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
