Hi there I spent 5 hours on a similar issue trying to do a simple fix on the rear lights for a friend and in advertantly tripped the Security imobilser by removing the fuses for the box. It turns out that there was a factory upgrade to the security system which repositions the reset button. please have a look under the hood (USA)/ bonnet (UK) latch bracket. The factory mod to the security system months the reset button at the rear bottom of the bracket. Procedure is them as per the cars101 info previously suggested. I.e. Open drivers door - hold button for 15 seconds, etc. Hope that helps.
