    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?:(

    If it has been dropped the transponder coil may have broken loose and now fallen off

    It does not make much difference to the PCB inside

    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. :cool:

    Sorry but No its not the same pcb. :rolleyes:
    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)

    It is as near as dam it the same for the purpose of this thread and post, I did not say anywhere that they were interchangeable.
