Cordless Key Cutting Machine

Having a key cutting machine that works anywhere without being connected to mains power or power from our locksmith vans comes in very handy. You can take the key cutting machine to any location, which can save a lot of time.

This is an Ilco key cutting machine which I purchased about 25 years ago. It was a dual voltage 240 volt and 12 volt machine. The original motor stopped working quite a few years ago and a replacement 12 volt motor was used for some time. Recently the 12 volt motor also stopped working. So it was time for an upgrade.Back of drill clamp with throttle key 24 hour locksmiths Brisbane

Using a cordless drill would be a practical way to have a truly cordless key cutting machine. Mounting a drill was a fairly straight forward process. There were 2 options to mounting the drill. Either using the drill connected directly to the drive shaft of the machine, or via a belt.

I chose the belt drive, as mounting the drill directly to the drive shaft had two large problems. It would increase the size of the machine as the drill would have to be added to the side of the key machine. There was also vibration issues as the drill and driveshaft would not align perfectly. A joint between the drill and driveshaft would have to have been used.

A simple drill holder and clamp was designed and made on a 3D printer. A throttle key was also made to turn the drill motor on and off and to control the speed. The drill clamp was made from PETG which should withstand the heat of a hot van in the Brisbane Summer. Holding the drill in place does not require a large amount of clamping force so a PETG clamp works well.

Code keys for safes

Code keys for safes

Many locks are stamped with a key code number but key codes alone are of little use. Extra information is usually needed to cut a key to code. A call to cut keys for room safes in a hotel was one such call that extra information was needed.  With no code information available these code keys needed a different approach.

key cut to code for safe lock code keys

Often a brand name of a safe, the make and model of a car or brand of furniture is also required to cut a key to code. The brand of the hotel room safes were an after market obscure brand that had no link to the locks that were fitted to the safes. The safes locks were all marked with a four number code between 1000 and 6000. The code numbers were a bit of a give away as to their meaning. The numbers seemed to be a direct code. A direct code is a code number that is also the cuts of the key. Such as 5226.

As there were quite a few safes to cut keys to, being able to cut them to the code number would save time and money for the hotel owner. The problem with these safes was that there was no reference to the space and depth dimensions of the keys. If you do not know accurately the space and depth of the keys, then cutting keys accurately is not possible.

In order to cut the keys to code, one of the locks was removed from the safe. The lock was then taken apart carefully, not to disturb the combination of the lock pins.

Once the lock was apart, the key dimensions were deciphered and a code card made up for a code machine. This is a fairly old code machine that is used in one of our mobile locksmith vehicles. This code machine is a punch machine and uses no electricity. It is perfect for use on a job site to cut keys to code.

Once the code card was created, the keys could easily be cut to the code numbers on the front of the locks.

The keys all worked perfectly and the hotel owner was very happy that his safes could have new keys cut for them easily. Now if ever a key is lost for these safes, a new code key can quickly be produced from the code stamped on the lock.

Most codes keys can be cut a lot simpler then the keys for these safes. If keys are needed to code or even if no code is present on the lock our 24 hour locksmiths in Brisbane are always able to help.

Milner Safe Lock

Milner Safe Lock

Milner safe lock 3D printed replica

A milner safe is very easy to identify just by looking at the key hole. The distinctive 2 keyhole slots will give away the type of lock used in the safe every time. Milner were very popular safes for very good reason. They offered a high level of pick resistance and resistance from brute force attacks.

Usually the ingenuity of these old safe locks is only seen by locksmiths who service these safes and cut keys for them. Being able to replicate the lock easily on a 3D printer gives people a chance to see just how these locks work and allows them to build their own high security safe lock.

This Milner replica safe lock has a few changes from the original. The biggest noticeable difference is that the lock does not have a curtain. The curtain is an internal piece of the safe lock that serves 2 main purposes. It acts as the bolt throw and it shields the levers and inner working of the lock to make lock picking much harder. The curtain could not be 3d printed strong enough to make it work in this model. Instead the bolt throw uses the end cut of the key.

The key is made much larger simply to add strength. A thin plastic key just isnt strong enough to work.
Interestingly, the original Milner keys were made from cast brass. A cast brass key is very strong! Modern steel keys have the flag welded onto the post. The weld in modern keys is a weak point and often causes keys to break inside a safe. If you can find a locksmith who has cast brass keys, they are a much better alternative for these safes.

The body of the lock is made in three sections. The bolt is inserted from the bottom of the lock and the levers are inserted from the top. A top and bottom plate hold the lock together.

As a locksmith in Brisbane I still see a lot of these old Milner safes still in operation. While they might not have the same resistance to modern attacks as more modern high security safes, picking the lock on a Milner safe is still a very hard endeavour which takes a lot of skill. Most Brisbane locksmiths would not even consider picking a Milner safe lock.

Euro Cylinder Repinning tool

Euro Cylinder Repinning tool

Euro Repinning Tool

 

Euro Repinning toolThis is a post mainly for locksmiths.  Euro cylinders can be a pain when a top pin falls out.  Trying to get a pin or all the pins back into a Euro cylinder can be a challenge.  The pins have to be put back in from front to back and a regular follower will not work.  You have to repin the lock using a “wire” type follower.  It is just a lot of hassle.

3D Printed Euro Tool

This is a simple tool i use to repin euro cylinders.  It is 3D printed and the one shown here is made from PETG plastic.  It takes about 10 minutes to print and you can print more then one at a time.  I actually reccommend printing a few at a time just to give the plastic time to cool as it is printing.   You can also print it using a 3D printing service.   You can download the STL file here >– Euro Repinning Tool –>

Easy to make locksmith tool

It would also be easy to make this tool from an existing lock barrel.  You really need a lock barrel with a long back (or front) that will stick out of the cylinder a bit when the tool is inserted.   You would need to mill out the slot in the centre which might be difficult.   The printed tool is easier to make and easier to replace.

To use this tool

  • make sure the springs do not stick up too far above the shear line.  Springs sitting flat at the shear line are preferable.
  • Insert top pins into the pin chambers of the repinning tool
  • insert the tool into the lock and rotate so the pins and springs are aligned
  • line up the pins with the top pin chambers and push the pins down with a pick or piece of stiff wire.
  • rotate the repinning tool so the top pins line up with the slit in the tool
  • insert a euro follower into the slit in the tool as you would with a lock barrel
  • remove the tool.
  • Insert barrel with correct bottom pins

Euro Repinning tool and lock

Works on all lock spacing

The barrel i am using has no spacing markings.   For me it was not needed as it is just a simple matter to line up the pins.  If the lock you are repinning has different spacing to the tool, it is simple to pull the tool out slightly as you are pushing in the pins.  The euro repinning tool works on different spaced locks.

5 or 6 pin

You can use the tool on a 6 pin lock even though it is a 5 pin tool.   You load the first 5 pins.  Then you load the tool with the last pin only.  The tool will push down all the front pins as the last pin is loaded.

Hope this might help some locksmiths out there.   Have fun repinning these locks!

3D Printed Lock Barrels Brisbane

3D Printed Lock Barrels Brisbane

Changing lock barrels to suit any key 3D printed style

Are you one of those people who has been lying awake in bed just pondering the question “Can a lock barrell be 3D printed ?”  Well your question has now been well and truly answered.  Our 24 hour locksmiths have successfully 3D printed a range of lock barrels in different broachings.  Broaching to suit even high security registered key systems!

   3D printed lock barrel Brisbane locksmith       While these lock barrels are made of plastic, it is possible and cost effective to have the barrels 3D printed on a higher end metal 3D printer.  A metal printer can make the lock barrels as well as the entire locks out of materials such as Brass or Stainless Steel.  With additive manufacturing hardened anti-drill obstructions can even be added to the lock barrel.  This would give the lock a higher degree of security then many standard lock barrels.

Why would a locksmith want to 3D print lock barrels? Lock barrels are easily replaced in most locks.  A new lock barrel can be added to a lock to match the broaching of a different key.  Replacing all the lock barrels for a series of locks can make the locks all work on a new uniquely warded high security key.   The ability to reproduce a lock barrel to match a key system can unlock lucrative opportunities with already installed security key systems.

IMG_5008The bigger picture is that smaller companies can manufacture a lot more unique products that either did not exist or were not available or practical to manufacture using other techniques.

As additive manufacturing matures the security a locksmith can offer their customer becomes much more unique.  Custom broaching for locks is just the start.  Completely new lock and key designs can be prototyped quickly and manufactured on demand.  Where once locksmiths were tied to security key systems manufactured by large multi-national companies it is now becoming possible for small companies to manufacture on demand security products to suit a specific customer.

While Our plastic lock barrels might just be prototypes,  Production 3D printed parts are not far away.
