Common Issues When Replacing a Mazda Key Fob Battery
While replacing your Mazda key fob battery is typically straightforward, you might encounter a few common hiccups:
- Difficulty separating the key fob halves: If you’re struggling to pry open the fob, ensure you’re applying pressure in the correct spot with the screwdriver. You might need to apply slightly more pressure than you think.
- Key fob doesn’t work after battery replacement: Double-check that you’ve inserted the new battery correctly, with the positive (+) side facing up. If it still doesn’t work, the battery might be faulty, or there could be another issue with your key fob.
