Essentially lock tumblers are made up of three main components: springs, driver pins and key pins.
Inside the lock, there are several vertical shafts that each contain a spring, a driver pin and a key pin. The springs push down on the driver pin, which in turn presses down on the key pin to ensure all the pins are pushed down to rest uniformly on a ledge at the bottom of the tumbler. When a key is inserted, it pushes through the key pins that rest at the bottom of the lock and the springs allow the pins to move through the vertical shafts. If the correct key is used, the driver pins will line up along what is known as the shear line and the lock will unlock. Using an incorrect key, as we all know, does not work as the driver pins are not aligned.

Tumbler replacement – AKA re-keying a lock:
Often referred to as ‘re-keying a lock’, a lock tumbler replacement involves replacing the pins inside the lock so that all existing keys no longer work. This can be useful in a number of different scenarios, for example if you’ve lost one or all of the existing keys or you want to prevent access for someone that has an old key. It’s also a great way to up-date security without having to replace the whole lock.
Whenever you move into a new property, whether it’s a new home or a new commercial property, here at Quickly we always recommend this option. It saves the hassle and expense of replacing the whole lock but prevents previous owners or tenants from having access to your new property!
Master key tumbler replacement:
A master key, as its name suggests, is one that will open a number of doors. In order for this to work, an extra pin is included inside all locks (called the master pin). Replacing this key or tumbler is a service that we can offer, enabling you to update your current locks to accommodate a master key or to replace an existing master key with added security.
It’s not all rosy though. While master keys offer obvious flexibility, these locking systems are slightly more susceptible to lock picking and therefore burglary, so our experienced locksmiths always recommend implementing additional layers of security on these doors. That could be a security camera, additional locks or other kinds of security systems. If you would like to discuss adding to your current security, our experts are available to offer friendly and trustworthy advice, just give us a call.
