In this guide
The MX Keys S is the keyboard Logitech teams with its MX Master mice, and the two share a design brief: low profile, quiet, an aluminum key bracket, and a software layer most buyers never open. Logitech Canada lists it at $169.99 in Canadian dollars, with no markdown, in Graphite, Pale Gray and Black. Each of the three part numbers carries a US English QWERTY layout, and a Logi Bolt dongle ships in the box.
Two sensors carry the pitch: a hand-proximity sensor that switches the backlight on and an ambient light sensor that sets its brightness, both adjustable in Logi Options+. Around them sit three-device pairing and the Options+ extras, Smart Actions and Flow, which Logitech confines to recent Windows and macOS. Whether the sensors justify $169.99 comes down to how often you type in the dark and how many machines share your desk.
Our verdict
A well-documented $169.99 office keyboard for a desk that hosts several machines and gets used after dark; if neither applies, most of the price pays for sensors and switching that sit idle.
- A good fit for
- A person who types on a Mac and a Windows PC from one desk, works in dim light, and already runs Logi Options+ for an MX mouse.
- We would skip it if
- You type on one laptop in a bright room, you want a French or CSA layout, or your desk cannot spare 17 inches (43 cm) of width.
Reasons to consider it
- Backlighting controlled by a hand-proximity sensor and an ambient light sensor, adjustable in Logi Options+
- Pairs with three devices over Bluetooth Low Energy or the Logi Bolt receiver that comes in the box
- Rated for 10 days per charge on predefined settings and up to 5 months with backlighting off
The compromises
- The Bolt receiver does not work with other Logitech USB receivers, so a desk with an older Logitech mouse may need two dongles
- Smart Actions and Flow need recent Windows or macOS; other systems get basic functions only
- At 810 g and 430 mm wide it stays on the desk, and the Canadian listing is $169.99 with no markdown
What we have not verified: Key feel, noise, wobble and real-world battery life are beyond what product pages show; the recycled plastic share is Logitech's own figure and drops from 26% on Graphite to 11% on Pale Gray.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
MX Keys S Wireless Keyboard, Graphite
Three Easy-Switch channels, Bluetooth Low Energy plus a Bolt receiver in the box, and a backlight that appears when your hands do and settles to the room's light.
Before you buy: Advanced features such as Smart Actions and Flow need Windows or macOS; other systems get basic functions, and Bolt will not pair with other Logitech USB receivers.
Price checked October 15, 2026. Retailer prices can change.A full-width board with dished keys and one layout
Logitech gives the MX Keys S as 430.2 mm wide, 131.63 mm deep and 20.5 mm thick (16.94 by 5.18 by 0.81 inches), at 810 grams. The product page sells it as the full-size board, with the MX Keys Mini named as the answer for anyone short of desk space. The keys are described as spherically dished so the fingertip settles into the centre, and Logitech credits increased key stability for less noise.
On layout, Logitech's Canadian page lists all three colours as English US (QWERTY) keyboard only, with no French or Canadian multilingual part number, so a buyer who types in French with a CSA layout will not find one here. The supported systems are Windows 10 and 11, macOS 10.15 and later, Linux, ChromeOS, iPadOS 14 and later, and Android 8.0 and later. Only Windows and macOS get the full Logi Options+ feature set; elsewhere Logitech promises basic functions without the software.
Sensors that decide when the backlight is worth its power
The S in the name is mostly about two sensors. The hand-proximity sensor turns the backlight on as your hands approach, and the ambient light sensor adjusts its brightness, with duration and level adjustable in Logi Options+. The battery rating is written around that: up to 10 days per charge on predefined settings, and up to 5 months with backlighting off. Both figures carry the usual note that results vary with use.
The cell is a 1500 mAh lithium polymer pack, recharged over USB-C, with an on/off switch and two indicator lights for Caps Lock and battery. The lead in the box has a USB-A plug on the far end, so a laptop with only USB-C sockets will need a C-to-C cable of its own. Read plainly, a person who leaves the backlight on charges the keyboard every week or two, and a person who turns it off will forget the cable exists.
Bluetooth, Bolt, and the receiver that will not mix
The keyboard connects over Bluetooth Low Energy or over the Logi Bolt receiver in the box, and Easy-Switch stores three devices so one key press moves typing from a laptop to a desktop to a tablet. Range is quoted at 10 metres. Logitech states that the keyboard is not compatible with its other USB receivers, which matters on a desk where an older Logitech mouse still runs on its own dongle: that mouse keeps its receiver or moves to Bluetooth. A Flow-enabled Logitech mouse can share the cursor across computers with this keyboard.
For a compact alternative, Logitech's Pebble Keys 2 K380s is 279 mm wide, runs on two AAA cells for a rated 36 months, connects over Bluetooth, and is listed at $44.99, marked down from $59.99. The Bolt receiver works with it but is not included. The K380s suits a laptop that travels; the MX Keys S suits a desk with a monitor on it.
One year of coverage, 30 days to return, 26% recycled plastic
Logitech covers the MX Keys S hardware for one year, and orders placed with Logitech can be returned for free within 30 days; standard shipping on the Logitech store is free as well. The box holds the keyboard, the Bolt receiver, the USB-A to USB-C charging lead and the documentation. Amazon.ca's buy box, sold and shipped by Amazon.ca, shows the same $169.99 as Logitech, so price does not decide between the two.
On materials, Logitech reports that the Graphite keyboard is 26% certified post-consumer recycled plastic, against 11% for Pale Gray and 15% for Black, excluding packaging and the printed wiring assembly. The key module bracket is made with low-carbon aluminum, and the packaging paper comes from FSC certified sources. None of that changes how the keyboard types, but it is more disclosure than most keyboard makers publish, and it sits on the same page as the price.
Skip it if your desk has one machine and a window
The MX Keys S charges for three things: the backlight sensors, the three-device switching, and the Options+ automation. A person who types on one laptop under daylight uses none of them. Against the Pebble Keys 2 K380s at its $59.99 regular price, that is $110 left for a mouse or a monitor arm, and the current $44.99 listing for the K380s widens the gap to $125.
Walk away as well if you need a French or CSA layout, if 17 inches (43 cm) of keyboard will not fit between your monitor and the edge of the desk, or if your setup runs Linux and you were counting on Smart Actions. The board is at its best on a shared desk with a Mac and a PC, an MX mouse already talking to Logi Options+, and a lamp that goes off before the work does.
