English Mark Darts 5000 Stuck on Remove Darts?

[Minnesota]

Have an Arachnid English Mark Darts Machine that's stuck on Remove Darts.  Was wondering if anybody had any ideas on what might be needed for repairs.  Also, two additional questions what type of  key is needed to open up the rear cabinet? And assuming this board can be repaired I'd just like to sell it but have no idea what a unit like this might be worth.  Thanks in advance.

The factory shipped these machines with National Cabinet Lock key number C-415A. They continued using that key number all the way through the Super Six Plus 2 (a.k.a. 6300 series) dart games.

Thanks Ken appreciate the key type info.  After a few resets and a few more coins was able to get the dart board to work properly.  However, still trying to determine a fair price for this unit.  Do you have ideas what people are paying for these things?  Thank you.

The 5000 series is extremely old. I believe it came out around 1982. Don't know what the value would be in today's market.

Understand, Thanks Ken.
