Keys Replacement For Cars
You can purchase a replacement key for a mechanical one at any hardware shop. However, the key will need to be programmed by a locksmith or dealership.
Smart keys are more complex and require a visit to the dealer to pair them with your vehicle. These keys are expensive, but many car insurance companies will pay for the cost.

There are still car keys that are purely mechanical, such as the ones you put into an ignition lock cylinder and turn to start your car. If your car is equipped with one of these, it's cheap to replace the fob and key (if lost or stolen).
A locksmith can design a new basic key for less than what you buy from a dealer. You could also ask a neighbor or friend who is able to program transponder keys (which are cheaper than the keys made by the factory) to cut you a spare and have it programmed. It is important to have a spare key because modern cars will not start in the event that the key does have the correct chip.
Transponder keys look a lot like mechanical keys, but they have a hidden electronic chip embedded in the bottom of their plastic shape that communicates with your car's computer system. Your car will recognize the code that is on the chip, but it will not start if you use another code.
If your spare key is equipped with a chip, you'll need to bring it to a dealer to have it programmed. The dealership will require an exclusive machine for cutting and programming the key. These machines are only available at certain dealerships, and it's not likely that a locksmith has the tools needed to make an engraved key using a laser transponder.
Keys with remotes are expensive to replace, especially when you require a spare. If you have just the shank of your key missing and a working replacement fob, you can try to reprogramme your fob on your own. However, it could be time-consuming and challenging. You're better off contacting an authorized dealer if you've lost both the key and the fob.
There are other types of keys for cars that require a more specialized set of skills to replace, like flip keys and smart keys. They are more complicated and usually have to be replaced at the dealership. Some key fobs are operated by proximity sensors or a spring-loaded door opener.
Transponder Keys
Transponder keys will likely be used in vehicles built within the past 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 a fantastic method to deter theft since they require two parts in order for the car to start that is the transmitter (transponder) inside the key and the receiver that is connected to your immobilizer system. The car will not start without the key and the immobilizer system.
These key chips are programmed with a unique serial number that is unique to your vehicle. When the key is inserted into your ignition, the serial number is then sent to the immobilizer of the car and then verified to make sure it is compatible and allows the engine to run. This security feature can only be overcome by a specific device that can read the chip and match it with a different car.
If you need a transponder-related key replaced, you'll need to visit an authorized locksmith who has the equipment needed to reprogram the key to your vehicle. Some car dealerships provide this service, but their overhead makes them more expensive than an independent locksmith.
It isn't easy to get an original key that comes with chip. The key needs to be cut on a specific machine in order to have the correct tracks in place which can later be programmed to assign the key to your car. This requires special software and the correct key cutter to get it done properly.
Some of the less complicated chip keys can be cloned at most auto part stores but you must know the serial number of the original key to ensure the correct information is transferred to the new key. Many people make a mistake visiting their dealer to purchase the clone of a chip key only to end up paying high costs.
Laser-Cut Keys
Laser-cut keys are also referred as a sidewinder keys due to the distinctive winding cut on the shank of the key. They add an extra layer of security to your car. Keys like these are a great deterrent to auto theft because they require specialized machinery to duplicate.
Like transponder keys. They have built-in chips that prevent unauthorized key copies from getting into your car. They have a unique number that must be programmed into your car in order to unlock it and start it. This additional level of security will protect your investment and stop thieves from trying to steal your vehicle for parts or to sell it.
Keys cut with lasers differ slightly from mechanically-cut keys in terms of design. They have fewer grooves carved out on the key. The shaft of the key is thicker, which is another sign that this is not a standard car key. Locksmiths usually employ milling machines to cut keys. This type of machine looks much like a drill bit and is designed to remove metal with extremely precise and controlled angles.
They're among the most secure keys you can buy for your car, because they're very hard to replicate and only cut by a dealer or a licensed locksmith. In contrast to traditional keys, they're made from a small piece of steel that is made into a code, and then cut with the laser in the factory. This kind of key can withstand a lot wear and tear, and is among the best choices for protecting your vehicle.
The key can be folded in the fob, or be released by pressing the button. The keys are typically used in German cars, and provide an extra layer of security against car thieves. The cylinder is robust and difficult to break into, making it extremely difficult for a thief pick or pick-lock the vehicle.
Smart Keys Keys
In contrast to the traditional single piece of carved metal smart keys utilize RFID, also known as radio-frequency identification for short, to communicate with the car. This means they have tiny chips that contain an encrypted code that is unique to each key. The key sends a message to the computer onboard of your vehicle every time you open the doors or open the trunk. The computer then signals the right frequency, allowing you to access your car and start it.
The chip of the smart key includes a variety of security features that protect against theft. First the key emits a very low-frequency signal which isn't received by any other receiver, not even your vehicle. If the onboard computer detects this signal, it will display an alternative one that's an individual sequence that only your vehicle can understand. This will stop a tech-savvy criminal from using a pulse generator 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, and more. These features can be accessed by activating the proximity sensor on the key fob, pressing a button or, in certain instances it is as simple as twisting a tiny piece of metal inside the key.
Most of these key fobs come with a button that can unlock the doors on their own, but some have another method of opening them with a slot or by placing the dead key in the dashboard, where it houses an inductive coil that is able to transfer energy. Some even include an emergency (fully mechanical) key blade that is hidden inside the key to allow this.
Replacing a smart lock requires visiting 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. You can also visit a locksmith for the replacement key fob to be programmed and then replaced. Locksmiths may charge more than the dealer, but they'll be able to finish the job faster and less expensively.
