The new key must also be programmed to work with the immobilizer system of your vehicle. This can be done at a dealer or by a locksmith that has an instrument for programming keys specifically for your vehicle. Many locksmiths offer mobile services which allows them to come to you and cut keys on the spot.

The process is easy for older cars and requires just copying the key.

The key can open doors and turn off the ignition, but it won't start your engine.

Laser-cut keys are offered in cars equipped with transponder chips. Keys are square or blunt with identical cuts on the flat sides.

Most car brands have agreed on a common standard for key programming and it should be relatively easy to find out how to program the new key for your particular vehicle.

How does key cutting get done?

Modern car keys come with a transponder chip that communicates with the car's computer system to initiate the engine. This communication happens when the key is within range of the vehicle's key recognition sensor, which is usually near or in the vicinity of the ignition.

To duplicate a key for a car using transponder, a locksmith uses a special machine known as a sidewinder key duplicator. This machine looks like a small CNC laser cut or mechanical and can create copies that are shaped like your original keys. These machines are not available to the public. Only a certified and qualified locksmith can use these machines.

While these machines are powerful, they can be difficult to operate and require a great deal of knowledge. This is why it's essential to find a locksmith who has the right knowledge and training to create new keys. A reliable locksmith can also assist you in reprogramming existing keys. The process is similar to initial programming. However, the locksmith might use a different method that involves connecting to the vehicle’s computer system through the OBD II connector.

A professional can program and cut a spare key in just a few minutes. It's better to design an additional key with your own specifications in case you lose your key rather than risking losing your vehicle and having to pay hundreds of pounds in the dealer to replace it.

In addition to cutting your keys and having them programmed in a cost-effective manner, you can save on spare keys by purchasing a blank keyshell at your local hardware store and then having it copied by a locksmith. Then, you'll need to follow the instructions in the owner's guide on how to program this new key for your vehicle.

You'll need to transfer the internals from your old key head, including the chip and battery for the remote fob to the new one.

What is the price of cutting and programming key pieces?

The type and complexity, the design of the key (including any unique features) and the method used to cut it are all elements that affect the price. The cost may also differ depending on the location and locksmith you choose.

A basic car key that has an iron key-blade to open and start the engine is generally cheaper to copy than other key types like key fobs. This is due to the fact that these kinds of keys do not contain transponder chips that need to be programmed into the vehicle's ignition system. This involves setting a signal to recognize the key and transmitting a signal that is in line with the voltage that is set in the car's electronic control unit (ECU) which allows it to start.

You'll need to speak with an expert with the right tools and software to program a key fob with transponder. This could be a local locksmith or dealer key replacement specialist. The ECU needs to be scanned in order to obtain the key code required to program the remote. The code is then entered into the key programming and cutting software to verify that it is compatible with.

Contrary to other types of keys the majority of transponder chip keys have to be programmed by a professional from a dealership for them to function properly. This is because the chip in the key has to be programmed according to the unique key code stored in the car's computer. The dealer will have the hardware and software needed to program the key, and also the proper programming codes.

While cloning can be an affordable option for those who want a spare car key it's not the ideal option if you've lost your keys. Cloning is a good option however it does not send a signal to the vehicle's computer. This means that in the event that your car key is stolen, you will still be able to start your vehicle. Instead of risking the consequences of losing your car keys, always take the extra step to have a spare key cut and programmed, especially for cars with modern technology.

If you are looking for a spare which is programmed to work in your car's system, then the procedure becomes more complex. To do this locksmith, they will need to know the identification number of your vehicle (VIN) which can be found on most official documents, such as the title and registration of your car. The locksmith will use this information to access the correct code and create a new, working key that's compatible with the vehicle.

Some locksmiths do not offer this service. You should look for one who does before making an appointment. A professional locksmith can ensure that you're getting the most cost-effective and efficient solution.

Many locksmiths offer a cloning service in addition to key programming and cutting. This is a cheaper option for those who have lost their keys or need a backup. Unlike the process of cutting a key that is more difficult it is cloning that uses the microchip inside the original key to read the information and create a duplicate that is compatible with your vehicle. This process is available in all Mister Minit branches and some of our mobile service vans. You'll need the original key along with the model, make, and year of your vehicle, to book an appointment.
