Yep, series 2...and the key it came with had keyless entry on it...Since installing the alarm I've just been using the nismo key, and the remote to open doors obviously...
I played around with a few wires in there, and it seemed to work....then died shortly after.
Just a suspicion/thought, the passenger door lock button on the drivers side window controls, I remember when the installer did the alarm, that button no longer locked/unlocked the passenger door anymore....now that the remote is failing to lock/unlock the doors, that button is working again....
When I pulled the trim off, I obviously had to disconnect the plug that controls that button and the wipers etc...The doors didn't lock from the remote until I reconnected that plug...Is there a chance its got something to do with that? If I was to cut the wire that controls that door lock button, any chance that would solve the issue?
