Mechanical and electronic parts
A blade may open the door while a separate transponder authorises the engine to start. Remote buttons are another function again. A complete replacement must match the specific system.
Mobile auto locksmith
Car key cutting and programming
Modern car keys often combine a precisely cut blade with a coded transponder or remote. Auto Key Works checks the vehicle and system before cutting and programming a compatible replacement.
How the service works
Why registration and year matter
Vehicles that look identical can use different key profiles or electronics. The registration, model and year help identify the likely procedure and suitable stock.
Mobile equipment at the vehicle
Supported cutting and programming can often be completed where the car is parked. Stable battery voltage and safe access may be needed during electronic procedures.
