Expert Insight: The GM Passlock Security Relearn
A common headache when swapping a PCM on these 90s GM vehicles is the Passlock anti-theft system. An unprogrammed computer won’t recognize your key’s security signature, resulting in a no-start condition even with the new part. Because we pre-program this 1998-1999 Express 2500 PCM to your VIN, we handle the complex part. All that’s left for you is a simple ‘key-on, key-off’ relearn procedure that syncs the new module to your existing keys. It requires no special tools and is a crucial final step for a successful repair.
Don’t let a bad computer keep your trusty GM van or truck off the road. This is the most efficient and reliable way to solve your vehicle’s electronic brain teaser. By providing us with your VIN at checkout, you ensure that the 1998-1999 Express 2500 PCM you receive is ready to get your engine back in command.
