What it means
The key fob battery is low and its buttons or keyless functions may become unreliable. Amber usually means replace it soon; the symbol, colour, and remaining warning time vary by manufacturer.
What the symbol looks like: A key fob outline beside a low battery symbol, or a key with a warning mark, commonly indicates a weak fob battery.
Why it comes on
- The fob coin-cell battery is nearing the end of its life
- Frequent use of remote buttons
- A battery that was fitted incorrectly or is the wrong type
- A faulty or damaged key fob
What to do
- Check the owner's manual for the correct battery type and replacement instructions.
- Replace the fob battery soon, observing its polarity.
- Keep the spare key available in case the fob stops working.
- Use the manual's emergency key or starting method if needed.
- If a new battery does not clear the warning, have the key checked.
Can I keep driving?
You can usually keep driving; the warning concerns the key fob, not vehicle control. Replace the battery soon because the vehicle may not recognise the key or allow a later restart.
Symbols and colours differ between makes and models. Your owner’s manual shows the exact lights of your car.
