Steam Deck Right Trigger Replacement

Introduction

Go to step 1 ↓

Use this guide to replace the right trigger assembly (R2) on your Steam Deck LCD. Although nearly identical, the procedure for the left trigger (L2) can be found here.

Remember: follow general electrostatic discharge (ESD) safety procedures while repairing your device.

Replacement triggers require calibration to work as expected. Read about how to do that here.

      • Turn on your Steam Deck and allow the battery to discharge below 25% before starting your repairs, as a charged lithium-ion polymer battery can be dangerous if accidentally punctured.

      • As an extra precaution, Valve recommends putting your Steam Deck into battery storage mode within the BIOS before starting any internal repairs. Read how to do that here.

      • Power down your Steam Deck and unplug any cables.

      • If you have a microSD card installed, make sure to remove it before opening the Steam Deck. If you attempt to remove the back cover with it still installed, it could snap right in half.

      • During your repair, it can be helpful at times to lay the Steam Deck face-down into its case to protect the thumbsticks and prevent wobble.

      • Use a Phillips driver to remove the eight screws securing the back cover:

      • Four coarse thread 9.5 mm-long screws

      • Four fine thread 5.8 mm-long screws

      • Despite the standards, Phillips screwdrivers can vary in size and shape—two drivers labeled as the same size may fit differently in the same screw. Use the size that fits the snuggest into the screw head.

      • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your Steam Deck.

      • Insert an opening pick into the thin gap between the back cover and the front shell, along the edge of the right grip.

      • If you're having trouble inserting your pick at the grip seam, try starting at either the top or bottom long edges first, then slide the pick towards the grip.

      • Pry up on the back cover to release it from the locking clips.

      • Once the clips are disconnected from one edge, the rest disconnect easily.

      • Grip the back cover at the opening you just created and pull it up and away from the device to unclip the long edges.

      • Remove the back cover.

      • If you have a refreshed Steam Deck version with the black motherboard cover, skip this step.

      • Use a pair of tweezers to remove the piece of foil tape covering the hidden screw on the board shield.

      • If possible, try not to rip or tear this tape so it can be reused. If necessary, you can fashion a replacement by cutting a piece of aluminum foil tape to fit.

      • Remove the board shield.

      • Depending on the age of your Steam Deck, this shield may stick to the thermal pads underneath.

      • During reassembly, ensure that the fan cable lays on the side of the board shield and isn't pinched underneath.

      • Grip the battery cable by its pull tab and pull it directly away from the motherboard to disconnect it.

      • Alternatively, use the flat end of a spudger or a clean fingernail to gently push the connector out of its socket, then disconnect it completely by hand.

    1. Steam Deck Right Trigger Replacement, Unclip the right trigger: step 9, image 1 of 2 Steam Deck Right Trigger Replacement, Unclip the right trigger: step 9, image 2 of 2

      • The right trigger will be on your left-hand side when working on the Steam Deck, as it's laying upside down.

      • The Steam Deck's triggers clip into place on two pegs on the trigger bracket, which doubles as the hinge.

      • Place the flat end of a spudger onto the inside edge of the trigger's right clip.

      • Pivot the trigger clip out, away, and up from the peg to unlatch it.

      • During reassembly, latch the outermost peg first. Once in place, push down on the trigger to latch the innermost peg, producing an audible "click" sound.

      • Check to make sure that the trigger spring is properly aligned. Test the trigger action before continuing reassembly.

      • Remove the right trigger.

      • Take care to not lose the trigger spring. It press-fits onto a peg on the trigger's underside.

This would be useful if you could actually find replacement triggers at all. I live in the UK, and cannot source these at all. I even contacted Valve about it and they cannot help me :(

I bought my replacement from this website.

The shield doesn't need to be removed for this repair. The trigger is difficult to replace. Start with the outer peg first, leftside, and then position the right-side above the peg. Apply pressure to get it over the leg, then continue pressure to get it on the peg. A little tricky, and don't forget to attach the spring first.

My transistor on the left daughterboard is missing. I would like to buy a new transistor and solder it myself. Could you please provide me with the specifications of the transistor or give me a link to purchase one? The L2 button is not working because of it. It has the code "303" on it, you can see it in the images above

PSA: Bo Seller is right that you do not have to remove the shield. The only purpose of steps 5–8 is to enable you to disconnect the battery, which is not essential. I skipped steps 5–8 and did not have any trouble with the repair.
