If your key fob isn’t working there are a few things you’ll want to check. Firstly, move closer to your car. Your vehicle may simply be out of range, and when there are obstacles in the way such as walls, trees, or other vehicles, your range can be reduced significantly.

If range isn’t the issue, then you will want to ensure that your car can still be operated normally. You could have a dead battery or some fault in your car. If that’s not the issue, then it could just be your battery in your key fob. Your resident Mercedes-Benz dealer, perhaps Mercedes-Benz of Scottsdale, can take care of that for you or you can refer to your manual to replace it yourself.

If you can lock and unlock your doors, then you should review your user manual.
