Example One: When I put together the new lock on my door, I broke off a metal shaft inside the lock so it could only be engaged with a key. That way, I can never be
accidentally locked
out of the house. I told the workmen, "Don't worry about locking me out if I'm not here when you leave, I jerry-rigged the lock, you need a key to lock it".
Example Two: On
the drive home, my muffler was dragging on the asphalt. I jerry-rigged it with a piece of wire and gaffers tape so it would stay in place until I had it repaired.
