How to change keycaps on a mechanical keyboard in easy steps

This tutorial covers everything needed to change keycaps on a mechanical keyboard safely: the right tools, how to remove each keycap without causing damage, how to clean the exposed board, and how to install replacement keycaps correctly, whether fitting standard alphanumerics or larger keys with stabilizers.

A complete guide to removing and fitting mechanical keyboard keycaps

Replacing keycaps is one of the easiest ways to begin keyboard customization. Before starting, check the keycap compatibility guide to confirm the switch stem, layout, and key sizing before ordering.

What tools do you need to remove keycaps safely?

A dedicated keycap puller is the most useful item: it grips the keycap underneath without putting unnecessary force on the switch stem or its top surface. Many premium double-shot PBT keycap sets, including premium double-shot PBT keycap sets, include one, so check the packaging before buying a separate puller.

When no keycap puller is available, a paperclip can serve as a short-term DIY alternative. Bend it into a tight U-shape, hook both ends beneath the keycap’s lower edge, and gently pull upwards with controlled pressure. Never use fingers, cutlery, knives, or flathead screwdrivers on a mechanical keyboard: they can scratch the caps and damage or snap switch housings. Wire-ring and plastic-ring pullers remain the better everyday option because they distribute force evenly; a paperclip only approximates that action.

Steps to remove every keycap without damaging switches

Before any keycap removal, unplug keyboard from the computer and photograph the complete layout. The image is particularly useful for modifier rows, where key sizes vary. Once the board is disconnected, work methodically from one corner instead of pulling at random.

• Alphanumeric keys Position the puller’s arms on the north and south edges of the keycap until it clicks into place, then gently pull upwards with steady, even pressure. Do not twist.
• Spacebar and larger keys Dislodge one side of the spacebar, then repeat on the opposite side. Larger keys use stabilizers, which must be disengaged gradually to avoid bending the stabiliser wire.
• Stubborn keycaps Rock the puller slightly from side to side on resistant caps. New PBT keycaps can have tight stems because of manufacturing shrinkage of approximately 1–2%, so patience helps prevent damage.
• Hard-to-reach keys Keys such as Esc near a tight frame may require the surrounding keycaps to be removed first, giving the puller enough clearance to sit correctly beneath the cap.

After removing every keycap, arrange them in the same order as on the board. Rows on a flat surface preserve the layout and make it easier to identify caps that need cleaning before you replace them. Set the stabiliser wires aside carefully so they are not bent during cleaning.

How to clean your keyboard after keycap removal

With the board stripped, turn it upside down and tap it gently over a bin to release loose debris. Then use compressed air in short bursts at an angle, keeping the can upright to prevent moisture from reaching the switch housings. A handheld vacuum is suitable for larger debris; avoid a full-power household vacuum, which can pull switch stems from their housings.

Wipe the exposed keyboard surface around each switch with a cloth lightly dampened with isopropyl alcohol. Cotton swabs can reach the narrow channels around switch housings. Soak removed keycaps in warm, soapy water, rinse them, and leave them to air-dry completely. Reinstalling a damp keycap could allow moisture to enter the switch type below it, so complete drying is essential.

How to install and seat new keycaps correctly

To align keycap with the correct switch, match the cross-shaped hole underneath the cap to the cross-shaped Cherry MX stem. This is the most widely supported mechanical switch geometry in aftermarket keycap sets. Press down slowly and firmly until a distinct snap is felt or heard. Resistance usually indicates misalignment, and excess pressure can crack the stem housing.

Spacebar, Enter, Shift, and Backspace each have three contact points: the central switch stem and two stabilizer posts. Press down in the centre first, followed by each outer edge. A rattling or ticking sound when these keys are pressed usually means that one stabilizer point has not engaged; remove the keycap, check the alignment, and reseat it rather than pressing harder. Once all keycaps are fitted, test every key to confirm full registration.

Frequently asked questions

Can you replace keycaps on any mechanical keyboard?

Most mechanical keyboards with Cherry MX-style switches accept aftermarket keycap sets without modification. The difference comes down to the switch stem geometry: a cross-shaped stem indicates MX compatibility, while Alps switches use a rectangular stem and Topre switches use a circular one. Both require dedicated caps and are not interchangeable with standard MX sets. Layout matters too. Spacebar width, modifier sizing, and the choice between an ISO and ANSI Enter key determine whether a set covers every position correctly.

How do you remove keycaps from a mechanical keyboard without causing damage?

A wire-ring or plastic-ring keycap puller is the safest tool for removing keycaps. Position its arms beneath the north and south edges until you feel a click, then pull upwards with even, controlled pressure. For larger keys with stabilizers, including the spacebar and Shift, pull upwards with even pressure on both sides so the stabiliser wire is not overstressed.

If a switch puller is not available, a U-shaped paperclip can work as an alternative. Avoid sharp objects such as screwdrivers and knives: they can scratch or crack the keycap and damage the switch housing underneath.

How do you install new keycaps correctly after removing the old ones?

A guide to installing keycaps correctly starts with checking that the keycap stem hole matches the switch type beneath it. With MX-compatible sets, both stems are cross-shaped and should align without force. Press down firmly. For stabilised keys, check that all three mounting points engage: the central switch stem and both stabilizer posts.

Rattle after installation usually indicates an unseated stabilizer point rather than a faulty keycap. Remove the cap and reseat it with even pressure across the centre and both sides, then test every key to confirm normal operation across the board.
