A dead key fob battery can prevent you from locking, unlocking, or remotely starting your vehicle. Fortunately, replacing the battery is a quick and straightforward process that usually takes only a few minutes with the right tools.
Locate the small notch or seam along the edge of the key fob. Carefully insert the flathead screwdriver or prying tool into the opening and gently separate the two halves of the case.
Work slowly to avoid damaging the plastic housing or internal components.
Once the key fob is open, locate the battery and note its position before removing it. Pay close attention to which side faces up, as the replacement battery must be installed in the same orientation.
Carefully lift out the old battery without damaging the battery contacts.
Insert the new battery into the compartment using the same orientation as the original. Make sure it sits securely in place and that the battery contacts are properly connected.
Align the two halves of the key fob and press them firmly together until they snap into place. Check that the housing is fully closed with no visible gaps.
Press each button to verify that the key fob is working correctly.

If replacing the battery doesn’t restore normal operation, the key fob may require reprogramming or repair. A professional automotive locksmith can diagnose the problem, replace damaged components, or program a replacement key fob to ensure reliable operation.
