DIY Steam Deck Mod Tools for Beginners: What You Actually Need Before You Start
Modding the Steam Deck has become increasingly popular — from replacing backplates and shells to improving cooling and customizing the look of the device. If you’re new to DIY mods, though, the biggest question usually isn’t what mod to buy, but what Steam deck mod tools you actually need before opening your Steam Deck.
This guide is written specifically for beginners. No fluff, no overkill — just the essential tools and items you’ll realistically need to complete common Steam Deck mods safely and confidently.
Whether you’re planning a backplate replacement, shell swap, or internal upgrade, this post will help you avoid unnecessary purchases while making sure you don’t get stuck halfway through a mod.
Before You Start: A Quick Reality Check
DIY Steam Deck mods are not difficult, but they do require patience and the right tools. You’ll be opening the device, handling small screws, and working near sensitive components.
This guide is best for:
- Users comfortable following step-by-step instructions
- Anyone planning AliExpress mods (backplates, shells, cooling parts)
- Beginners who want to avoid damaging their Steam Deck
If you tend to rush repairs or skip instructions, modding may not be for you — and that’s okay. The goal here is to know what you’re getting into before you buy anything.
Steam Deck OLED vs LCD: Compatibility Matters Before You Buy
Before purchasing any mod parts or accessories, it’s important to understand that the Steam Deck OLED and the original LCD model are not internally identical.
While many tools work for both versions, some accessories and mod parts are model-specific.
What’s usually the same
Most tools are universal across both models, including:
- Precision screwdriver sets
- Plastic pry tools
- Tweezers
- Magnetic screw mats
- General repair and organization tools
If you’re only buying tools, you’re generally safe regardless of which Steam Deck you own.
What can be different
Accessories and mod parts that may not fit both models include:
- Backplates
- Shells
- Internal brackets
- Cooling mods
- Certain thermal components
The OLED model has:
- A revised internal layout
- Different component placement
- Updated thermal and structural elements
Because of this, a backplate or internal mod designed for the LCD Steam Deck may not fit the OLED model, even if it looks similar in photos.
Beginner rule of thumb
- Tools → Usually universal
- Mod parts → Often model-specific
Always check whether a product listing clearly states OLED, LCD, or OLED-compatible before ordering — especially on AliExpress.
The Core Tools You’ll Need (Non-Negotiable)
These tools cover roughly 90% of common Steam Deck mods, including backplate replacements.
Precision Screwdriver Set
This is the most important tool you’ll buy.
Steam Deck screws are small and easy to strip if you use the wrong bit. A quality precision screwdriver set with multiple bit sizes is essential.
What to look for:
- Magnetic tips
- Phillips and Torx bits
- Comfortable grip for slow, controlled turns
Where to buy:
- AliExpress: Budget-friendly sets that work well for occasional mods
- Amazon: Higher-quality kits with better durability and faster shipping
If you plan to do more than one mod, spending a little extra here is worth it.
Plastic Pry Tools / Opening Picks
Never use metal tools to open your Steam Deck.
Plastic pry tools help separate the backplate without scratching the shell or damaging internal clips.
Why they matter:
- Reduce cosmetic damage
- Prevent slipping into internal components
- Make shell separation much easier
Many AliExpress mod kits include basic pry tools, but standalone sets are inexpensive and useful beyond one project.
Tweezers (Fine Tip)
Tweezers aren’t strictly required, but they make modding much easier.
They’re useful for:
- Handling tiny screws
- Positioning cables
- Removing debris or thermal material
A simple fine-tip pair is all you need.
Thermal & Cooling Supplies (Often Overlooked)
Some Steam Deck mods involve exposing internal components or altering airflow.
Thermal Paste
If your mod involves removing internal parts or upgrading cooling, fresh thermal paste may be required.
If you’re only replacing a backplate, this may not be necessary — but having it on hand prevents surprises mid-project.
Amazon is usually the safer option here due to consistent quality and easier returns.
Thermal Pads (Optional)
Certain backplates or cooling mods recommend thermal pads to improve heat transfer.
Only buy these if:
- The mod specifically calls for them
- The listing clearly states OLED or LCD compatibility
- The required thickness is specified
Guessing here can cause more problems than it solves.
Organization & Safety Tools (Highly Recommended)
These tools don’t modify your Steam Deck directly, but they prevent mistakes.
Magnetic Screw Mat or Organizer
Steam Deck screws vary in length. Mixing them up is one of the most common beginner mistakes.
A magnetic mat helps you:
- Keep screws organized
- Remember where each screw came from
- Work calmly without rushing
This is one of the best-value beginner purchases you can make.
Basic Anti-Static Protection
You don’t need a full anti-static workstation, but basic precautions help.
Simple options include:
- Anti-static wrist strap
- Anti-static mat
- Working on a non-carpeted surface
These reduce the risk of accidental static discharge during internal mods.
Optional but Helpful Extras
Not required, but commonly used by modders:
- Isopropyl alcohol (90%+) for cleaning surfaces
- Replacement screws in case one goes missing
- Gloves or finger cots to avoid fingerprints
These are inexpensive and often worth having nearby.
Can You Buy Everything in One Kit?
Sometimes — but rarely perfectly.
Most all-in-one kits:
- Include usable pry tools
- Include acceptable screwdrivers
- Cut corners on quality
Best beginner approach:
- Buy a solid screwdriver kit
- Add pry tools and organization separately
- Supplement with AliExpress kits bundled with your mod
This avoids overbuying while keeping you prepared.
AliExpress vs Amazon: What Makes Sense Where?
Both platforms serve different purposes when it comes to Steam Deck mod tools.
AliExpress is best for:
- Mod-specific tool kits
- Budget pry tools
- Accessories bundled with backplates or shells
Amazon is best for:
- Precision screwdriver sets
- Thermal paste
- Organization tools
- Faster shipping and easier returns
Using both together usually gives the best overall experience.
Who Should NOT Attempt DIY Mods?
DIY mods are rewarding — but not for everyone.
You may want to avoid modding if:
- You’re uncomfortable following instructions
- You need your Steam Deck working immediately
- You dislike working with small parts
There’s no shame in keeping your device stock. Modding should feel optional, not stressful.
Final Thoughts: Start Simple, Build Confidence
If you’re new to Steam Deck modding, start with a basic backplate or cosmetic mod. These require fewer tools and help build confidence before attempting more complex upgrades.
You don’t need a workshop — just:
- The right tools
- A clean workspace
- Patience
Once you’ve completed one successful mod, the rest become much easier. DIY modding isn’t about rushing — it’s about doing it right. Start prepared, and your Steam Deck will thank you.
