Reprogramming Car Keys
Transponders in car keys are thought to keep vehicles safer and are more difficult for thieves to duplicate. A key may have to be reprogrammed in case of damage or lost.
You can change the programming of your key fobs at home, but you need to know the right process. For the best results you must have the following items:
Keys
Most modern cars require a transponder key to operate. This gives security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to function with your car's system and the specific model. They are costly to replace if lost, so you should have spares in your car. You can find key fobs to replace them in online stores and many brick and mortar auto shops. But how do you know that the one you purchased is genuine? Can you tell whether it has been programmed for a different vehicle or if it could be reprogrammed for yours?
If you want to program a new key, the first step is to ensure that your vehicle is running. Insert the key you wish to reprogram into the ignition without turning it. There are only a few seconds before the system will reset all commands and exits the programming mode. It is important that you move quickly and don't delay between each step. Stop the engine to stop this. Switch the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will cycle.
Some newer cars use a rolling key system, which keeps thieves from using a stolen car's key to open it. This feature is still vulnerable to a method known as replay attack which allows thieves to record the signal of the key fob on the vehicle and reproduce it later to unlock the car. To prevent this, manufacturers have added a security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys that cannot be decoded by an easy program. You should only try this process if your experience is in electronic devices. Consult your car's manual or look up the manufacturer's website to learn how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys that feature transponder chips require special reconfiguration to work. While any hardware store can cut keys for you, the biggest issue is how to integrate it to work with the specific car you own. The key has to be programmed to match the exact identification code on your vehicle, or else it will not start.
Transponder chips, which are used to prevent car theft, are a common feature of modern automobiles. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car is able to detect the signal and begins the engine only if it matches the one programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it harder for novice car thefts to connect a vehicle to a hot wire and then turn it on.
A circuit board equipped with an induction coil that connects the key to the chip. 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 before being sent to the key identification number. The key's identification number is then returned to the car and the engine is started when the identification number matches.
There are a variety of methods to program a key transponder, but all of them require an instrument that is specifically designed for. These tools can be bought online or from most automotive locksmiths. They're not cheap, but they are vital for programming the chip to your car.
You can also make use of a transponder key that can be reprogrammed that was previously programmed for another vehicle. In this instance, you must make sure the key hasn't been damaged or that the transponder has not been altered in any way. The chip can be read with a scanner, or a computer equipped with an USB connector.
Reprogramming the transponder is a straightforward process, but requires specialized software. It also requires the use of a scanner. If you're just beginning you should seek out the help of an auto locksmith. Avoid buying used keys because they might already be programmed and won't be compatible with your vehicle.
EZ Installer
Prior to recently those who wanted to replace their key fob were forced to go to a dealer to have it digitally paired to the vehicle. It is because to make modern keys function, they need to be "paired". This required expensive and complex equipment that was available only to dealers. The EZ Installer from Car Keys Express solves this problem for retailers and locksmiths by easing the process of connecting modern keys to vehicles.
The EZ Installer is a simple, "plug and play" OBD device that connects new keys to vehicles, without the need for complicated equipment or programming tokens. It connects directly to the vehicle's standard OBD port and using a mobile app to provide simple-to-follow instructions. The EZ Installer works with a wide range of modern vehicles with proximity keys or push-button start. To determine if it'll work for a particular vehicle, look up the compatibility guide on Tom's website.
If the device fails to program a remote or a key purchased from Tom's into a compatible vehicle, a full refund is available.
Contrary to conventional programming equipment that costs key professionals thousands of dollars with typical per-key "token" costs, the EZ Installer Pro doesn't charge any fees which means it can be used as long as a retailer or key professional wishes it to be. The EZ Installer also eliminates the necessity for expensive monthly service contracts and updates, so it could save retailers money while providing the same quality service as OEM equipment. It also comes with a renowned warranty that covers hardware and software for the remainder of your life.
