You either need to resync the key to the car (instructions are in the manual) or you need a new key

To synchronise the system, do as follows:-


1. point transmitter in key to the door receiver.

2. press the key button briefly.

3. go to ignition switch and turn the key to position 2 (this must be done within 30 secs of above).

4. the infrared remote control is now operational again.

no i already try everything, like point to reciever and lock the doors inside the car, but nothing works i am going crazy because of this stupid original securiti system. i think that the answear to my proplem is that i have to order a new flip key from the benz factory in germany.???

There are two types of infra red systems on w124s, with different option codes. The procedure for synchronising is different. One is as described by kth286 above, and applies to option code 885. The other procedure, for option code 880, is: aim transmitter at drivers door LED. Press button for 5 seconds. Go round to passenger door, unlock with flip-out key.

Interesting! Some of the RCL systems seem to have an alarm & immobiliser and some don't. I wonder if that's the difference between the two option codes?
