Anti-Scan Feature

To provide added security, the keypad is disabled for 1 minute after 36 button presses without a valid entry code being entered. The keypad flashes during this 1 minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.

Anti-scan turns off after 1 minute of keypad inactivity, the unlock button is pressed on a valid programmed RKE transmitter, a passive entry feature is used, or the ignition is turned on.
