remote central locking

hello ,does anyone have any idea why both my vectra keys have stopped
working my central locking , both have brand new batterys , cant
understand it , any ideas ..........thanks Mark

 

Try putting ignition on and pressing the lock button on each fob in turn.

 

Have you tried 're-syncing' the keys with the ignition. Theres usually
something in the handbook about it. I know how to do it for an Astra but not
a vectra.

As mentioned, you almost certainly just need to re-program them --
they 'lose' the program if they're operated a few times outside the
range of the car - no idea why but it's what the handbook says. Just
sit in the car, turn on the ignition and operate each unit to
lock/unlock the doors - should work. If not then it must be a faulty
sensor in the car - probably expensive.

 

It's because they shift codes to fool "code grabbers" They need to "talk"
to each other
