You can reprogram key fobs yourself however, you must be aware of the correct process. For the best results you should have the following items:

Keys

The majority of modern vehicles require a transponder key to operate. This provides security and anti-theft protection. These keys must be programmed to the specific car and its systems by a licensed dealer or locksmith. They are costly to replace in the event of loss, so you should have spares in your car. You will also find replacement key fobs at various online stores and in a variety of brick-and-mortar automotive shops. But how can you tell that the one you have bought is authentic? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be programmed differently?

To program a new car key, you must first ensure that your car is running. Insert the key you wish to reprogram into the ignition, but do not turn it. There are only a couple of seconds before the car's system resets commands and then exits programming mode. It is crucial to move quickly and do not wait between each step. Shut off the engine to prevent this. Turn the key from "on" to "off" to test the system. The door locks should cycle, and you'll hear a chime signalling that the process has been successful.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the car. The technology is still susceptible to a technique dubbed a replay attack which allows thieves to record the signal received from the key fob on the vehicle and reproduce it later to unlock the car. To counter this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.

Some manufacturers also use special encryption on their key fobs that cannot be decoded with an ordinary program. It is best to only attempt this method if you have experience is in electronic devices. Check the manual of your car or look up the manufacturer's website to find out how to program it.

Transponder chips are a common feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is put in. The car then detects the signal and then starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for novice car thieves to connect a vehicle with hot wires and start it.

A circuit board that has an induction coil connects the key to the chip. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal that is amplified by the coil which then transmits it to key's identification number. The key's ID number is then sent back to the vehicle and if it is in line with the engine will begin to run.
