I have a key with your name on it. Can I take this to a closer locksmith to get copies cut?

Possibly not as this usually indicates that the key belongs to a keying system needing authorisation before providing additional copies.

No, John Barnes provides a wide range of locksmithing products/services and security solutions. We cater all your needs from barrel bolts to padlocks; from bike chains to electric strikes; to bathroom products and accessories including grab rails for the elderly.

What is the difference between a deadbolt and a dead latch?

A deadbolt is a type of lock that cannot be rotated without a key or an internal knob. The bolt is not spring loaded, unlike the dead latch. The dead latch has a bevelled bolt (flat on one side and curved on the other) and self-latches when the door closes.

How do I know which lock I need?

Not all locks fit all doors as there are a number of factors to consider.
