Yes. All-keys-lost origination is routine work for us. After we verify you own the vehicle with photo ID plus registration, title or insurance, we decode the key from the VIN, cut it in the van and program it to your BMW's immobiliser on-site.

No. We are a fully mobile Austin auto locksmith — the key machine, programming tools and blanks travel with the technician. We come to your driveway, office garage, H-E-B parking lot or roadside anywhere in Austin, TX, usually within 15–30 minutes.

Yes, on request we wipe every previously programmed key from the vehicle's memory so a lost or stolen BMW key cannot start your car again. This is included at no extra charge with any all-keys-lost job.

Yes. Once we confirm ownership with photo ID and registration, title or insurance, the VIN tells us the immobiliser generation, key frequency and blade profile, so we can prepare and cut the correct key and program it at your vehicle anywhere in the Austin, TX area.

An all-keys-lost BMW takes longer than adding a spare because there is no working key to originate from, and CAS4 or FEM/BDC cars need extra module work. Plan for a longer appointment than a straightforward spare; we give a realistic time window when we quote.

No. A dealership usually means towing the car in and waiting on a parts order. We carry the CAS3, CAS4, FEM and BDC equipment in the mobile unit, including secure-gateway vehicles, so the work is done where the car is parked.

BMW keys are encrypted to the car's immobiliser module rather than a simple transponder, so replacing one needs specialist equipment and, on newer cars, direct module work. That is why our BMW range is $269–$549 while common domestic keys start far lower.

Sometimes. It depends on the immobiliser generation and whether the fob is new or previously registered to another car. Send us the part number or a photo before you buy — on FEM/BDC cars a used fob is often not reusable, and we would rather tell you up front than program-test a key that cannot work.

Most often it is a weak fob battery or a Comfort Access antenna issue. We test the key and battery first; if the key itself has failed, we replace and program a new one on-site rather than recommending a new key you do not need.
