Why get a spare now
With a working key in hand, a new one can usually be matched to it. Without one, a key has to be made from your vehicle’s details and programmed from scratch, which takes more steps. A spare turns a future emergency into a minor inconvenience.
- You bought a used car that came with only one key
- Two or more people in your household drive the same car
- Your current key is starting to wear, crack or act up
- You simply don’t want to deal with a lost key later
A copy isn’t always a working spare
Most cars from the late 1990s on use a transponder chip in the key. A hardware-store copy can match the cuts on the blade, so it opens the doors, but without a programmed chip the engine won’t start. A useful spare matches both: the blade and the chip.
For remotes and push-to-start keys, a spare also needs its buttons or proximity function programmed. See key fobs and smart keys.
Kiosk, dealership or mobile locksmith?
Each option fits a different situation:
- Self-service kiosk or key counter. Convenient when you bring a working key to copy. What it can handle depends on the machine and your vehicle, so check before relying on it for a chipped or smart key.
- Dealership. Supplies keys for the brands it sells, usually through the parts or service department. Ask whether the key is in stock and whether the car needs to come in.
- Mobile automotive locksmith. Comes to the car, which helps when the new key has to be programmed to the vehicle. What can be done on site depends on your vehicle.
Not sure which fits your key? Call with your year, make and model and ask.
Where to keep your spare
- At home, somewhere you’ll remember, away from the front door
- With someone you trust who lives or works nearby
- Not in the car, and not in a magnetic box under it
What we’ll ask
Your year, make and model, the kind of key you have now, and how many spares you want. If your current key is worn or damaged, mention it; you may want a replacement rather than a copy of a worn key. If it has also become hard to turn in the ignition, see ignition and broken keys.
