This service enables RPO code UK3 in your Body Control Module (BCM), activating steering wheel radio control functions on supported vehicles. It’s ideal if you’ve already installed an instrument cluster that supports UK3 and only need the BCM programmed.

Supported Vehicles

• 2003–2006 Chevrolet Silverado & GMC Sierra

• 2007 Chevrolet Silverado Classic & GMC Sierra Classic (Old Body Style only)

Service Includes

• Programming your BCM to activate UK3 (steering wheel radio control support)

• Return shipping of your programmed module

Requirements

• You must send in your original BCM

• Your instrument cluster must already support UK3 (either factory-equipped or previously upgraded)

• You must have a compatible steering wheel with UK3 radio control buttons installed

If your cluster does not yet support UK3, check out our BCM + Instrument Cluster UK3 Activation Service for a full solution.

FAQ

Q: Does my instrument cluster need to support UK3?
A: Yes. This service only programs the BCM. Your cluster must already support UK3 buttons (factory or upgraded).

Q: Can I use this service without a UK3 steering wheel?
A: No. The steering wheel must have compatible UK3 radio control buttons installed.

Q: Do I need to send my cluster too?
A: Only if your cluster does not yet support UK3. Otherwise, we only need the BCM.

Q: How long does the service take?
A: Once we receive your BCM, programming is typically completed and shipped back the next business day.

Q: Will this work on newer Silverado/Sierra models?
A: No. This service is specific to 2003–2007 Silverado and Sierra with the old body style for 2007 Classic models.

Q: What if my BCM is damaged?
A: Contact us before ordering. Some damaged BCMs may require repair or replacement before UK3 programming.
