If you notice that your lock is not functioning properly, it is possible that it has been "bumped." Bumping is a type of attack that uses a specialized tool to quickly and forcefully open a lock. This can be done to locks on doors, windows, safes, and even cars. While bumping is relatively easy to do, it can be hard to tell if your lock has been bumped without special tools or training. There are a few signs that you can look for that may indicate that your lock has been bumped: The keyhole appears to be damaged or deformed in any way The lock feels loose or wobbly when inserted into the keyhole The lock does not properly engage when locked The lock can be easily opened without a key If you notice any of these signs, it is possible that your lock has been bumped and should be replaced. Bumping is a serious security risk as it can allow someone to easily gain access to your home, office, or car. If you suspect that your lock has been bumped, be sure to contact a locksmith or security professional as soon as possible.
