Keys Replacement For Cars
You can get the replacement key for a mechanical key at any hardware shop. This key will need to be programmed either by a locksmith or dealer.
Smart keys are more complex and require a trip to the dealer to connect them to your vehicle. These types of keys are usually expensive, but some car insurance companies will cover the cost.
Mechanical Keys
You can still purchase car keys that are solely mechanical, like the ones you place in an ignition lock cylinder and turn to start your car. If your vehicle is equipped with one of these, it's affordable to replace the key and fob (if lost or stolen).
A locksmith can make you new keys for less than you would buy from a dealer. You can also ask a neighbour or a 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 then program it. It is crucial to have a spare key since modern cars won't start when the key does not have the proper chip.
Transponder keys look a lot like mechanical keys, but they have a hidden electronic chip inside the base of their plastic design that communicates with your vehicle's computer system. Your car will accept the code on the chip, but it will not start if you try to use another code.
If your spare key contains chips it must be programmed by a dealer. The dealership will need an exclusive machine for cutting and programming the key. These machines are available only at certain dealerships. It is unlikely that a locksmith will have the equipment necessary to create a key with transponder.
Keys with remotes are expensive to replace, particularly when you require an extra. If you have only the shank of your key missing and a working replacement fob, you could try reprogramming your fob on your own. However, it could be time-consuming and challenging. If you've lost your entire fob and key however, a dealer is your best bet.
There are other types of car keys that require a more specific set of skills to replace, for example flip keys and smart keys. They are more complex and must be replaced by a dealer. Certain key fobs operate by a proximity sensor or a door opener that is spring-loaded.
Transponder Keys
If your car was built in the recent 10 years or so it's likely to use transponder keys. The keys contain a microchip in the key itself and a receiver in your car that both have been programmed to communicate with each other to start the car.
Transponder keys are an excellent way to discourage theft because they require two parts for the car to be able to start which is the transmitter (transponder) inside the key and the receiver that is connected to your immobilizer system. Without both the key and the immobilizer system being in place, the car won't start and is impossible to hotwire.
These key chips are programmed with a serial number that is unique to the vehicle you own. When the key is inserted into your ignition, the serial number is sent to the cars immobilizer and checked to ensure that it is in line, it will then allow the engine to start. This security feature is only overcome by a specific device that can read the chip to match it with a different car.
You'll have to find a locksmith that has the tools to reprogram your key. Some car dealerships provide this service, however they are generally more expensive than a independent locksmith because of their costs.

Certain of the more basic chip keys can be cloned at the majority of auto parts stores but you must know the serial number of the original key to ensure that the correct information is transferred to the new key. Many people make a mistake visiting their dealer to purchase an exact copy of a chip key and end up paying inflated prices.
Laser-Cut Keys
Laser-cut keys are also known as sidewinder key because of the distinctive winding cut that is made on the key shank. They add an extra layer of security to your car. Because it requires specialized equipment to duplicate these keys, they're a great security measure against auto theft.
Like transponder keys. They have built-in chips that block unauthorised copies of keys from starting your car. They also have a unique code on the key, which needs to be programmed for your particular vehicle in order to unlock it and start it. This extra layer of security will safeguard your investment, and deter thieves from trying to steal your vehicle for parts or to resell it.
In terms of design, laser-cut keys are slightly different from mechanical cut keys, as they have smaller grooves that have been carved out of the key. The shaft of the key is larger, which is a indication that this isn't a regular car key. Locksmiths usually employ a milling machine to cut keys. This kind of tool looks like a drill and is designed to remove metal at very precise, controlled angles.
These are some of the most secure keys you can purchase for your car, because they're extremely difficult to duplicate and only cut by a dealer or a certified locksmith. In contrast to traditional keys, they're made using a small piece of steel which is shaped into a code and then cut using a laser in the factory. This kind of key can be able to withstand a great deal of wear and tear, and is one of the best options for protecting your vehicle.

Smart Keys Keys
Smart keys communicate with the vehicle via radio-frequency identification (RFID) instead of the conventional single piece of carved metal. This means they come with a small chip that has 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 computer onboard. The computer then prompts the appropriate frequency, allowing you to access your car and start it.
The chip in the smart key comes with a variety of security features to guard it from theft. First the key emits a low-frequency signal which isn't detected by any receiver but your car. If the onboard computer detects this signal, it will display an alternative one that's an individual sequence that only your vehicle will comprehend. This will stop a criminal with a high-tech background from using an external pulse generator to "fool" the system and make the key work for other vehicles.
In addition to locking and opening the car, some smart keys have special features like storing specific driver preferences, remotely opening windows or the sunroof, among others. These functions 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.
The majority of these key fobs feature an unlock button that opens the doors by themselves however some come with another method of opening them with a slot or by placing the dead key near an area on the dashboard, where it is able to hold an inductive coil which can transfer energy. Some even have an emergency (fully mechanical) key blade concealed in the key to allow this.
Replacing automotive car key replacement with a smart chip typically requires a visit to the dealership, where they will either have the replacement on hand or make it available for you to purchase. The dealer will also need to program your new key to identify your car. You can go to a locksmith shop to have your replacement key fob programmed and replaced. A locksmith might charge more than a dealer, but they'll likely be able to complete the job quicker and less expensively.
