Spare Car Keys: The Cheapest Key You Will Ever Buy
- Spare, chip key
- $70 to $180 rough
- Same key, all lost
- $150 to $300 rough
- Time
- Often 20 to 45 minutes
Most people learn this the hard way. A spare made while you still have a working key costs a fraction of a key made from nothing. If you have one key left, this is the page to act on.
Why the Gap Is So Big
With a working key in hand, the tech copies the cut and adds one more chip or fob to your car. With no key, the tech has to make a key from scratch, often pull a security PIN, and sometimes reset every key the car knows. Our cost table shows a gap of roughly $80 to $300 depending on the key type.
Where to Get a Spare Made
| Where | Good for | Watch for |
|---|---|---|
| Hardware counter or kiosk | Plain metal keys, some chip clones | Many chip keys and all push-start fobs are beyond them |
| Mobile automotive locksmith | Chip keys, remote heads, flip keys, most smart keys | Ask if the fob is new or refurbished, and the warranty |
| Dealer | Any key for the brands it sells | Higher prices, appointments, some keys ordered |
Smart Ways to Save
- Some cars let you add a key yourself. Many older Ford, Lincoln, Mazda and some GM and Chrysler models let you program a new chip key at home if you already have two working keys. The steps are in the owner's manual or a dealer service bulletin. You still need the new key cut.
- Ask for a "valet" or "emergency" key. On some push-start cars a cheaper metal key that only opens the door is an option. It will not start the car, but it ends lockouts.
- Do not hide the spare on the car. Magnetic boxes under the bumper are the first place a thief looks. Keep it at home or with someone you trust.

Can I copy a car key at a hardware store?
A plain metal key, yes. Some kiosks clone certain chip keys too. Most push-start fobs and many newer chip keys need a locksmith or dealer.
Is it worth getting a spare key?
