Swan Lock Services Deadlocks can only be operated by key from outside and by turnknob on the inside.

Unlike a deadlatch there is no automatic locking.

This means that unless you lose the key, you cannot lock yourself out.

Positive Deadlocking is achieved by turning the key you in turn drive the bolt to either the locked or unlocked position.

Positive deadlocking guarantees the lock is deadlocked everytime.

So give Swan Lock Services a call or email now to gain peace of mind over your possessions.
