What to Do When Your Key Breaks Inside the Lock?
Broken keys are something a residential locksmith encounters on a regular basis. Consider the amount of pressure a key must withstand, it's no wonder they break eventually. Prevention is best and, if you notice that one of your keys is starting to bend, it's best to avoid using this key and either replace the lock, have it rekeyed, or have a new key cut. Keys should only be copied from original keys that are in very good condition. Otherwise, any defects will simply be carried over to the new key. If, for whatever reason, you end up with a broken key stuck inside a lock, here are some things you can try.
