High Security Locks

A strong lock in a weak frame is not high security, so we look at the cylinder, the bolt, the strike, the hinges and nearby glass before suggesting anything. The pages here explain each layer in plain words and where it belongs on your property.

Which one do I need?

High Security Locks

Cylinders and deadbolts built to resist picking, bumping and drilling, keys that cannot be copied without authorisation, and safes opened or installed.
