Locks are supposed to be a security feature that provides peace of mind, but when they don't work properly, they can cause frustration and inconvenience. Fortunately, there are several DIY options available to help unlock a door without the need for a locksmith.

One common problem with locks is when dust and dirt accumulate inside the lock cartridge, causing the pin to get stuck and preventing the plug from turning properly. To solve this issue, a lubricant such as WD-40, silicon-based lubricant, graphite spray, or dry lubricant can be used. Simply spray it into the keyway and insert the key to allow the lubricant to enter the locking mechanism.

Frozen locks can also be a problem, especially during the winter months. In this case, heating the key in a small container of hot water can help. Once the key is warm and dry, insert it into the lock mechanism and turn it slowly. Alternatively, a deicer or a hair dryer that blows hot air directly into the locking mechanism can be used.

Bent keys can also cause problems when trying to unlock a door. If a key has been bent due to being used as a box opener or can opener, it may get stuck in the lock. To straighten the key, a hammer can be used to hit the key on a smooth, hard surface. Care should be taken to remove only the curved part of the key to avoid flattening it. Using a side stool and placing a piece of wood between the keys of the hammer can also be helpful.

Blunt key tips can be another reason why a key won't turn properly. This can occur when a key is used for purposes other than unlocking a door. To fix a blunt key tip, a hybrid file can be used to remove excess metal and prevent the key from turning. It's important to use lubricant in the key and locking mechanism before attempting to turn the key again.

For those who want to avoid dealing with key locks that don't turn, a keyless entry system may be the solution. This system is becoming increasingly popular in modern cars and homes and allows users to unlock doors by entering a password, eliminating the need for a physical key.

Sometimes, a key may not turn because it hasn't been cut properly. In this case, a new key may need to be obtained. It's important to ensure that the key is placed correctly in the lock before proceeding with obtaining a new one.

If a key doesn't fit fully into the lock, there may be an obstruction, such as a corroded pin or a worn pin chamber. It's important to do research before attempting to fix this problem, as errors can damage the lock or door.

If a key can be turned but the lock does not turn, there may be a problem with the lock's mechanical system. The lock may need to be removed or replaced, or there may be misalignment problems or malfunctions with the lock cartridge.

In conclusion, dealing with a key that won't open a lock can be frustrating, but there are several DIY options available to solve the problem. These include using lubricant, defrosting the lock, straightening a bent key, fixing a blunt key tip, or even switching to a keyless entry system. However, if the problem persists, it's always best to seek the assistance of a professional locksmith to avoid causing further damage. However, if you are with Locksmith Tools, you do not need to worry about this situation anymore!
