3. Check and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Use the fuse diagram to identify the fuse associated with the central locking system.
Remove the fuse using pliers and inspect it for continuity using a multimeter.
If blown, replace it with a fuse of the same amperage.
