A locksmith can create a basic key for you at a less price than you would pay in the dealership. You could also ask a neighbor or friend who is able to program transponder keys for aftermarket use (which are cheaper than the keys that are factory-made) to cut you a spare and have it programmed. It is essential to have a spare key because modern vehicles won't start when the key does not have the correct chip.
car key replacements look like mechanical keys, however they are actually equipped with an electronic chip inside the base of their plastic shape that communicates with your vehicle's computer system. Your car will accept the code that is on the chip, but will not start if you try to use another code.
If your spare key has a chip, you'll need to bring it to a dealer to get it programmed. The dealership will require an exclusive machine for cutting and programming the key.

Transponder Keys

Transponder keys are a fantastic way to discourage theft because they require two components for the car to start that is the transmitter (transponder) in the key and the receiver that is connected to your immobilizer system. Without both the key and the immobilizer system present the car will not start and is impossible to connect hotwire.
The key chips are programmed with a unique serial number that is unique to the vehicle you own. The serial number of the key is sent to the immobilizer of the car, and then checked to be in line. If it does the engine starts, it will. The only thing that could be a hindrance to this security feature is a device that can read the chip and match it to another car.
When you get a transponder key replaced you'll need to go to an authorized locksmith who has the necessary equipment to reprogram the key to your vehicle. Some car dealerships offer this service, however they are generally more expensive than a independent locksmith because of their costs.

They also have built-in chips to stop the copying of keys by unauthorized people from starting your car. They have a unique code that must be programmed into your car to unlock it and begin it. This extra layer of security is a fantastic option to protect your investment and deter thieves who might be trying to steal your car to make parts or sell it to.
In terms of design laser-cut keys are different from mechanical cut keys due to having smaller grooves that have been carved out of the key. The shaft of the key is more substantial, which is another indication that this isn't a standard car key. Locksmiths usually use milling machines to cut keys. This machine is similar to a drill bit and it's designed to remove metal in very precise angles.
These are the safest keys you can buy for your vehicle. They are difficult to duplicate and must be cut by a licensed locksmith or dealer. They're not made with traditional keys. Instead, they are made of a tiny piece of steel that is cut into a specific code at the factory and then cut using a laser. This kind of key is able to endure a lot of wear and tear and is one of the best options to protect your vehicle.

Smart Keys Keys
Unlike the traditional single piece of metal, smart keys utilize RFID, or radio-frequency identification, to communicate with the car. This means that they are equipped with a tiny chip that contains an encrypted code that is unique to each key. Whenever you unlock your car's doors, or open the trunk the key transmits a signal to your vehicle's onboard computer. The computer then signals the appropriate frequency and allows you to connect to your car and start it.
The chip inside the smart key has several security features to protect it from theft. The key emits a low-frequency signal, which can only be detected by your car. If the computer onboard detects this signal, it will transmit a different one which is unique and only your car is able to understand. This will stop a tech-savvy criminal from using a pulse generator in order to "fool the system" and do the key work on other vehicles.
In addition to locking and opening the car, some smart keys also have additional functions such as storing specific preferences for drivers remotely opening windows, the sunroof, among others. These functions can be accessed by activating the proximity sensor on the key fob by pressing a button or, in some cases it is as simple as twisting a tiny piece of metal inside the key.
Certain key fobs can be opened by placing the dead key in a slot, or by placing it near an inductive coil on the dashboard. Some even come with an emergency (fully mechanical) key blade that is hidden inside the key to enable this.
To replace a smart key, you'll need an appointment with a dealer, who will either purchase the replacement or stock it. They'll also need to program the new key to recognize the car you are driving. But, you can go to a locksmith shop to have your replacement key fob programed and replaced. Locksmiths may charge more than the dealer, but they'll likely be able to complete the job faster and at a lower cost.
