However, if the problem is more severe and the key has been bent out of shape, it may be necessary to have it straightened professionally. A professional locksmith will use an instrument specifically designed to straighten the keys, which has a curved end to fit into the groove that is recessed on the tip of the key. This type of tool cannot be found in hardware stores. However you can purchase an entire kit with the essential tools online or from an experienced locksmith. A soiled or dirty lock is a different possibility. As time passes, dust will build up in the lock's cylinder, which could cause the springs and pins to seize up.

A key can be worn down with time due to frequent use, which could cause the groves to wear down or even become smoother. This could cause the key to not fit in the cylinder. It is essential to check regularly to ensure that the key fits properly. In colder weather locks can freeze which will prevent the springs and pins from moving when the key is put in. This is a problem that can be frustrating however it is usually resolved by warming the lock up with hot water and applying lubrication. If the lock is damaged beyond repair, or has frozen the lock, it will have to be replaced. 3. The lock isn't turning It can be frustrating to find locks that don't turn or open. If it occurs frequently, you might consider getting locksmiths to examine the lock and see if they can help. This isn't always needed, as some problems can be solved by yourself.
