When to Seek Professional Help
While DIY battery replacement is often feasible, there are situations where it’s best to consult a professional locksmith or automotive technician:

- Protect from Moisture: Water damage can severely compromise the functionality of your key fob. Keep it away from spills and excessive moisture.
- Minimize Battery Drain: Avoid unnecessary use of key fob features, such as the panic button or trunk release, as this can drain the battery faster.
