<human>:  How do I fix a broken lock?
<bot>: First, you need to identify what type of lock it is. Depending on the type of lock, the steps to fix it can vary. If it is a basic cylinder lock, you may be able to replace the cylinder or reset the lock combination. If it is a deadbolt lock, you may have to replace the entire lock assembly. For more complicated locks, such as electronic locks, you may need to get professional help to repair or replace the lock.
