Instructions for GM key programming with SPS2 (Techline)

GM key programming takes place when the GM vehicle has just been replaced with a new key, at which point programming is needed to relearn the key for the vehicle. From there, you can use the new key. You can relearn the key using mechanical steps or use software to perform this process. In this article, Eurocartool will show you how to program the key using Techline software.

GM key programming and Device required

The process of GM key programming using software needs to be performed by technicians with experience working with software and professional equipment. Key programming will require accompanying software and equipment. To be able to program GM keys, you will need to prepare the following software and equipment:

  • Techline software
  • Connection device specifically for GM MDI2 or Tech 2 Scanner vehicles (however you can also use a number of other devices such as MDI, Autel, VCM 2, VCX SE, VCX NANO,…)
  • Computer: Configuration i5 generation 3, Ram 4GB or more; Hard drive SSD256 or higher, Windows 10 or 11
  • GM ONLINE LOGIN account (if you do not have an account, please contact us for advice)

With your GM ONLINE LOGIN Account you can also perform advanced functions such as GM key programming, key fobs, replacing ECU engine boxes, TCM boxes and other control boxes…

What is Service Programming System (SPS2)?

SPS 2 (Service programming system 2) is an application that allows access to GM data via the internet to program or reprogram all vehicle modules.
It works by accessing vehicle systems by reading VIN information
from the vehicle, thereby extracting accurate update data from the available data files of the SPS application, then proceeding to update the memory and possibly reprogram the vehicle’s data.

Instructions for GM SPS2 key programming

In the implementation instructions, Eurocartool will guide you in two ways: using SPS2 and performing mechanically. Depending on your specific wishes and purposes, you can use different methods. However, using SPS2 requires skills and experience as well as professional software and equipment to perform. Below are 2 ways that you can refer to GM SPS2 programming.

How to use SPS 2 programming key for GM?

Below are the steps to help you quickly GM key programming with software.
Step 1: Insert the key into the car
Step 2: Connect the MDI2 device and software to the vehicle
Step 3: Open Tech2win software
Step 4: Login account
Step 5: Select SPS2 (Service programming system)
Step 6: Enter the vehicle type and model

Instructions for programming GM mechanical keys

In addition to Techline connect SPS2, you can completely relearn the key by following these steps:
Step 1: Sit in the driver’s seat and close all car doors
Step 2: Plug the car key into the ignition system
Step 3: Press and hold the car unlock button
Step 4: Turn the ignition key twice while holding the unlock button (no need to start the car)
Step 5: Release the door unlock button to enter the vehicle’s programming mode
Step 6: Press and hold both lock and unlock buttons on the smart key for 15 seconds.
Step 7: Turn the key to run mode to turn off the vehicle’s programming mode

You can perform the mechanical operations first, but the learning process is basically just to recognize the new key. If you want to reprogram the memory, you need to use Techline connect and SPS2.
