Transponder keys are thought to be more secure for cars and harder to copy by thieves. The key could need to be reprogrammed in event of damage or lost.

You can reprogram key fobs yourself however, you must be aware of the correct procedure. You must have these things to achieve the best results:

Keys

Modern cars require a transponder key to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with your car's system and the specific model. They can be costly to replace if they are lost therefore, you should keep extras handy. You can also find replacement key fobs in various online stores and in many brick-and mortar auto shops. But how can you tell that the one you purchased is genuine? Do you know whether it was programmed to work with another vehicle or if it is able to be reprogrammed to fit your vehicle?

To program a new car key you must first verify that your vehicle is running. Insert the key you want to program into the ignition without turning it. You only have a few seconds before the car's system resets commands and leaves programming mode. It is crucial to move quickly and do not delay between each step. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. You should hear a sound to indicate that the process was successful. The door locks will be able to cycle.

Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the vehicle. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and duplicate the signal generated by the car key fob to open the car. To counter this, manufacturers have added a security feature called CAN bus protocol to prevent attacks on hacking.

Certain manufacturers also have special encryption on their key fobs, that cannot be decoded with a simple program. These types of cars will need to be programmed by a professional, and you should only attempt this process with someone who has experience with electronic devices. Consult your car's manual or visit the website of the manufacturer to find out how to program it. The steps are different depending on the model of vehicle.

Transponder chips

Car keys with transponder chips require a special reconfiguration to work. While any hardware store can cut a new key for you, the real problem is to make it work with your specific car. The key needs to be programmed to match the exact identification number on your vehicle, or else it will not start.

Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then detects the signal and then starts the engine if it matches the original frequency that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it harder for novice car thefts to wire a vehicle hot and then start it.

The key and the chip are linked by a circuit board that includes an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This creates a signal which is absorbed by the coil and sent to the key's identification. The ID number of the key is transmitted back to the vehicle and if it matches the engine will start.

There are a variety of methods to program a key transponder, but all require a special tool. You can purchase these tools online or at most automotive locksmiths. These tools are not inexpensive, but they are vital for programming the chip in your mobile car key programming.

You can also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this case, make sure that the key hasn't been damaged or the transponder isn't altered in any way. The chip can be read with a scanner, or a computer with the USB connector.

The process of reprogramming a transponder key is quite simple, however it requires specialized software and a scan tool. If you're a beginner you should seek help from an auto locksmith. Avoid buying used keys because they could already be programmed and won't work with your car.
