A lock keeps a door secured until it is opened with the right key.
The idea
Lock is countable: a lock, two locks. A key fits a lock.
Examples
- The lock on the front door is broken.
- This key fits the kitchen door lock.
- We need a new lock for the back door.
- Turn the key in the lock slowly.
- The two doors have different locks.
- Can you check the lock before we leave?
