Keys Replacement For Cars
You can buy a replacement key for a mechanical one at any hardware store. However, the key will have to be programmed by a locksmith or dealership.
Smart keys are more complex and require a trip to the dealer to pair them with your vehicle. They can be expensive however, many insurance companies will cover the cost.
Mechanical Keys
There are still car keys that are only mechanical, such as the ones you place in an ignition lock cylinder and then turn to start your vehicle. If your car is equipped with one of these, replacing the key and fob is relatively cheap (if they get lost key replacement car or stolen).
A locksmith can cut a basic key for you at a less cost than what you would pay at a dealership. You can also ask a neighbour or a friend who knows how to program transponder keys (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 when a key that isn’t programmed with the proper chip is used.
Transponder keys look like mechanical keys, but they contain a hidden electronic chip inside the base of their plastic design that communicates with your vehicle’s computer system. Your car will recognize the code in the chip and accept it, but it will not start if any other code is used.
If the spare key you have has chip, you’ll need to bring it to a dealer to get it programmed. The dealership will need an equipment that is specifically designed for cutting and programming the key. These machines are only available at specific dealerships, and it’s not likely that a locksmith has the equipment needed to create a laser-cut key with a transponder.
Keys with remotes cost a lot to replace, especially if you need a spare. You could try reprogramming your fob yourself if you’re only missing the shank of the key and have a working replacement fob, however it can be time-consuming and laborious. You’re better off going to an expert if you’ve lost both the fob and the key.
There are other types of keys for cars that require a specialized set of skills to replace, such as flip keys and smart keys. These are more complicated and need to be replaced by the dealer. Some key fobs are operated by a proximity sensor or a door opener with a spring loaded mechanism.
Transponder Keys
Transponder keys are most likely to be used in cars built in the last 10 years. The keys are equipped with the microchip as well as the receiver is programmed to send a signal to start your car.
Transponder keys are a fantastic way to discourage theft because they require two parts for the car to be started which is the transmitter (transponder) in the key and the receiver connected to your immobilizer system. Without both the key and the immobilizer system being in place, the car won’t start and it will be impossible to hotwire.
These key chips have a unique serial number for your vehicle. When the key is inserted into your ignition, the serial number is transmitted to the cars immobilizer and checked to ensure that it is in line and allows the engine to run. The only thing that can defeat this security feature is a device that is able to detect the chip and match it to another vehicle.
You’ll need to find a locksmith that has the tools to reprogram your key. Some car dealerships also offer this service, but their overhead makes them more costly than an independent locksmith.
Finding a new car key with a chip inside it can be a complicated process. The key must first be cut using a particular machine to get the right tracks which can later be programmed to assign the key to your car. This requires specific software and the right key cutter to get it done properly.
Many auto parts stores are able to copy some of the less complicated keys for chips, but you’ll need to know the serial number of the original key to ensure the correct information is programmed into the key. Many people make a mistake by going to their dealer for a copy of a chip-key and end up paying overpriced prices.
Laser-Cut Keys
Laser-cut keys, also referred to as sidewinder keys because of their distinctive winding cuts in the key shank, add an extra layer of security to your vehicle. These keys are a great protection against auto theft since they require special equipment to duplicate.
Like transponder keys, they have built-in chips that block duplicate keys from opening your vehicle. They have a unique number that needs to be programmed into your vehicle to unlock it and begin it. This additional layer of security is a great method to safeguard your investment and deter thieves who could be trying to steal your car to make parts or sell it on.
Laser-cut keys differ from mechanically-cut keys in terms of design. They have fewer grooves that are carved on the key. The key shaft is also more substantial, which is another sign that this is not a regular car key. Generally, locksmiths use a machine called a milling tool to cut these kinds 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 among the most secure keys you can get for your car, because they are extremely difficult to duplicate and can only be cut by the locksmith who is a certified dealer. 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 type of key is able to endure a lot of wear and tear and is one of the best options to protect your vehicle.
The key can be folded up into the fob, or it can be released by pressing a button. These kinds of keys are commonly used in German cars and offer an additional layer of security against car key fobs and Remotes thieves. They also make it very difficult for thieves to pick your vehicle or pick-lock it because the cylinder is extremely rugged and hard to break into.
Smart Keys
Smart keys communicate with the vehicle via radio-frequency identification (RFID) instead of the traditional single piece of carved metal. This means that they are equipped with a tiny chip that contains an encrypted code that is unique to each key. The key transmits a message to the onboard computer of your vehicle each time you unlock the doors or open the trunk. The computer then will prompt the right frequency that allows you to start your car.
The chip in the smart key has several security features that protect it from theft. First the key emits a low-frequency signal that isn’t received by any other receiver, not even your car. If the computer onboard detects this signal, it will display an alternative one that’s a unique sequence that only your vehicle will recognize. This prevents a tech-savvy criminal from using an external pulse generator to “fool” the system and make the key work for other vehicles.
Some smart keys have specific features, like the ability to store preferences for drivers remote car key replacement opening windows, opening the sunroof from afar, and many more. These can be done by activating the key’s proximity sensor by pressing a button on the key itself or, in certain instances, twisting a small metal component inside the key.
Certain key fobs are opened by holding the dead key in a slot, or by placing it next to an inductive coil that is located on the dashboard. Some even include an emergency (fully mechanical) key blade concealed in the key to allow this.
Replacing a smart key typically requires a visit the dealership, who will either have the replacement on hand or purchase it for you. The dealer will also have to program your new key to identify your car. But, you can visit a locksmith to have your replacement key for car key fob programmed and replaced. Locksmiths will cost more than a dealer but they will do the job faster and cheaper.
