Keys

Almost all modern cars require a transponder key or fob to operate, providing security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and the specific model. It's costly to replace them if they become lost, so it's best to have spares in your possession. You can locate key fobs that can be replaced in online stores as well as many brick and mortar auto shops. How can you be sure that the key you purchased is genuine? Do you know whether it has been programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle?

To program a new car key first make sure that your vehicle is running. Insert the key that you want to program into the ignition, but don't turn it. There are only a couple of seconds before the car's system resets the commands and then exits programming mode. This is why it is crucial to move fast and not wait between steps. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will go through a cycle.

Certain cars with more modern technology have rolling key system, which prevents thieves from using a stolen car's key to open it. This feature is still susceptible to a technique called replay attack. It allows thieves to record and later reproduce the signal received from the car key fob to open the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to thwart hacking attempts.

Certain manufacturers have a unique encryption on their keys that cannot be decoded using a simple program. These types of cars will need to be programmed by a professional, and you should only attempt this process if you have experience working with electronics. Check the manual of your car or visit the website of the manufacturer to find out how to program it. The steps will vary depending on the model of vehicle.

Transponder chips

Car keys with transponder chips require special reprogramming in order to work. While any hardware store can cut keys for you, the biggest problem is to make it work in conjunction with your particular car. A key that has been reprogrammed will need to be compatible with the exact identification number of the vehicle otherwise it won't even start the engine.

Transponder chips, used to stop theft of cars are a standard feature of modern automobiles. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car can detect the signal and begins the engine only if it matches the original one that was programmed in the vehicle. The car will also shut down if a frequency is not valid. This makes it more difficult for novice car thieves to hot wire a vehicle and then start it.

The chip and the key are connected via a circuit board that includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This generates a signal that gets amplified by the coil which sends it to the key's identification number. The key's identification number is transmitted back to the car and the engine is started when the identification number matches.

There are a few different ways to program a transponder key but they all involve using a special tool. You can purchase these tools online or from most locksmiths for cars. These tools are not inexpensive, but they are vital for programming your car's chip.

You could also use a resettable key that was programmed for another vehicle. In this case you'll need to make sure that the key isn't damaged or that the transponder has been altered in any way. You can read the chip with a scanner, or a computer with the USB connector.

Reprogramming the transponder key is simple, however it requires an expertly designed software and scan tool. It is best to consult an auto locksmith for help for those who are new to the process. Avoid buying used keys because they might already be programmed, and they won't work with your vehicle.
