Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Lost all keys to my BMW E46 / E39
- ✓Need a spare key cut and programmed for my E38
- ✓Car cranks but won't start, immobilizer / EWS fault
- ✓Dealer wants $400+ for one BMW key
- ✓Key turns but no start after EWS replacement
Won't fix:
- ✗CAS-based BMWs (E60/E90 and newer use CAS — see our CAS service)
- ✗Mechanical ignition lock cylinder / tumbler wear
- ✗Comfort-access / keyless-go fobs (EWS cars are blade-key only)
- ✗DME / engine faults unrelated to the immobilizer
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Ship your EWS module 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). IMPORTANT: if you need a key blade cut (all-keys-lost), also ship a door lock cylinder OR your key code — unlike CAS cars, the blade code can't be read from the EWS, so we need the lock to cut the blade. Return shipping is selected and paid at checkout — Standard $24.95 (3–5 days), UPS 2-Day $54.95, or UPS overnight $94.95.
What to include in your box
- The EWS module (and a working key if adding a key)
- A door lock cylinder OR your key code if you need the blade cut (EWS can't supply the code)
- Your order confirmation number
- VIN and the EWS part number from the label
- A note stating add-a-key vs. all-keys-lost, plus your name, return address and phone
