Who has keys to your home? Around 5% of home burglaries occur because the intruder has a key, which is why the security experts at Yale recommend that you update the locks when you move property – and it’s not as hard as you may think. Replacing the lock cylinder is an effective and easy way of making your home secure without having to change the entire lock or door. By simply upgrading the rim cylinder in your nightlatch, or the euro profile cylinder in a multi-point lock, your home can be secure in less than 10 minutes.Nightlatches are used on external timber doors and a good way of improving your security is by fitting a rim cylinder that meets the British Standard (look for the Kitemark on lock packs and the lock itself). You can replace your cylinder by simply unscrewing the nightlatch, removing the existing cylinder and replacing with the British Standard version. All rim cylinders are a standard size, so you should be able to replace your existing cylinder easily. If you have a PVCu or composite door, then you can upgrade the euro profile cylinder in your multi-point lock to a British Standard cylinder (again, look for the Kitemark on lock packs and on the lock itself). This is also an easy DIY job and will ensure the cylinder in your PVCu or composite door complies with the latest British Standard. By upgrading your cylinder you can be assured that your new home has the very latest security protection for added peace of mind.
