GM BCM RPO Feature Programming & US-Spec Lighting Service (2003-2020)
Stuck with a work-truck spec that skipped the options you actually wanted? One BCM tune enables them — RPO power locks and windows, steering-wheel controls, fog lamps, keyless entry, remote start, DRL / US-spec lighting and hyperflash delete.
Sending several modules? Add them all — one box, one return-shipping charge.

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Retrofitted power door locks (AU3) on an 03-07 Silverado/Sierra that need turning on in the BCM
- ✓Retrofitted power windows (A31) that move on the switch but are not coded in the BCM
- ✓Added UK3 steering-wheel audio controls on an 03-07 truck — BCM-only enable included
- ✓Colorado / Canyon / H3 with fog lamps fitted but T96 never enabled
- ✓Colorado / Canyon / H3 with the keyless receiver present but AU0 not coded
- ✓Re-imported Canadian/export truck with mandatory always-on DRL
- ✓Want DRL off, or DRL remapped to turn signals / fog lamps
- ✓Added factory-wired fog lamps that need enabling
- ✓LED turn signals hyperflashing / bulb-out warnings
- ✓Want factory remote start added, or longer remote-start run time
- ✓Added factory heated/cooled seats that need enabling
Won't fix:
- ✗Features whose physical wiring/hardware is not installed — we enable an option, we do not wire one in
- ✗Cannot enable AU3, A31, UK3, T96 or AU0 on a truck missing the motors, switches, lamps or receiver
- ✗Does not replace or clone a failed BCM — see our GM BCM Standalone Clone service
- ✗Post-2020 T1 trucks and the 2022.5+ refresh Silverado (different BCM)
- ✗Instrument-cluster indicators that need separate cluster programming
- ✗Anything requiring the cluster or radio module (separate services)
- ✗Never any odometer rollback — mileage is preserved as-is, always
Work-truck spec, or a Canadian import with always-on DRL?
Plenty of 2003-2007 Silverados, Sierras, Colorados and Canyons left the factory as base builds, then had power locks (AU3), power windows (A31), steering-wheel controls (UK3), fog lamps (T96) or keyless entry (AU0) added later — and the parts work mechanically but the BCM was never told the option exists. We enable those RPO codes on the bench for your VIN so the factory logic actually runs them. Same service handles the other direction on newer K2 trucks: Canadian-market GM trucks are built with mandatory daytime running lamps, and reflashing the BCM to "stock" just reloads the Canadian configuration, so it will not turn them off — we reconfigure US-spec headlamp/DRL behavior instead. The one hard limit either way: we enable options, we do not install hardware. If the motors, switches, lamps or receiver are not in the truck, no amount of programming will bring the feature to life, so we check your VIN and RPO sticker before you ship.
