Reprogramming Car Keys
Transponder keys are thought to be more secure for cars and are more difficult to copy by thieves. Keys may need to be programmed again in the event of damage or lost.
You can change the programming of your key fobs at home, but you should know the right process. You must have these things to ensure the best results:
Keys
Most modern vehicles require a transponder fob or transponder keys to operate, ensuring security and protection against theft. The keys have to be programmed to your particular vehicle and its features by a licensed dealer or locksmith. It is expensive to replace them if they are lost, so it's a good idea to have spares available. You can find key fobs that can be replaced in online stores, as well as numerous brick-and-mortar auto shops. But how do you know that the new one you purchased is authentic? Can you tell if the unit has been programmed to work with a different vehicle, or if it can be programmed again?
If you are planning to program an entirely new key first, you need to ensure that your car is operating. Insert the key you wish to reprogramme into the ignition, but do not turn it. You have only a few seconds before the system resets all commands and exits the programming mode. Therefore, it is crucial to move fast and not pause between steps. To avoid this happening, shut off the engine. You can test the car's security system by turning the key to the "on" position, 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.
Some newer cars use a rolling key system, which prevents thieves from using a stolen car's key to start it. This feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and later duplicate the signal generated by the key fob of the vehicle to unlock the car. To combat this, manufacturers added the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also employ special encryption on their key fobs that cannot be decoded with an easy program. These types of vehicles will need to be programmed by a professional, so you should only attempt this procedure if you have experience working with electronic devices. Check the manual of your car or visit the website of the manufacturer for information on how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys with transponder chips require a special programming to function. While any hardware store can cut keys for you, the real challenge is making it function with your specific car. The key needs to be programmed to match the exact identification number on your car, otherwise it will not start.
Transponder chips, which are used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is put in the ignition. The car detects the signal, and starts the engine only if the signal matches the original one that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it harder for novice car thefts to hot-wire a vehicle and then turn it on.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is received by the coil and sent to the key's identification number. The ID number of the key is then sent back to the vehicle and if it is in line with the engine will start.
There are a variety of methods to program a key transponder, but all require a special tool. These tools are available on the internet or at most auto locksmiths. These tools aren't inexpensive, but they are vital for programming the chip in your car.
You can also use an reprogrammable key that was previously programmed for an alternative vehicle. In this scenario you'll need to make sure that the key has not been damaged or the transponder been altered in any way. You can read the chip by using a scanner or a computer equipped with an USB connector.
Reprogramming a transponder is a simple procedure, but requires specialized software. It also requires a scanner tool. It's best to ask an auto locksmith for help if you're a novice. Also, avoid buying second-hand keys, since they're probably already programmed and won't work with your car.
