Hi,

I bought a second hand League Laser LG YAG 804B and a Han's Laser Phantom 1.These are quite old subsurface laser engraving machines. Unfortunately, the keys needed to activate and operate the machines are missing and without them the machines won't work.
I tried contacting Han's Laser but they say the Phantom 1 has been long discontinued and they don't have keys for them.

Where might I be able to find keys for these machines or is there a way to bypass them and operate the machines without keys?
