how do I reset the security system on my 98'? The fob opens the doors but, the security systems stays on and will not let car start. anyone have any answers, thanks

 

Does the alarm activate when the door is opened? If not, have you tried your spare key to see if it works?

 

I can turn the alarm off with the key fob, I have tried both spare keys in both doors, I have disconnected the battery and even charged it, then resetting the fob, nothing seems to work, thanks for the reply[] does anyone know how to turn the VATS system off?

 

So, you did this, right?

To reset a keyless entry remote, stand in range of the car and hold the "Lock" and "Unlock" buttons for 10 to 12 seconds. If it resets, the horn will sound and the remote will work again. If this does not work, follow the procedures below:

1) Turn on the ignition, but don't start the engine.
2) Press "Reset" button in order to clear any IPC display warning messages.
3) Press and release the "Options" button on the Driver Information Center (DIC) to scroll through the display options until the IPC display is blank.
4) Press and hold the DIC "Reset" button for 3 seconds until the FOB TRAINING message appears.
5) Press "Reset" once again and it will ask you to hold the "Lock" and "Unlock" buttons on the first remote. (Corresponds to Memory button one, if you have the memory option)
6) The horn will sound, indicating the remote frequency has been learned.
7) Repeat the process for the next remote. You can have up to 3 remotes per car
