Lenlok make a large range of locks for garage doors. When you are thinking of changing your roller door lock, dont go past this Lenlok roller door lock. This is the heavy duty model with removable cylinder.
As locksmiths we are often called to change or rekey locks on roller doors. When a client pays us good money to change the keys on a roller door lock, they want to be sure the old keys will no longer work in the lock.
The problem with most standard roller door locks is that they use a wafer or disc lock which offers little security. Even when the combination of the lock cylinder is changed there is a chance that another key will still operate in the lock. This is due to the poor tolerances in the cylinder, soft materials used in their construction, low number of disc combinations and wear in the lock cylinder.
As there are problems with rekeying roller door locks (and other similar lock designs), we will usually recommend that the lock be replaced with a more secure type of lock. This is not because we want to sell more locks. It is due to the high chance of an old key or random key working in your roller door.
The Lenlok roller door lock does not look too much different from standard roller door locks. Although there are a couple of features that make this lock far better then standard disc type locks.
The Lenlok roller door lock has a completely replaceable cylinder assembly. There are various cylinder types that can be fitted to the lock. The more secure locking cylinder is the pin tumbler cylinder. The pin cylinder uses pins as used in most other house and commercial lock cylinders.
A pin cylinder can also have its barrel changed to suit a range of registered key systems. It can even be replaced with a high security lock barrel for the best security. The standard pin cylinder can be changed to suit a Lockwood style C4 key. The C4 key is the most common key used in Brisbane for house doors and commercial doors. It is possible to have a house changed to suit just one key. Even the garage door can be on the same key.
This lock also comes with 2 locking functions. For a garage you want to access from the inside such as one connected to the house, the lenlok roller door lock can be set to be opened with the turning knob on the inside of the lock. This gives free access to open and close the lock from the inside of the garage.
If the garage has no other access doors or the lock is fitted to a storage room, the lock can be set to operate as a deadlock. When the lock is operating as a deadlock, the inside turning knob will no longer open or close the lock. The lock must be opened and closed using the key from the ouside or the inside. Deadlocking adds increased security for storage areas. When unlocking with a key from the inside a “reverse key” is used. The reverse key only operates the lock on the inside of the door. This is because a reverse broached key only will slide into the inside of the lock.
There are a few different model designs of the Lenlok roller door lock. They are designed to match existing roller door locks. The main difference is the length of the arms and size of the face plate.
