Tired of Chasing Electrical Gremlins in Your GM Truck?
If your 2000 Suburban, Tahoe, or Yukon is acting possessed—with flickering lights, power windows and locks with a mind of their own, or a security light that prevents it from starting—you’re not alone. After 20+ years in the shop, I’ve seen these exact issues hundreds of times. The culprit is almost always a failing Body Control Module (BCM), the central command center for your truck’s body electronics. Instead of a costly trip to the dealership for a new module and programming, our professional cloning service provides a simple, effective, and permanent solution.
We take the vital data from your original BCM and transfer it directly onto this replacement unit. This means your new BCM arrives at your door ready to install, with no additional programming required. It will recognize your existing keys and vehicle-specific options, making the process as close to plug-and-play as possible. This is the smart fix for both seasoned mechanics and determined DIYers.
Case Study: A Tricky Diagnosis
A customer brought in a 2000 Yukon that would intermittently refuse to start. The security light was flashing, a classic sign of a Passlock system failure. They had already replaced the ignition switch and lock cylinder with no luck. After connecting my scan tool, I noticed communication with the BCM was dropping out. We performed our cloning service on a replacement BCM. Once installed, the security system functioned perfectly, and the no-start condition was completely resolved. It saved the customer from an expensive dealership visit and got their reliable truck back on the road.
Is Your Truck Showing These Symptoms?
- ✔ The security or anti-theft light is on, causing a no-start or crank-no-start condition.
- ✔ Power windows, door locks, or interior lights operate erratically or not at all.
- ✔ The horn honks unexpectedly or the alarm system randomly activates.
- ✔ Instrument cluster gauges behave strangely or warning lights stay on.
- ✔ Communication errors with the BCM are present (Common DTCs: U1000, B2960).
- ✔ The radio or other accessories don’t turn off after removing the key.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the Module: The BCM is typically found under the driver’s side of the dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount the replacement BCM and securely plug in all the electrical connectors. You’ll hear a click when they are properly seated.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, and radio—to ensure proper operation.
Important Post-Installation Steps
In some cases, your vehicle may require a simple relearn procedure after the new BCM is installed. These are straightforward tasks for a shop with a capable scan tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the two modules.
- Brake Pedal Position Relearn: A brake pedal sensor recalibration might be necessary to ensure your brake lights and traction control system function correctly.
Our cloning service for the 2000 Suburban 1500 BCM is designed to be the most efficient repair path. We handle the complex programming so you can focus on the simple installation. Your original module will always be returned to you along with the programmed replacement unit.

How does the cloning service work?
How does the cloning service work?
After you place your order, you’ll ship your original BCM to us. We use specialized equipment to extract the vehicle-specific data (like VIN, key information, and options) and flash it onto the replacement module. We then ship both your original and the ready-to-install replacement back to you.
Do I need to send you my VIN?
No. For our cloning service, all we need is your original module. The VIN and all other necessary data are contained within it, ensuring a perfect data match.
Will my original keys work with this BCM?
Yes! Because we are cloning your original module’s data, the replacement BCM will recognize your existing keys. You will not need to have new keys cut or programmed.
What if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this a difficult part to replace myself?
The physical replacement is straightforward for most DIYers with basic tools. It involves removing a lower dash panel and unplugging a few connectors. The difficult part is the programming, which our cloning service handles for you before the part even ships.
