hi,i have been trying to find a alarm fob for my 2000 626.have tryed 3 off ebay but without success,but what works on mine to gain access to the cars system is 1 sit in drivers seat with the door open 2 insert the ignition key and turn to the on postion (do this 3 times in straight concession) 3close and open the door 3 times (with the door being open on the last go)locks will lock and unlock to tell you that you are into the cars system 4press any button on your fob 2 times (doors will lock and unlock)if you only have 1 fob do this 3 times if you have 2 do i fob twice and if you have 3 do all 3.close door doors should lock and unlock try your fob.hope this helps but do it at your own risk (it says that on the sheet i have )
