Keys Replacement For Cars
You can get a replacement key for a mechanical key in any hardware shop. The key needs to be programmed either by a locksmith or a dealer.

Mechanical Keys
You can still purchase mechanical keys for your car which you insert into the ignition lock cylinder to start your car. If your vehicle is equipped with one of these, it's relatively affordable to replace the fob and key (if lost or stolen).
A locksmith can make you an original key at a lower cost than what you pay at a dealership. You can also ask a neighbor or friend who knows how 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. Getting a spare is important because modern cars won't start if a key without the correct chip is used.
automotive key replacement resemble mechanical keys, but they have an electronic chip hidden within the base. The chip communicates with the computer system in your vehicle. The car will accept the code on the chip, but it will not start if you use another code.
If your spare key is equipped with chip, you'll need to bring it to a dealership to have it programmed. The dealership will need an exclusive machine for cutting and programming the key. These machines are only available at specific dealerships, and it's unlikely that a locksmith will have the tools needed to make an engraved key using a laser transponder.

Certain key fobs come with a spring-loaded key that folds into the enclosure and opens doors or is operated by a proximity sensor to open and start your vehicle.
Transponder Keys
If your car was constructed in the last 10 years or so it's likely to use transponder keys. These keys are equipped with a microchip in the key itself as well as an internal receiver in your car which are both programmed to communicate with each other to start the vehicle.

The key chips are programmed with a serial number that is unique to the vehicle you own. When the key is inserted into the ignition the serial number is then sent to the immobilizer of the car and verified that it is in line and allows the engine to start. This security feature can only be defeated by a special device which can read the chip and match it with a different car.
When you get a transponder-related key replaced, you'll need to visit an locksmith with the tools needed to reprogram the key into your car. Some car dealerships provide this service too, but they tend to be more expensive than an independent locksmith due to their expenses.

This additional layer of security is a great way to protect your investment and deter thieves who may be trying to steal your car for parts or sell it to.
In terms of design Laser-cut keys are different from standard mechanical cut keys, as they have smaller grooves that have been carved out of the key. The key shaft is also larger, which is a sign that this is not a standard car key. Locksmiths typically make use of milling tool to cut these types of keys. This type of machine looks much like a drill bit and is designed to cut metal with extremely precise controlled angles.
These are some of the most secure keys you can buy for your car, as they are extremely difficult to duplicate and only cut by the dealer or a licensed locksmith. They're not made with traditional keys. Instead, they are constructed from a small piece of steel that is cut to a code at the factory, and then cut with the laser. This kind of key can endure a lot of wear and tear, and is among the best options to protect your vehicle.

Smart Keys Keys
Smart keys communicate with the vehicle using radio-frequency identification (RFID) instead of the traditional single piece carved metal. This means they have a tiny chip that contains an encrypted code that is unique to each key. The key sends a signal to the onboard computer of your vehicle every time you open the doors or open the trunk. The computer then will prompt the right frequency that allows you to start your vehicle.
The chip of the smart key comes with a variety of security features to guard against theft. First the key emits a low-frequency signal that isn't detected by any receiver but your vehicle. If the onboard computer detects this signal, it will prompt a different one that is an exclusive sequence that only your vehicle can comprehend. This prevents a tech-savvy criminal from using an external generator to "fool" the system and create the key function for other vehicles.
Some smart keys have special features, such as the ability to store preferences for drivers and opening windows remotely, or the sunroof via remote, and many more. These are accomplished by activating the key fob's proximity sensor or pressing a button on the key, or, in some instances, by twisting a tiny metal component inside the key.
Most of these key fobs feature an unlock button that opens the doors on their own However, some key fobs have another method of opening them with a slot or by placing the dead key near a spot on the dashboard, where it houses an inductive coil which can transfer energy. Some even include an emergency (fully mechanical) key blade that is hidden inside the key to enable this.
Replacing a smart lock requires an appointment with a dealer, where they can request the replacement or have it on hand. The dealer will also need to program your new key to identify your vehicle. However, you can also go to a locksmith shop to have your replacement key fob programed and replaced. Locksmiths will cost more than a dealer, but they will complete the task faster and at a lower cost.
