GM Immobilizer Reset: When and How to Program New Keys

GM immobilizer systems protect vehicles from theft but can be frustrating when you need to program new keys. This guide covers everything you need to know.

Understanding GM Immobilizer Systems

GM uses several immobilizer platforms: - **SPS2**: For Chevrolet, GMC, and Cadillac (2007-2020) - **WiTECH 2.0**: For newer Chevrolet and GMC (2020+) - **GDS2**: Dealer-level diagnostic software

Key Programming Process

1. Connect to vehicle via OBD2 scanner 2. Enter VIN and select service 3. Program new key(s) to the immobilizer module 4. Verify all keys work correctly

Common Issues

• **All keys lost**: Requires full immobilizer reset
• **Key not recognized**: May need module reprogramming
• **Multiple keys needed**: Can program up to 8 keys per session
