Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. However, keys may need to be reprogrammed when it becomes damaged or lost.
You can reprogram your key fobs at home, but you should be aware of the proper procedure. For the best results, you'll need the following items:
Keys
Almost all modern cars require a transponder key or fob in order to operate, providing security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and the specific model. It's expensive to replace them if they become lost, so it's better to have spares available. You can purchase replacement key fobs in online stores as well as many brick-and mortar auto shops. But how can you tell that the one you have bought is authentic? Are you able to tell if it has been programmed to work with another vehicle or if it could be programmed to work with your car?
If you are planning to program an entirely new key the first step is to make sure that your car is running. Insert the key you'd like to reprogramme into the ignition, but do not turn it. You have only a few seconds left before the system will reset all commands and then exits the programming mode. It is crucial to move quickly and do not be patient between each step. To avoid this happening, shut off the engine. You can test the car's security system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you'll hear a sound that indicates that the procedure was successful.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the car. This feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and later reproduce the signal from the car key fob to open the car. To prevent this, manufacturers have added the security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded using an easy program. You should only attempt this method if your previous experiences are with electronics. Check the manual of your car or visit the website of the manufacturer to learn how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require a specific reprogramming to function. Any hardware store can make you a new car key, but the real challenge lies in integrating it with your car. The key you reprogrammed needs to match the specific identification number of the vehicle, or it won't start the engine.
Transponder chips are a typical feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is put into the ignition. The car then recognizes the signal and begins the engine if it is in line with the original signal that was programmed into the vehicle. The car is also programmed so that it will shut down if it detects an invalid frequency. This makes it more difficult for car thieves with no experience to connect a vehicle with hot wires and start it.
The key and the chip are connected via an electronic circuit board that contains an induction coil. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal that is taken up by the coil before being sent to the key identification number. The ID number of the key is then sent back to the vehicle, and if it matches the engine will start.
There are many ways to program a transponder keys, but they all involve using an appropriate tool. These tools can be purchased online or from most automotive locksmiths. They are not cheap, but they are essential for programming the chip to your vehicle.
You could also use a resettable key that was programmed for an alternative vehicle. In this instance you'll need sure that the key has not been damaged or the transponder been altered in any way. You can read the chip using a scanner, or a computer with an USB connector.
Reprogramming a transponder key is quite easy, but it will require specialized software and a scan tool. If you're just beginning, it's best to seek the assistance of an auto locksmith. You should also avoid buying secondhand keys, as they're likely to be programmed and won't be compatible with your car.
