Mercedes GLE Key Fob Battery Issue

I have a GLE and know the frustration I had a similar issue with my key fob The range was terrible, and sometimes the car wouldn't detect the key Have you tried your spare key That might help isolate the problem

Thanks for the quick reply I didn't think about the spare key If it works, does that mean it's the fob battery Did you replace the battery yourself or use a service professional

Yes, if the spare works, it points to the low battery in your usual key fob I considered replacing it myself, but I worried about damage I took it to the workshop The battery replacement was inexpensive

Thanks for sharing Testing the spare key was helpful it works fine I agree the fob battery is the problem I'll visit the workshop The battery replacement costs about 37€ Thanks again
