Reprogramming Car Keys
Transponder keys are said to be more secure for cars and are more difficult to copy by thieves. The key could need to be reprogrammed in the event that it is damaged or lost.
You can reprogram key fobs yourself but you must be aware of the proper procedure. For the best results you'll need the following items:
Keys
Most modern vehicles require some kind of transponder key or fob in order to work, which provides security and anti-theft protection. These keys must be programmed to your particular vehicle and its systems by a licensed dealer or locksmith. They can be costly to replace if lost therefore, you should keep extras handy. You can also find replacement key fobs in various online stores and in many brick-and-mortar auto shops. How do you ensure that the new one you purchased is genuine? Can you tell whether the unit is programmed to work with a different vehicle or if it could be programmed again?
To program a new car keys, first make sure that your vehicle is running. Insert the key you wish to reprogram into the ignition without turning it. You only have a few seconds before the car's system reverts the commands and then exits programming mode. For this reason, it is important to move quickly and not be able to wait between steps. Shut off the engine to prevent this. Turn the key from "on" to "off" to test the system. The door locks should be able to cycle, and you will hear a chime to indicate that the procedure was successful.
Some newer vehicles use rolling keys to keep thieves from using stolen keys to start the car. The feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and later reproduce the signal received from the vehicle key fob to open the car. To prevent this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.
Some manufacturers also use special encryption on their key fobs which are not decoded by an ordinary program. These kinds of cars will need to be programmed by a professional. Therefore, you should only attempt this procedure with someone who has experience with electronic devices. Refer to the manual for your car or look up the manufacturer's website to learn how to program it. The steps to follow will differ according to the type of vehicle.
Transponder chips
Transponder chip car keys require a specific reprogramming to work. Any hardware store can offer you an entirely new car key, but the real challenge lies in integrating it with your car. The key needs to be programmed to match the exact identification number on your vehicle, or else it won't be able to start.
Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is put into the ignition. The car then recognizes the signal and starts the engine if it matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it difficult for novice car thefts to wire a vehicle hot and then start it.
The chip and the key are connected via a circuit board that includes an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal that is absorbed by the coil before being sent to the key's identification. The key's identification number is transmitted back to the car and the engine is started when the identification number is in line with.
There are several methods to program a transponder key, but they all involve using an instrument that is specifically designed for the purpose. These tools are available on the internet or at most auto locksmiths. They are not cheap, but they're vital for programming the chip into your car.
You could also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this instance you'll need sure that the key isn't damaged or the transponder has been altered in any way. To do this, you'll need scanners or a computer equipped with an USB port to identify the chip and establish its identity.
Reprogramming an transponder's key is easy, but it will require special software and a scanning tool. If you're a beginner it is recommended to seek help from an auto locksmith. Also, avoid buying second-hand keys, since they're probably already programmed and will not work with your vehicle.
EZ Installer
In the past the time when car owners wanted to replace their keys were required to go to an agent to have it electronically paired with the vehicle. It is because to make modern keys function they must be "paired". This required expensive and complicated equipment that was available only to dealers. The EZ Installer from Car Keys Express solves this problem for locksmiths and retailers by simplifying the process of pairing modern keys with vehicles.
The EZ Installer, a basic "plug-and-play" OBD device, pairs new keys with vehicles without the use of complicated equipment or tokens to facilitate programming. It works by connecting directly to the vehicle's standard OBD port, and then using a mobile app to provide easy-to-follow instructions. The EZ Installer works with most modern vehicles that include proximity keys or push-button start. Go to the compatibility guide on Tom's site to see whether your vehicle is compatible.
If the device fails to program a remote or key purchased from Tom's into a compatible vehicle the full refund will be provided.
Unlike traditional programming equipment, which costs retailers and key professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these fees. It is able to be used as long as a key professional or retailer requires. The EZ Installer also eliminates the need for costly monthly service contracts and updates, meaning that it could save retailers money while still providing the same quality service as OEM equipment. It also offers a leading warranty that covers both hardware and software for the rest of your life.
