Losing the last key to a car leaves two options. The dealer route means a tow, a service appointment and sometimes an ordered part before anybody touches the vehicle. The other route brings the equipment to wherever the car happens to be sitting and has you driving within the hour. Keys are cut and programmed on the spot for Toyota, Honda, Subaru, Nissan, Hyundai, Kia, Ford, Chevrolet, Mazda and most European makes, in a Sun Valley Mall row, at either BART lot, in a student space at Diablo Valley College, in a carport behind a fourplex on Detroit Avenue, or in one of those wide tract driveways off Ygnacio Valley Road where the car has not moved all week.
Two separate things have to be made before the car will drive: a blade and a chip. The blade is cut to a code read off the door lock or pulled out of the vehicle itself, which is precisely why an empty key ring does not mean a tow truck. The chip is the half that catches people out. Cut a blade perfectly, skip the immobilizer, and the car will turn over and then die about a second after it fires, so the transponder is written before the door is shut again. On models that support it, the keys that disappeared are removed from the vehicle memory during that same session, which means one turning up in a coat pocket next spring is a piece of metal and nothing more. Proximity fobs for push-button cars are covered on their own page under fob programming. Identification and registration get checked at the start, not once a key is in your hand.
Car key replacement is $149 to $379 per key, and the $89 service call is inside the figure. A plain transponder key for a common Japanese or domestic car is $149. Remote-head keys, rolling-code systems on newer vehicles, and all-keys-lost work where the immobilizer module has to be read take it to $379. An evening arrival puts that first key at $189 and an overnight one at $224, both already sitting inside the number named on the call. A key snapped off in a lock is extracted as part of the same visit rather than appearing as an extra line.
You call and give the street or the lot and what the car is doing: year, make, model, where it is parked, and whether any working key still exists, because that answer shapes the method more than the badge does. The figure is said on the call. The van leaves Todos Santos Plaza, and a text names the technician and gives a thirty-minute window; sixteen to thirty-one minutes covers Concord, with the college and North Concord at the long end. Ownership, blade, chip, erasure of the lost keys, then both front doors, the trunk and a start with the engine actually running. The receipt carries the figure you were given and arrives while you are sitting in the driver seat.
“Came up the escalator at North Concord to find my keys sitting in the door pocket and the car locked. $118 on the call. Twenty-three minutes and the van was in the park-and-ride row. He worked the top corner of the frame and there is not a scuff on the paint or the weather seal, which I checked twice because the car is new enough that I would have noticed. Tapped my card in the lot and the receipt was in my email before I got on the freeway.”
Every job is priced from the list below. Most of this city was fitted with the same few locks between 1955 and 1968, so the street usually settles the figure on the call, and the receipt carries it unchanged.

FAQ
Car Key Replacement: quick answers
The dealership wants the car towed in and a week of waiting. Is there another route?+
It is the only way a dealer can do it, because their programming equipment never leaves the building, so the vehicle has to be brought to them and then wait its turn in the schedule. Mobile work reverses that. The blade is cut and the transponder written at the curb, in one visit, and a single per-key figure holds the trip, the labor and the key itself. Most people who call in the morning are driving the car again that afternoon.
All the keys are gone and the car is in the carport behind my building, with the gate remote on the same ring.+
Text over the address and the space number, and plan to let the technician in through the pedestrian gate yourself, since the remote vanished along with everything else. None of that alters the work: a code comes off the door lock, a blade is cut to match, the transponder is written and the missing keys are struck out of the vehicle memory. Gate remotes can often be replaced in the same visit as well, and if yours can, the figure for it is agreed before anything is ordered.
If somebody finds the key I lost, can they still start the car?+
Not once the erasure has been done, and that is the part of this job worth caring about most. Most vehicles hold a list of authorized transponders, and rewriting that list drops the missing ones out of it, so the old key becomes a piece of metal that fits the lock and starts nothing. A handful of older models cannot be cleared that way, and where yours is one of them you are told on the call, along with what replacing the cylinder would cost if you want the mechanical side closed off too.
