If the problem is more severe, and the key has been bent, you may have to get it straightened by a professional. A professional locksmith will employ a special tool that has an angled edge that fits into the groove that runs along the edge of the key. This kind of tool can't be found in hardware stores. However you can buy an entire set of necessary tools online or from locksmiths.

Another possibility is that the lock has become dirty or contaminated. Over time, dust can accumulate in the lock the cylinder, which may cause the pins and springs to swell up. In this situation you'll be required spray the lock with graphite spray or a silicone-based lubricant to get rid of it and then reposition the pins back to their original position.

It could also be an issue in the event that the key is damaged. Keys can wear down over time through repeated use, which will cause the groves to wear down or even become smoother. This could result in the key not fitting properly into the cylinder, so it is important to be aware and check regularly that your key is fitted correctly.

Locks can freeze during the winter months. This can stop the springs and pins from moving when keys are inserted.

Sometimes, the key won't rotate in a lock if it's damaged. This could happen when you've lost your key, or if it is broken inside the lock. Instead of trying to pull it out of the lock, which could cause the broken piece of the key to move further into the mechanism and make the problem much worse, try using needle-nosed pliers to take it out of the lock. Be careful not to scratch the lock by cutting off any of the broken key using the pliers.

It's also possible that the lock isn't aligned properly and this could cause the door to not latch properly. If you happen to have an extra key, this could be tested in the lock to confirm that it works correctly and isn't the issue.
