Spare Car Key Duplication: getting ready

Two coworkers share one delivery van and one key between them, trading it at the start and end of every shift in a parking lot. A missed handoff leaves someone standing beside a locked van with nowhere else to be.

Worth answering before the call

Does the key have buttons, a chip, or neither? Is there more than one vehicle you would like keyed the same way? Where is the vehicle usually parked?

Does the new key need to be identical to the original?

Not necessarily. Most households want a spare that behaves exactly like the first key, and that is the default. Some prefer a simpler version for a particular driver, such as a mechanical key without remote buttons for a valet or a young driver. Either choice is a programming decision made at the start of the visit, and the resulting key is fully recognized by the vehicle either way.

Can one key work for two vehicles?

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.
