- Remove the emergency key from the bottom of the fob.
- Insert the emergency key into the keyhole on the driver’s door.
- Turn the key to unlock the door.
- If the door unlocks, the battery in your key fob may need to be replaced.
Step 2: Check Fuse
If the battery in your key fob is not the issue, the next step is to check the fuse for the keyless entry system. To perform a fuse check:
- Locate the fuse box under the dashboard on the driver’s side.
- Find the fuse for the keyless entry system.
- Check the fuse for any signs of damage or burning.
- Replace the fuse if necessary.
Step 3: Check Wiring
If the battery and fuse are both good, the next step is to check the wiring for your keyless entry system. To check the wiring:
- Use a voltmeter to check for power in the wiring.
- Check the connections between your keyless entry system and the vehicle’s computer to ensure they are secure.
- If you find any loose connections, tighten them.
Step 4: Re-programming
If none of the above steps have worked, it may be time to reprogram your key fob. To reprogram your key fob:
- Insert the key into the ignition and turn it to the “on” position.
- Press the “lock” button on your key fob.
- Turn the ignition off, then back on again.
- Press the “lock” button on your key fob again.
