How do we get into the garage?

In this garage is my car and some furniture bought back by son R from Tewkesbury that needs some muscle to move it. This weekend  the running crowd from Edinburgh were supposed to earn their board by hauling some furniture upstairs. In particular a sofabed,  was going by rope up the outside and through a window because we could not get it up the stairs.  Imagine the scene this morning, its raining, our two strapping sons plus 3 strong friends are assembled outside ready for action.   We search the house, we cannot find the remote opener. M tries all the odd keys left by the previous owners but none fits the handle.   We phone Mr P on a day out by coach, he does not have the remote with him. He concludes  he has left the remote in the garage and closed the doors with the button on the wall. This means we cannot get into the garage. The strapping lads all left, disppointed not to be able to help us with the sofabed. I could not go out because my car is in the garage. Pretty p....d off actually. Not a wonderful picture but it certainly reminds me of my day
