Tired of Electrical Gremlins? Take Control of Your Regal Again.
As a technician with over two decades of experience under the hood, I’ve seen it all. A customer comes in with a car that seems possessed: the radio cuts out, the power windows have a mind of their own, the key fob works one minute and not the next, and a constellation of warning lights are on the dash. The culprit is often one of the most misunderstood components in a modern vehicle: the Body Control Module (BCM). Your 2014-2017 Buick Regal’s BCM is the central command for all non-engine electronics, and when it starts to fail, it can cause chaos. Dealerships will quote you a fortune for a new module plus hours of programming fees. We offer a better way.
This is not just a replacement part; it’s a complete, hassle-free solution. We provide a fully tested Body Control Module compatible with part number 13593776. The magic is in our professional cloning service. You simply send us your original BCM, and we transfer all its critical dataāincluding VIN, mileage, and key programmingāto the replacement unit. When you get it back, it’s a true plug-and-play installation. No expensive scan tools, no trips to the dealer, and no programming headaches. You get a reliable fix that restores your car’s functionality without the dealership price tag.
A Technician’s Notebook
I remember a 2015 LaCrosse (which uses this same BCM family) that had mechanics stumped for weeks. The car would randomly refuse to start, but only in the afternoons. The battery was new, the starter tested fine, and the ignition switch was replaced. After hours of tracing wires, I noticed the security light was faintly flickering during the no-start events. That pointed me straight to the BCM. The module had an internal fault that was temperature-sensitive, causing it to fail to recognize the key’s security chip when the cabin got warm. A cloned 2014-2017 Regal BCM from our stock solved the problem instantly, saving the customer from trading in a car they otherwise loved.
Is Your Regal Showing These BCM Failure Signs?
- ā Erratic or non-functional power windows, door locks, or interior lights.
- ā The key fob or remote start system works intermittently or not at all.
- ā Horn honking unexpectedly or the alarm system acting up.
- ā A ‘Service Theft Deterrent System’ message on the instrument cluster.
- ā Communication error codes, such as U0140, U0155, or other ‘U’ codes, stored in other modules.
- ā The vehicle won’t start, but the battery and starter are known to be good.
- ā Flickering dashboard lights or gauges behaving strangely.
Your Straightforward BCM Installation Guide
Installing your programmed BCM is a simple process. The BCM in the 2014-2017 Regal is typically located behind the driver’s side of the dashboard. While exact steps may vary slightly, here is a general guide:
- Safety First: Always disconnect the negative terminal from your car’s battery and wait a few minutes before beginning work on any electrical components.
- Locate the BCM: On the Regal, you’ll usually find the BCM to the left of the steering column, often behind the lower dash panel or kick panel. You may need to remove some trim pieces 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 Module: Seat your newly programmed BCM into the mounting bracket and reconnect all the electrical connectors, ensuring they click securely into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your electronics: windows, locks, lights, and radio. Everything should function as it did before.
Important Post-Installation Notes
Our cloning service makes this process as seamless as possible. However, in some vehicles, a couple of simple relearn procedures may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM. 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 your brake lights and traction control system function correctly.
Disclaimer: Always consult a factory service manual or a qualified professional if you are unsure about any step. These procedures can vary by specific vehicle model and options.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the unique data and transfer it to the replacement module. We then ship the plug-and-play replacement back to you, typically within 1-2 business days. Tracking information will be provided.
Do I need to send my keys with the module?
No, you do not need to send your keys. Because we are cloning your original module’s data, the replacement unit will already be programmed to recognize your existing keys.
Is there a core charge for this part?
No, there is no core charge. We only need your original module for the data transfer service. You can keep your old, non-functional module once the service is complete.
Will this fix my specific problem?
This service corrects issues directly caused by a failing BCM. If your vehicle has been properly diagnosed with a faulty Body Control Module, this is the most effective and economical solution. It will not fix problems related to other faulty components or wiring issues.
What if I still have an airbag light after installation?
In some cases, the airbag control module (SDM) needs to be re-synced with the BCM. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any competent repair shop with a professional-grade bidirectional scan tool.
