Transponders in car keys are thought to keep vehicles more secure and less likely to be duplicated by thieves. However, keys may need to be reprogrammed if it becomes damaged or lost.
You can change the programming of your key fobs at home, however you should be aware of the proper procedure. You must have these things to ensure the best results:
Keys
The majority of modern vehicles require a transponder keys to operate. This gives security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. It is expensive to replace them if they're lost, so it's best to keep extras on hand. You can purchase key fobs to replace them in online stores, as well as many brick-and mortar auto shops. But how can you tell that the key fob you bought is genuine? Do you know whether it was programmed for another car or if it could be programmed to work with your car?
If you are planning to program a new key the first step is to make sure that your car is on and running. Insert car key programmed wish to reprogram into the ignition without turning it. You will only have just a few seconds before the car's system resets commands and then exits programming mode. Therefore, it is essential to move quickly and not pause between steps. To avoid this happening, turn off the engine. Turn the key from "on" to "off" to test the system. There should be a chime indicating that the process was successful. The door locks will go through a cycle.
Certain cars with more modern technology have rolling key system, which stops thieves from using a stolen car's key to open it. The technology is still susceptible to a technique dubbed replay attack that allows thieves to record the signal of the key fob on the vehicle and reproduce it later to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to thwart hacking attempts.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded by an easy program. These types of vehicles require programming by a professional, so you should only attempt this procedure only if you've worked with electronic devices. It is recommended to read the owner's manual of your vehicle or look up the manufacturer online, as the steps will differ depending on the vehicle type.
Transponder chips
Transponder chip car keys require a special reprogramming to work. While any hardware store can cut keys for you, the main issue is how to integrate it in conjunction with your particular car. The key you reprogrammed needs to be matched with the specific identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a common feature in modern cars and are designed to stop car theft. 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 starts the engine only if the signal is in line with the original one that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it much harder for novice car thieves to hot wire a vehicle and start it.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is inserted into the ignition it creates a magnetic field around the transponder. This generates a signal, which is taken up by the coil and then transmitted to the key's identification number. The key's ID number is sent back to the vehicle and if it matches, the engine will start.
There are a few different methods to program a transponder key, however, they all require an instrument that is specifically designed for the purpose. These tools can be bought online or from most automotive locksmiths. These tools are not inexpensive, but they are vital for programming the chip in your car.
You can also use an reprogrammable key that was previously programmed for a different vehicle. In this case, make sure that the key isn't damaged or that the transponder is not altered in any way. You can read the chip with a scanner, or a computer equipped with the USB connector.
Reprogramming a transponder key is quite simple, but it requires special software and a scanning tool. It's best to ask an auto locksmith for help if you're a novice. Avoid buying used keys as they could already be programmed and will not work with your car.
