Signs Your 2004 Corolla Key Fob Battery Needs Replacing
Before you start digging around for a new battery, let’s make sure that’s actually the problem. Here are the telltale signs of a dying key fob battery:
- Decreased Range: Is your car only responding to the key fob when you’re standing right next to it? This reduced range is a strong indicator that your battery is losing power.
- Inconsistent Functionality: Is your key fob working intermittently, sometimes locking and unlocking the doors but other times failing completely? This unpredictable behavior suggests your battery is on its last legs.
- Dashboard Warning Lights: Some 2004 Corolla models might display a warning message on the dashboard if your key fob battery is low.
