  • [Corsa C 2000-2006] Issue with key or cars internal system!?!? Please help!

    First thing to note is that if your car battery is flat the alternator will not fully recharge it. You need to get it on a trickle charger to make sure the battery is restored to full capacity.

    Second thing is that the keys and the car work in sequence. If you press the key many times out of range of the car then they get out of sequence (I did this once whilst fishing, every time I stood up or sat down I was blipping the key fob but the car was miles away - then ti wouldn't work. But in the manual there is a sequence to re-sync the key to the car using the ignition switch. Or at least there used to be on some Vauxhalls. Do you have the manual for yours, or download one off the internet.

    If the engine management light is flashing that's usually a sign of the immobiliser being activated. The car should turn over but not fire as it cuts the fuel supply off.

    It is hard to say for sure without being able to inspect the car. You may be able to re-sync the key to the car yourself. But I am very wary of using jump leads on modern cars because it can cause issues if there's any kind of spike. I always use a separate starter pack these days. If you got a lead on wrong, or there was a voltage surge, it's possible that has caused the problem. In which case you'll need some professional assistance to check it.

    I'll see if I can find the sequence to sync keys and post a link.

      Actually when i got the car the buttons were pretty worn out and didnt do anything when you press them. And the keys had been sitting in my drawer. So maybe the problem actually startedvwhen the buttons stopped working. Could they have been out of sync all this time? Although the car did start on the first jump... maybe after the battery going dead again it could have lost all synchrony?
