Illinois FAQ

Common questions from customers shipping from Illinois.

How long does shipping take from Illinois to your Arlington TX workshop?

Do you accept gm bcm rpo feature programming modules from Illinois?
Yes — we receive modules from Chicago, Aurora, Rockford, Naperville and the rest of Illinois regularly. With about 10.5 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Illinois.
Is there a gm bcm rpo feature programming shop in Chicago I should use instead?
Most Chicago shops don't keep the bench equipment for gm bcm rpo feature programming — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-region north — about 2 days each way.
Does Illinois vehicle inspection or emissions testing affect this service?
Illinois requires emissions testing in the Chicago and Metro-East St. Louis areas; downstate counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Illinois and federal requirements.
Can you add power locks (AU3) or power windows (A31) to an 03-07 Silverado or Sierra?
Yes, where the hardware is there. AU3 power door locks and A31 power windows are RPO options the BCM has to be told about, so a base truck that had the actuators, motors and switches added still behaves like a base truck until the BCM is reconfigured. Send your VIN and a photo of the RPO sticker and we confirm what your build can take before you ship.
Can you enable UK3 steering-wheel controls on an 03-07 truck?
Yes, including BCM-only jobs where the radio side is already handled and only the body control module needs the option turned on. The steering-wheel switches and the clockspring circuit have to be physically present — we enable the option, we do not install the switch pack.
