Peugeot 306 N reg central locking problem

[NPeugeot]

Hi all, wondered if anyone could help me with my Peugeot 306 N reg Problem When i try to lock the doors with the remote on the key it locks and the opens again, i know that if i leave a door open it will do that, but i have checked that they are all closed, i noticed that the passenger rear door is making a different noise to the rest, even tho all the switches go down? Also i don't know if this is connected in anyway but when iv been in my car and pull up after sitting there for a few minutes, the radio turns it self off, and i have to rev the car to get it to come back on. These problems have only recently started.

Would be grateful for any help with this I'm a women and don't know anything about cars

thanks xx
