Nissan Xtrail 2003 automatic locks

Good folk friends, I have a consultation about the functionamineto of the automatic locks of the Nissan Xtrail 2003.

1. It is normal for the locks to be placed automatically after about 5 to ten minutes of being parked the car.

2 It is normal for locks while the automotive is placed insurance on the doors?

3. As configured the remote control or the automatic insurance system for destabilitation that insurance is placed in the ppuertas, reconciding that the remote control is separate, not integrated into the key of the key.

4. Why do you reason if you already change the battery of the remote control of the alarm and unlocking of the locks, this device stops working on the occasion.

5. If someone has the diagram of the Alarm and Unlocking Egurity System of the locks that comes from home to the Nissan Xtrail 2003, I would appreciate it.

Thank you very much for the discomfort.
