Frequently Asked Questions
How does the programming process work?
It’s simple. After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use that number to load the correct, updated GM software onto the module. It arrives at your door ready to install, with no extra steps needed.
Do I need to perform any procedures after installation?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or Passlock relearn), which can typically be completed without special tools. Instructions are widely available online for your specific model.
Is this the correct PCM for my car?
This 1996 GM PCM 16211539 fits a wide range of 1996 GM models. To ensure a perfect match, please verify that your original part has one of the compatible service numbers (16211539, 88963800, or 16231853) and check the fitment list on this page. Providing your VIN for programming is the final confirmation of compatibility.
What information do you need from me?
We only require your vehicle’s 17-digit Vehicle Identification Number (VIN). You can find this on your driver’s side dashboard (visible through the windshield), on the sticker in your door jamb, or on your vehicle’s registration and insurance documents.
What if my original part number isn’t listed?
If your part number is different, please contact us before ordering. GM used many different part numbers across their vehicle lines, and our experts can help verify compatibility to ensure you receive the correct module for your vehicle.
