Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your Cadillac SRX or another GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a car that refuses to start can all point to a failing Body Control Module (BCM). The BCM is the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. Dealerships will often quote you a fortune for a new module plus hours of programming fees. We offer a smarter, more affordable solution.
This is a comprehensive programming service for your 2013 SRX Body Control Module. Simply send us your original BCM, and we will clone all of its critical data—including VIN, mileage, and key information—onto this fully tested replacement unit. It will arrive back to you ready for a true plug-and-play installation, completely bypassing the need for expensive dealership tools or programming. Get your vehicle back to perfect working order without the headache.
A Technician’s Notebook
I recently had a 2013 Cadillac SRX in the bay that was driving its owner crazy. The symptoms were all over the place: the radio would cut out, the driver’s side window wouldn’t respond, and occasionally the vehicle wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery to no avail. After hooking up the scan tool, I saw multiple communication loss codes (U-codes) with various modules. This is a classic sign of a BCM failure. Instead of a costly new module and programming, we used this exact cloning service. The customer mailed in their module, we sent them back the programmed replacement, and the installation took less than 30 minutes. All the electrical gremlins were gone instantly. It’s a reliable fix that saves hundreds of dollars.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system light stays on or the vehicle won’t start.
- ✔ Dashboard warning lights appear randomly (e.g., ABS, Traction Control).
- ✔ Communication issues between modules, often triggering codes like U0140, U0155, or U0100.
- ✔ Wipers or horn activating on their own or not working at all.
- ✔ Problems with the keyless entry and remote start systems.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2013 Cadillac SRX, the BCM is typically located behind the dashboard on the driver’s side (LH dash). Its location in other compatible vehicles is listed below.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the original BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place.
- ✔ Install the Replacement: Mount the new, programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a click as they lock into place.
- ✔ Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- ✔ Test All Functions: Start the vehicle and test all body functions: windows, locks, lights, wipers, and radio to ensure everything is working correctly.
Important Post-Installation Notes
While this module is plug-and-play, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and will clear the light. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure correct brake light operation and traction control functionality. This is also performed with a scan tool.
Disclaimer: Always consult your vehicle’s factory service manual or a certified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
How does the mail-in cloning service work?
After you purchase, we will provide you with shipping instructions. You send us your original BCM. We then transfer all the essential data to the replacement module and ship it back to you, typically within 1-2 business days of receiving your original.
Will I need to get my keys reprogrammed?
No. Because we clone the data from your original module, the replacement BCM will recognize your existing keys. This is a major benefit that saves you time and money.
Where is the BCM on my 2013 Cadillac SRX?
The Body Control Module on a 2013 SRX is located on the left (driver’s) side of the vehicle, under the dashboard.
What if the airbag light comes on after I install it?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send my old BCM back after installation?
No, there is no core charge for this part. You only need to send us your original BCM for the initial programming service. You can keep it afterward.
