Locks for UPVC and Composite Doors

Do you have upvc or composite doors on your house or flat? If you do they will, more than likely, be locked using a euro cylinder and, unless you have already changed them, it is very likely to be from an inexpensive range of products.

A basic euro profile cylinder

It will be relatively easy to pick or ‘snap’ (we’ll come to snapping in a moment), but it will also be very easy to replace and, without spending a fortune, you can make your home much more secure.

Master Lock and Safe Ltd sell replacement cylinders from major manufacturers such as Ultion, Evva, Eurospec, Union and Assa which are far more resistant to picking and bumping than an inexpensive lock.

We have fully trained engineers available to fit more secure cylinders to your doors. If you would like us to, we can fit locks to several doors which can all be opened by the same key. Fewer keys to carry!


Snapping a cylinder involves physically breaking the lock. Sounds difficult? Watch the video below:

But there is an answer. 3 Star cylinders from Ultion or Evva in either the EPS or ICS ranges are designed to snap in such a way that the lock cannot be unlocked from the outside.

They can be fitted just as easily as conventional euro cylinders by our engineers or are available for sale so you can do it yourself.

Ultion and Evva 3 Star cylinders are available from our retail premises at 23 Southbank Road, Southport or on line by following the links:
