How to rectify the central locking on Vaux Zafira 07 Design 1.9cc model?

I was checking all the spade fuses for a fault on my windscreen washer in the fuse box locating in the boot and only realise afterwards it was in the engine compartment! Soon afterwards the remote on the key for locking the doors would not work.
I tried few things but it wont respond. What I do know is the boot will lock and unlock on the remote but not the 4 doors.
Tried both keys and same thing!
ould you plz help?
