Ignition Lock Repair: reading the quote

In most cases, yes. Whether the cylinder is serviced in place or replaced outright, it is pinned to match the key you already carry wherever the vehicle's design allows it, rather than handing you a second key to keep track of. If the vehicle's own hardware makes that impossible, you are told before any work begins, not afterward.

Distance to where the vehicle is

Travel is part of every visit, and a vehicle parked across town takes a different amount of driving time to reach than one nearby, which factors into how the visit gets arranged.

Evidence of an earlier forced attempt

A lock that shows signs of having already been forced needs a full cylinder and housing replacement rather than a simple service, since the internal parts can no longer be trusted as they stand.

Age and history of the vehicle

An older vehicle may have hardware that is harder to source, or wear built up over many years of daily use, while a vehicle with a known repair history gives the locksmith a clearer starting point.
