How to change a euro lock in UPVC door

Step 1 : Remove the fixing screw (sometimes this can be a allen key ) that is located on the side of the door, in line with the bottom of the cylinder.

Step 2 : The key is needed to turn a cam that is holding the cylinder into the door, with a pulling movement, turn the key slowly until you feel the cylinder pull out of the door. Simply replace the cylinder, making sure the keys are inserted to make the cam flush, then replace fixing screw.

What size lock??

Easiest way bring the lock into us. If you can't do that measure in millimetres both sides up to the black cam. Sometimes they are equal ie. 40mm/40mm, sometimes not ie. 40mm/50mm. We stock the full range and they come with 3 keys, extra keys can be cut while you wait.
