Frequently Asked Questions
Do I need to program this module?
No. The main benefit of our service is that we program the module for you using your vehicle’s VIN before we ship it. It will arrive ready to be installed.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this part difficult to install?
For the 2005 Cobalt, the PCM is located in the engine compartment on the driver’s side. Installation typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. It is a manageable job for someone with basic mechanical skills. We always recommend consulting a repair manual for your specific vehicle.
What happens after I place my order?
After you purchase the 2005 Chevy Cobalt PCM, you will need to send us your VIN. We will then program the module and ship it to you. Instructions on how to provide your VIN will be sent after your order is confirmed.
Will this require a security relearn procedure?
In many GM vehicles of this era, a simple security relearn procedure (often called the “Passlock Relearn”) may be necessary after installation. This procedure is straightforward, requires no special tools, and typically involves turning the key in the ignition for set intervals. Instructions are widely available online or in your vehicle’s service manual.
