When a key is placed into the ignition or brought within distance of a push-to-start button, the car sends out a signal to the transponder chip inside the key.

3. Cloning
Some older or easier transponder systems permit for "cloning." This is where the information from an existing working key is copied onto a blank chip. While efficient, it does not permit the deletion of lost secrets, as the car sees the clone and the initial as the exact same entity.
Do it yourself vs. Professional Services: The Risks and Rewards
