hi yes i can lock and unlock the car with the infa red key but you know when you unlock the doors the central locking knob pops up and in one or two seconds the indicators flash twice and the light on the door handle goes to green mine does all that but the light goes green-red flashing together
Ok, sounds like an alarm/imobiliser fault rather than a key problem.
Maybe worth trying to search the forum for any similar problems and if nothing it may be a wait for a more experienced person than me to direct you to the fault.
It seems odd that you can not overide the imob even when opening with the key ?? Not sure if that is how its meant to be or if its just my two??
Just hope its not all coded to the car meaning you need to get the MB dealer to code a new unit for you! ( my scorpio had a problem like that and the whole lot needed changing locks and all)
all the best and good luck,
Try changing the batteries in the remote first though the key will operate the central locking does,nt actually mean its operating the alarm system, normally when the red & green lights flash it is indicating they are flat/going flat.
As above, Red and green flashing TOGETHER, means batteries are low so the imobeliser hasn’t disarmed so you can’t start the car.
Red and green flashing ALTERNITAVLEY when you put the key in ignition and turn it to position 2 means the imobeliser hasn’t disarmed because your battries are low Or installed incorrectly Or your key fob isn’t transmitting a signal... I think.
