Bypass the security feature on a 2000 Saturn sc2 series? Somebody drilled out my ignition. I replaced it but now it won't start just turns over but won't stay on?
You can't bypass the security system as it is integrated into the engine management and other systems.
The security system is generally disarmed by a coded transponder embedded in the key. When the key is inserted the transponder and the security system talk to each other and compare codes. If the codes match the engine will start.
I guess your new key either has no transponder or hasn't been coded. There is a possibility if your old key is held very close to ignition steering lock (before fitting the new key) then try to start with the new key and it might work. Sometimes once the system is disarmed a certain sequence can programme a new key - but that is something you will need to take further advice about.
