20 Fun Facts About Reprogramming Car Key
Reprogramming Car Keys
Transponders in car keys are believed to make vehicles safer and are more difficult for thieves to duplicate. The key could need to be reprogrammed in event of damage or lost.
You can reprogram your key fobs at home, however you need to be aware of the proper procedure. 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 are programmed by a locksmith or authorized dealer to function with your car's systems and specific model. They can be costly to replace if lost therefore, you should have spares in your car. You can also find replacement keys fobs on various websites and in many brick-and-mortar auto shops. But how can you tell that the new one you purchased is authentic? Do you know if the unit has been programmed to work with a different vehicle or if yours can be programmed differently?
To program a new car key you must first verify that your vehicle is operating. Insert the key you want to reprogram into the ignition, but do not turn it. You will only have a few seconds before the car's system resets commands and then exits programming mode. For this reason, it is essential to move fast and not pause between steps. To prevent this from happening, turn off the engine. You can test the car's security system by turning the key to the "on" position and then back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will be able to cycle.
Certain newer vehicles have rolling key technology that keeps thieves from using a stolen vehicle's key to open it. This feature is still vulnerable to a technique known as replay attack which allows thieves to record the signal from the key fob on the vehicle and reproduce it later to unlock the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to thwart attacks on hacking.
Some manufacturers also use special encryption on their key fobs, that cannot be decoded with an ordinary program. You should only attempt this method if your previous experience is with electronics. Consult your car's manual or go to the manufacturer's website to find out how to program it. The steps to follow will differ depending on the model of vehicle.
Transponder chips
Car keys that feature transponder chips need special reconfiguration to work. While any hardware store can cut a new key for you, the biggest issue is how to integrate it in conjunction with your particular car. The key must be programmed to match the exact identification code on your car, or else it won't start.
Transponder chips are a typical feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is placed. The car then scans for the signal and then starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then turn it on.
A circuit board that has an induction coil connects the chip to the key. When the key is placed in the ignition it creates an electric field around the transponder. This creates a signal that is absorbed by the coil, which sends it to the key's identification number. The key's identification number is then sent back to the car and the engine will start if the identification number matches.
There are many methods to program a transponder keys, however, they all require 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 are vital for programming the chip into your car.
You may also use a unreprogrammable key that was programmed for an alternative vehicle. In this scenario, you'll need to make sure that the key has not been damaged or the transponder has been altered in any way. You can read the chip by using a scanner or a computer with a USB connector.
Reprogramming the transponder key is easy, but it will require an expertly designed software and scan tool. If you're new to the process you should seek the assistance of an auto locksmith. You should also avoid buying secondhand keys, as they are likely already programmed and won't work with your car.
EZ Installer
Prior to recently those who wanted to replace their key fob had to go to an agent to have it electronically paired with the vehicle. This is because, in order for modern keys to function they have to be "paired". This required expensive and complicated equipment that was only available to dealers. The EZ Installer from Car Keys Express solves this problem for locksmiths and retailers by easing the process of connecting modern keys to vehicles.
The EZ Installer, a simple "plug-and-play" OBD device, connects new keys to vehicles without the need for complicated equipment or tokens to facilitate programming. It works by connecting directly to the vehicle's standard OBD port and using an app for mobile devices to provide simple 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 website to see whether your vehicle is compatible.
A money-back guarantee of 100% is offered if the device does not successfully program a key or remote purchased from Tom's for a vehicle that is compatible.
Unlike traditional programming equipment that costs key professionals thousands of dollars in typical per-key "token" costs, the EZ Installer Pro doesn't charge any fees, so it can be used for as long as a key professional would like to keep it. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This lets retailers save money while offering 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.
