At Alexandra Locksmiths we are often asked “What locks should I have on my PVC front door?”. 

Most PVC doors are fitted with a multi-point locking system. This is a lock that when you lift the handles up, throws locking devices from the lock mechanism in the door into strike plates situated on the frame. It is important to remember that you also need to turn the key in the cylinder to fully lock the door which also prevents the handles from moving and unlocking the lock.

For more information regarding your PVC front door, multi-point locking system, lock, cylinder or handles call Alexandra Locksmiths Ltd on 020 8883 1555 or 020 8364 2000 and speak directly to a locksmith or email some pictures of your existing locks on your door to us at
