How do i perform the 2007 Nissan Altima anti theft system reset?

First, let's go over how the 2007 Nissan Altima's anti-theft system functions. When the ignition switch is in the OFF position, this is known as the initial position. If You open the door or the trunk, the vehicle security system is then in the disarmed phase, because it's assumed the owner is inside or near the car. When in this state, the security indicator lamp will blink every two to four seconds. When You lock the door, after all the doors and trunk is closed, the onboard computer receives a signal and puts the system into the pre-armed phases. The security indicator now will illuminate for 30 seconds, and the system goes to the armed phase. So, how do You get out of it Well, You can unlock the doors with the key or key FOB. You can also turn the ignition switch to the ON or ACC position. Either of these cancel the alarm. To check if the system's armed, which will result in the system sounding the horn and flashing the headlights for around 50 seconds, You can open the trunk or any door while the system is armed, or by disconnecting and connecting the battery (without having cancelled the armed phase) To fully reset the system, just put Your intelligent key in the ignition, turn to ACC position for around 10 minutes, turn to the OFF position, and then start the car.
