Keycap Installation & Removal Help

Keycap Installation & Removal Guide

Four steps, no force, and stop the moment something does not line up.

This guide covers standard keycaps, large stabilised keys and sculpted artisan caps on a mechanical keyboard. Where your own board has specific instructions — for hot-swap switches or stabilisers, for example — the keyboard maker's guide takes priority over this page.

Fitting a keycap is a dry, powered-off job. Never press a cap on that does not sit flat, and never test a key with the case open.

01 — What ships with your order

Tools and key counts are listed per set, not assumed

What comes in the box depends on the SKU, the variant and the benefits attached to your order. Tools are listed per set rather than described as included with every order. Our three-piece keyboard care kit — QuadPull, precision brush and 2-in-1 switch and keycap puller — is its own product, and a QuadPull gifted with a first keycap set order on Club is a separate benefit, not the same thing as that upgrade.

Each set states its own key count. The count is shown as the total number of keys, a laid-out photo of the keys you actually get, and a note on the special widths and extra keys in the set. ISO Enter, the short Shift, the different spacebar lengths and the bottom-row extras are marked on that image, and only keys that are really in the set are counted.

Reading the included-keys list
What the listing shows What it tells you
Total key count How many caps the set containsthe number matches the laid-out photo, not a competitor's count
Laid-out photo of the keys Every cap you receive, shown flat, so you can check a layout before buying
Special widths and extras marked ISO Enter, short left Shift, the spacebar lengths and bottom-row extras your board may need
Which keys are not included Anything outside the photographed set — check before you rely on it

Browse the keycap sets and open the included-keys list on the set you are considering — the View included keys list on a set such as Rhapsody MOA is a worked example. If a key your layout needs is not in the photo, ask us before ordering.

02 — Removing a standard keycap

Steps 1 and 2: prepare, then lift straight up

Step 1 — power off and check the fit

Disconnect the keyboard, then photograph the layout so you know where every cap goes back. Check the cap's mount, its width and its row height against the position you are about to fit it to. If they do not match, stop — do not fit it.

Step 2 — remove with an even, vertical pull

Use a puller that fits the cap. Hook both side lower edges evenly, keep the cap centred and lift slowly and straight up. Do not pull at an angle, twist or yank.

The QuadPull is for four adjacent standard caps: keep the tool level and lift vertically. It is not for the spacebar, Enter, Shift or Backspace, or for any key with stabilisers — see section 04.

Low-profile boards and tightly spaced layouts can leave no room for a multi-key puller. Check the clearance before you use one, and switch to a single-key puller if the tool does not sit flat.

QuadPull held level over four adjacent keycaps and pressed down evenly, then the four removed caps laid out in order beside the tool.
QuadPull: sit the tool level over four adjacent standard caps, press evenly, then set the removed caps aside in the order you took them off.

03 — Fitting a keycap back on

Steps 3 and 4: press vertically, then test

Step 3 — align the socket and press down

Line the cap's cross socket up with the switch stem and press it down vertically and gently. No tapping, no force. On a large key, line up the centre stem and both stabiliser connectors at the same time, and follow the keyboard maker's instructions for that key. Do not remove four large keys at once.

Step 4 — check the feel, then power on

Before switching the board on, confirm that the key rebounds properly, sits in the right position, clears its neighbours and faces the right way. Then connect and test the key.

Tools by key type
Key type How to handle it
Adjacent standard keycaps QuadPull is fine — hold it level and pull vertically
Spacebar, Enter, Shift, Backspace, anything with stabilisers Not with QuadPull. Align the stem and both stabiliser connectors and follow the keyboard maker's guide
Sculpted artisan caps By hand, at the sturdy base close to the cross socket — never by the decorative ears, corners or petals

If a switch comes up together with the cap, stop immediately. Check whether your board is hot-swap and look at the state of the pins, then reset the switch following the keyboard maker's guide. Never press a switch back in while the keyboard is powered.

04 — Large keys, stabilisers and artisan caps

Where a multi-key puller stops being the right tool

Large keys sit on stabilisers, and those connectors have to line up at the same time as the centre stem. Work out how your board's stabilisers are fitted — plate-mounted, screw-in, or a board-specific design — and follow the keyboard maker's instructions for removing and refitting that key. Remove large keys one at a time.

Sculpted artisan caps are handled differently. Hold the solid base near the cross socket and never grip the ears, corners, petals or other protruding detail, and never use a multi-key puller on a sculpted piece. On our own artisan caps, the safe contact points are marked on the product photos of that specific design — check the listing for the piece you have.

See the artisan keycap collection for the design you own, and the compatibility guide if you are not sure your board takes the cap at all.

05 — Resin caps that fit too tightly

The heat method, and only for the models it was written for

This applies only to the resin models that shipped with these softening instructions — it is not a general method for every artisan cap. First confirm that the stem specification matches; if the cap was never meant for that switch, stop here.

  1. Warm the cap. Use a hairdryer on its warm setting, or place the cap in water at 50–70 °C for about 15 seconds, so the material softens. Keep the dryer away from the cap, never use an open flame, and watch for burns and material damage.
  2. Dry it straight away. After the water, wipe the surface and the cross socket immediately, and make sure no water can get into the switch.
  3. Seat it while it is still soft. Align the cross socket with the stem and press it on gently — do not wait for the cap to cool first, or you lose the softening you just created.
  4. Let it cool, then check. Leave the cap alone until it has reached room temperature, then confirm it is seated firmly.

Two ways to soften it

Four panels: warming an artisan keycap with a hairdryer on its warm setting, lowering it onto the switch stem, pressing down on both sides, then the seated cap checked on the keyboard.
Warm air. Heat the cap on its own, seat it on the cross stem while it is still soft, then leave it to cool to room temperature before checking it.
Four panels: an artisan keycap in water at 50 to 70 degrees Celsius for about 15 seconds, the cap and cross socket dried, the cap pressed onto the stem, then left to cool with a clock icon.
Warm water. 50–70 °C for about 15 seconds, dry the surface and the cross socket, press onto the cross stem, then let it cool to room temperature.

Stop and contact support at support@simpocubic.com if you cannot dry the cap in time, or if it still will not go on. This is an installation fix for specific resin models — it is not cleaning advice, and caps should not be soaked as part of a routine.

Do not improvise beyond the instructions supplied with the cap: if your model did not come with this guidance, contact us rather than heating it.

06 — Checking the order when it arrives

Look before you fit

Check the outer packaging, the number of keys, the key positions, the surface of each cap and the cross sockets soon after delivery. It is much easier for us to put something right before the caps have been used.

If a key is missing, the wrong item arrived, or something is damaged, send us the order number and clear photos, and keep the outer carton and packaging so it can be checked. An unboxing video helps explain what happened, but it is not the only evidence we accept — and there is no 24- or 48-hour cut-off after which a claim is automatically refused.

A missing key is replaced with a single key once verified. Damage and defects are handled under the Returns & Refunds policy.

07 — ISO and ANSI layouts

A physical difference that force cannot fix

ANSI and ISO differ in the shape of the keys — a wide ANSI Enter against a tall ISO Enter, and the keys around the left Shift. If a cap does not sit right, stop: remove it the correct way, then check the Enter, the left Shift, the bottom row and the spacebar length against the board.

Supported SIMPOCUBIC kits include the ANSI and ISO keys together — 130+ keys covering full-size boards and many compact layouts. Use the matching extra key from the set rather than pressing the wrong one into place. The ISO & ANSI keycap guide explains which keys differ.

If the key your layout needs is not in the set, contact us with the keyboard model, photos of the layout and the positions you are missing. We confirm whether a single key is available, whether an exchange is possible and what it costs before anything is arranged — we do not promise free extra keys for every layout.

08 — Questions about fitting keycaps

Five things buyers ask most

Can I use the QuadPull on every key?

No. It is designed for four adjacent standard keycaps on a mechanical keyboard. Keep the tool level and pull vertically. It is not intended for oversized or stabilised keys such as the spacebar, Enter, Shift or Backspace, and it should not be used on sculpted artisan caps — those are handled by hand at the sturdy base. On low-profile or tightly spaced boards, check the clearance before using it.

My resin keycap will not go on. Can I heat it?

Only if your cap is one of the resin models that shipped with the softening instructions, and only after confirming the stem specification matches. Warm it with a hairdryer on the warm setting, or in water at 50–70 °C for about 15 seconds, then dry the surface and the cross socket immediately so no water reaches the switch, and seat it while it is still soft. Let it cool to room temperature before checking the fit. Never use an open flame. If it still will not go on, or you cannot dry it in time, stop and contact us.

A switch came up together with the keycap. What should I do?

Stop immediately and do not press anything back in while the keyboard is powered. Check whether your board is hot-swap and inspect the state of the pins, then reset the switch following the keyboard maker's guide. If the switch or its sockets look damaged, contact us before using the board again.

My ISO board needs a key that is not in the set. Can you send one?

Do not force the cap that is closest in size. Contact us with your keyboard model, photos of the layout and the positions you are missing. Supported kits already include the ANSI and ISO keys together, so check the included-keys list and the ISO & ANSI guide first. We will confirm whether a single key is available, whether an exchange is possible and what the cost is before arranging anything.

What should I check when the parcel arrives?

The outer packaging, the number of keys against the included-keys list, the key positions, each cap's surface and the cross sockets. Report anything missing, wrong or damaged with your order number and photos, and keep the carton and packaging for inspection. An unboxing video helps but is not the only evidence we accept, and there is no 24- or 48-hour deadline that cancels a claim.

Not sure a cap is meant for your board?

Send us your keyboard model and a photo of the position you are fitting, and we will tell you whether the set covers it — before you force anything into place.
