You have checked your pockets, the kitchen counter and the car park, and the key still has not turned up. Before ordering a replacement, tell the locksmith whether you have another key that can start the car.
So with every key lost, ACME Locksmith in Phoenix gives $220 to $350 for a transponder key and $250 to $800 or more for a smart fob, made and programmed at the vehicle.
I will show you how those jobs differ from copying a spare, what programming includes, and what three US owners paid. A remote that opens the doors and a key that starts the engine are not always the same thing.
Replacement Prices When All Keys Are Lost
ACME’s Phoenix replacement guide gives these totals for making a new key when no working key remains, checked October 24, 2026:
The same page separates the key or fob, code retrieval and cutting, and electronic programming. Its published total ranges are complete estimates; adding all the highest component prices would describe a different bill.

Another provider, Automotive Locksmith Indianapolis, publishes $150 to $220 for a transponder key and $220 to $350 for a smart proximity key. Its FAQ describes mobile key making even when every key is gone.
Those menus are useful starting points for their service areas. European vehicles, unusual security systems and the exact fob can require a separate offer, so provide the year, make, model and current key situation.
A Working Spare Changes the Job
If you can still drive the car, take it and the working key to the provider. ACME explains that its in-shop copy service avoids the work involved in making a key from scratch at a stranded vehicle.
Its separate car-key service page gives $10 to $25 for a basic no-chip duplicate and $64 to $199 for a transponder key cut and programmed. It labels that menu as a starting guide rather than an all-keys-lost offer.
Indianapolis advertises a spare made while a working key remains at $65 to $180. I would arrange that while you can bring the car in, rather than assume the low duplicate price applies after the last key disappears.
What Should the New Key Actually Do?
ACME distinguishes plain metal keys, chipped keys, laser-cut keys and smart fobs. The blade shape and the electronics are separate questions: a laser-cut blade does not tell you whether programming is required.
- A mechanical blade must fit the intended lock. An emergency door key may provide access without being able to start the engine.
- A transponder must be accepted by the vehicle’s security system, as well as having the correct blade where one is used.
- Remote buttons and proximity starting need the correct compatible electronics. Include any emergency blade cutting in the agreed work.
Before leaving, try every promised function with the technician: door entry, engine starting and remote buttons. Have any surviving key tested too, and ask how the missing key’s electronic access will be handled.

If your key is simply locked inside, our locksmith cost guide covers opening the car. Buying a new key is a different job from retrieving a working one.
What Owners Paid for Keys and Fobs
These older reports include a full fob service, a chipped-key bill and a door-only blade. Keeping their different functions beside the prices makes them easier to compare:
- In a March 24, 2021 post, a Savannah, Georgia Tacoma owner reported $235.19 for a programmed fob and two keys at Car Keys Express. The truck had come with one remote.
- A New Jersey Lincoln owner wrote on February 2, 2016 that they had paid $65 to have a key made, in a discussion about chipped Ford keys. The bill was not itemized.
- A southeastern Illinois Tacoma owner paid a locksmith $10 for a correctly cut door-opening key, posted March 25, 2020. That account does not establish an engine-starting key price.
The Savannah post includes programming, while the Illinois example is only about door access. Neither the old amounts nor a cheap blade should be used as today’s price for replacing a lost smart fob.
Before Buying a Fob Online
ACME accepts customer-supplied keys when they are compatible. Get the provider’s approval for the exact part before ordering, including whether it will accept a used or aftermarket fob.
Ask whether its price includes the fob, programming, blade cutting and the mobile visit, and what happens if the supplied part cannot be programmed. A low hardware price leaves those other questions unanswered.
An aftermarket remote-start system adds another compatibility question. Our remote starter installation guide covers that accessory; an extra engine-starting key does not automatically add remote start.
Have proof of ownership and identification ready, and ask which documents the provider requires. If the vehicle cannot be serviced where it sits, confirm any transport arrangements before committing to a dealer appointment.
Car Key Questions You Might Have
How much is a car key replacement without the original?
ACME’s Phoenix all-keys-lost guide gives $50 to $180 for a basic metal key, $220 to $350 for a transponder, and $250 to $800 or more for a smart fob made at the car.
Is programming included in a replacement price?
ACME’s all-keys-lost transponder and smart-fob totals include programming. A listing for a fob or blank alone may not.
Can a locksmith make a key without a working copy?
ACME describes making a key from the vehicle’s key code and programming it at the car. The provider must confirm support for your particular model and security system.
Does a cheap door key also start the car?
Not necessarily. A mechanical blade may open a lock while the engine still requires an accepted transponder or smart fob.
