Alarm Problem

[Rachael1994]

Hi, Newbie here.

I have a 2013 plate Renault Megane 1.5 DCi and have had it for 2 years. About 2 weeks ago I started to have a problem, the alarm started going off when I opened the driver side door.
Another fault I seem to be having is that when I unlock the car and open my drivers door, it door will lock, but all of the other doors (boot included) stay unlocked. Even when I lock and unlock the car with the fob, the drivers door will still not open. So I have to climb through and open the drivers door from the inside.
Has anyone else had this fault?

Thank you for taking the time to read this.
Rachael.
