I've played with various picking techniques you mentioned, but didn't
want to advertise the fact. And as I said, I'm not very fast. I thought
rapping might be both inconspicuous and fast, but I couldn't make it work.
Do you recall the Master Lock model number? It will be on the bottom
plate. If it was a model that uses a dual ball bearing locking
mechanism, beating on it with a hammer will not work. Or, see if any
of these videos might have helped:

I have a 120V angle grinder, but the woman's shed was probably 100 feet
from any outlet. My "dremel" is actually a Black & Decker clone. I found
that its power transformer outputs DC voltage in the range of 12V (plus
or minus), so for portable use I long ago rigged up a plug to power the
tool from a surplus motorcycle battery I happen to have. That worked
well enough for this task.
The cordless Dremel hand tools are also 12VDC. Good idea, but I'm
lazy. I have a wooden box with a 12V 35AH(?) AGM battery, 117VAC
charger, 117VAC inverter, and various useful chargers. I keep wanting
to make or buy a LiIon replacement, but have never found an excuse to
spend the money. Maybe when the battery finally dies. The inverter
should run my 117VAC Dremel tools quite nicely.
Incidentally, most of my various gadgets (modem, router/wi-fi,
ethernet switch, Roku, media server, phone chargers, LiIon cell
chargers, small light, etc are running from an 11.1V LiIon battery
pack. If the power goes out, most everything stays up and running. No
UPS needed. I might use it (or a copy) as the basis for a replacement
Dremel power supply. Yet another project.
The biggest frustration was breaking then replacing a couple of the
fragile Dremel abrasive disks.
I know the feeling. It doesn't take much to break the little Dremel
cutting disk. But, the narrow kerf cut makes a few broken disks
worthwhile. Hint: Wear safety glasses.
