Troubleshooting Common Issues
Sometimes, even after replacing the battery, your key fob might not work. Here’s what to check:
- Battery Orientation: Ensure the battery is installed correctly. The positive (+) side should typically face upwards.
- Clean Contacts: Clean the battery contacts inside the key fob with a cotton swab and rubbing alcohol. Corroded contacts can prevent the battery from making proper contact.
- Reprogramming: In rare cases, you might need to reprogram your key fob after replacing the battery. Refer to your owner’s manual for instructions.
“A common mistake people make is not paying attention to the battery’s orientation,” says automotive electrician, John Smith, “Always double-check that the positive side is facing the correct way.”
