Lockwood 001 Deadlatch for metal frame doors
The Lockwood 001 Deadlatch is a well known lock in Brisbane. It has been a good choice for houses in Brisbane for over 20 years. The wooden frame version comes with a door frame strengthener that reinforces the the door frame and gives greater holding force which makes it much harder to kick the door in when this lock is installed properly.
The metal frame version of the Lockwood 001 is identical to the wooden frame version. Except the metal frame 001 comes with a metal frame strike.
The metal frame strike comes in two pieces. It is in some ways similar to the wooden frame version in that the inside frame of the metal frame strike is where the holding force is obtained. The outer housing of the metal frame strike is attached by two screws to the inside frame.
The inside frame of the strike is screwed to the metal frame with metal thread screws. Holes are drilled and tapped into the metal frame of the door. It is these screws which provide the entire holding force for the strike. If the door was to be forced or kicked, it is these screws tapped into the metal frame which hold the strike secure.
Since the screw holes of the metal frame strike are so crucial to the security of the lock, they are one of the most important installation steps. An incorrectly drilled and tapped screw can compromise the metal frame strikes’ ability to stop an intruder. Of course I would only recommend using a trade qualified locksmith to have this lock installed. In fact it is against the law in most situations to use a handyman or non locksmith to install this type of lock.
The Lockwood 001 fits to most apartment doors the same way it does to a standard wooden door. There are however a large number of requirements for apartment or unit fire doors that have to be considered when installing a Lockwood 001 deadlatch in this situation. Fire doors internally are very different to wooden doors.
The Lockwood 001 is able to be deadlocked from the inside. The way this works is that the inside knob is locked with the key. Once locked from the inside it can not be opened without the key from either side. A red or green indicator on the inside of the the knob can alert you to the inside deadlatch being activated.
Once the key is turned and the inside knob is locked, the door can be pulled closed. If someone were to break in to your apartment through a window, the door would not be able to be opened without the key.
On returning home and opening the 001 from the outside, the inside deadlatching will automatically kick off. So the inside knob will be free to turn so you can exit the door. This is to help prevent you from being locked inside your apartment.
The Lockwood 001 uses a standard Lockwood key. The lock can be clanged to suit other keys in your apartment. It can also have lock cylinders or barrels replaced to suit most high security locking systems.
The standard cylinders use Lockwood’s Kinetic Defence pin and cylinder design. This does make the key feel rough to insert. This is especially noticeable when the key is inserted into the inside locking knob cylinder as it is spring loaded. The rough feel of the key being inserted is a trade off for added security to protect against lock bumping and lock picking. We have to give Lockwood credit for trying to make their locks more secure from simple opening techniques, so a lock that does not feel smooth is a small price to pay.
As the Lockwood 001 metal frame strike is one of the only deadlatches that can be fitted to most apartment doors there is not much to compare it to. This is a lock that has been tested by time and has performed very well protecting our homes. It is a good choice for your Brisbane apartment or unit door. Always use a qualified locksmith when installing this lock. There are quite a few laws and regulations that do need to be followed regarding its installation.
