[JOTSCS]

New user and just picked up an English Mark Darts 5000 (with NO keys) any help please?

Thanks to Ken Layton for info on rear / Rear Key Cabinet - National Cabinet Lock key number C-415A

In Search Of - info on front coin lock box - need key - any help or ideas? last resort is to drill out lock but that's no joy - would love to keep original OEM.

Thanks much

Solution - Key from Amazon C-415A was not correct - perhaps lock was changed out at some point.
on back lower wood tower, drilled 2" hole saw directly across from coin lock - with long screwdriver, unscrewed the bolt holding on the lock lever tab. and BINGO door open - and hanging inside was the key for the back upper panel. So cool! FYI key for back panel on this old machine is Fort Lock out of Chicago - blank #750 / cut # 1455.

Best wishes
