Reprogramming Car Keys
Car keys with transponders are thought to keep vehicles more secure and more difficult for thieves to duplicate. However, a key might need to be reprogrammed if it becomes damaged or lost.
You can reprogram your key fobs at home, but you must know the right process. For the best results you'll need the following items:
Keys
Most modern cars require a transponder key to operate. This provides security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to function with the car's systems and the specific model. They are costly to replace if lost, so it is recommended to keep spare keys in the car. You can also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how can you tell that the new key fob you bought is authentic? Can you tell if the unit has been programmed to work with a different vehicle, or if it can be programmed again?
If you are planning to program an entirely new key the first step is to ensure that your vehicle is running. Insert the key you want to reprogram into the ignition without turning it. You have only a few seconds before the system resets all commands and exits the programming mode. This is why it is crucial to move quickly and not pause between steps. To prevent this from happening, shut off the engine. You can check the system of your car by turning the key to the "on" position and then back to the "off" position. You should hear a sound to indicate that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the vehicle. This feature is still susceptible to a technique called a replay attack. It allows thieves to record and then reproduce the signal received from the vehicle key fob to open the car. To stop this, manufacturers have added a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Certain manufacturers also employ special encryption on their key fobs that cannot be decoded with a simple program. You should only attempt this process if your experience is with electronics. It is a good idea to consult the owner's manual of your vehicle or look up the manufacturer on the internet, since these steps vary by vehicle type.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. While any hardware store can cut keys for you, the biggest challenge is making it function to work with the specific car you own. A reprogrammed key will need to be matched with the specific identification number of your car otherwise it won't even start the engine.
Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is put in the ignition. The car then detects the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is inserted into the ignition it creates a magnetic field around the transponder. This creates a signal which is absorbed by the coil and sent to the key's identification number. The key's identification code is sent back to the car and the engine is started when the identification number is in line with.
There are a variety of ways to program a transponder, but all require a special tool. You can buy these tools on the internet or at many automotive locksmiths. They are not cheap, but they are essential for programming the chip to your vehicle.
You may also use a reprogrammable key that was previously programmed for another vehicle. In this scenario, ensure that the key hasn't been damaged or that the transponder has not been altered in any way. To accomplish this, you'll need scanners or a computer with an USB port to read the chip and determine its identity.
Reprogramming the transponder is a straightforward procedure, but it requires specific software. It also requires a scanner tool. If you're a beginner you should seek out the help of an auto locksmith. Also, avoid buying second-hand keys, since they're probably already programmed and will not work with your car.
EZ Installer
Until recently, car owners who wanted to replace their keys were required to visit an authorized dealer to get it electronically linked to the vehicle. This is because modern keys need to be "paired" to the vehicle of the owner in order to function and work, which required the use of expensive and complex equipment that only dealers could access. The EZ Installer from Car Keys Express solves this issue for locksmiths and retailers by making it easier for connecting modern keys to vehicles.
The EZ Installer is a basic, "plug and play" OBD device that connects new keys to vehicles, without the need for expensive equipment or programming tokens. It connects directly to the standard OBD port on the vehicle and utilizes an app that can be downloaded on mobile devices to provide simple to follow instructions. The EZ Installer is compatible with most newer vehicles that include proximity keys or push button start. To see if it will work for a particular vehicle, look up the compatibility guide on the Tom's website.
If the device is unable to program the remote or key purchased from Tom's into a vehicle that is compatible then a full refund is provided.

It is able to be used for as long as a key professional or retailer requires. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This allows retailers to save money while offering their customers the same top quality service as OEM equipment.
