ABSTRACT:
The present invention teaches a method for preventing the use of an unauthorized reproduction of a remote unlock signal. In this scenario, the unauthorized reproduction occurs by jamming the receiver from receiving the remote unlock signal while intercepting the remote unlock signal. Generally, the remote unlock signal is transmitted by a transmitter to the receiver within a vehicle having a lock, wherein the receiver initiates an unlock command in response to receiving the transmitted remote unlock signal, and the vehicle lock being mechanically actuated by a key or electronically initiated by the unlock command in a previous locking session. The method for preventing the use of an unauthorized reproduction of a remote unlock signal comprises the steps of sensing whether the vehicle lock is being mechanically actuated by the key in the previous locking session, generating a flag if the vehicle lock has been mechanically actuated by the key, and disabling the receiver from initiating the unlock command in response to receiving the remote unlock signal transmitted by the transmitter if the flag is generated.
