Reprogramming Car Keys
Transponder keys are thought to be more secure for cars and are more difficult to copy by thieves. However, a key might need to be reset if it becomes damaged or lost.
You can reprogram key fobs yourself, but you must know the correct procedure. You must have these things to ensure the most effective results:
Keys
Almost all modern cars require some kind of transponder key or fob to work, which provides security and protection against theft. These keys must be programmed to your particular vehicle and its features by an authorized locksmith or dealer. It's costly to replace them if they're lost, so it's a good idea to keep extras on hand. You can find key fobs to replace them in online stores, as well as numerous brick-and-mortar auto shops. But how do you know that the new one you purchased is genuine? Can you tell whether the unit has been programmed to work with a different vehicle, or if it can be reprogrammed?
To program a new car key you must first verify that your vehicle is operating. Insert the key that you want to reprogramme into your ignition, but don't turn it. There are just a few minutes before the system will reset all commands and leaves the programming mode. For this reason, it is crucial to be quick and not pause between steps. To avoid this happening, shut off the engine. You can test the car's system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you will hear a chime to indicate that the process has been successful.
Certain newer vehicles have rolling key technology, which stops thieves from using stolen cars' key to start it. This technology is still vulnerable to a technique known as replay attacks that allows thieves to record the signal from the vehicle's key fob and reproduce it later to open the car. To stop this, manufacturers introduced the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys, which can't be decoded with an ordinary program. You should only attempt this process if your experience is with electronics. It is recommended to consult the owner's manual for your car or search for the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys with transponder chips require special reprogramming in order to work. Any hardware store can make you a new car key but the real challenge is in making it work with your car. A reprogrammed key will need to be compatible with the exact identification number of your car otherwise it won't even start the engine.
Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is put in the ignition. The car is able to detect the signal, and starts the engine only if the signal matches the one programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it more difficult for thieves who are not experienced to connect a vehicle with hot wires and start it.
The key and the chip are connected via a circuit board that includes an induction coil. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This produces a signal which is absorbed by the coil, which sends it to the key's identification number. The key's ID number is transmitted back to the vehicle, and if it is in line with the engine will start.
There are several ways to program a transponder key however, all require a special tool. You can buy these tools on the internet or at many locksmiths in the automotive industry. They're not cheap, but they're crucial for programming the chip in your vehicle.
You may also use a reprogrammable key that was previously programmed for a different vehicle. In this case you'll need to make sure that the key isn't damaged or the transponder been altered in any way. To accomplish this, you can use scanners or a computer with a USB port to scan the chip and determine its identity.
Reprogramming a transponder key is quite simple, however it requires an expertly designed software and scan tool. If you're just beginning, it's best to seek the assistance of an auto locksmith. Also, avoid buying secondhand keys, as they are likely already programmed and won't be compatible with your car.
EZ Installer
For a long time, car owners who needed to replace their key fob had no choice than to visit a dealership to have their key electronically linked to their vehicle. This is because in order for modern keys to function they have to be "paired". This required expensive and complex equipment that was available only to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys to vehicles for locksmiths and retailers.
The EZ Installer, a simple "plug-and-play" OBD device, pairs new keys with vehicles without the use of complicated equipment or tokens to facilitate programming. It connects directly to the standard OBD port of the vehicle and uses an application that is mobile that provides easy-to-follow instructions. The EZ Installer is compatible with all modern vehicles that include proximity keys or push-button start. Visit the compatibility guide on Tom's website to see if your vehicle is compatible.
If the device is unable to program a remote or a key purchased from Tom's into a vehicle compatible then a full refund is offered.
In contrast to traditional programming equipment that costs key professionals thousands of dollars with typical per-key "token" costs, the EZ Installer Pro doesn't charge these fees at all and can be used as long as a retailer or key professional would like to use it. The EZ Installer also eliminates the necessity for expensive monthly service contracts and updates, meaning that it could save retailers money while still providing customers with the same high-quality service as OEM equipment. It also comes with a world-class warranty that covers all hardware and software for the duration of its life.
Tools
Locksmiths, auto mechanics, and vehicle owners can use car key programming tools to program new keys for vehicles. These tools connect to a vehicle's immobilizer in order to program new keys and control them remotely. These tools can be used to make duplicates and make keys cloned. These tools are an essential tool for those who own a car.
