Transponder Clone Keys When a key for a car in the ignition is used it transmits a low-level radio signal (called transponder) to the chip. The signal is accompanied by a unique serial number which confirms that the key is the correct one for the vehicle. The system is designed to make it difficult to steal a vehicle because the vehicle will only begin to start when it receives the right signal from the correct key. Utilizing a 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 remove the data of the original key and a machine that can write that data onto another chip. Most conventional cloning devices work well with a variety of keys. However, some machines can be used with a small number of keys and brands. A cloning program that is reliable will not only determine whether or not there is a microchip in the key, but also what type of chip it is. This feature is important because there are so many varieties and brands of chips that are used today. When swapping the chips between the key shells, it is easy to mix them up, so the need for a cloning device able to distinguish between them is essential.

Key Fobs Key fobs can be used in a variety of applications. They are popular for access systems for apartment buildings and can also be used to control small home devices, like garage door openers. They make use of radio frequency identification, or RFID. When you press your fob against a reader, it transmits a specific frequency that can be recognized by the reader and permit access. These systems are typically monitored and controlled from a central computer system, so you can grant different levels of access to various individuals. You can also use the key fob to lock or unlock your vehicle. This is much safer than a traditional car key because it is not a risk that someone could copy the key. Plus, you can easily deactivate your key fob if it is stolen or lost, unlike a traditional key.

Fobs also help in preventing cyber attacks, that can be caused by lost or stolen keys that allow malicious actors with a key into a system to install malware or steal data, and also engage in other cybercrimes.
