What Tools You Actually Need for a Joy-Con Shell Swap (and What You Don’t)

Before my first Joy-Con shell swap, I almost bought a $45 “professional electronics repair toolkit” with 48 different bits, anti-static mats, magnifying lamps, and a bunch of tools I still can’t identify. I’m glad I didn’t. The reality is that a Joy-Con shell swap requires maybe three or four tools, and most of them come included in a decent shell kit. The rest is either unnecessary or situational enough that you shouldn’t buy it until you specifically need it.

I’ve done enough swaps now to know exactly what earns its place on the desk and what stays in the drawer. Here’s the honest breakdown.

The Essentials: You Cannot Skip These

Y00 Tri-Wing Screwdriver

This is the single most important tool for the entire project. Joy-Cons use Y-type tri-wing screws on the exterior shell, and they require a Y00 driver. Not Y0. Not Y1. The Y00 designation refers to a specific size, and using the wrong one will strip the screw heads almost immediately.

The tri-wing screws on Joy-Cons are made of soft metal. They’re not designed for repeated removal — Nintendo uses them partly as tamper deterrents. A properly sized Y00 driver seats firmly in the screw head and turns with minimal effort. A slightly oversized driver will slip, round the edges of the Y-shaped recess, and leave you with a stripped screw that’s incredibly annoying to extract.

Most mid-range shell kits include a Y00 driver. Before you start the swap, test the included driver on one of the screws. It should drop into the recess and feel snug. If it wobbles or you have to push hard to get it to engage, the driver is either the wrong size or poor quality. In that case, buy a standalone Y00 driver — they’re $3-5 and worth every cent.

Phillips #00 Screwdriver

The internal screws inside a Joy-Con are standard Phillips head, and they use the #00 size. These screws hold the midframe and internal brackets in place. They’re small but they’re better quality than the exterior tri-wing screws, so stripping is less of a concern.

Again, most kits include this. The included one is usually fine. If you already own a precision screwdriver set, check if you have a #00 Phillips — it’s a common size in electronics work.

Plastic Spudger

A spudger is a flat prying tool used to disconnect ribbon cable connectors and separate shell halves. The key word is plastic. You need a non-conductive, non-scratching tool for working around circuit boards. Metal tools can scratch traces on the PCB, short components, or damage the delicate locking tabs on ribbon cable connectors.

A basic plastic spudger — the kind that comes in most shell kits — works perfectly. It doesn’t need to be fancy. One flat end for prying open connectors, one pointed end for lifting cables. If your kit doesn’t include one, a guitar pick works in a pinch for separating shell halves, though a proper spudger is better for the connector work.

Nice to Have: Makes the Job Easier

Magnetic Mat or Screw Tray

A Joy-Con has roughly a dozen screws of two different types, plus small springs and clips. Keeping them organized matters, especially when some screws are different lengths and go back in specific positions. A magnetic mat holds screws in place so they don’t roll away, and you can even label zones to remember which screw came from where.

I started using a magnetic mat after my second build, and it noticeably reduced reassembly confusion. Before that, I used a piece of tape sticky-side-up on the desk, pressing each screw onto it as I removed it. That works too — it’s just less elegant.

If you don’t have a magnetic mat and don’t want to buy one, a small bowl or an egg carton also works for keeping screws from escaping. The point is: have a system. Loose screws on a desk will end up on the floor, under the couch, or inside the cat.

Tweezers

Fine-point tweezers are helpful for handling the trigger springs, positioning small ribbon cables, and placing button membranes accurately. You can do the job without them — I did my first two swaps barehanded — but tweezers give you more precision with the fiddliest parts.

I use a pair of angled ESD-safe tweezers now. They were about $4 and they’ve made the spring handling significantly less stressful. Not essential, but a nice quality-of-life upgrade if you plan to do more than one build.

Good Lighting

This sounds obvious, but it matters more than people expect. Joy-Con internals are small and dark-colored. The difference between the two types of screws can be hard to see in dim light. Ribbon cable connector locking tabs are tiny and need good visibility to operate correctly.

I work under a desk lamp angled to illuminate the workspace directly. Any focused light source works — even a phone flashlight propped up nearby. The point is to avoid working in ambient room light where shadows hide important details.

What You Don’t Need

Heat Gun

I see this on recommended tool lists for shell swaps and it confuses me every time. Joy-Con shell swaps do not require heat. There is no adhesive holding Joy-Con shells together — they’re screw-and-clip assemblies. You unscrew them and they come apart.

A heat gun is needed for front frame console body swaps, where the frame is adhered to the screen with thermal adhesive. But that’s a completely different procedure that most beginners shouldn’t be doing. For a Joy-Con swap, leave the heat gun in the closet.

Soldering Iron

Unless you’ve torn a ribbon cable off its connector and need to reattach it — which shouldn’t happen if you’re careful — there is zero soldering involved in a shell swap. You’re not modifying any electronics. You’re just moving them from one housing to another. All connections are plug-and-play ribbon cables and snap-in connectors.

If you see a tutorial that mentions soldering for a basic Joy-Con shell swap, that tutorial is either covering an advanced modification (like LED installation) or it’s confused about what a shell swap involves.

Anti-Static Wrist Strap

I know this is going to bother the electronics purists, but I’ve never used one during a shell swap and I’ve never had a static discharge issue. Joy-Con components are reasonably robust against the kind of static you’d encounter in a normal indoor environment. If you’re working on carpet in the middle of winter with wool socks and a fleece jacket, maybe take precautions. Otherwise, just touch a grounded metal object before you start and you’ll be fine.

That said, if you already own one, wearing it doesn’t hurt. I just wouldn’t buy one specifically for shell swaps.

Specialized Multi-Bit Toolkit

Those big kits with 30+ bits look impressive, but for Joy-Con work you need exactly two: Y00 tri-wing and #00 Phillips. The other 28 bits will sit in the case forever. If the kit-included screwdrivers work, you don’t need anything else. If they don’t, two individual quality drivers are cheaper and better than a massive kit full of sizes you’ll never use.

What About the Tools That Come in Shell Kits?

Most shell kits from brands like eXtremeRate include a small tool set: a Y00 driver, a Phillips driver, a plastic spudger, and sometimes tweezers. In my experience, these included tools range from “perfectly adequate” to “functional but not great.”

The included Y00 driver is the one to watch. If it’s good, use it. If it feels loose in the screw head, replace it immediately — don’t try to power through with a bad driver. The included Phillips and spudger are almost always fine. I’ve never had a problem with a kit-included Phillips #00.

My recommendation for beginners: start with the kit-included tools. If the Y00 driver works, great — you’ve spent $0 extra. If it doesn’t, buy a single standalone Y00 driver for a few bucks. Don’t preemptively buy a $20 precision driver set before you’ve even tested what comes in the kit.

My Current Setup After Many Builds

For reference, here’s what I actually use now after doing many shell swaps. This isn’t what I recommend for a beginner — it’s what I’ve gradually accumulated because I do this regularly:

A quality standalone Y00 driver with a comfortable grip. A #00 Phillips from the same set. A plastic spudger from my first shell kit that still works perfectly. Angled ESD tweezers. A small magnetic mat. And a desk lamp I already owned.

Total investment in tools beyond what came with my first kit: about $12. And honestly, the tweezers and magnetic mat are convenience items, not necessities. The core job gets done with three tools and good light.

FAQ

Can I use a flathead screwdriver instead of a Y00 tri-wing?

Absolutely not. A flathead will strip tri-wing screws almost instantly. The Y-shaped recess requires a matching Y-shaped driver tip. There is no substitute that works reliably. Buy or borrow a Y00 driver — it’s the one tool where the exact specification matters.

What if my kit doesn’t include any tools?

Buy a Y00 tri-wing and #00 Phillips separately. A plastic spudger or guitar pick can serve as a pry tool. You can get all three for under $10 online. Don’t let the lack of included tools stop you — the individual tools are cheap and widely available.

Do I need different tools for the Switch OLED versus the original?

No. The Joy-Con hardware is identical across original Switch, V2, and OLED models. Same screws, same internal layout, same tools. The only tool differences come into play if you’re doing a console body swap, where OLED and original Switch have different screw layouts.

Is a powered screwdriver safe to use on Joy-Con screws?

I’d avoid it. The screws are tiny and the material is soft. A powered driver applies too much torque too quickly, and it’s very easy to strip a screw or over-tighten and crack a mounting post. Manual drivers give you the tactile feedback to know when a screw is seated properly. Go slow and feel the resistance.
