An Expert’s Note on GM Security Systems
“Back in the late 90s, GM’s Passlock/VATS security system was a major hurdle for repairs. A new, unprogrammed module would leave the vehicle immobilized. That’s why our VIN programming service is so critical for these specific vehicles. By flashing the computer to your VIN ahead of time, we handle the most complex part of the job. This allows a knowledgeable DIYer or any professional mechanic to complete the installation without needing specialized GM diagnostic equipment. It turns a potential headache into a manageable weekend repair.”
Take control of your repair and restore your vehicle’s performance and reliability.

This Programmed 9355699 PCM is your key to solving complex electronic issues and getting your trusted GM back in service.
