Inspecting Key Fob/Door Locks

First things first, check your key fob and door locks. Are they damaged? Are they working properly? If not, you might need to get them repaired or replaced.

Trying Spare Key

Have you got a spare key? Try it. Sometimes, the problem is with the key rather than the car. If the spare key works, you’ve found your culprit.

Replacing Dead Battery

Check your car’s battery. Is it low? If yes, it’s time for a battery boost. Replace the dead battery and see if the symbol disappears.

Attempting to Start the Car

Try starting your car. Does it start? If not, the problem might be with the immobilizer system. You should get it checked by a mechanic.

Using a Physical Key

Checking Fuse

Check the fuse. Is it blown? If yes, replace it. A blown fuse can trigger the ‘car-with-key’ symbol.
