Removing keycaps from a Model M keyboard involves understanding its unique two-piece keycap design. Based on available information, the process differs slightly depending on which part of the keycap you are removing.
Understanding Model M Keycap Design
Unlike many modern keyboards, the keycaps on an IBM Model M are composed of two distinct parts fitted together. This design impacts how they are attached and subsequently removed.
- Top Piece: This is the visible part with the legend (letter, number, or symbol) printed on it.
- Bottom Piece: This part connects the top piece to the key switch's spring mechanism underneath.
According to documentation from 18-Dec-2020, "The top piece comes off fairly easily with just your fingers, while the bottom piece is more firmly attached to the spring of each switch."
Removing the Top Keycap Piece
As noted, the top piece is designed for relatively simple removal.
- Grip the sides of the keycap's top piece with your fingers.
- Apply gentle, even pressure upwards.
- The top piece should detach from the bottom piece beneath it.
- This process can typically be done for most keys without requiring specialized tools.
Removing the Bottom Keycap Piece
The bottom piece presents more resistance compared to the top.
- The reference states that the bottom piece is "more firmly attached" to the switch's spring mechanism.
- Due to this firm attachment, removing the bottom piece often requires more care and potentially a keycap pulling tool designed to exert even upward force without damaging the switch or surrounding parts.
- Carefully pull straight up to avoid bending or breaking the stem on the switch.
| Keycap Piece | Ease of Removal (Reference) | Common Removal Method (Based on Reference) |
|---|---|---|
| Top Piece | Fairly Easily | With just your fingers |
| Bottom Piece | More Firmly Attached | Requires more effort, often needs tools |
Understanding that the Model M uses this two-part system is key to successful and safe keycap removal, ensuring you apply the appropriate method for each component. Always exercise caution to avoid damaging the key switch underneath.
