Question 3

Which of the following best describes the difference between 'cloning' a transponder key and 'programming' a new key?

Accepted Answer

Cloning creates an exact copy of an existing key's electronic signature, making it indistinguishable to the vehicle, whereas programming adds a new, unique key to the vehicle's memory.
