Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I need to know the year and model of your Mercedes in order to help you.
Ok, do the doors lock when using the button on the dash?
Ok, then the fault will usually be the remote control or the antenna for the remote. Have you replaced the batteries in the remote?
If both key worked previously I suspect you have a fault with the antenna for the remote. You can check the fuse for the antenna located in the trunk fuse box. Fuse #8 is for the antenna.
You need to check to see if it is blown or just try a new one.
Hi, I'm just following up with you on the Mercedes. Did you get this repaired?
