Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, a key may need to be reprogrammed if it becomes damaged or lost.
You can program key fobs yourself but you must be aware of the correct procedure. For the best results you must have the following items:
Keys
Most modern vehicles require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. These keys must be programmed to the specific vehicle and its features by a licensed dealer or locksmith. They are expensive to replace in the event of loss, so it is recommended to keep spare keys in the car. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how can you tell that the one you purchased is authentic? Can you tell whether it has been programmed for a different vehicle or if it can be reprogrammed for yours?
If you're looking to program a new key first, you need to make sure that your car is running. Insert the key you wish to program into the ignition, but do not turn it. You have only a few seconds left before the system will reset all commands and leaves the programming mode. It is important that you move quickly and do not delay between each step. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful. The door locks will cycle.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique dubbed a replay attack which allows thieves to record the signal of the vehicle's key fob and then replicate it to open the car. To prevent this, manufacturers added the security feature known as the CAN bus protocols to prevent hacking.
Certain manufacturers employ a specific encryption on their keys, which can't be decoded with an easy program. It is best to only attempt this method if your previous experiences are with electronics. Refer to the manual for your car or look up the website of the manufacturer to learn how to program it. The steps are different depending on the type of vehicle.
Transponder chips
Transponder chip car keys require special reprogramming in order to function. While any hardware store can cut a new key for you, the real issue is how to integrate it with your specific car. The key must be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is put into the ignition. The car then recognizes the signal and begins the engine if it matches the original frequency that was programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then start it.
The key and the chip are connected via an electronic circuit board that contains an induction coil. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification number. The key's identification number is returned to the car and the engine will start when the identification number matches.
There are many ways to program a transponder, however all require an instrument that is specifically designed for. You can purchase these tools online or from most locksmiths for cars. They're not cheap, but they're vital for programming the chip in your car.
You can also use an resettable key that was programmed for an alternative vehicle. In this case you'll need sure that the key is not damaged or the transponder has been altered in any way. To do this, you'll need a scanner or a computer equipped with a USB port to identify the chip and establish its identity.
Reprogramming programming car key is easy, but it will require an expertly designed software and scan tool. If you're a beginner, it's best to seek out the help of an auto locksmith. Also, avoid buying second-hand keys as they're likely to be programmed and won't work with your car.
EZ Installer
For a long time, car owners who required replacement of their key fob had no other option than to go to a dealership to have their key connected to the vehicle. This is because modern keys need to be "paired" to a specific vehicle in order to work, which required the use of expensive and complicated equipment that only dealers could access. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys with vehicles for retailers and locksmiths.
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 runs a mobile application to provide easy to follow instructions. The EZ Installer works with most modern vehicles that include proximity keys or push-button start. To determine if it'll work with a specific vehicle, look up the compatibility guidelines on Tom's site.
If the device fails to program a remote or a key purchased from Tom's into a vehicle compatible, a full refund is available.
Contrary to conventional programming equipment which costs key retailers and professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It is able to be used as long as a key professional or retailer needs. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This allows retailers to save money while providing their customers the same high-quality service as OEM equipment. It also offers a top warranty that covers hardware and software for the remainder of your life.
