A letterbox lock (also called an automatic cylinder) is, as the name suggests, used for letterboxes, but also key boxes, slot machines, cash boxes and lockers. We have many different letterbox locks in our range. If you need a new one, we advise you to take the old one with you so that you are sure of the correct size. If you have lost the keys to your automatic cylinder, you can check whether there is a number on the cylinder core. We can make keys by number for many of these types of cylinders. Always take a photo of the lock, that makes it a lot easier for us. In such a case you do not need to replace the cylinder. We are of course always available in the store for advice.
