BMW Key Replacement Sydney – Smart Key Programming, Costs & Emergency Help
Losing a BMW key today is very different from losing a traditional car key.
Modern vehicles built by BMW use encrypted smart key systems connected directly to the immobiliser ECU. Every replacement key must be digitally programmed before the vehicle will start.
