I have a 2021 16" Mac Book Pro, Pro M1 chip 16 GB running Sequoia 15.3.2. At times when typing the laptop will add an occasional random letter, n, m q, etc. no rhyme or reason. I admit I mayn not be the best typist however the random letters are no where near the letters I am typing. The above sentence shows a random n in the word may. I appreciate any guidance. Thx

There are NO discrete key-switches in these keyboards. The keyboard internally is built with two clear overlays, a rows layer and a (slightly diagonal) columns layer. When you press a key, it changes the electro-mechanical characteristics at the junction, which can be detected by the micro-controller in the keyboard as a distinct key-press.
When the keyboard starts to fail, typically we see failures nearby (same row or same column).
There is nothing inside the keyboard that can be repaired.
<< occasional random letter, n, m q, >>
Are those the Exact random letters added?
Hello Grant, it was usually n or m but now it has become random. The extra letters are no where near the letters typed and the word is initially spelled correctly but with an extra letter.
How can I fix typo issues on my MacBook Pro?
