Make sure that you don’t leave keys in the back of the door, allowing thieves easy access. Keep your house keys away from the door.

Don’t keep your car keys on display. Find an out of sight drawer or cupboard. Also, if you have keyless entry on your car consider keeping them in a metal tin to avoid signal boosting thefts.

How To Measure Up For New Locks

When replacing the locks you need to measure the euro cylinder in your door. There is an explainer video below. But in short, remove the lock from your door and measure from the securing screw to the end of the lock barrel. Once each way.

For example, a lock measurement could be 40mm x 50mm.

It is important to measure the locks accurately because if they are too long they will stick out of the handle and will be unsightly. If you measure too short then the barrel will sit in the handle and the door will be hard to unlock.
