How Do You Reset a Slot Machine?
To reset a slot machine, open the service panel, locate the jackpot compartment, insert the jackpot key, and turn it slightly to the right. This 5-minute procedure requires the service panel key, the jackpot compartment key and a flashlight.
-
Open the service panel
Insert the slot machine service panel key into the lock on the side of the machine. Turn the key until the panel pops open.
-
Find the jackpot compartment and key
Locate the jackpot compartment, using a flashlight if necessary. If you do not already have the jackpot compartment key, examine the sides of the cash box. Most slot machine models have a plastic jackpot key sleeve on the side of the cash box.
-
Turn the jackpot compartment lock
Insert the key into the jackpot compartment. Slowly turn it one-quarter turn to the right. Do not turn the key further or attempt to turn it multiple times, because this causes most slot machines to enter calibration mode and renders them temporarily unplayable..
-
Close the machine
Return the key to its original position, take it out of the lock, and return it to the sleeve on the side of the cash box. Close the service panel, and verify that the machine is reset.
