Logitech MX Keys S: problems, parts and running costs
Checked: 2026-10-19
Summary
The most common complaints are the dim white-only backlight, keys loosening or falling off with no spare parts, and Bluetooth typing lag on some MacBooks, alongside no dongle storage and no adjustable typing angle. There are no consumables; the only extra cost is the optional $20 palm rest. It is strong value at $100 or less and weak above $130.
Common problems and fixes
- Keys loosening or falling off — one owner reports some keys started to “giggle” or completely fell off, with “absolutely no spare parts” available. [7]
- Bluetooth typing lag on some MacBooks — a 2023 thread reports lag over Bluetooth, worse when the Mac is plugged into power; Windows and Linux worked fine, and one user fixed it by changing the USB power source. [9]
- No dongle storage — the Logi Bolt receiver has no storage slot inside the keyboard and can be lost easily. [2][4][10]
- No adjustable typing angle — the keyboard is a fixed low profile with no retractable feet. [2][4]
- Short key travel and shaky keycaps — one owner found the travel too short even for a low-profile board, the keycaps shaky, and a small rattle on the 0 and Enter keys. [8]
Parts and consumables
- Optional MX Palm Rest — $20 add-on. [4]
Yearly running cost
No consumables and no subscriptions; the only extra cost is the optional $20 palm rest, and the only running cost is charging over USB-C. No annual dollar figure is given. [4][10]
When it is a good buy
At $100 or less it is strong value for the typing feel, quietness, 3-device switching and battery life. From $101 to $115 it is good value for multi-device Windows and macOS users. From $116 to $130 it is fair; compare against the original MX Keys, the MX Keys Mini if no numpad is needed, and mechanical alternatives such as Logitech’s MX Mechanical. Above $130 it is weak unless the low-profile scissor feel and the Logi Options+ ecosystem are specifically required. [2][3][4][6]
Prices seen at retailers: Logitech’s own US store listed it at $119.99 in October 2026, marked down from $129.99; Newegg at $107.39 and Walmart at $129 in 2024; Walmart and Best Buy at $120 in 2026-09; Lenovo at $129.99; the 2023 MSRP was $109.99. [1][2][3][10]
The original MX Keys, MX Keys Mini or MX Mechanical are the better choices when you want a lower price, a smaller footprint or mechanical switches. [3][4][6]
