The complaint alleged that since 2011, Peppermill employee Ryan Tors had a slot machine "reset" key that allowed him to enter the slots in other competitors to determine the amount of hold — the amount kept by casinos on wagers.
On July 12, hotel security officers at the Grand Sierra Resort in Reno caught Tors using a reset key at their property. An investigation revealed that, beginning at least in 2011, Tors had used the reset key to obtain the information in 10 other casinos in the Reno-Sparks and Wendover areas.
Using a reset key to access information isn't illegal, but the Control Board intends to distribute an industry notice warning licensees not to use it in competitors' properties.
The complaint, drafted by Deputy Attorney General Michael Somps, said Peppermill's management instructed Tors "to use a slot machine reset key to access and obtain theoretical hold percentages information from slot machines belonging to one or more casinos that are competitors."
The second article posted by Merlin they suggest that the 2341 key shall be restricted from the general public. There are about a billion or so in the wild so I really can't see how they are going to restrict them. The only way would be to change the key switches - property by property,
If I was a lock smith I would be reaching out the casinos right now as they have a major compliance problem to deal with.
