layton1837 Posted May 11, 2015 Share Posted May 11, 2015 Can anyone help on 2004 L322 Just had the batery replaced by main dealer. Now have problem programing key fobs.Have 2 Keys both original the problem i have is when i re program the first key it does prtograme and operates the central locking when i program the second key this accepts the program and again operates the central locking .But the first key loses its memory. If i reprogram the first key again it works but the second key loses its memory so that i can only have one key that is programed Quote Link to comment Share on other sites More sharing options...
pete3000 Posted May 12, 2015 Share Posted May 12, 2015 have you ever had both keys working as key1/key2? Sounds like the procedure to learn key 2 needs to be gone over with the dealer, as you are only learning key 1 then replacing key 1. Quote Link to comment Share on other sites More sharing options...
layton1837 Posted May 12, 2015 Author Share Posted May 12, 2015 Managed to sort out problem Both key are original. When programing the first key put key in ignition turn to first position then of straight away Hold down the open buttom and press the close button three times the doors will lock for the second key do not put it into the ignition but just hold the open button while pressing the closed button three times again the door should lock indicating that it is programed. My mistake was putting the second key into the ignition. Quote Link to comment Share on other sites More sharing options...
