What determines the estimate?
A working key often makes duplication simpler than all-keys-lost service.
Laser-cut and high-security blades require the correct cutting method.
Smart and transponder keys generally need vehicle-specific programming.
Why QuoteMyKey uses a range: key hardware and programming can change even within one make or model family. The engine matches the vehicle to the best available platform data, then keeps the estimate inside known market references when available.
