Solution

1. Preparation

Gather tools: screwdriver set, multimeter, replacement fob battery, fuse puller.
Disconnect the battery to avoid electrical shorts while working on the system.

2. Replace Key Fob Battery

Open the key fob using a small flathead screwdriver to pop it open.
Remove the old battery and install a new one (typically CR2032).
Reassemble the key fob and test the lock function.

3. Check and Replace Fuses

Locate the fuse box (refer to the owner's manual for specific location).
Identify the fuse related to the door locks and use a fuse puller to remove it.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the door locks.

4. Test Lock Actuator

Remove the door panel to access the lock actuator (use a screwdriver to remove screws and carefully detach the panel).
Use a multimeter to test the actuator for voltage when the lock button is pressed.
If there is voltage but no action from the actuator, replace the actuator.

5. Inspect Wiring and Connectors

While the door panel is removed, visually inspect all wiring and connectors linked to the door locking mechanism.
Look for any signs of wear, corrosion, or disconnection.
Repair or replace any damaged wiring or connectors as necessary.
