Lock Snapping - The Facts


How to Measure a Cylinder Lock

The lock already in your door is not necessarily the best size, watch this video to see how easy it is to get the right size of lock in just a couple of minutes.

Full Written Guide

Its very easy to mismeasure a cylinder lock whilst its in the door. We strongly recommend taking it out to get an accurate measurement. Be careful if you use a tape measure and not a ruler as the end of some tapes can make it tricky to get the right size.

Cylinders come in 5mm increments, do not reduce the size of your cylinder if your lock sticks out of the existing handle by less than 5mm. PVC french doors sometimes have special central sections making it very difficult to remove and refit a cylinder lock. Please call for advice.

Don't forget, our phone lines are open 6 days a week, so for advice on measuring, fitting or any aspect of door and window security please call one of our advisors.

How to Fit a Cylinder Lock

Fitting your new ultra-secure lock can be as easy as measuring it. All you need is the key and a screwdriver. Watch this video to see how.

Full Written Guide

In the edge of the door there will be a fitting screw, this needs to be taken out and put to one side.
If you are unable to access the fitting screw (possible in a french door application) then it is wise to consult a qualified locksmith.

To remove or insert a euro-cylinder the key must be turned slightly to line the tongue of the central cam up with the body of the lock, this will enable the cylinder lock to slide in or out. Getting the amount of key turn may require a bit of trial and error, but usually it requires a 15 to 20 degree turn either to the left or right, this is shown clearly on the video. If there is any resistance to removing the cylinder it can help to just loosen the handle screws - sometimes a slightly offset handle can put pressure on the cylinder making it a little stiffer.
