Question type: Maintenance & Repair

So far, I have checked the chip resistance in the key. It is 4.75, so I had new
#11 pass key cut to code. The car still cranks, fires at times but will not run.
The " Theft system armed" light is still on. I tried resetting the alarm with the
trunk key unlocking the trunk and cycling the trunk lock, unlock 2 times to
reset alarm, but theft system alarm light won't go out. I bought a service
manual and I'm just about ready to diagnose the pass key system by the
manual. Theft deterrent modules are a problem with this model. Any ideas ?
