Lockdoor is a CX5 high security lock and cylinder dealer. CX5 cylinders feature top pins, side pins and a unique waved line milled right into the keyway to provide maximum protection. CX5 key control policies are strictly enforced and keyways are geographically managed to prevent the widespread availability of specific key blanks. Duplicate keys are only obtained with authorization card and signature verification.

It starts with the key!

CX5 high security technology starts with the unique waved security groove side milling on the key. This innovative concept activates internal side pins which control an auxiliary locking bar. The security groove allows for hundreds of possible independent keyways for each key profile.

Managed Key Control

CX5 key control policies are strictly enforced and keyways are geographically managed, preventing the widespread availability of specific key blanks. Duplicate keys are obtained with an authorization card and signature verification.

Multiple Locking Points

CX5 cylinders have a secondary point of locking control which results in a key cylinder that is virtually bump proof and pick resistance.

Added Internal Protection

CX5 cylinders are made with hardened steel pins. This decreases the likeliness that top pins or sidebar pins can be compromised by drilling or other physical attacks.
