Locks and Keys

Locks are almost the first thing to get lost or broken - if you can't get into that case please do not use a big screwdriver - you will only break something. Quite a lot of sewing machine cases can be opened with a small flat screwdriver to turn the lock; so try that, GENTLY, first. If the lock has a "keyhole" shape inside then your best bet may be a local antique dealer - they all have lots of odd wardrobe and box keys and may be able to find one that will do.
And NEVER, EVER carry the case by the handle, locked or not - the handle is to lift off the lid - otherwise you WILL break a toe... and probably the machine....
All the locks have been oiled and work...
