TextHow Savana Key Security Changed Over 26 Years
First Generation (GMT600)
You turn this key in the ignition like any other key, but there is a Texas 4C transponder chip hidden inside the blade. GM used a VATS/PKM immobilizer system on these early vans, which means the resistor value and chip have to match perfectly or the engine will not start. Programming requires OBD-II tools and a PIN, so this is not a hardware store key.
Second Generation (GMT610)
GM combined the key and remote into one unit here, giving you a remote head key with an ID46 chip and three buttons. The Passlock II immobilizer runs the security side, and the good news is that on-board programming works if you already have two functioning keys. If you are down to one key or zero, we pull the PIN and program through the OBD port. Battery is a CR2032.
Third Generation (GMT610 Facelift)
GM upgraded the chip to a Texas 4D (ID47) and tightened the Passlock system. Still a remote head key with three buttons and a CR2032 battery, but on-board self-programming went away. Every new key needs OBD-II programming with a PIN, which means professional tools are required regardless of how many keys you have.
Fourth Generation (GMT610 Update)
The newest Savanas run a Texas Crypto 4D chip with Enhanced Passlock. Programming now requires both OBD-II access and GM server authentication on most configurations. That means your locksmith needs live credentials with GM's SPS system. We carry that access on every call, which is why we can handle these newer vans without a tow to the dealer.
Which Key Does Your Savana Use?
A metal key with a transponder chip inside. No buttons, no remote, no battery to worry about. Looks simple but the chip has to be programmed to your van's computer.
Your key and remote are one piece. Three buttons for lock, unlock, and panic. Uses a CR2032 battery you can swap yourself when the range starts dropping.
Looks nearly identical to the 2003-2014 key but uses a different chip inside. Same CR2032 battery, same three buttons. The difference is under the hood in the programming.
Same physical design as the prior generation, but the encrypted chip inside requires server-level authentication to program. Still uses a CR2032 battery.

Passlock II Sensor Failure
Security light on, engine refuses to start, key turns fine. The Passlock II sensor inside the ignition cylinder is failing, extremely common on 2003-2014 Savanas. We bypass or replace the sensor on-site so you aren't stuck waiting on a tow to Simi Valley.
Transponder Chip Recognition Loss
People blame the key. Real problem is usually the BCM losing memory of the key after a battery disconnect. On 1999-2010 Savanas we run a relearn through the OBD port and your existing key works again.
Remote Fob Battery Drain
We check battery and seal around the fob housing on a weak remote. On 2003-2025 Savanas the CR2032 drains fast because the case seal is poor from the factory. Fresh battery fixes most range issues; if not, contacts need cleaning or the fob needs replacing.
Immobilizer Module Corrosion
Fleet vans living on the road in Camarillo or Moorpark develop BCM corrosion from underhood moisture. When that happens the module won't accept new key programming. We extract the PIN, assess, and reprogram or replace on-site. Too far gone? We tell you first.
Can You Program a Savana Key Yourself?
No self-programming option. The VATS/PKM system requires professional OBD-II tools and a PIN to register a new transponder key.
If you have two working keys, you can program a third using GM's 10-minute relearn procedure. Insert the first key, turn to ON for 10 minutes, repeat with the second key, then the new key. If you only have one key or none, you need professional tools.
No on-board self-programming. The Texas 4D chip requires OBD-II programming with a security PIN, regardless of how many keys you have.
No self-programming. These vans require both OBD-II access and live GM server authentication. This is a professional-only job.

Did You Know?
Back in 1996, GM did something unusual with its full-size van platform. The GMC Savana and Chevrolet Express share their entire ignition and immobilizer system, making the key hardware identical across both brands for every generation since launch. If you have ever wondered why a Savana key looks exactly like an Express key, now you know.
