- The call
- The only key to the car went into the lake with the kayak. Now the car sits locked in the driveway with a full tank, and there is no spare in the house, in a coat pocket or anywhere else.

The car is yours now, but somebody else still holds a key to it. Adding another key is not enough; you want the old ones to stop working the vehicle so the question is settled for good.
It helps to think of a car key as several parts sharing one case. The metal blade is the mechanical part; it opens the doors and, on older cars, turns the ignition. The transponder is a small chip with no battery that answers the immobilizer when the key is near the ignition; without the right answer the engine refuses to run. The remote is a separate radio circuit with its own battery that works the lock, unlock, trunk and panic buttons. A proximity fob adds hands-free entry and push-button start. Replacement can involve any or all of these, and a good visit begins by working out which ones you need.

Scene 1
Before a blank leaves the van, the locksmith confirms that the person asking for a key is entitled to one. Government photo identification is the first piece. The second is a document tying that person to this vehicle: the vehicle permit with the VIN on it, an insurance slip, a lease, or fleet paperwork for a company car. The VIN on the paper is compared with the one stamped on the dash and printed on the door label. A car bought last week and still in the seller's name, an estate vehicle or a family member's car each has its own paper trail, and mentioning it on the phone means the right document is at hand.
Scene 2
Many vehicles from the last two decades use an internal-cut key, sometimes called a laser-cut or sidewinder key, with a wavy groove milled into the flat of the blade instead of teeth along its edge. These are produced on a milling cutter that follows the code to a fine tolerance, because the wafers in a high-security lock have little forgiveness for an off-depth cut. The blank is clamped, the groove is milled on both sides, the burrs are cleaned off and the blade is checked in the lock for smooth travel. A blade that drags or catches is recut rather than forced.
Scene 3
A car key has an identity of its own: a blade profile, a transponder type, a remote frequency and a part number, and sometimes a key code printed on a tag. The locksmith notes these for you, along with the count of keys stored in the car, so the next spare can be prepared from the details rather than from scratch. Keep the note with your insurance papers rather than in the car. If the vehicle ever changes hands, the record also lets the new owner have the old keys erased and fresh ones made without guesswork about what the car uses.

Yes, for a vehicle that genuinely has no immobilizer, checked by VIN and equipment rather than assumed from age, since several early-2000s vehicles already shipped with a factory immobilizer and coded key. Where that is the case, it is the simplest key work there is: a blade cut to the factory code from the VIN or to a reading of the door lock, rather than copied from a worn original. If the ignition has become sloppy, the locksmith can rebuild it in the same visit.
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.
The broken piece is drawn out with an extractor that grips it rather than pushing it deeper, and the cylinder is checked for damage. The head of the key, if it survived, still holds the chip and the remote, so it can be rebuilt around a new blade in a new case without any programming. If the whole key was lost with the break, a fresh transponder key is cut to code and programmed as usual.
