Mercedes 220cdi estate,2x door lock buttons jump up and down repeatedly when i try to lock the car,any ideas?

Called roadside and they said it's the central locking system. Went to the parts department and they said it's the door latch. It has to be brought in to tell which is the actual problem. If it's a latch I can't tell which door it is and I don't really want to take it in and pay $200 for them to tell me.

Central locking on key not working, have replaced batteries and reset the key which did work, but key still not working. Can lock car from middle console and manually lock driver's door. Any ideas. Thanks

Turn ignition switch to position II. Turn ignition switch to position 0 and remove key. Within 1 minute: Press and hold key lock button. Press unlock button 5 times. Remote control should now operate system. If not: Repeat procedure.
Key remote control added or replaced. System malfunction.
Keys can only be programmed using diagnostic equipment.
NOTE this only works on ml up to 05

My 2003 mercedes kompressor C200 key is not working!

the key's are special order and they are fairly expensive. Test the voltage in your remote batteries. They should be 3 volts. These systems are very voltage senstive and require a good battery to operate properly. I'm assuming you have the original batteries in the remote now and it is 6 plus years old. These batteries generally last 3 years so it is definatly time if you have not replaced them yet!
