Overview
Lost BMW Keys? We Make Them On Site.
Nassau's Best Locksmith And Car Keys replaces and programs BMW keys without a trip to the dealership. Whether you need a second key, a replacement after a loss, a new remote or a full all-keys-lost job, our van carries the blanks, shells and programming hardware for BMW platforms and we finish at your vehicle.
European immobilizer systems are the hardest keys on the road. Most locksmiths and even many dealers send these cars out. We invest in factory-level tooling — BMW BDC/FEM bench coding, Mercedes FBS4 all-keys-lost, VAG MQB49 IMMO data reading, Volvo CEM and Land Rover KVM programming — so your car is finished at the curb instead of towed.
BMW key service is determined by the immobilizer module. Many E-series vehicles use CAS, while F- and G-series vehicles may use FEM or BDC. Some keys can be added through the diagnostic port; others require protected module-data work away from the vehicle connector.
We read the vehicle information, select the correct key style and frequency, safely create the key and synchronize it with the car. We then verify starting, remote functions, Comfort Access when equipped and the emergency blade.
BMW models we service
3 Series • 5 Series • 7 Series • X3 • X5 • X7 • M3 • i4 — plus older and current model years not listed here.
What affects the price of a BMW key
Three things: the key type (blade, flip, remote head or proximity smart key), the immobilizer generation of your model year, and whether we still have a working key to clone from. All-keys-lost costs more because the immobilizer data has to be read and a fresh key written. We quote firmly on the phone once we know year, model and VIN.
