cylinder mechanism works a little different to regular flat keys. The dimple key has holes or dimples drilled into the flat sides of the keys. The different depths and spacing of the dimple corresponds to the combination of the lock.

CL Lock filing cabinet lock locksmith BrisbaneThe dimple key cylinders make lock picking a lot more difficult. There is a lot less room in the lock cylinder to insert and manipulate the lock tumblers. This higher difficulty in lock picking gives the dimple lock cylinder an edge over the standard wafer lock. For many situations such as letter box locks where the standard locks can be easily picked or even a master key used, a dimple key letterbox lock offers a much greater degree of security.

CL Lock Keys Brisbane locksmithThe dimple key lock cylinders have a unique design where a notch in each disc pushes into the dimple of the key. The lock cylinder contains 6 spring loaded discs which must all precisely line up when the key is inserted to allow the lock to turn. Each disc can have 4 different depths which correspond to 4 different dimple sizes in the key. Only the correct key with the right combination of dimples will allow the lock to open.

The dimple keys are much shorter then a regular house key. They are made from nickel plated brass and have a stylish black plastic head. The keys are stamped with a code number that is used when keyed alike locks are required. The keys could be cut to code although at this time we are unable to make an original key from the code number stamped on the key.

The CL range of cam locks and drawer locks is very well priced and the dimple key range of cylinders is the cheapest non standard higher security utility locks we sell. By far the largest demand for these cheap dimple locks is for letter boxes. The dimple lock range of CL cam locks would make any criminal stealing mail think twice.

Abus Deadbolt Double Cylinder

Abus Deadbolt Double Cylinder

Abus is a very well known brand worldwide. It is known for its padlocks, bike locks and security related products. So how does the Abus double cylinder deadbolt hold up for security and quality?

Well you would expect the Abus double cylinder deadlock to be made in Germany. This lock however is made in Taiwan. The packaging and look of the lock do not look to be very different from many other Taiwanese made deadlocks on the market.

locksmith Brisbane deadbolt AbusThe finish on the Abus deadlock is very good. It has a bright chrome finish with an embossed Abus logo on the outside cylinder. Even the locking bolt has a bright chrome finish.

The locking bolt is adjustable to 60mm or 70mm. Adjusting is simpley done by twisting the front and back parts of the bolt assembly when the bolt is in the thrown position. The actual locking bolt also is made from solid steel with an insert in the centre to resist sawing attacks. The steel bolt is a bit of a surprise as most other similar deadbolts use a brass locking bolt.

The solid bolt is longer then the thrown portion of the bolt, leaving 10mm inside the bolt assembly. This gives the bolt extra strength from prying attacks then most other deadlocks of this type.

The lock body has two cylinders with pressed metal housing and a spacer ring behind each housing. The spacer ring can be removed for thick door types making the lock suitable for locks between 35mm – 45mm.

The lock cylinder of the Abus deadbolt mounts into a metal housing and is removable. It can be replaced with a high security cylinder. The lock cylinder can also be replaced with a registered key barrel if required.

The lock cylinder and barrel are a 6 pin design although out of the box a 5 pin key is used. The code on the key matches the cuts of the key.

The Abus deadbolt has no resistance to lock bumping or lock picking. The pins used in the lock are standard and no security pins are used.

Adding a registered security barrel or replacing the barrel altogether can make this lock a lot more secure. High security lock pins can also be added to increase security and stop lock bumping attacks or lock picking.

The lock has no hardened inserts to stop drilling attacks. Hardened pins in the lock barrel assembly and behind the mounting screws would have made this lock much harder to drill off the door.

Fitting the lock to a wooden door is fairly straight forward. It has the same standard tubular deadlock holes for fitting as most other deadbolts. This makes it easy to replace an existing deadbolt.

The Abus double cylinder deadbolt is a well made lock. It has a very smooth operation and should last for many years once fitted.

Abus give it a security rating of 7, which seems quite high for a lock with no pick protection, no bump key protection and no drilling defence. While high security barrels will increase the security of the lock when fitted to a door, out of the packet the lock is not a high security lock.

Lockwood security deadlock

Lockwood security deadlock

Feature packed Lockwood deadlock for Brisbane

Deadlock for commercial and domestic use by Lockwood. Safety indicator. Secure silver deadlockThe 005 Deadlock from Lockwood is a stylish deadbolt with some features that have been lacking from other deadlocks. A deadbolt is a deadbolt right? Well, not really! While they might all look similar, there are some big differences between the Lockwood 005 deadlock and others.

The first thing you will notice about the Lockwood 005 is…. well it looks very different from other deadlocks! Thin round profile on the outside. Looks more like a Lockwood 001 deadlatch on the inside. 4 screws to hold the bolt in the door. 4 screws for the strike. The bolt is shorter then many other deadbolts. This is a deadlock that is totally redesigned!

Door fixing

005 deadlock fixed to door with 4 screws in bolt. secure against burglary and lock picking. OK lets start with the 4 screws. I don’t think I have seen a lock made for the Australian market with a 4 screw strike or bolt before. Does it make much difference? Well yes it does! If you have ever seen a door kicked in, you would know they always split up the middle of the door. So why put screws right in the centre of the lock? It makes sense to offset the screws. It makes for less of a centre break line and four screws are better then two.

This lock is also able to be fitted in the place of an existing deadlock or even an entrance lock. Quite often when fitting over the holes of an existing lock, the screw holes for the bolt and strike have been cross threaded or over-tightened leaving the holes unsuitable for new screws. For the Lockwood 005 deadbolt the screws thread in each time as they are not dependent on existing screw holes.

Inside locking knob

Inside locking knob Lockwood 005 deadlock fitted Locksmith BrisbaneThe inside of the Paradigm deadlock looks very similar to the inside knob of the Lockwood 001 deadlatch. In fact it works in much the same way, no surprise. It has a little window on the face of the knob that indicates whether the inside knob is in a deadlocked or undeadlocked mode. When the indicator is red, the inside knob is locked and can not be turned. This either indicated that the deadlock is deadlocked closed or locked open. When closed only the key can unlock the deadbolt from either the inside or outside. When the indicator is green, the deadbolt can be locked by turning the knob on the inside. Until the key is turned on the inside again, the deadlock operates the same way as a single cylinder deadlock, making it possible to open at any time from the inside.

Auto release deadlocking

When leaving the house you would usually deadlock the inside knob for security. If this lock is on your main entry door there is an added safety feature. Upon returning home and unlocking the Lockwood 005 from the outside, the inside handle is automatically released from its deadlocked position. This makes sure you are able to easily lock and unlock the deadlock from the inside with the internal knob.

Low Profile

Lockwood 005 deadlock low profile outside cylinder GoldThe external cylinder of this deadlock is partially recessed inside the door. This makes the outside profile much lower. In fact it has an outside profile of only 12mm, which is not only stylish but also makes attacking the lock much more difficult for burglars.

High security

The lock comes standard with Lockwood’s Kinetik Defence cylinders for added pick and bump key resistance. The cylinders can be changed to suit any Lockwood key making it possible to key alike all the locks on your home or business to the one key. A high security lock cylinder can also be used for extra protection against lock picking and key duplication.

Balanced steel bolt

The lock bolt is made from Stainless Steel and has saw resistant hardened inserts. As the bolt is shorter then most standard deadbolts, the Lockwood 005 is suitable to install where only a shorter bolt will work. If you have a glass panel next to your door strike, or just dont have the option of a large bolt hole, then the Lockwood 005 is a good choice. The lock bolt is adjustable to suit either a 60mm or 70mm door hole. This makes it an easy replacement for existing deadbolts, no matter what their backset is.

Stylish and functional

Our Brisbane locksmiths have plenty of stock in both Satin Chrome and Polished Brass and are able to fit this lock to your door at a time that is convenient to you. This is definitely a deadlock you will enjoy using.

How to Pick a Lock

How to Pick a Lock

lock picking made easy

How to Pick a lock

Picking Locks

Picking locks is the technique used to open a lock without a key by lining up all the pins or discs to allow the lock barrel to turn. Well, we have all seen it in movies. You just grab a bobby pin out of your hair and stick it in the lock and Hey Presto!! lock opens… Uhrrrrr If only it was that easy!

So how do you pick a lock? Well if you type “How to pick a lock” into Google you get 121,000,000 results!! So you don’t need me to tell you.  Sites on lock picking are all over the net.  Anyway here is the top YouTube video result for “how to pick a lock”.  This explanation is not from a locksmith!  It is just some guy who bought a lock pick set online!

Well, the reason for this post was not to show you how to pick locks. It was more along the lines of how easy are door locks to pick in Brisbane. I say Brisbane, because the types of locks used for a particular region, city, country, etc differ quite a bit. So lets use Brisbane as a case study, because that is where I live.

I will try to be as honest as I can with regards to just how easy or hard locks are to pick. Even though I pick locks professionally as a 24 hour locksmith, I still have a pretty good idea just how hard it is to pick locks for an amateur lock picker.

Lock pick set to pick locks you can buy online.

Lock Pick Set for sale on the internet

Lock picks and picking tools can now be purchased on the internet which will open a range of locks in Brisbane. Sounds scary? Well, yeah, it is very scary! A lot of people might not know this? Even if they do know, then it might be a case of, well, my neighbors have the same locks. Why would a burglar target my home or business? There is truth to this. A lot of break ins are just random and not targeted. So having a lock on your door that can be easily picked open does not mean you are going to get broken into. Neither does leaving your door unlocked.

Some places are targeted for break and enters. Especially businesses that keep a high dollar value of stock or that are a high value target for thieves. I often see business premises that are locked up with a low quality lock that could easily be picked by amateur thieves.

I was going to try to go through some of the common key operated door locks that are sold at the large chain hardware shops and let you know how hard they are to pick open.  But there is no point to singling out any particular lock.  Truth is, just about all the door locks sold by the major chains are easy to pick with tools readily available on the internet!!
Before information and tools was easily available over the internet, it was a different story. But the truth is the door locks have not changed in their designs. It is not that they are any more insecure then they were 20 years ago. It is just that it is a lot easier to buy lock picking tools and find the information to use them. So I would have to say that most of the door locks sold by major hardware shops are not secure enough to fit to peoples homes or business.

Entrance Lock Set you might buy at a Hardware Shop

There are a few door locks sold by the major hardware shops that are not easy to pick. They are mainly the Lockwood range of domestic locks with Kinetic Defence cylinders. The Kinetic Defence cylinders use a very simple and effective pin design that makes them harder to pick open. Many locksmiths can not even pick these locks and have to drill the cylinder out if they need to open a locked door. Our 24 Hour Locksmith can pick Kinetic Defence lock cylinders, using specialised tools that are not available over the internet.

Lock from hardware shop easy to pick

What are you getting when you buy a lock at a hardware shop?

Is price a good guide of a quality lock?

No! Many expensive key operated door locks sold in hardware shops are still very easy to pick the lock cylinders. Basically most of the pin tumbler locks operate in the same way and these locks are easy to pick with low cost tools.

Can anyone pick a lock?

Yes and no. The tools make it possible for anyone to pick a lock with a little practice. The more practice you have at picking locks, the better you will get. Picking locks is a skill that is learned over time and when you get proficient at picking locks there is a much higher chance of picking each lock you come across. As a professional 24 hour locksmith, our skills at picking locks have to be of the highest standards. We need to be able to pick every lock that we possibly can to perform our job. An amateur lock picker might only be able to pick a percentage of the locks a professional locksmith can.

Are commercial locks any harder to pick?

Standard Pin Tumbler Commercial Door lock Cylinder

Many standard commercial locks use the same pin tumbler mechanism as domestic doors. These standard locks are just as easy to pick as domestic locks.
There are of course high security locks that can not be picked with tools bought on the net. Many businesses do use high security lock cylinders and are secure from these types of attacks.
Just simply having a heavy duty shop front lock fitted to your door, does not mean that your lock can not be picked! The lock must be changed from the standard pin tumbler cylinder to a high security lock cylinder that can not be picked.

I have a registered key system.

Restricted registered key lockwood Australia

Registered Key by Lockwood

There are many types of registered key systems on the market. Some use a high security cylinder that is practically impossible to pick. These are the best lock cylinders to have on your doors. Why you would secure your doors with anything less is a mystery to me. The cost is not that high, and the fact that it can not be picked open with tools you buy online makes these locks more then worth their value.
Some types of registered key systems use lock cylinders that are easy to pick. While others are very difficult with off the shelf products you buy on the net. It is very hard to tell the difference between an easy to pick registered key system and a difficult to pick system. It is not about the quality of the lock or price. It mostly comes down to weather the locksmith sold it as a difficult to pick lock cylinder or just a “Registered Key Lock System”. Locksmiths who know what they are doing can make registered keys locks very hard to pick. Sadly, most locksmiths do not ensure registered key lock cylinders are difficult to pick at all.

I have a deadlock on my door

Brava deadlock deadbolt


Ummm Off the shelf deadlocks from hardware shops generally use the same Pin Tumbler Mechanism as other easy to pick locks. Deadlocks with a standard lock cylinder are no harder to pick with a tool bought over the internet then any other type of door locks.

Security Screen Doors

Security Screen Door

I have a $1000 stainless steel mesh door installed. It even stops attacks from “Bowling Balls” 🙂
I love that add!! If ever I get attacked by a bowling ball, I know I will be safe 🙂
Seriously, most of the security screen doors are installed with disc tumbler lock which is almost in the class of “Able to be picked with a bobby pin” These cheaper screen door locks might keep out flies, but spend $5.99 on the internet and buy a lock pick and you will have these doors open in a few seconds.
Screen doors also have a better lock cylinder that can be installed which is a Pin Tumbler lock. These locks are generally a little harder to pick. They are still easy enough to pick with tools you can buy on the internet.
Security screens can be placed onto a high security cylinder that can not practically be picked. You will only find the high security cylinders available from locksmiths.

Electronic locks

electronic lock Brisbane

Electronic door lock with key override

There are still very few homes fitted with electronic locks. Even though they are available at a reasonable price many locksmiths do not recommend them as a good alternative. Most electronic locks have their own unique vulnerabilities for which are not generally in the public domain so discussing ways to defeat electronic locks is out of the scope of this post.
One thing most electronic locks do have in common is that they also have a key override. If the override key is simply a standard pin tumbler lock, then being able to pick these locks is generally as easy as any other pin tumbler lock. This kind of makes any security feature of an electronic lock obsolete.

Electronic locks generally can be unreliable. Batteries go flat and many electronic locks just fail. Most electronic door locks have the batteries on the inside of the door, so a key override lock cylinder is an important feature.

Not all electronic locks are terrible. We fit a range of electronic locks that are reliable. We are careful to select locks that can not be bypassed or easily opened as many electronic locks can.

James Bond lock picking tool

James Bond lock picking tool

James Bond Lock picking

Impressioning tool for picking locks

Well, James Bond might not have the patience for this tool, but the idea of inserting a piece of aluminium foil into a lock to open it makes the imagination run wild. Walking up to a locked door and inserting a tool that just magically opens the lock is what everyone sees in the movies, so I guess this is pretty close to being a movie type lock opening tool. A lock only has to open once to let in a thief, or worse, so it doesn’t really matter if the lock pick tool isnt designed to last for very many uses.

This lock is opened using a method locksmiths call impressioning. Impressioning a lock works because the pins inside the lock bind when they are not in the correct opening positions. When the pins in the lock are correctly lined up, as they would be with a key, they no longer bind and are happy to just sit in the correct position. Impressioning works on a wide variety of lock types from old fashioned lever locks, safe locks, Yale locks, Lockwood locks, and many high security locks.

The tool used in this video is for a specific type of lock cylinder. They are called dimple locks. They are not known for high security in the first place, so this tool is a bit of an overkill as an opening technique. It is more of a gimmick then a serious lock opening tool.

Dimple key and lock

Dimple lock and dimple key

Dimple locks use a key that is flat on both sides and has dimples in the key which are a hole drilled into the key at the correct depth to match the lock pin size. There are only so many different hole sizes you can drill into a key like this which is why this lock impressioning technique works on this particular type of lock. There is not a great deal of difference in the height of the pins, so a piece of aluminium foil is all that is needed to set the depths.

These locks are generally not used in Brisbane, due to their low security and because they are rather simple to open. You do see these dimple locks on different types of devices such as steering wheel locks for cars, but generally not on house doors or anywhere that there is a need for more security.

I thought this was an interesting idea to share with people who are interested in knowing different ways to open a locked door. It might not be very practical, but it definitely has that James Bond appeal to it.
