MacBook Keyboard Replacement: Why Apple Quotes For The Whole Top Case

On most modern MacBooks the keyboard is riveted into the top case, so Apple replaces the whole assembly. Replacing only the keyboard costs much less.

Why a keyboard repair is quoted as a top case

On most MacBooks from the last decade the keyboard is not screwed in but riveted into the top case — the aluminium shell around the keyboard. That is why an official keyboard repair is usually quoted as a top case replacement, which commonly comes to £450–£600. Replacing only the keyboard — removing the old one, fitting a new one and securing it in place — typically comes to £150–£350, and the rest of your top case stays as it is.

Not every keyboard fault needs a whole new keyboard. A single key that has stopped working or feels gritty can often be cleaned or have its key cap and clip replaced on its own. The longer a sticking key is forced, though, the more likely the small clip underneath breaks, and liquid under the keys keeps corroding until it is cleaned. Getting a faulty key looked at early is often the difference between a small fix and a full keyboard.

Need help right now? Our MacBook Keyboard Replacement engineers can come directly to your home or office anywhere in Greater London to diagnose and fix this for you.

Test the problem keys in a plain text document to see whether they fail to register, repeat, or both.
Hold the Mac at an angle and use short bursts of compressed air under the affected keys, as Apple itself recommends.
Plug in a USB or Bluetooth keyboard. If that works normally, the Mac is fine and the fault is in the keyboard alone.
If liquid was spilled, switch the Mac off and keep it switched off. A keyboard fault after a spill needs cleaning, not testing.

How we fix the keyboard without replacing the top case

The aim is to fix the fault you actually have at the lowest sensible cost, which means finding out exactly which keys fail and why before anything is replaced.

Work out whether it is one key, a group of keys or the whole keyboard, because each has a different and differently priced fix.
Check for liquid residue under the keys and on the board beneath, since a spill can affect more than the keyboard.
Fit a new keyboard and secure it properly, then test every key and the backlight.
Check the trackpad, battery and internal cables while the Mac is open, so nothing else is missed.

Keeping the keyboard working for longer

MacBook keyboards are sensitive to dirt and liquid, but a few habits keep most problems away.

Keep food and drink away from the keyboard, as crumbs and spills cause most of the key faults we see.
Clean around the keys with compressed air now and then, before debris works its way underneath.
Skip thick silicone keyboard covers. They trap heat and can press against the screen when the lid is closed.
