How Much Does Car Key Replacement Cost? Prices by Key Type
Published Oct 23, 2026 · 6 min read · By Hassan, Owner of Roadmate Services
A car key used to be a strip of metal. Now it is a small computer on a keyring, and it is priced like one. Car key replacement cost runs from about $50 to $900 in published market figures, with a typical key around $250. A locksmith usually charges 30 to 50 percent less than a dealer.
If your key is not lost but locked inside the car, you need a lockout, not a new key. In Columbus that is $75 to $175 with us. If a child or pet is locked inside, call 911 first.

Car key replacement cost by key type
Market figures from locksmithrates.com: locksmith range in the heading, dealer range in the text.
Basic metal key: $50 to $180
No chip and no buttons, usually on older cars. A dealer charges about $120 to $250 (market figures). A copy of a working key costs far less. The basic key is the flip phone of car keys: plain, cheap and never needs charging.
Transponder (chip) key: $120 to $280
A chip in the head talks to the car, and the engine will not start without it. The key must be cut and programmed. Dealers charge about $230 to $450. Carfax puts most transponder keys under $250.
Remote head or switchblade key: $150 to $350
A key and lock buttons in one, sometimes with a blade that flips out. Dealers charge about $300 to $600, and Carfax puts a switchblade key at $200 to $300. If only the buttons stopped working, read why a key fob stops working before you buy anything.
Smart key or push-button fob: $250 to $550
The key stays in your pocket and the car starts with a button. Dealers charge about $400 to $900, and luxury brands can go past $1,000 (market figures).
Why does a lost car key cost more than a spare?
With a working key, the locksmith copies what already works. With all keys lost, they need the key code and must program the car from scratch. Published figures add about $150 to $400 for that.
Some smart-key cars can only be done at the dealer. In Columbus, our tow range is $125 to $275 for about 1 to 15 miles; longer tows are quoted by phone. More in how much it costs to tow a car.
Lost keys have a talent for hiding in the one coat pocket you never check. Check it twice.
Mobile car key replacement: what it costs and when it helps
A mobile locksmith drives to the car, then cuts and programs the key on the spot. Published figures put the trip at about $50 to $100 on top of the key, and after hours adds about $50 to $100 more. With every key lost, that can still cost less than a tow to the dealer.
Not everything is a roadside job, and this one is not ours. Our technicians do not cut or program keys. Our locksmith partners do, smart keys and key fobs included, and we can put you in touch with one. It is the pizza delivery of key cutting, minus the pizza.
Dealer or locksmith: which is cheaper?
Usually the locksmith. Consumer Reports heard from a mobile locksmith who charges 30 to 50 percent less than dealers. It also found that many European brands only let the dealer program their keys.
Under warranty, call the dealer first; most new-car warranties cover a fob that fails. The dealer does have one advantage: the coffee in the waiting room.
Keys locked in the car? You may not need a new key
If you can see your key on the seat, it is a lockout. We open the car, and in Columbus that is $75 to $175, with the price shown before anyone drives out. After hours, at weekends, or on a smart-key or luxury car it can cost more, quoted by phone or on site. Our locksmith cost guide for car lockouts compares the options. Your keys are safe; they are just on the wrong side of the glass.
6 ways to lower your car key replacement cost
- Get a spare made while you still have a working key. Lost keys cost the most.
- Check your new-car warranty or extended warranty before you pay.
- If only the case is broken, a new shell costs about $20 and keeps the old electronics (Consumer Reports).
- Try a new fob battery first; see our key fob battery guide.
- Program two keys in one visit. Dealers often charge one programming fee per visit, so the second key costs less.
- Get the full total, trip included, before anyone comes out. The Connecticut Department of Consumer Protection also suggests a written quote before work starts.
A spare key in a kitchen drawer does nothing for years, and then saves you a few hundred dollars.
