A Lock Cylinder is the part of the lock that does most of the work.

We usually don’t give that much thought to how the magic happens, do we? You put in a key, turn, and you have access to what you need. Or you stop someone else trying to get access.

In most cases, a lock cylinder is essentially made up of pins and a core/ barrel for the key. It sounds so simple. 

Yet think about it. This same Lock Cylinder technology has to work for padlocks, security screen locks, sliding glass door locks, locks on suitcases, in mortice locks and locks in doorknobs. So many different locks in different environments all over the world. For the best service and advice for the right cylinder for your locks, just contact our experienced team at Jim Roberts Locksmiths for the best service and advice!
