Keys Replacement For Cars
If you own a basic mechanical key it is likely to get a replacement at any hardware store for relatively cheap. However, this key will have to be programmed by a locksmith or dealership.
Smart keys are more complicated and require a trip to the dealer to pair them with your vehicle. These types of keys are typically expensive, but some car insurance companies will cover the cost.
Mechanical Keys
You can still purchase mechanical car keys, the ones that you insert into the ignition lock cylinder to start your vehicle. 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 design an original key at a lower cost than what you purchase from a dealership. You can also have someone close to you who is proficient in programming transponder keys from the aftermarket (which are cheaper than factory keys) cut keys and have them programmed. It is essential to have a spare key since modern cars will not start if the key does not have the right 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 on the chip, but it will not start if you use another code.
If the spare key you have has chips it must be programmed by a dealer. They'll require a specific machine to cut the key and then program it. These machines are only available at certain dealerships, and it's unlikely that a locksmith has the equipment needed to create a laser-cut key with a transponder.
Keys with remotes can be costly to replace, especially when you require a spare. If you only have the key shank missing and a working replacement fob, you can try to reprogramme your fob by yourself. However, it can be time-consuming and complicated. If you've lost the entire key and fob, however you should seek out a dealer as the best option.
Other kinds of keys for cars require more specific skills to replace. These include flip keys as well as smart keys. These are more complex and typically need to be replaced at the dealership. Some key fobs feature an electronic key that folds into the enclosure and opens doors, or they're operated with proximity sensors to open and start your car.
Transponder Keys
If your car was built in the past 10 years or so, you're likely to use transponder keys. The keys have a microchip and a receiver that is programmed to send a signal to start your vehicle.
Transponder keys are an excellent way to discourage theft because they require two parts in order for the car to be started that 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 present, the car will not start and is impossible to connect hotwire.
Key chips have an individual serial number specific to your vehicle. When the key is inserted into the ignition the serial number is then sent to the immobilizer in the car and checked to ensure that it matches up, it will then allow the engine to start. This security feature is only defeated by a special device which can read the chip to match it with a different car.
When you get a transponder-related key replaced, you'll need to visit an authorized locksmith who has the equipment needed to reprogram the key into your vehicle. Some car dealerships offer this service, however their overhead makes them more expensive than an independent locksmith.
Finding a new car key that comes with a chip it is a complicated process. To program your car, the key has to be programmed on a special machine. It requires specialized software, as well as the appropriate key cutter to do it properly.
Some of the less complicated chip keys can be copied at most auto part stores, but you need to know the serial number of the original key to ensure the proper information is being programmed into the new key. Many people make the error of visiting a dealer to have their chip key copied and end in paying more than they have to.
Laser-Cut Keys
Laser-cut keys, referred to as sidewinder keys because of their distinctive winding cuts to the shank of the key, add an extra layer of security to your vehicle. These keys are a great security measure against theft of your vehicle because they require special equipment to duplicate.
Like transponder keys. They have built-in chips that block duplicate keys from getting into your car. They also typically have a unique code on the key, which must be programmed for your specific car in order to allow it to be opened and started. This extra layer of security is a great method to safeguard your investment and deter thieves who may be trying to steal your car for parts or to sell it.
Laser-cut keys differ slightly from mechanically-cut keys in terms of design. They have fewer grooves that are carved on the key. They also have a more robust key shaft that is an indication that it's not your typical car key. Locksmiths generally employ a machine known as a milling tool to cut these types of keys. This kind of machine appears much like a drill bit and is designed to remove metal at extremely precise controlled angles.
These are some of the most secure keys you can get for your car, as they're extremely difficult to duplicate and only cut by the dealer or a licensed locksmith. They're not like traditional keys. They're made from a small piece of steel that is shaped into a code and then cut using the laser in the factory. This type of key is able to endure a lot of wear and tear and is among the best choices for protecting your vehicle.
Depending on the key, it will fold in the fob or pop out with the click of a button. The keys are typically used in German cars and offer an additional layer of protection against car thieves. They also make it very difficult for thieves to pick your vehicle or pick-lock it since the cylinder is extremely tough and is difficult to break.
Smart Keys Keys
Smart keys communicate with the vehicle by using radio-frequency identification (RFID) instead of the conventional single piece of carved metal. They have a chip with a unique code, which is encoded on every key. Whenever you unlock your car's doors, or open the trunk, the key sends a signal to the car's onboard computer. The computer then will prompt the right frequency that allows you to start your car.
The chip in the smart key is equipped with several security features to protect it from theft. The key emits a low-frequency signal that can only be detected by your car. If the computer onboard detects this signal, it will transmit another one that is a unique code that only your car is able to understand. This prevents a tech savvy criminal from using a pulse generator to "fool the system" and make the key work on other vehicles.
Certain smart keys come with specific features, like storing driver preferences, opening windows remotely or the sunroof via remote, and many more. These can be done by activating the key fob's proximity sensor, pressing a button on the key or, in some cases, twisting a small metal component inside the key.
replace keys of these key fobs feature buttons that open the doors for themselves, but some have an additional method to open them with a slot or by placing the dead key near a spot on the dashboard where it holds an inductive coil that can transfer energy. Some even come with an emergency (fully mechanical) key blade concealed in the key to enable this.
To replace a smart key, you'll need visiting a dealer, where they can request the replacement or have it in stock. They'll also have to program the new key to recognize your vehicle. However, you can also go to a locksmith shop to have your replacement key fob programmed and replaced. Locksmiths will cost more than a dealer however, they can do the job faster and cheaper.
