Mechanical Keys

You can still buy mechanical car keys, the ones that you put into the ignition lock cylinder to start your vehicle. If your car is equipped with one of these, it's relatively cheap to replace the fob and key (if lost or stolen).

A locksmith can cut a basic key for you at a cheaper cost than what you would pay in a dealership. You could also have someone close to you who knows how to program transponder keys that are made for the aftermarket (which are less expensive than factory keys) cut keys and then program them. It is essential to have a spare because modern cars won't begin when a key is not programmed with the proper chip is used.

Transponder keys look like mechanical keys, but they have a hidden electronic chip embedded in the bottom of their plastic design that communicates with the computer system in your vehicle. Your car will recognize the code in the chip and accept it, however it will refuse to start if another code is utilized.

If your spare key contains a chip that is programmed, it will have to be programmed by a dealer. You'll need an equipment that can cut the key and program it. These machines are only available at specific dealerships, and it's unlikely that a locksmith has the equipment needed to create a laser-cut key with a transponder.

Keys with remotes cost a lot to replace, particularly if you need a spare. If you have only the shank of your key missing and a working replacement fob, you can try to reprogramme your fob by yourself. However, it can be time-consuming and difficult. If you've lost your entire fob and key, however it's best to contact a dealer as the best option.

There are other kinds of car keys that require a more specific set of skills to replace, such as flip keys and smart keys. These are more complex and typically need to be replaced at the dealership. Key fobs can be operated by a proximity sensor or a door opener with a spring loaded mechanism.

Transponder Keys

Transponder keys are likely to be used in vehicles constructed in the last 10 years. The keys are equipped with an embedded microchip and an electronic receiver that is programmed to send a signal to start your vehicle.

Transponder keys are an excellent way to stop theft because they require two parts in order for the car to be started that is the transmitter (transponder) inside the key and the receiver connected to your immobilizer system. Without both the key and the immobilizer system in place, the car won't start and it will be impossible to connect hotwire.

The key chips are programmed with a serial number that is unique to your vehicle. The serial number of the key is then sent to the immobilizer inside the
In addition to locking and starting the car, certain smart keys also have additional functions like storing specific driver preferences, remotely opening windows or the sunroof, among others. These features can be accessed by activating the proximity sensor on the key fob by pressing a button or, in certain instances you can do this by twisting a small piece of metal inside the key.

Most of these key fobs come with buttons that open the doors for themselves, but some have another method of opening them by a slot or placing the dead key close to the dashboard, where it is able to hold an inductive coil that can transfer energy. Some key fobs feature an electronic (fully emergency) key blade that is inside the key.

Replacing a smart key typically requires a visit to the dealer, who will either have the replacement on hand or order it for you. The dealer will also have to program your new key to recognize your car. You can also visit an locksmith to get your replacement key fob to be programmed and replaced. Locksmiths may cost more than the dealer, but they'll likely be able to complete the job more quickly and for less.
