Why clone vs. new module
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- BMW won't start, dead CAS / no comfort access
- Replaced CAS and now I need it coded to the car
- Water-damaged or corroded CAS module
- CAS3 dot-matrix / no-crank intermittent fault
- Need a wholesale CAS clone for a customer car (locksmith)
Won't fix:
- EWS-era BMWs (pre-2005 — see our EWS service)
- FEM/BDC-only cars where the body controller is the issue
- Mechanical key blade cutting
- Engine/DME mechanical no-start unrelated to immobilizer
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Mail your original CAS (and donor module, if you have one) to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1009 Oakwood Ln # 120241, Arlington TX 76012 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box). No door lock needed — on CAS cars we read the key blade code straight from the module, so there's no lock cylinder to ship (unlike older EWS BMWs). Return shipping is selected and paid at checkout — Standard $29.95 (3–5 days), UPS 2-Day $54.95, or UPS overnight $94.95.
What to include in your box
- The original CAS module (and a donor CAS, if cloning)
- Your order confirmation number
- VIN and the CAS part number from the label
- A note: clone-to-donor vs. repair-original
- Your name, return address, and phone number
