My "Service Theft deterrent system"
I have tried taking the battery cable for 15
min and still wont work. And i also tried
unlocking and locking doors with key fobb
and manually.. What is some other options?
This is a very common problem on GM vehicles. The security system is notoriously known to fail. Basically when you insert your key, the system checks for a certain signal. If the system cannot get the correct signal from the key, it assumes the key is incorrect or you are attempting to hotwire it. The system then goes into SECURITY lockout mode. (prevents vehicle theft) This will either turn off the starter, or the fuel injectors. This has been happening with GM's for a very long time. There are ways to bypass this now. Google Newrockies inc. They make a bypass for this.
