The 2007 Nissan Altima is fast, powerful and comfortable. As well as being customizable and user-friendly, there are numerous small touches that make it a polished and fun-to-drive machine. Sometimes those small touches can lead to customizations occurring accidentally. This is often the case when setting the lock options. In the 2007 Nissan Altima, the Intelligent Key controls whether the car beeps upon locking or not. The control can easily be switched to the "no beep" option when the key is thrust into a purse or back pocket.
Press the "Lock" button on your Nissan Ultima 2007 Intelligent Key remote. Be sure you are near your car, so you can listen for the beep upon locking.
Press and hold the "Lock" and "Unlock" buttons together. Wait at least two seconds. To confirm the horn has been reactivated, the hazard warning lights should flash three times.
Press the lock button to make sure the horn beeps once the car is locked. If not, repeat holding the "Lock" and "Unlock" buttons until the hazard warning lights flash.
