Water Damage: If your key fob has been exposed to water, the battery may not be the only issue. Open the fob and inspect for corrosion or damage.
Physical Damage: Cracks or breaks in the fob casing can affect functionality. In such cases, replacing the fob may be necessary.
Interference: Sometimes, other electronic devices can interfere with your key fob’s signal. If replacing the battery doesn’t solve the problem, consider checking for sources of interference.
