The 4mm thick Ultion key will continue to engage long after thinner keys have bent or snapped. City Lock & Safe are also an Ultion Key Centre.

20-point drill protection

Both ends of every Ultion lock feature 20 hardened steel pins and plates each one positioned precisely to protect your lock from a drill attack.
