When you start to notice weird things going on with your lock, it might be time to start thinking about finding an expert slotenmaker Voorburg to get it repaired. Even if you’re not sure what exactly is going on with the lock, there are some tell-tale signs that might help you realize whether or not you need to call someone in immediately. Here are signs your lock may need repairing as soon as possible.
1) The key doesn’t work in the keyhole
This seems obvious, but there are times when you think that key just doesn’t want to turn all of a sudden. If you find yourself unable to unlock your door, give us a call right away. A lot of time and stress can be saved if we come out right away, rather than you struggling with keys trying to fix it yourself.
2) You can tell someone else has been trying to get in
Maybe you’re sure no one has tried to get in, or maybe it just seems so unlikely that someone else would try. But, if you look at your lock and see obvious signs that someone has been trying to jimmy it (scratches, dents, etc.), contact a professional immediately.
3) You can see marks around the keyhole
When you stick a paper clip into that hole, and can tell there’s damage around it, then it’s time to call in professional help. Picking that lock isn’t as easy as television makes it look! Besides, if you don’t know what you’re doing and mess up, you can make things worse.
4) There’s rust on or around the lock
Rust on or around your door’s lock means it might be time to call a professional. Rust can be caused by moisture in or around your lock, which can lead to rust appearing on other parts of the door and potentially weakening its overall strength. A professional should be able to determine whether moisture has affected other parts of your door, as well as determine if you need new hardware.
5) The door sticks
If you notice that one of your doors sticks when you try to open or close it, it could be that an alignment issue with the strike plate on your door or frame. You should have both inspected and adjusted by a professional. A misaligned strike plate can also cause undue wear on your door’s locking mechanism, which may need replacing in time if not corrected soon.
