2004 E 55 Key not Unlocking and Locking from far away
Hey guys, I’m having an issue with the central locking on my 04 E 55.. The key only seems to unlock and lock the vehicle with the small square sensor on the driver door handle. My antenna amplifier seems to be working as I have FM radio signal, and everything else it controls is working except for the key.
I’ve also checked all the fuses and everything seems to be fine. I also disconnected the alarm siren to see if that was the issue but it didn’t seem to do anything (maybe I’m wrong, for disconnecting it)
Any help is appreciated
Thank you!
