So you bought a used slot machine for your game room, or maybe you're managing a small casino floor, and the darn thing freezes or throws a code. Naturally, the first place you look is the key switch - except you can't find the key. It's rolled under the couch, got lost during the move, or the previous owner forgot to hand it over. Now you have a several-hundred-pound paperweight blinking error codes at you, and you need to know how to reset an IGT slot machine without a key without calling a technician or drilling out the lock.
Understanding the IGT Reset Lock Mechanism
IGT (International Game Technology) machines, particularly the popular S2000 model and the newer S3000 series, are built like tanks. They are designed for commercial casino environments where security is tight. The reset key switch is the primary interface for clearing jams, resetting hopper errors, and changing game settings. When you turn that key, you're toggling a physical switch inside the door that tells the machine's motherboard to interrupt its current state and listen for a command. If you don't have the key, you aren't locked out by software - you're locked out by a physical metal cylinder. The goal is to safely bypass that cylinder to trigger the switch behind it.
Before you start poking around, identify exactly what model you have. The S2000 is the most common home-use machine. The reset switch is typically located on the right side of the inside door, often near the top or middle, identifiable by the key cylinder face. On Video Poker machines or the slant-top styles, the location might vary, but the logic remains the same: you need to access the switch assembly behind the lock.
Safety Precautions Before Attempting a Reset
These machines run on electricity, and they hold heavy cash hoppers. Safety isn't just a buzzword here. First, turn off the main power switch usually located on the right side of the cabinet near the bottom, or simply unplug the machine from the wall. This prevents accidental short circuits if your tool slips. Second, be aware that the door lock itself is often the only thing securing your machine. If you force the mechanism, you might damage the lock so it never works again, even if you find the key later. Proceed with the understanding that you are modifying the hardware.
Accessing the Machine Internally
Here is the part most guides gloss over: getting inside. If you have a jammed door and no key, you can't open the machine to reach the reset switch. However, most owners asking this question have the door already open but lack the specific reset key for the settings switch. Let's assume the door is open. Open the main glass door and locate the reset key cylinder. You will see a metal bracket holding the switch assembly. You don't need to pick the lock. You need to remove the assembly.
Look for the two screws holding the lock nut and switch bracket to the inside of the door. Remove these screws. This allows you to pull the entire switch assembly into the cabinet. You don't need to cut wires. Once the assembly is free, you will see the micro-switch that the key cylinder is supposed to toggle. You can manually press this switch to perform the reset.
The 'Jumping the Switch' Method
If you are comfortable with basic electronics, this is the most effective way to reset an IGT slot machine without a key permanently available. Trace the wires from the reset switch to the connector on the motherboard or use. You can unplug this connector. By connecting the two wires (usually a simple loop), you simulate the 'key turn' signal to the CPU.
However, for a quick fix, just manipulating the micro-switch is safer. Locate the small plastic nub on the switch - this is what the key mechanism pushes against. Press it once. If the machine was frozen, this acts as a soft reset. If you are trying to clear a specific code, you might need to hold the button while powering the machine on. This forces the machine into a reset state, allowing you to clear RAM errors or hopper jams using the buttons on the door.
Drilling the Lock (The Last Resort)
If your machine door is locked shut and you have zero access, you have a different problem. You cannot reset the machine software without getting inside first. In this scenario, you may need to drill the lock. Use a drill bit slightly smaller than the key cylinder. Drill directly into the center of the keyhole. Apply steady pressure. You are trying to shear the pins inside the cylinder. Once the pins break, you can usually insert a screwdriver and turn the lock mechanism as if you had a key. This destroys the lock, meaning you will need to buy a replacement lock cylinder (standard Cam locks fit many IGT cabinets) after you regain entry.
Clearing Specific Error Codes
Once you have managed to trigger the reset switch, you need to know what to do next. Different codes require different sequences. For instance, a '61' error on an S2000 usually points to a coin comparator issue or a RAM clear requirement. After triggering the reset switch, the display will prompt you. On older machines, you use the spin button or the 'Bet' buttons to toggle through options. If you see a 'Call Attendant' message, holding the reset switch for five seconds often clears it, provided the physical issue (like a jammed coin) has been resolved.
Common codes you might need to reset include:
- Code 3100: Hopper empty or jam. Clear the jam manually in the hopper, then trip the reset switch.
- Code 3300: Bill validator issue. Open the validator door, remove the jam, and reset.
- RAM Error: This requires a full clear. You usually need to hold the white test button on the motherboard while tripping the reset switch to enter the setup menu.
Replacing the Lock Cylinder
After successfully resetting the machine, you probably don't want to go through this hassle again. Replacing the lock cylinder is cheap and easy. Once you have the old lock drilled or removed (by unscrewing the retaining nut from the inside), take measurements. Most IGT machines use a standard tubular lock or a flat tumbler lock. You can find replacements online for under $20. When installing the new one, ensure the 'cam' on the back of the lock aligns with the switch mechanism so that turning the new key actually presses the switch. Test it before screwing everything back together.
FAQ
Can I reset an IGT slot machine with a generic key?
Most IGT machines use a specific tubular key, often Code 61 or 72 for home models, but many 'universal' slot keys available online can open older S2000 models because they were mass-produced with similar lock codes. Buying a universal key set is usually cheaper and less destructive than drilling the lock or modifying the switch wiring.
Does turning off the power reset the machine?
No, simply unplugging the machine will not clear error codes or reset the software logic in most IGT machines. These machines are designed to retain RAM memory even when unplugged to preserve game state and accounting data. You must trigger the physical reset switch or clear the RAM via the motherboard jumper to reset errors.
Where is the reset switch located on an IGT S2000?
On the IGT S2000 upright cabinet, the reset key switch is located on the inside of the main door, usually on the right-hand side. It is a metal cylinder face with a switch assembly screwed to the back of it. If you are looking at the open door, it is often near the reel bundle or the top glass area.
Will resetting the machine erase my game settings?
It depends on the type of reset. A standard reset (turning the key switch) usually just clears errors and allows the machine to resume play. However, a 'RAM Clear' - which involves holding the test button on the motherboard while resetting - will wipe all settings, including denomination, volume, and paytable percentages, returning the machine to factory defaults. You should only do a RAM clear if you have the setup instructions for your specific game chip.
