Call a locksmith, while I’ve not seen a Meyers, but my Cessna, my Maule and I’ve been told that Beechcraft all use desk locks, the kind you can get at a home improvement store, the little bar that actually locks may be modified though.
But a Locksmith should be able to extract the lock cylinder without damaging anything, or so I’ve been told.
A locksmith made new keys for the companies C-210, it didn’t come with keys. I think he just replaced the cylinder but I wasn’t there to watch.
