Just bought a t reg peugeot 206 3 door. it has central locking but when i try to lock it, it opens again. It won't lock manually and the boot won't lock either. I don't really want to take to a garage as they are extortionate and i only bought the car for 800 What can i do?

My car does this occasionally. Try going round the doors and giving them a good slam shut then try and lock it again. I think the car thinks I still have a door open.
