That synch'ing feeling...
Ok, so I have obtained and installed an MB-sourced, and expensive, NS door lock barrel, with a tailgate one on order also. Both the original locks had seized through non-use.
I expected that I would then achieve a straightforward synch of the second, NEW, IR key I also sourced from MB last year, which I not been able to synch before owing to the seized locks.
I found this in a helpful post from 2005:
"There are two types of infra-red systems on w124s, with different option codes.
The procedure for synchronising is different.
To synchronise the system, do as follows:
One procedure, for option code 885, is:
1. Point transmitter in key-fob 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).
The other procedure, for option code 880, is:
1. Aim transmitter at driver’s door LED.
2. Press button for 5 seconds.
3. Go round to passenger door, unlock with flip-out key.
4. The infrared remote control is now operational again."
My car is code 880 for the IR option. I think the distinction between the two is that 885 links to an MB-fitted alarm and also has the console mounted central locking switch; hence the need to synch through the ignition. 880 has neither of those.
So...
My new key is working and sends its little red bleep signal. I followed the procedure above for 880, and have tried several times, but the key will not synch. I also, btw, tried the 885 approach, for what it was worth.
Any ideas anyone? If not, I think the answer maybe to wait for the tailgate lock, because there the physical lock is connected directly to an IR receiver - maybe that will work?
