I locked my car using my central locking key. I cannot unlock the car because the remote is not working after locked the car. The alarm sound is coming up if I try to open the driver door by using the key. The crucial problem is the car not starting in this condition. So I disconnected the wires from the battery which is connected with alarm but still the alarm is working because all are directly connected to ECU of the car. I tried with the new replaced battery in remote but it doesn't work. My doubt is that if I change the new key and program for the new key, does it work? Why I am asking is that it is already in lock if the is unlock position then the new key will work. More over if I disconnect the main battery for thirty minutes and reconnect it, is the ECU reset? Can I start the car after that? My car is listed above VZ model.

Hi and thanks for using 2CarPros.

This vehicle is not offered in the US, but I know it was manufactured by Holden (GM) in Australia in 2004. Based on that, I am going to do my best at helping. Here is the relearn process for key-less entry issues, such as you are experiencing. These are based on the Pontiac G8 (2004) which is basically the same vehicle as you have.

In order to correct a key fob that is out-of-sequence, follow these steps:

1. While seated in the vehicle, press and hold the unlock button on the key fob.

2. While still pressing the unlock key on the fob, insert the ignition key into the ignition switch and turn the key to the ON position.

3. Once the Driver Information Center (DIC) cycles, release the unlock button.

4. Turn the key to the OFF position and remove the key.

The key fob should now operate both doors and security.

Let me know if this helps.

Take care,
Joe
