Recommended tools for some keys
Optional but handy: the spudger lifts the key without scratching or bending the mechanism, and the thin blade of the flat screwdriver unhooks the plastic hinge and helps clip it back in.

On these keyboards, this genuine MX Keys key takes the place of the official one: same scissor mechanism and mounting, with a legend and finish that may differ slightly.
Where is the Num Lock key and what does it do?
On a full-size Logitech MX Keys, the Num Lock key, marked with a padlock bearing a “1”, sits at the top left of the keypad, above the 7. Each press switches the keypad between numbers and navigation (arrows, Home, End, Page Up and Down). The keyboard has no Num Lock light: Logi Options+ can show its status on screen.
About the Num Lock replacement key
An incomplete keypad slows down every figure you type: this Num Lock key for the MX Keys, shipped with its hinge, replaces the missing one. Genuine Logitech and pre-owned, the Num Lock key was removed from another keyboard; only the rubber dome is not included.
Compatibility
This Num Lock keycap fits the full-size MX Keys (MX Keys, MX Keys S and MX Keys for Mac), the only ones with a numeric keypad: the MX Keys Mini has none, so there is no place for it there. The legend is that of the QWERTZ (CH) layout.
The Num Lock key: position, size and wear
Only the full-size MX Keys has a numeric keypad; its keys take bursts of one-handed presses whenever figures are keyed in. With no metal wire under a one-unit cap, the Num Lock key rests entirely on its scissor hinge. A press at an angle, a fingernail slipped underneath or a vigorous clean is enough to tear one of its clips.
How to install it
No tools needed. Lift what is left of the old Num Lock key by one corner, straight up, clear away any pieces of hinge, clip the supplied hinge flat onto its anchor points, then set the new cap on top and press the centre until it clicks.
Num Lock key — questions
- How do I turn on the number pad (Num Lock) on an MX Keys?
- On a full-size Logitech MX Keys, the Num Lock key, marked with a padlock bearing a “1”, sits at the top left of the keypad, above the 7. Each press switches the keypad between numbers and navigation (arrows, Home, End, Page Up and Down). The keyboard has no Num Lock light: Logi Options+ can show its status on screen.
- Does this Num Lock keycap fit my Logitech MX Keys?
- Yes, if it is a full-size MX Keys (MX Keys, MX Keys S and MX Keys for Mac) in the QWERTZ (CH) layout. The MX Keys Mini has no numeric keypad.
- Is the hinge included with the Num Lock key?
- Yes. The Num Lock key ships with its scissor hinge, so it also fixes a key that lost its clip. The rubber dome under the Num Lock key is not included: yours stays on the keyboard, and a spare can be ordered separately if it is damaged.
- I changed the cap on the Num Lock key, but it still types nothing — what now?
- If the Num Lock key was unresponsive rather than physically broken, the fault usually lies in its scissor hinge, included here, or in the rubber dome underneath, sold separately. Replace the hinge first, then the dome if the Num Lock key still feels mushy.
