Problem Remote Key E320 1997
My remote key doesn't work.
I press button and not lock / unlock doors, but the key blinking Red Light comes on.
P.S. It comes up after I changed Radio Stereo. I do not know if it's relevant to that.
When I press the remote key, the doors won't lock/unlock, but the red light on the remote key was blinking while I press the lock/unlock button, and the left and right light was blinking.
