Car Key Replacement: reading the quote

Often, yes. A key that has been copied from copies or worn thin over the years lifts the wafers to the wrong heights, and a fresh blade cut to code restores the fit. If the wiggle continues with the new key, the wafers in the ignition cylinder have worn as well, and that cylinder can be overhauled so both the old and new keys turn cleanly. The locksmith checks the cylinder during the visit and tells you which it is.

Programming route the car allows

Some vehicles accept a new key through an on-board routine, most through the programming tool, and a few only through a dealer procedure. The route determines the time and the data involved, and the quote says which it is.

Year, make and model

The vehicle decides the blank, the chip and the programming route. A twenty-year-old sedan with a plain transponder key and a recent proximity-start model are different jobs, and the quote follows the VIN rather than a flat figure.

Security data for the vehicle

Some cars give up their programming PIN through the tool; others require the code to be retrieved from manufacturer secure data, which involves a registered request. That step is quoted when the VIN shows it applies.
