Im sorry if this has been brought up before but I didnt find anything in a search.
The batteries went dead in the key, so I replaced them, of course the key still doesnt do anything so I need to re-sync it but dont have the owners manual so I have no idea how to do it.
Thanks in advance for instructions. Oh and its a 2002 ML320.

 

put key in ignition, turn two clicks...wait a few seconds..pull out key and with in 10 seconds hold down lock button push unlock button 5 times release both...push one once.( either one).

 

go near gas cap with remote . turn gas cap left 1 , right twice . and hit lock button

 

the gas cap thing is for the 1997, this is a 2002 ML.

 

same thing happend to me on 1998 ml 320 help!!!

 

I think i screwed up... my ml's alarm went off and i cant shut it off. its a 1998 ml 320

 

i reset my alarm but it only works for one time after. what could be the problem?
