and gate 12 and the nor gate 14 are being grounded by r1 and r2 with both inputs low the output of the and gate 12 is low and regardless of the electrical state of the bilateral gate bg1 there will be no voltage to trigger the one shot os l causing a low output and no base voltage to turn the transistor trl on whereby no locking of the vehicle 39 s doors will occur the nor gate 14 however with its inputs low will produce a high output state this high state could trigger one shot os u but since the bilateral gate bg2 is non conductive hi z state no voltage will reach the trigger input of the one shot os u and the same cascade effect of low output will not produce an unlocking ff is a jk flip flop set up to have q high and q 39 low at this stage of operation the flip flop ff is acting as an unlock disabler and a lock enabler once the key is in the ignition and is switched from the 34 ignition 34 or 34 on 34 position to a 34 start 34 position the and gate 12 will produce a high output that will trigger the one shot os l the output of the one shot os l will put enough voltage at the base of the transistor trl to turn it on and produce a locking of the doors.
