LK201 and LK401 are (from the software point of view) mostly identical.
In fact, after a LK401 powers on, it's in LK201 mode and won't actually
send scancodes for the additional key(s) until it's switched to LK401
mode. So I guess you'd even use a LK201 to fix your password.. LK[24]01
keyboards are somewhat "common" on ePay, should be easy to get one
there if you cannot find another source.

If you cannot find one _at_all_, I'd probably write you a small emulator
for this keyboard to be used with any other machine which features a
serial port...
