For transponder secrets and remote head keys, the authentication process takes place when the key is inserted into the ignition cylinder or, in push-to-start systems, when the key is brought within variety of the dashboard-mounted antenna. The car's ECU sends out a signal to the transponder chip, which responds with its special recognition code. Just after the ECU verifies this code does the vehicle'simmobilizer system enable fuel delivery and engine ignition.
Keyless entry systems depend on comparable principles, using rolling codes that change with each usage to avoid signal copying and unauthorized duplication. Each time the lock button is pushed, the remote sends a new code that the car's receiver expects, making it virtually difficult for burglars to tape-record and replay the signal to acquire entry.
