Just changed the batteries in the key of my C-Class 180 (2005) as it would not unlock the car but was OK starting the car. Now its the other way around, it opens the doors but not working when put in the ignition, any one any ideas?
The PCB in the early chrome key is the same as the all plastic key, and they were not supplied till 2007
Have you been up all day again? tut tut.
Sorry but No its not the same pcb.
PCB's are completely different for each. They cannot be swapped around, they wont fit.
The chip in the black key CAN be fitted to the older chrome key.
( but not the new chrome key)
