How do you get a new transponder key?
You get a transponder key in three steps: a blank key, a cut key blade, and a programmed chip. A transponder key needs all three, or the key will not start the car.
A locksmith cuts the key to your car and programs the chip to the immobilizer, so the transponder key starts the vehicle. Most people call a pro for car keys because a locksmith makes the key on site. A dealership can make car keys too, but you often tow the car in and pay more for the key.
What is a transponder key?
A transponder key is a car key with a chip in the head of the key. The chip is the transponder, and it sends a code to your car when you turn the key in the ignition. The immobilizer reads the transponder chip, and if the code matches, the car starts.
This is why a transponder key needs programming, not just cutting. A cut key with no chip turns the lock but will not start the car, because the immobilizer requires the transponder chip. In fact, almost every car since the late 1990s uses a transponder key or a key fob, so new car keys need a cut blade and a programmed chip that work together.
Steps to make a transponder key
A locksmith follows the same steps to make transponder keys for any car. Here is how car keys are made.
- Get a blank key or key fob for your car make and model
- Cut the key blade to match your car lock and ignition
- Program the transponder chip in the key to your car immobilizer
- Test that the new key starts the vehicle
Each step needs the right tool. The tech carries blank car keys, a key cutting machine, and a chip programmer, so the key is done in one visit. If you want a spare key, the same steps add a second car key that works.
Can a locksmith replace your car keys?
Yes, a locksmith can replace your car keys, whether you lost one key or every key. A locksmith cuts and programs transponder keys, key fobs, and remotes for most makes and models. See our car key replacement service for every make.
To replace a car key, the locksmith reads the car, cuts a fresh key blade, and programs the chip so the new key starts the vehicle.

Where to get car keys made
You can get car keys made at three places: a locksmith, a dealership, or an auto parts store. Each one handles a transponder key a bit differently.
A dealership makes car keys, but you pay dealer prices and may wait days for the key. An auto parts store sells a blank key and may cut it, but many cannot program the transponder chip. An automotive locksmith cuts and programs car keys on site for less than the dealer. To find a locksmith who makes car keys, look for one that lists car key replacement and key fob programming, and read the reviews.
How much do transponder keys cost?
A transponder key costs about $50 to $250, depending on the car and the type of key. The price of a basic transponder key is low, while a key fob or a push to start key costs more.
In most cases, the price depends on the make, the model, and whether the key is a plain transponder key or a smart key fob with remotes built in. A locksmith price is usually lower than the dealer for the same car key. For a full breakdown of prices, see our locksmith pricing and our guide on car key replacement cost. A spare key made at the same time costs less than a first key.
Car key replacement prices in Las Vegas
The price of a car key replacement depends on the vehicle and the type of key. A basic transponder key has a low price, a key fob has a higher price, and a smart key with remotes has the top price.
To replace a lost key, expect the price to add a bit for the extra work, since the locksmith makes the key from the vehicle. However, a spare key has a lower price, because there is a working key to copy. Ask the price up front, and a locksmith will replace the car key for a fair price, well under the dealer price.
What if you lost all your car keys?
If you lost all your car keys, you can still get a new key, but it takes an extra step. With no working key, a locksmith makes the key from scratch.
The locksmith reads your car lock or pulls the key code from the VIN, cuts a fresh key blade, and programs a new transponder chip. This all keys lost job costs more than a spare, because there is no key to copy. If you are locked out and every car key is lost, an automotive locksmith opens the locked car and makes the key on the spot. By providing the VIN and proof you own the car, a locksmith can find the key code and cut a key. The law requires proof, so bring your ID, and you can find a new key even when all keys are lost. You can confirm your car with the NICB VINCheck tool before you order a key.
Transponder key, key fob, or remote?
Car keys come in a few types, and the type changes how the key is made. Knowing your key type helps you get the right car key.
- Transponder key: a cut key with a hidden chip, turns in the ignition
- Key fob: a remote with buttons plus a chip, often with a cut key blade
- Push to start: a smart key fob with no blade, uses proximity remotes
- Basic remote: unlocks the car but the key does not start it alone
A locksmith replaces all of these, from a plain transponder key to a smart key fob and remotes. A key fob and push to start remotes cost more than a basic transponder key, since they add more electronics and programming to the key.
Why a transponder key needs programming
A transponder key needs programming because the chip has to sync with your car. The immobilizer requires the right code from the transponder chip before the car will start.
So cutting the key is only half the job. The tech programs the chip so the key and the car talk to each other. Without programming, the transponder key turns but the car will not start, so the programming step is what makes the new key work.
Program a transponder key, key fob, or remotes
A pro can program a transponder key, program a key fob, and program the remotes for your vehicle. The program step syncs the chip to the car, so the key will start it.
To program a new key, the locksmith links the transponder chip to the immobilizer. To program a key fob, the locksmith adds the remote buttons and the chip. If you need to program remotes for a lost fob, a locksmith can program the vehicle on site, and often program a spare key at the same time.
How long does it take to make a car key?
A locksmith makes a new car key in about 20 to 40 minutes on site. Cutting the key blade is quick, and programming the transponder chip takes a few more minutes.
However, a dealership can take days if the key has to be ordered, and you may need to tow the car. A locksmith comes to you, so lost car keys do not strand you for long. When you need a car key fast, a mobile pro beats the wait at the dealer.
