Hi all,
Yesterday I replaced an alternator and I have disconnected battery to do so. When finished and connected battery back again, central door locking stopped operating with key fob, I am unable to open boot and alarm won't arm up).
I can open driver's door with key (only driver's door opens, other syat shut) and I can open all doors with button on driver's door - all doors open and close no problem.
I have checked all fuses. I thought that key fob may need re-programming but system did not unlock/lock vehicle after four steps, it did not activate programming mode. Same with spare key. I have disconnected battery once again (to reset system) and tried again, no joy.
I had to go to shop and when I got there all of the sudden I could lock the door, open boot and activate the alarm with key fob. When got back home I have had to disconnect battery again, and the problem came back... I have tried disconnecting battery again, etc. nothing. So I left battery disconnected again and wanted to get back to it the next day, but I had to drive to my parents so I connected all again. When got to my parents (5 min drive) locking door system started working again... I have checked it many times, yesterday night and when I got up, to open and close door remotely and it worked fine, alarm was on and indicators were flashing.
But... only one key worked, the spare one (?) the one I have used all the time would not work at all.
And it worked till this morning when I opened car, got inside, put key in and I could hear door locks moving in all door (although all door were opened) and it stopped wotking again.
So summing up:
- I have replaced alternator and to do so I had to disconnect battery
- I can't open lock door, open boot and activate alarm
- I can open driver's door with key (all other door stay closed)
- I can open/close all door with button inside car (driver's door panel)
- system not responding when trying to program keys, looks like it does not go into pogramming mode
- it happened twice after 5 min drive that problem got fixed itself
- this morning when I opened car and put key into ignition I could hear door locks moving and remote door locking system stopped working...no alarm etc.
Could you tell me what I should be looking for please?
Thank you
