Hello and welcome to JustAnswer!

There are handful of things you could have going on depending on what system you have and the actual symptoms. If the issue is with factory security then it would start and die. Pressing the unlock button on the key fob would disarm the alarm, if it's a key immobilizer issue then simply inserting a correct key and turning it to the run position would validate the key as long as the system is functional.

What actual symptoms are you having?
