The primary programmers are designed to communicate bidirectionally with your vehicle's OBD II connector. They are compatible with a variety of models and makes. Certain car manufacturers will not allow locksmiths in the area to reprogram keys to their vehicles, for security reasons. This will stop people from copying your existing key to steal your car.

These companies assume that their customers will be ignorant and will not be able to figure out how to accomplish things on their own. They make it more difficult for them to do so. Fortunately, most major US and Asian automakers have their key programming protocols with the tool makers that create and sell these types of devices.

Transponder Clone Keys When a car key is inserted into the ignition, it transmits an low-level radio signal to the transponder chip.

The system is designed to make it extremely difficult to steal a vehicle as the vehicle will only start once it receives the proper signal from the right key. Using an appropriate key cloning device allows you to duplicate keys without having to reprogram the car's computer to recognize the new key. Cloning keys to a car requires two things: a way to extract the data of the original key and a device that can transfer the data to a different chip. The majority of cloning devices are compatible well with a variety of keys. Certain machines, however only work with specific models and brands. A cloning software that is effective will not only tell you whether or not there is a microchip in the key but also which type of chip it is. This is essential because there are many different types and brands of chips used in the present.

They are commonly used in access control systems for apartment buildings and can also be used to control small household appliances like garage door openers. They use radio frequency identification, also known as RFID. When you press the fob on the reader, it emits a unique frequency that can be identified and allowed entry.

To program the key fob, you'll need an instrument that communicates with the vehicle's computer. Many locksmiths and auto technicians use a device known as the Smart Pro, which is a powerful tool for programming that can handle most major brands and models.
