Spare Car Key Duplication: what shapes the quote

Sometimes, when both vehicles share a compatible lock family and immobilizer system, most often two vehicles from the same manufacturer and a similar era. Sharing a keyway is not enough on its own: the two locks also need a bitting that satisfies both, or one vehicle's cylinders get rekeyed to match, and the transponder has to be capable of authorization on both immobilizers. Where they do not line up, the practical answer is two separate keys carried together on one ring.

Which key system the vehicle uses

A plain mechanical blade, a transponder key, a remote-head key and a proximity fob each call for different tools and different amounts of time, so identifying the system early shapes the whole quote before any cutting or programming starts.

Scheduling more than one vehicle together

Two vehicles booked into the same visit, such as a household's pair of cars, are generally more efficient to handle together than arranging two separate appointments on different days.

Condition of the working key

A clean, unworn original traces onto a blank without much fuss, while a thinned or damaged blade may need cutting to a factory code instead, which is a different process with its own materials.
