Signs Your Key Fob Battery Needs Replacing
Before you grab a new battery, it’s wise to make sure that’s actually the problem. Here are some telltale signs that your 2004 Land Rover Discovery key fob battery needs replacing:
- Decreased Range: Are you finding yourself having to stand closer to your vehicle to lock or unlock it? A weak battery can significantly reduce the key fob’s signal range.
- Intermittent Functioning: Does your key fob work sometimes but not others? This inconsistency is a classic sign of a dying battery.
- No Response: This is the most obvious sign – if your key fob doesn’t respond at all, there’s a good chance the battery is completely drained.
- Dashboard Warning: Some Land Rover models may display a “Low Key Fob Battery” warning on the dashboard when the battery is running low.
