Why does the year make and model matter for replacing a lost car key?
The year, make and model tell the locksmith which type of key your car uses and how a new one has to be set up to work with it. A plain metal key, a key with a chip inside, a remote fob and a push-to-start fob are four different jobs, and the vehicle decides which one you have.

It also decides what is possible away from a dealer. Not every vehicle can be keyed by an independent locksmith, so the make and model are the first things to settle before anyone talks about a visit.
Why the vehicle decides the job
Manufacturers change their key systems from one model year to the next. Two cars from the same maker can use different key shapes, different chips and different programming steps. A key that fits one will not necessarily start the other, which is why a locksmith needs the exact vehicle rather than a general description.
Most newer vehicles do more than turn a lock. The key or fob carries a coded chip, and the car has to recognise it before the engine will run. The new key has to be cut where the car needs a blade and then programmed to the vehicle. On a push-to-start car there may be no blade to cut at all, and the fob has to be paired with the car instead.
If the key was lost rather than broken, the old key matters too. Where the car supports it, the lost key can be removed from the vehicle's memory so it no longer starts the car. Whether that is available depends again on the year, make and model.
What you can check yourself
- Note the year, make and modelHave these ready, along with the trim or engine if you know it. It is the first thing a locksmith will ask.
- Look for a spare keyCheck at home, with family members or in a drawer you use for spares. A working spare can make the job simpler, and it shows what type of key your car uses.
- Describe the key you hadSay whether it was a metal blade, a key with a plastic head, a remote with buttons or a fob you carry in a pocket. This helps identify the key type.
- Find your vehicle papersRegistration or insurance for the vehicle, plus your own photo identification, are what the locksmith will ask to see.
When to call a locksmith
Call once you know the key is lost, or broken and not repairable, and you have the vehicle details to hand. One Call Locksmiths arranges the visit with an independent locksmith; call (866) 690-5848 and we will set it up. If a child or an animal is shut inside a vehicle, call 911 first.
The locksmith asks for identification and proof that you are entitled to the vehicle before opening it or making a key. That might be a driver's licence, plus registration or insurance. The locksmith looks at the vehicle and gives the price, and work starts only once you agree it. The estimate is free. Locksmith licensing varies by state, so check with your own state or city if you want to know what applies where you are.

- What affects the cost of a replacement car key?
