There are a whole range of UPVC lock types available on the market. Whether you have an exterior door that you want to secure or you have interior doors that you want to be able to lock and unlock, you will find an option to work for you. 1. Multi point UPVC locks When a handle is turned, a series of roller cams secure the door. The handle can either be locked in place by a key or simply turned from the inside to lock the cams in position. The more cams that are in place down the length of the door, the more secure the system. 2. Keyed UPVC door locks Classic keyed systems will tend to incorporate a cylinder system.

This type of lock of course requires a key to be able to lock and unlock it, so you can be sure that it will be harder for a thief to get in. It is typically installed on storm doors, patio doors, and any other type of doors that need to be safely secured.
