Piano keytop replacement means removing the worn, chipped or missing covers on the white keys and bonding new ones to the wooden keysticks. Then comes the part people overlook: trimming the new material flush, and leveling and regulating the keys so the keyboard still plays evenly. A set of keytops is cheap. The skill is in the fitting, and that is where most of the cost, and most of the risk, sits.
This guide walks through the real steps, compares materials, explains why the job is rarely “just new covers,” and helps you decide whether to hire a technician, try it on a spare keyboard, or learn the trade properly.
TL;DR
- Keytop replacement is a precision job: remove old tops and glue, prepare the keystick, bond new material, file it flush, then level and regulate the keys.
- Modern acrylic and mineral-based plastics are the usual choice. Ivory looks and feels wonderful but chips more easily, and buying or selling it is heavily restricted.
- The Piano Technicians Guild warns that jobs that look DIY-friendly can be a trap. Mistakes in the wood or the fit are hard to undo.
- Ask any technician for an itemized quote that covers keytops, keystick preparation, and key leveling or regulation, not only the covers.
- If you want to do this work for yourself or others, structured training beats trial and error on a good piano.

What keytop replacement actually involves
The keytop is the thin layer on the surface of each white key, the part your fingers touch. On older pianos it was often ivory. On most pianos built in the last several decades it is plastic. Over years of playing, tops wear thin, crack, yellow unevenly, lift at the edges or go missing entirely.
Replacement is not a sticker job. A technician typically works through these stages:
- Remove the keys. The keys come off the keyframe so they can be worked on at a bench. This also lets the technician check bushings, key pins and general condition.
- Strip the old tops and adhesive. Old glue has to come off completely. Leftover residue leads to hollow spots or lifting later.
- Prepare the keystick. The wood under the top must be clean, flat and, in most cases, planed or sanded to make room for the thickness of the new material.
- Bond the new tops. A suitable adhesive is applied and each top is positioned precisely, then clamped or pressed.
- Trim and file flush. The overhang is removed and the edges brought flush with the wood, without nicking either surface.
- Level and regulate. Key height, depth and the feel of the action are checked and corrected.
The last step is the one that separates a good result from a keyboard that looks new but plays badly.
Why it is never “just new covers”
A common misconception among owners is that the keys simply need new covers. Experienced technicians in the Piano Technicians Guild community tend to stress that the fit and the regulation decide how the keyboard feels, not the material alone.
The reason is physical. A new top changes the thickness and mass at the front of every white key. If the wood was not planed to compensate, the keys sit higher, and the keyboard can feel choppy or the keys can feel buried at the bottom of the stroke. Uneven preparation shows up as a saw-tooth look across the keyboard. A technician in a Pianotech discussion on trimming keytops describes the standard approach when replacing ivories: plane the keysticks so the overall key thickness does not change. If that was not done, the workarounds include thinner fallboard felt or ribbon under the fallboard, a sign of how far a thickness error ripples through the instrument.
The Guild’s own guidance on basic piano care cautions that tasks that look like easy DIY projects are often a trap for the uninitiated, that amateur repairs can cost more to correct than the original problem, and that the value of a good instrument can suffer. Keytops are a textbook case.
Key leveling comes with the job
Once the new tops are on, every key needs to sit at the right height relative to its neighbors. Some makers specify more than a flat line. The Steinway technical reference guide hosted by a PTG chapter, for example, notes that Steinway pianos use a slightly crowned key level, with the center of the keyboard about 1/32 inch higher than the ends. A technician who levels to the wrong target after a keytop job can leave a good piano feeling wrong.
Keytop materials compared
Keytops fall into two broad families: natural (ivory, bone) and synthetic (acrylic, celluloid, and mineral-filled plastics). What fits depends on the piano, your budget and how the instrument is used.
| Material | Look and feel | Durability | Best for |
|---|---|---|---|
| Genuine ivory | Fine grain, slightly porous feel, warm look | Can chip and split, especially with heavy or youthful use | Historically significant instruments, restorations that must stay original |
| Standard molded acrylic | Clean and bright, smoother surface | Tough and consistent | Most family pianos, schools, studios |
| One-piece acrylic with fronts | Same as above, with the front already formed | Tough, fewer seams | Full keyboard refreshes |
| Mineral-based plastics (sold under names like Ivoplast or Tharan) | Closer to ivory’s texture and grip | Durable, with an ivory-like feel | Owners who want the feel of ivory without its fragility |
Prices vary widely by region, shop and the condition of your keys, so ask for a written, itemized quote rather than relying on a per-key figure you saw online. Retail listings for loose acrylic keytops, for instance, range from a few dollars to a few dozen, but those are parts only and say nothing about the labor to fit them.
What about ivory?
If your piano still has ivory, you generally do not need to remove it just because it looks tired. Technicians restore ivory by repairing loose pieces, filling chips and polishing. Replace it when the damage is widespread, when pieces keep lifting or when the keys are sharp-edged and uncomfortable to play.
Before you plan anything, remember that selling and moving ivory is tightly regulated in the United States, and rules vary by state. If you are replacing ivory on a piano you plan to sell or ship, check current federal and state rules or ask a technician who handles ivory regularly. Never assume removed ivory can be sold on.
Doing it yourself: what the work really demands
Some owners will try this. A few things are worth knowing before you do.
Removing old ivory is where wood gets damaged
Ivory tops are commonly released with heat, then lifted with a blade. Guild community material on the subject warns that the blade can dive into the wood grain and ruin a keystick, and that working from both directions helps if the grain begins to tear. The same material notes that old glue must be completely removed so the new top bonds well. In practice, one slip with a blade can cost you a key.
Filing is a skill, not a finishing touch
Beginners underestimate the trimming stage. Professionals typically use a metal file with one edge ground smooth so it does not mark the wood, and they take the new material down until it is exactly flush. A nick in the wood or in the top cannot be fixed afterward. Glue squeeze-out should be wiped away right away with a damp cloth, because dried adhesive turns hard and is difficult to remove without harming the finish.
Tools and consumables
You need a way to hold keys safely, a suitable adhesive, clamps or a press, files, a flat surface for checking, and key-leveling and regulation tools. If you are building a kit for ongoing work, our technician tools collection is a place to start.
A realistic approach
- Practice first on a junk keyboard or spare keys, never on the only piano in the house.
- Do not replace tops on a piano with valuable or historic keys.
- Plan for regulation afterward, not as an optional extra.
- If the instrument is a good one, have a technician do the work, or at least inspect it.
How to choose a technician
When you collect quotes, compare the scope, not only the total:
- What is included? Removal, keystick preparation, new tops, trimming, and leveling or regulation should all be named.
- Where is the work done? Keytop replacement is normally done in a shop, so ask about transport and timeline.
- What else will be checked? Key bushings, key pins and the front rail are easy to inspect while the keys are out. Replacing worn bushings at the same time avoids taking the keyboard apart twice.
- What material is proposed, and why? A good technician should explain the trade-offs for your piano, not push one choice for every job.
- Is the technician credentialed? The Piano Technicians Guild offers the Registered Piano Technician designation, a common way to find someone who has demonstrated their skills.
If the quote looks suspiciously low, it probably leaves out the preparation and regulation that make the keyboard play well.
Our perspective on keytops
When students ask us about keytops, we usually start by moving the conversation away from the covers. Everyone sees the cracked ivory or the missing top. Few people see the keystick, the key height, the bushings and the regulation that decide whether the finished keyboard feels right.
We teach piano technology as a connected system. A keytop job touches key leveling, key depth, friction and the overall touch of the action, so we encourage students to learn it alongside regulation, not as a stand-alone trick. Our curriculum is built around preparing students for the Piano Technicians Guild’s RPT exam, and keyboard work is part of the competence a technician needs to show.
Our honest advice to owners: if the piano matters to you, pay for the preparation and the regulation, and ask your technician to explain both. Our advice to would-be technicians: practice on spare keys, learn to file and level before you charge anyone, and treat every mistake in the wood as permanent.

Turning this skill into a trade
Keytop work is one of the repair services that clients regularly ask a technician for, which makes it a useful skill if you want to build a piano service business or add repair income to a tuning practice. It is also a good example of why self-taught shortcuts fall short: success depends on touch, measurement and sequence.
Our Piano Tuning and Repair Online Course is a fully online, self-paced program for people who want to learn tuning and repair from basic techniques to advanced work, priced at $1,800 as a one-time purchase. There is also an Apprentice Version at $1,800. Once you have the foundations, the Field Regulation and Field Repair courses are available at $449 each, and they pair naturally with keyboard work. If you are not sure how to fund training, our guide on how to pay for piano tuning school covers the options, and our article on finding a piano tuning apprenticeship explains the hands-on route.
Planning your own keytop project
Whether you hire out or do it yourself, a short checklist keeps things on track:
- Assess the keys. Are tops worn, cracked, missing or lifting? Is the wood underneath sound?
- Decide on material. For most pianos, a quality synthetic top is the practical choice. Keep ivory for instruments where originality matters.
- Check the whole keyboard. Bushings, key pins and balance rail wear should be looked at while the keys are out.
- Confirm the scope in writing. Preparation, fitting, filing and leveling or regulation.
- Allow for time. A shop-based job means the keys leave the house, so the piano may be unplayable for a stretch.
- Test the result. Play every key softly and firmly. Look along the keyboard from the side for height variation, and check that the keys return cleanly.
FAQ
How do I know if my piano keytops need replacing?
Look for cracks, chips, missing pieces, tops that lift at the edges, or surfaces worn so thin that the wood or the glue shows. Rough or sharp edges that catch your fingers are another sign. Light yellowing alone is usually not a reason to replace.
Can I replace just one or two keytops?
Yes, a technician can replace or repair individual tops. Matching color and thickness to the surrounding keys is the difficult part, especially on older ivory or aged plastic, so expect a very close match rather than a perfect one.
Is keytop replacement a good DIY project?
It can be a learning project on a spare or low-value keyboard, but the Guild cautions that jobs like this can turn into a trap for beginners. Damage to the wood, poor trimming and unlevel keys are hard to reverse. For a piano you care about, hire a technician.
Do I need regulation after new keytops?
In most cases, yes. New tops change key thickness and can affect height and depth, so the keys should be leveled and the action checked afterward. Skipping this step is a common reason a freshly redone keyboard feels uneven.
Can I sell the old ivory removed from my piano?
Do not assume you can. Sales and interstate movement of ivory are tightly restricted in the United States, and state rules differ. Ask your technician and check current federal and state guidance before you do anything with removed ivory.
