We’ve all been there before. You’re trying to unlock your door, and the key snaps in half. It’s a frustrating experience, and one that can leave you feeling helpless. But why do keys break in door locks? Here are some of the most common reasons:

1. Worn down keys: Over time,keys can become worn down and weak. This is especially true if they are made of softer metals like brass. As the key wears down, it becomes more likely to break when inserted into the lock.

2. Poorly cut keys: If a key has been poorly cut, it may not fit properly in the lock. This can cause the key to break when you try to insert it.

3. Rust: Rust can cause keys to break for two reasons. First, rust can cause the key to become stuck in the lock. Second, rust can weaken the metal of the key, making it more likely to snap when inserted into the lock.

4. Cold weather: Cold weather can cause keys to break for two reasons. First, the metal of the key can contract in cold weather, making it more likely to snap when inserted into the lock. Second, cold weather can make the lubricant in the lock freeze, making it more difficult for the key to turn.

5. Jammed locks: If a door lock is jammed, it can put extra stress on the key, causing it to break.
