The short answer: To install keycaps, align the keycap over the switch stem and press down gently until it clicks into place. For larger keys like spacebar, use the included stabilizers. That’s it, but there are nuances to avoid damaging your keyboard.
Before you start, know your switch type. Mechanical keyboard switches come in two main stems: Cherry MX (cross-shaped) and Topre (slider). Most keycaps are designed for Cherry MX compatible switches, which include clones like Gateron and Kailh. If you have a Topre keyboard, you need special keycaps. Also, check the keycap profile (OEM, Cherry, SA, etc.) as it affects the height and shape, but any profile fits on the switch as long as the stem matches.
You don’t need much, but a wire keycap puller is highly recommended over a plastic ring puller. The wire puller grips underneath the keycap without scratching it. A brush or compressed air for cleaning is optional. If you’re replacing keycaps, you might want a small tray to organize them. No other special tools are required, but a stable work surface and good lighting help.
1. Remove the old keycaps: Use a wire puller. Position the wires under the keycap, press down, and gently pull straight up. Do not twist or pry, as that can damage the switch.
2. Check alignment: Look at the bottom of the keycap. There is a cross-shaped socket that must match the switch stem. For keys with stabilizers (spacebar, shift, enter), align the keycap with the stabilizer bars or clips.
3. Press down: Place the keycap over the stem and press straight down. You should feel a click or a slight resistance. Ensure it’s fully seated. For stabilized keys, press on both sides evenly to avoid bending the stabilizer.
4. Test each key: After installing, press each key to ensure it functions smoothly. If a key feels sticky or doesn’t spring back, remove and reseat it.
Do not force a keycap onto a switch that doesn’t match; it can break the stem. Avoid using excessive force when pressing down, as that can damage the switch or the keycap. Also, be careful with the stabilizers: if a stabilizer clip comes off, you’ll need to reattach it. Another mistake is mixing up keycap profiles, which can cause uneven typing. So, keep your keycaps organized by row.
Keycaps are typically made of ABS or PBT plastic. ABS is softer and may shine over time, while PBT is more durable and texture-rich. When installing, the material doesn’t change the process, but be aware that thin ABS keycaps can crack if you press too hard. Double-shot keycaps (like those from high-quality brands) are more robust. If you bought a custom keycap set, check if it includes a keycap puller and extra stabilizers.
Once your keycaps are installed, clean them periodically. Remove them using the puller and wash with warm soapy water, then dry thoroughly before reinstalling. If you’re upgrading to a new set, consider the layout compatibility for your keyboard. Some sets lack keys for non-standard layouts like 65% or 75%.

Yes, you can use your fingers or a flat tool, but it’s risky. Fingers can slip and damage the switch. A wire puller is cheap and safe.
Check your switch type. If it’s Cherry MX style (cross shape), most keycaps will fit. If you have a Topre or ALPS, you need specific keycaps.
Check for debris or damage. Clean the switch stem with compressed air. Ensure the keycap socket is aligned correctly. If it still doesn’t fit, the keycap may be defective or incompatible.
