Lost your car key? The replacement cost depends almost entirely on what kind of key your car uses. Here are the typical 2026 ranges and what pushes the price up or down.
What drives the price
- Key type — a basic metal key is cheap; a transponder (chip) key, remote fob or push-to-start smart key costs more because it must be programmed to your car.
- Make and model — luxury and newer vehicles use proprietary, higher-cost keys and programming.
- All keys lost — if you have no working key at all, the job takes longer (the system must be accessed from scratch), so it costs more than copying a spare.
- Where you go — a dealership adds a tow and markup; a mobile auto locksmith comes to you.

Why 'all keys lost' costs more
If even one working key exists, duplicating it is quick. With no key at all, the locksmith has to originate a new key to the vehicle's security system — more time and equipment, so a higher price. Keeping a spare is the cheapest insurance against this.
Dealer vs. mobile locksmith
Dealerships usually charge more and often require a tow (you can't drive a car with no key). A mobile locksmith comes to your home, work or the roadside, makes and programs the key on-site, and is typically cheaper — no tow bill, no waiting room.

How to pay less
- Make a spare now, while you still have a working key — it's far cheaper than an all-keys-lost job later.
- Call a mobile locksmith for an upfront quote before you tow to the dealer.
- Have your VIN and exact year/make/model ready so the quote is accurate.
