Mechanical Keys
You can still buy mechanical keys for your car which you put into the ignition lock cylinder to start your vehicle. If your vehicle is equipped with one of these, it's relatively cheap to replace the key and fob (if lost or stolen).
A locksmith can cut a basic key for you at a cheaper cost than what you would buy from a dealership.

Some key fobs feature an electronic key that folds into the enclosure and opens doors, or they're operated with the use of a proximity sensor to open and start your car.
Transponder Keys
Transponder keys are most likely to be used in vehicles constructed in the last 10 years. These keys have a microchip in the key itself and a receiver in your car that are both programmed to communicate with each other in order to start the vehicle.
Transponder keys can be an excellent method of preventing theft, as they require two elements to start the car: the transmitter inside the key and the receiver that is connected to the immobilizer. Without auto car key replacement and the immobilizer system present the car will not start and is impossible to hotwire.
These key chips are programmed with a unique serial number that is unique to the vehicle you own. The serial number of the key is transmitted to the immobilizer of the car, and then checked to match. If it does then the engine will begin. This security feature can only be defeated by a special device that can read the chip to match it with another car.

Many people make the mistake of going to their dealer for a copy of a chip key and end up paying overpriced prices.
Laser-Cut Keys
Laser-cut keys, referred to as sidewinder keys due their distinctive winding cuts to the shank of the key provide an additional layer of security to your vehicle. Because it requires specialized equipment to duplicate these keys, they're a great protection against auto theft.
Like transponder keys, they feature built-in chips that block duplicate keys from getting into your vehicle. They come with a unique code that must be programmed into your vehicle to unlock it and start it. This extra layer of security is a great option to protect your investment and deter thieves who could be trying to steal your car for parts or to sell it on.
Keys cut with lasers differ slightly from mechanically cut keys in terms of design. They have fewer grooves carved out on the key. The key shaft is larger, which is a sign that this is not an ordinary car key. Locksmiths usually employ milling machines to cut these keys. This machine is similar to a drill bit and it's designed to cut metal in very precise angles.
These are the most secure keys you can buy for your vehicle. They are extremely difficult to duplicate and can only by cut by a certified locksmith or dealer. They're not like traditional keys. They're constructed from a tiny piece of steel that is shaped into a code and then cut using a laser at the factory.

Smart Keys
Smart keys communicate with the vehicle using radio-frequency identification (RFID) instead of the traditional single piece carved metal. They are equipped with a chip that has a unique code, which is encoded on each key. Whenever you unlock your car's doors, or open the trunk the key sends a signal to your vehicle's onboard computer. The computer will then prompt the appropriate frequency to allow you to start your car.
The smart key's chip also includes a variety of security features to guard against 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 trigger another one that is an individual sequence that only your car can comprehend. This prevents a tech-savvy criminal from using an external pulse generator to "fool" the system and perform the work for other vehicles.
In addition to locking and starting the car, some smart keys also have additional functions such as storing particular driver preferences, remotely opening windows or the sunroof, and more. These functions can be accessed by activating the proximity sensor on the key fob by pressing a button, or, in some cases, by twisting a small piece of metal inside the key.
Certain key fobs are opened by placing the dead key in a slot or by placing it next to an inductive coil that is located on the dashboard. Some key fobs have a mechanical (fully emergency) key blade in the key.
Replacing a smart key typically requires a visit to the dealership, who will either have the replacement on hand or order it for you. The dealer will also need to program the new key to identify your vehicle. You can also visit a locksmith for the replacement key fob to be programmed and replaced. Locksmiths may charge more than a dealer, but they'll be able to complete the job faster and less expensively.
