As a new Zaf B owner and not having my manual infront of me, i've got to work and realised i have a slow puncture and would like to get sorted at lunch but i'm not sure how i get the spare wheel out from under the car?!

How do i access from inside??!!! Will the locking wheel nut key be there also as i have to say this isn't something i checked when i bought the car! Have checked under the car though and the wheel is there with a spanking new tyre

Thanks!!
