A soiled or dirty lock is also a possibility. Dust can accumulate over time in the lock cylinder and cause the springs or pins to get stuck. In this situation you'll be required to spray the lock with WD-40, graphite spray or a silicone-based lubricant to clean it out and then reposition the pins back to their original positions. It may also be a problem in the event that the key is damaged. Keys are worn down over time by repeated use, which will result in the groves wearing down or even become smoother. This can cause the key to not fit in the cylinder. It is essential to check regularly to ensure that the key is fitted correctly. Locks can freeze during the winter months. This will stop the pins and springs from moving when keys are put in. This can be a frustrating issue however it is usually solved by warming the lock by using hot water and then re-lubricating it.

If this happens often, you may want to think about hiring a locksmith to take a look at the lock to see whether they can help.

This could happen if you've lost your key or it is broken in the lock. Instead of trying to fish keys out of the lock, which could result in it being forced deeper into the mechanism and make it worse, use needle-nosedpliers to remove the key from the lock. You should be cautious not to cut off the broken piece with the pliers or you could cause damage to the lock. It's possible that your lock isn't aligned properly, which can cause the door to not latch properly. If you have an extra lock key, you can test it to make sure that the lock is operating properly. If you discover that the lock isn't aligned properly, tightening the screws around the strike plate will solve the issue and allow the lock to function normally.

This issue can be fixed by using the lubricant based on silicon or graphite to cover the pins of the lock. This will allow them to move up and down in a normal manner.

The Cylinder is Rotating Hairpin vortices may form when a cylinder rotates in a confinement space. These vortices can exert significant forces on the cylinder rotating. The forces are proportional to the curvature radius that is dimensionless x and the confinement factor k. The simplified model that is presented here predicts the effect of these parameters on the force and torque of the cylinder that is confined. The cylinder's head, tube and main body are composed of aluminum alloy. If you are able to insert your key and turn it but the lock does not rotate, the cylinder may be defective. Rekeying the lock could fix this problem. You can purchase kits to do this online or in a lot of big box stores.
