Hi all - I have a 2007 MCS (just purchased as a runabout to get and forth to work). I've changed the batteries in both remotes, but only the lock button seems to work (both remotes). If I unlock with the key, both doors and the boot unlock correctly, and everything functions normally from the dash switch. The downside is that every time I open the doors with the key, the alarm goes off! The neighbours love me when I'm leaving for work at 6am, so I've had to temporarily pull the siren fuse so it doesn't look like I'm trying to steal it. Any help would be greatly appreciated.
