Keys Replacement For Cars
If you have a basic mechanical key you should be able to get a replacement at any hardware store for affordable. However, this key must be programmed by a locksmith or dealer.
Smart keys are more complicated and require a visit to a dealer to pair them with your vehicle. They can be expensive, but many car insurance companies will cover the cost.
Mechanical Keys
You can still purchase car keys that are solely mechanical, such as the ones you put into an ignition lock cylinder and then turn to start your vehicle. If your car is equipped with one of these, it's inexpensive to replace the key and fob (if lost or stolen).
A locksmith can make you new keys for less than you would purchase from a dealership. You could also ask a friend or neighbor that knows how to program aftermarket transponder keys (which are cheaper than keys made by the factory) cut keys and have them programmed. Getting a spare is important because modern cars won't start when a key is not programmed with the correct chip is used.
Transponder keys look a lot like mechanical keys, however they have a hidden electronic chip embedded in the bottom of their plastic design that communicates with your car's computer system. The car will accept the code that is on the chip, but it will not start if you choose another code.
If your spare key is equipped with chip, you'll need to bring it to a dealership to have it programmed. You'll need a specific machine to cut the key and program it. These machines are only available through certain dealerships, and it's unlikely that a locksmith has the equipment needed to create keys that are laser-cut with a transponder.
Keys with remotes can be costly to replace, particularly in the event that you need an extra. If you have just the key shank missing, and a functioning replacement fob you can try to reprogramme your fob by yourself. However, auto replacement key could be time-consuming and difficult. It's better to go to an authorized dealer in the event that you've lost both the key and the fob.
There are other types of keys for cars that require a specialized set of skills to replace, for example flip keys and smart keys. These are more complex and typically need to be replaced at the dealership. Certain key fobs operate by proximity sensors or a spring-loaded door opener.
Transponder Keys
Transponder keys will likely be used in vehicles built in the past 10 years. The keys have an embedded microchip and a receiver that is programmed to send a signal to start your car.
Transponder keys are a fantastic method to deter theft since they require two parts in order for the car to start - the transmitter (transponder) in the key and the receiver that is connected to your immobilizer system. The car will not start without the key and immobilizer system.
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 sent to the immobilizer inside the car, and then checked to match. If it does the engine starts, it will. The only thing that can defeat this security feature is a device that can detect the chip and match it to another car.
You'll have to find a locksmith who has the equipment to reprogram your key. Some car dealerships provide this service, but their overheads make them more expensive than a locksmith who is independent.
Finding a new car key that comes with a chip it can be a complicated process. To program your car, the key has to be programmed on a specific machine. It requires specialized software as well as the right key cutter to cut it properly.
Some of the simpler chip keys can be copied at a variety of auto parts stores, but you must know the serial number of the original key to ensure that the proper information is being programmed into the new key. Many people make the error of visiting a dealer to have a chip key copied, and end with a bill that is higher than what they should.
Laser-Cut Keys
Laser-cut keys are also known as a sidewinder key due to the distinctive winding cut that is made on the key shank. They add an additional layer of security to your car. Keys like these are a great protection against auto theft since they require special equipment to duplicate.
Like transponder keys, they have built-in chips that block unauthorized key copies from opening your vehicle. They have a unique code that needs to be programmed into your car to unlock it and start it. This additional level of security is an excellent method to safeguard your investment and deter thieves who may be trying to steal your car for parts or to sell it.
In terms of their design laser-cut keys are different from mechanical cut keys in that they have fewer carved-out grooves on the key. They also have a thicker key shaft, which is a good indication that it's not your regular car key. Locksmiths typically use a machine called a milling tool to cut these types of keys. This machine is similar to a drill bit, and it's designed to remove metal with precise angles.
These are the most secure keys that you can purchase for your vehicle. They are difficult to duplicate and can only be done be cut by a certified locksmith or dealer. They're not like traditional keys. They're made from a small piece of steel that's shaped into a code and then cut with the laser in the factory. This kind of key is able to endure a lot of wear and tear, and is among the best choices for protecting your vehicle.
The key can be folded up into the fob, or be removed by pressing a button. Keys like this are used extensively in German automobiles and provide an additional layer of security against car thieves. They also make it very difficult for thieves to pick or pick-lock your vehicle, as the cylinder is extremely tough and difficult to break into.
Smart Keys
Smart keys communicate with the vehicle by using radio-frequency identification (RFID) instead of the traditional single piece carved metal. They are equipped with a chip that has an unique code that is encoded on each key. Whenever you unlock your car's doors, or open the trunk key, it sends a signal to the car's onboard computer. The computer then triggers the right frequency which allows you to open your car and begin it.
The chip inside the smart key has several security features to guard it from theft. The key emits an extremely low-frequency signal, which will only be detected by your car. If the computer onboard detects this signal, it will transmit a different one which is an exclusive code that only your car can understand. This stops a tech-savvy criminal from using a pulse generator to "fool the system" and perform the work on 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, and many 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.
Certain key fobs are opened by holding the dead key in a slot or by placing it in proximity to an inductive coil that is located on the dashboard. Some even come with an emergency (fully mechanical) key blade that is hidden inside the key to enable this.
Replacing a key with a smart chip usually requires a visit to the dealership, where they will either have the replacement on hand or purchase it for you. They'll also need to program the new key to recognize the car you are driving. But, you can visit a locksmith to have your replacement key fob programmed and replaced. Locksmiths will cost more than dealers, however, they can do the job faster and for less.
