This range of thumbturn locks carries an amazing security specification for such a small part of the door! The anti-snap resistance design is an advancement on the 'break-line' found on most thumbturn cylinders.

The euro-lock cylinder is found in just about all uPVC/double glazing type doors and the vast majority of them are vulnerable to lock bumping and lock snapping.

These replacement thumbturn cylinders enhance the security of your door and are so easy to fit that any DIY novice can do it in minutes!

If you need extra keys then you can purchase these from us (send a picture of the card to us on email) or even timpsons on the high street (card will be needed).

Measure your existing thumbturn cylinder to find the two sizes as shown in this diagram (sizes are to the centre of the screw hole).
