The non-negotiable basics
Opening a game controller isn’t like fixing a toaster. The parts are small, the plastic is brittle, and the clips holding it together are designed to stay closed. If you sit down with a kitchen knife and a standard Phillips screwdriver, you are going to break something. You need a specific set of controller repair tools before you even think about unscrewing the first screw.
Most people damage their hardware within the first five minutes. It’s not a lack of skill. It’s a lack of leverage. A proper toolkit gives you the mechanical advantage needed to pop clips without shattering the housing and the precision to turn tiny screws without stripping the heads.
Precision screwdrivers: Not all are created equal
The screwdriver is the make-or-break tool here. Manufacturers like Nintendo and Sony use security screws to keep you out. A standard set from the hardware store won’t fit the head.
For the Nintendo Switch Pro Controller or Joy-Cons, you are looking at a Y00 tri-wing screwdriver. It looks like a Y-shape with three points. If you try to force a flathead into it, you will ruin the screw. Once that head is stripped, the repair becomes a nightmare of drilling and extraction.
The PS5 DualSense uses a standard Phillips, but it’s small. Usually a PH0 or PH00. The issue isn’t the shape. It’s the metal. Cheap bits are made of soft steel. You apply torque, the bit twists, and the screw cam-outs. You want a S2 steel or hardened steel bit. It bites into the metal and holds.
Magnetism matters too. These screws are tiny. If you drop one into the carpet, it’s gone. A magnetized shaft holds the screw in place while you align it with the hole. I usually run a magnet along the shaft of my screwdrivers before starting. It saves a lot of frustration.
Opening picks and plastic spudgers
Never use a metal pry tool to separate the controller shells. Metal scratches the plastic finish and can short out components if you slip. You need opening picks. These are usually thin pieces of plastic, sometimes made of POM or nylon.
The technique is simple. You insert the pick into the seam between the two halves. You slide it along the edge to disengage the plastic clips. It feels like a satisfying click. The pick flexes slightly, which absorbs the pressure. If you used a metal spudger, that pressure would crack the housing.
I keep a stack of these on my desk. They wear out. After a few repairs, the tip gets rounded or it snaps. That’s fine. They are cheap. Replacing a pick is better than replacing a $60 controller shell because you slipped with a knife.
When you are deep inside the case, moving ribbon cables or prying up batteries, a larger plastic spudger is useful. It’s thicker and gives you more leverage. You use it to push the battery away from the adhesive hold. Don’t pull it by the wires. You will rip the connector right off the board. Gently pry the battery up with the spudger until the adhesive lets go.
Tweezers and handling small parts
Once the case is open, you are dealing with parts the size of a fingernail. The screws that hold the motherboard down are often different lengths. Putting a long screw into a short hole can punch through the board and destroy a trace. You need tweezers to handle these safely.
I prefer non-magnetic, ESD-safe tweezers for handling electronics, but for screws, a pair of reverse tweezers is handy. They lock closed when you let go, holding the screw while you position it. Your fingers are too big and too oily for this work.
You also need a place to put the screws. A magnetic project mat is useful here. You can draw a diagram of the controller and place the screws in the corresponding spots as you remove them. It prevents the “leftover screw” panic when you are trying to put it back together.
Where cheap kits fail you
You will see 50-in-1 electronics repair kits for $15 online. They look tempting. They usually include a huge variety of bits you will never use and poor quality versions of the tools you actually need.
The plastic pry tools in these kits are often too thick. They won’t fit into the tight seam of a PS5 controller without forcing it. The screwdriver handle is usually round and slippery. When you encounter a tight screw, you can’t get enough grip to turn it without stripping it.
Invest in a dedicated kit. Look for one that specifically mentions precision screwdriver sets for consoles. Check if the opening picks are thin. A good kit costs a bit more, but it pays for itself the first time you successfully fix a drift issue without damaging the shell.
Cleaning and reassembly tools
The disassembly is only half the job. If you are opening the controller to clean it, you need the right media. Compressed air is okay for loose dust, but for the grime that builds up around the analog sticks, you need 90% isopropyl alcohol and a stiff brush.
Dip the brush in the alcohol. Scrub the gunk off the potentiometers. The alcohol evaporates quickly and won’t damage the electronics. Don’t use water. Water causes corrosion.
When you put it back together, check the button alignment. The silicone membranes often shift when you open the case. Make sure the buttons sit in their holes before you snap the shell shut. If a membrane is folded, the button won’t register. Press the buttons after you snap it together. If they feel mushy or stuck, open it back up and fix it. Don’t force it.
