Something funny going on with the key

[cuckoo]

Hi i have a vr commodore there is something funny going on.

I press the button to unlock the doors no problem,i put the key in the ignition and it will not turn,untill i press the lock and then the unlock button again then the car will start.

i have to go through this sequence every time to start the car,has anyone had this problem or know what it could be.

Could this be a bcm on it's way out? or something wrong with the key head any help much apprecited

My VS is doing something simmilar. If I'm quick enough after unlocking the doors it will start, but if not I have to press unlock again.

No idea how to fix it undortunately.

do you have the original head units? i'm pretty sure it has something to do with the immobiliser.

head units as stereo? if so no aftermarket

that's really strange, because i've heard of it happening in several cases where thet immobiliser (which runs through the head unit) is not deactivated properley when you press the unlock key. so when you go to start it, the engine doesn't crank becuase the immobiliser is still active. so i have no idea if you have the genuine head unit.

I had the same problem when I had the original head unit in. No different at all when I put my aftermarked head unit in.

I had this problem once as well. When i replaced the remote on the key due to the rubber buttons worn through to the circuit board, it seemed to have fixed this problem as well. So i assumed it had something to do with the battery condition in the remote. Maybe you should consider replacing the remote on your key. I did mine through Mr Minute, cost approx $100.

id say its probably an ECU problem

I had this problem as well. It went away when I got a new head for the key.

I reckon that it is a good chance to be this.

I got mine through Ebay for $65 already programmed.
