From the shop
The SKIM module on '03–'07 Cadillac CTS and SRX controls the immobilizer circuit — when it fails, the car cranks but won't start, and the security light stays on. This is an OEM unit that will require re-programming to your VIN by a dealer or locksmith before it'll recognize your key. That step takes about 20 minutes and is the standard process for any SKIM swap on these models. Ships Mon–Fri before 3pm EST. — Hubes
