Keys Replacement For Cars
You can purchase a replacement key for a mechanical one at any hardware shop. The key must be programmed by a locksmith or dealer.
Smart keys are more complicated and require a visit to the dealer to pair them with your vehicle. These kinds of keys are usually expensive however some insurance companies will cover the cost.
Mechanical Keys
You can still purchase mechanical car keys which you insert into the ignition lock cylinder to start your vehicle. If your car uses one of these keys, it's inexpensive to replace the fob and key (if lost or stolen).
A locksmith can cut the basic key for you at a lower cost than what you would pay at the dealership. You can also ask a neighbor or friend who knows how to program transponder keys for aftermarket use (which are less expensive than factory keys) to make you a spare key and program it. Getting a spare is important since modern cars won't be able to start when a key that isn't programmed with the proper chip is used.
Transponder keys resemble mechanical keys but have an electronic chip hidden in the base. The chip communicates with the computer system in your vehicle. Your car will be able to recognize the code in the chip and accept it, however it will refuse to start if another code is used.
If your spare key contains chips, it will need to be programmed at a dealership. The dealership will require an equipment that is specifically designed for cutting and programming the key. The machines are available at specific dealerships, and it is unlikely that a locksmith would have the equipment necessary to create a key with a transponder.
It's costly to replace keys using remotes, especially if you require a spare. If you have just the key shank missing, and an operational replacement fob, you could try reprogramming your fob by yourself. However, it can be time-consuming and challenging. You're better off going to a dealer if you've lost both the fob and the key.
There are different kinds of car keys that require a more specialized set of skills to replace, like flip keys and smart keys. These are more complicated and need to be replaced by the dealer. Key fobs can be operated by proximity sensors or a door opener with a spring loaded mechanism.
Transponder Keys
Transponder keys will likely be used in cars built within the past 10 years. These keys contain an embedded microchip and a receiver that is programmed to send a signal to start your vehicle.
Transponder keys are a fantastic way to discourage theft because they require two components for the car to be able to start which is 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 the immobilizer system.
The key chips come with a unique serial number for your vehicle. When the key is inserted into your ignition, the serial number is sent to the cars immobilizer and verified that it is in line and allows the engine to run. The only thing that can stop this security feature is a device that is able to detect the chip and match it to another vehicle.
If you need a transponder-related key replaced you'll need to go to a locksmith that has the equipment needed to reprogram the key to your car. Some car dealerships provide this service, however they tend to be more expensive than an independent locksmith due to their expenses.
It isn't easy to get an original key that comes with a chip. To program your car, the key must be programmed on a special machine. This requires specific software and the right key cutter to get it done properly.
Certain of the more basic chip keys can be copied at a variety of auto parts stores, but you need to know the serial number of the original key to ensure the correct information is transferred to the new key. Many people make the mistake of going to their dealer in search of a copy of a chip key and end up paying overpriced prices.
Laser-Cut Keys
Laser-cut keys are also referred to as a sidewinder key due to the distinctive winding cut that is made on the key shank. They add an extra layer of security to your car. These keys are a great security measure against theft of your vehicle because they require specialized machinery to duplicate.
They also come with built-in chips that prevent the copying of keys by unauthorized people from starting your vehicle. They have a unique number that must be programmed into your car to unlock it and begin it. This extra layer of security is a great method to safeguard your investment and deter thieves who may be trying to steal your car to make parts or sell it to.
Laser-cut keys differ from mechanically cut keys in terms of design. They have fewer grooves carved out on the key. The key shaft is also thicker, which is another indication that this isn't an ordinary car key. Locksmiths usually employ a milling machine to cut these keys. This tool is similar to a drill bit and it's designed to remove metal in very precise angles.
They're among the most secure keys you can purchase for your car, because they're extremely difficult to duplicate and only cut by the dealer or a certified locksmith. They're not created using traditional keys. Instead, they are constructed from a small piece of steel that's shaped according into a specific code at the factory, and then cut with laser. This kind of key is able to be able to withstand a great deal of wear and tear and is one of the best choices for protecting your vehicle.
The key can be folded in the fob, or it can be removed by pressing a button. Keys like these are commonly used in German cars and offer an extra layer of security against car thieves. They also make it very difficult for a thief to pick your vehicle or pick-lock it since the cylinder is extremely tough and is difficult to break.
Smart Keys
Smart keys communicate with the vehicle using radio-frequency identification (RFID) instead of the traditional single piece of carved metal. They come with a chip with an unique code that is encoded on every key. The key transmits a message to the onboard computer in your vehicle every time you open the doors or open the trunk. The computer then will prompt the appropriate frequency to allow you to start your vehicle.
The chip of the smart key comes with a variety of security features to protect it from theft. First, the key emits a very low-frequency signal that isn't detected by any other receiver, not even your vehicle. If the computer onboard detects this signal it will send a different one which is a unique code that only your vehicle can comprehend. This prevents a tech savvy criminal from using an electronic pulse generator to "fool the system" and do the key work on other vehicles.
Some smart keys offer special features, such as saving preferences for drivers and opening windows remotely, or the sunroof remotely, and many more. These can be done by activating the key's proximity sensor, pressing a button on the key itself or, in some instances, twisting a small metal piece inside the key.
Most key fobs have an unlock button that opens the doors by themselves, but some have another method of opening them: a slot or holding the dead key in an area on the dashboard, where it is able to hold an inductive coil that can transfer energy. Some even come with an emergency (fully mechanical) key blade hidden in the key to allow this.
Replacing a smart lock requires an appointment with a dealer, who will either purchase the replacement or stock it. They'll also need to program the new key to recognize your car. You can also go to a locksmith for the replacement key fob to be programmed and replaced. A locksmith may cost more than dealers, but he or she can do the job quicker and for less.
