Sometimes, even after replacing the battery, your key fob might not function correctly. Here are a few common issues and how to address them:
- Key Fob Not Working After Battery Replacement: Ensure the new battery is installed correctly with the positive (+) side facing up. Check the battery compartment for any corrosion and clean it if necessary. If the issue persists, the key fob itself may be faulty and require reprogramming.
- Key Fob Intermittently Working: This can be due to a weak battery connection, a faulty key fob, or signal interference. Try repositioning the battery or cleaning the contacts. If the problem continues, consider having the key fob professionally checked.
“A common mistake is installing the battery upside down. Always double-check the polarity,” says John Miller, a seasoned automotive locksmith with over 20 years of experience.
