Someone in another thread mentioned that they carry their airplane keys
all the time. I'd like to do that, but my 39 year old airplane has 3
different keys -- one for the baggage door, one for the cabin door and
one for the mag switch.

Has anyone successfully re-keyed an airplane back to a single key?

If the locks are made by the same company (unlikely), any locksmith can do that.
Remove the two door locks and see if a smith can rekey them to the that for the
master switch. If not, see if one of them can be rekeyed to the other (at least
you'd get down to two).

Me, I have a separate key for the door. I key both keys on a ring in my flight
case. If I were to want to be ready to fly anytime, I would keep the case in the
truck.
