I have an Infared remote unit with my car (car was imported from Europe, so it is a European Model).
The car came with Option Code 880 Locking/Closing System with Infared Remote and not the 885 Code Locking/Closing System with Infared Remote and Immobilizer (I am glad it does not have this).
In any case, I have one Infared/Key Remote for locking/unlocking and the spare set of keys are just manual/mechanical keys.
I looked in this forum in advance (so as not to waste anyones time) and other places on the web and I can not find a place to buy a spare Infared Remote. I can find plenty of places that just sell the empty IR Remote case, but none with the "IR guts".
Since I am not sure this (880 code) was an option on U.S. W124's (not 100% sure of this), I suspect my local MB dealer will have no idea if/where/how to get a spare key/remote.
1. if it's possible to get a spare IR Remote?
2. if it is possible to get a spare one, does anyone know how to sync it with my car (I have the procedure for resynching the existing IR Remote I have if I have to replace batteries and have them out > 1 minute)
