Peugeot 307 SW HDI, Air Bags and Central Locking?

The Air Bag and passenger air bag lights are on on my 2003 Peugeot 307 SW HDI. I have checked fuses and all seems ok.
Also have a problem with the central locking. Boot door is locked all the time but rest of doors do not lock either on the blip or with the key. Display shows both rear doors are open but this is not the case. Please help.
