Sounds like they installed the wrong BCM (Body Control Module). There were different BCMs for cars equipped with different features. Sounds like you got one for a car with keyless entry but no alarm. HTH. -Jim

Yes, that's correct. If your Trans Am is like my '00 Grand Prix there were 3 different BCMs. They're referred to as Type 2, Type 3, and Type 4. You want Type 4 (with content theft deterrent). Type 3 does not have the theft deterrent option. Type 4 does. HTH. -Jim
