BMW Key Questions
What does it cost to replace a BMW key in Westchester?
Standard transponder and remote head keys (EWS and CAS system cars, roughly 1995 to 2013) run $199 to $299 with us. Comfort Access smart keys for F-series and G-series cars (2013 and later) start at $350 to $499. Dealer pricing for the same keys runs $400 to $700 or more, not counting labor. Call us with your year and model and we quote you exactly on the phone.
Can you program BMW Comfort Access on-site?
Yes. Comfort Access keys for the F-series (F30, F10, F15) and G-series (G20, G30, G05) use the FEM or BDC system and require specialized programming equipment. We carry that equipment in the vehicle. No tow to the dealer, no appointment.
I lost all copies of my BMW key. Can you still make one?
Yes. Lost-all-keys programming is something we do regularly for BMW owners. It takes longer than adding a spare and costs more because the system must be cleared and reset. Call us with your VIN and we walk you through the process.
How long does BMW key programming take on-site?
For standard CAS-system cars, typically 30 to 45 minutes at your location. FEM and BDC cars (2013 and later) can take 45 to 75 minutes depending on the exact model and whether all prior keys are being cleared.
Do you come to me, or do I need to go somewhere?
We come to you, anywhere in Westchester County. Home, office, parking garage, roadside, Metro-North commuter lot. You tell us where the car is and we drive to you.
