Keycaps 101: What Actually Matters
Keycaps are just plastic pieces that sit on top of your mechanical keyboard switches. They look simple, but there's a lot that goes into picking and installing them without wasting money or time. Most people buy the wrong profile or material and end up annoyed after a week. Start with profile. That's the height and curve of the keycap shape. The common ones are Cherry (standard, low), SA (tall, vintage dome), XDA (flat, uniform height), and OEM (what most keyboards ship with). Don't get seduced by SA or DSA because they look pretty in photos. They feel weird once you actually type for hours. OEM is fine for beginners because it matches what most people already know. Then there's material. PBT ABS. PBT is textured, durable, resistant to shine. ABS is smoother, cheaper, develops a glossy finish from your fingers within months. I bought an ABS set on a whim back in 2019 and had to replace them within a year. Learned the hard way that PBT costs about thirty percent more upfront but lasts three times as long. Just get PBT.
Compatibility matters too. MX-style stem is universal for most mechanical keyboards. Some switches use different stems though, like Topre or alps. Make sure your switches match the keycap stem before ordering.
Installing them without breaking anything
Get a keycap puller. Wire pullers work fine and cost about five dollars. Foam strap pullers are easier on fragile keycaps but they're more expensive. I prefer wire. Pop each key straight up with even pressure. Don't wiggle it side to side because that damages the stem over time. When putting new caps on, press down firmly and straight. Angled force can crack the plastic or bend the stem. It sounds obvious but I've seen people rush and break caps this way all the time.

Keycaps Tutorial Easy: getting started without the confusion
If you want a Keycaps Tutorial Easy to follow, here's the basic workflow. Identify your keyboard's switch type. Measure the stem size. Pick a profile that suits your typing style, not what looks cool online. Order PBT keycaps in the right size layout for your board. Use a wire puller to remove old caps one at a time. Clean the switches with compressed air. Snap new caps on straight. Done. The whole process usually takes about twenty minutes for a standard tenkeyless keyboard. Full-size boards take longer because there are more keys, but nothing complicated about it.
Pitfalls I ran into
One thing nobody warns beginners about: laser etching fades over time on cheap PBT. If the legends disappear after six months of heavy use, that's on you for buying budget keycaps. Spend a little more on dye-sublimated legends. They last years. I found this out after buying a forty dollar set that looked great day one and was half illegible by month eight. Another issue: stabilizers. When you replace keycaps on larger keys like spacebar, shift, or enter, the stabilizer wires can interfere. You sometimes need to lift the cap at an angle rather than pushing straight down. It's a minor thing but it stalls people who don't know it exists. If your keyboard has a non-standard layout like 60 percent or split ergonomic, make sure the keycap set you buy covers that layout. A lot of sellers list "104 key" sets that won't fit your board properly even if the stems are the same. Check the product details carefully.
PBT Shine is real. Even high quality PBT will develop a slight sheen from hand oils over a year or two. It doesn't ruin the caps but if you want them to stay matte forever, nothing does. Some people accept it, some don't. Just know it happens.
