In this video I show you how to reattach the B and A keys when loose. This is a common occurrence and is usually due to vibrations from playing.

All you need to carry out this repair at home is a flat head 2mm wide screwdriver, but if you also have a spring hook to hand this will make the repair easier. If you don't have a spring hook you can use the tip of the screwdriver to push the springs into place.
