Reprogramming Car Keys
Transponder keys for car keys are thought to keep vehicles more secure and harder for thieves to duplicate. However, a key might need to be reprogrammed when it becomes damaged or lost.
You can reprogram your key fobs at home, however you need to know the right process. For the best results you'll need the following items:
Keys
Nearly all modern vehicles require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. The keys have to be programmed to the specific car and its systems by an authorized dealer or locksmith. They are expensive to replace if lost and you should have spares in your car. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. How can you know that the key you purchased is genuine? Do you know whether it was programmed for a different vehicle or if it is able to be programmed to work with your car?
To program a new car keys, you must first ensure that your vehicle is running. Insert the key that you'd like to reprogramme into the ignition, but don't turn it. You only have a couple of seconds before the car's system resets the commands and exits programming mode. It is crucial to move quickly and do not be patient between each step. Stop the engine to prevent this. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle and you will hear a chime signalling that the process has been successful.
Certain newer vehicles have rolling key system, which keeps thieves from using a stolen car's key to open it. This technology is still vulnerable to a technique known as a replay attack which allows thieves to record the signal received from the key fob on the vehicle, then reproduce it to open the car. To stop this, manufacturers added security features known as the CAN bus protocols to prevent hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded using an ordinary program. It is best to only attempt this method if your previous experiences are with electronic devices. Check the manual of your car or look up the manufacturer's website to find out how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. Any hardware store can offer you a new car key but the real challenge is in implementing it to your vehicle. The key has to be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips are a typical feature of modern automobiles and are designed to prevent car theft. The chip is a microcircuit that emits a radio frequency signal when the key is put into the ignition. The car detects the signal and begins the engine only if the signal is in line with the original one that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it much more difficult for thieves who are not experienced to hot wire a vehicle and start it.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is put in the ignition, a magnetic field is created around the transponder. This creates a signal that gets absorbed by the coil, which then transmits it to key's identification number. The key's identification number is then transmitted back to the car and the engine will start if the identification number matches.
There are several ways to program a transponder keys, but they all involve using a special tool. These tools can be bought through the internet or from many automotive locksmiths. These tools aren't expensive, but they are essential for programming your car's chip.
You could also use a unreprogrammable key that was programmed for an alternative vehicle. In this case, make sure the key isn't damaged or the transponder isn't altered in any way. The chip can be read with a scanner, or a computer with an USB connector.
Reprogramming an transponder is a simple procedure, but it requires specific software. It also requires a scanner tool. If you're just beginning it is recommended to seek out the help of an auto locksmith. Don't buy used keys since they could already be programmed and will not work with your car.
EZ Installer
In the past those who wanted to replace their key fob were forced to visit an agent to have it electronically linked to the vehicle. This is because modern keys have 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 by Car Keys Express simplifies the process of pairing modern keys to vehicles for retailers and locksmiths.
The EZ Installer, a basic "plug-and-play" OBD device, connects new keys to vehicles without the use of complex equipment or tokens for programming. It connects directly to the standard OBD port on the vehicle and uses an application that is mobile to provide easy to follow instructions. The EZ Installer works with a wide range of modern vehicles with 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 My Page fails to program a remote or key purchased from Tom's into a vehicle that is compatible, a full refund is provided.
In contrast to traditional programming equipment that can cost retailers and key professionals thousands of dollars in typical per-key "token" charges, the EZ Installer Pro doesn't charge any fees and can be used as long as a key professional wishes to keep it. The EZ Installer also eliminates the need for costly monthly service contracts and updates, meaning that it can save retailers money while providing customers with the same high-quality service as OEM equipment. It also comes with a renowned warranty that covers hardware and software for the duration of your life.
