The MX Keys is the keyboard people quietly refuse to give up. Those slightly dished, low-profile keys with the perforated metal top plate have spoiled a generation of writers, coders and spreadsheet wranglers. The problem has always been the sticker price. The good news: because so many were bought for offices and home setups that have since been reshuffled, the second-hand market is full of them, and a gently used one types exactly like a new one for a fraction of the cost.

Why second-hand is not “second best”
A keyboard is one of the safest things you can buy used, and the MX Keys is built better than most. The chassis is a single piece of steel with a perforated aluminium face, so it does not flex, creak or yellow the way a budget plastic board does after a couple of years. There is no battery you can wear out in the usual sense either: the internal cell recharges over USB-C and is rated for hundreds of cycles, so a unit that is a few years old will still hold a charge for weeks of normal use, and months if you leave the backlight off.
The scissor switches are the real story. They are sealed, low-travel mechanisms with very few moving parts, which means they do not collect grit or develop the mushy double-press problems that plague cheaper membrane boards. A previous owner can type a million words on an MX Keys and the key feel barely changes. What you are really inheriting is a keyboard that has already survived its early-life failure window, with someone else having paid full price for the privilege.
A keyboard does not get tired. It gets a little shiny on the spacebar. The MX Keys was overbuilt on day one, so buying one used just means someone else absorbed the depreciation.
The savings are real
The MX Keys sits at the premium end of Logitech’s range when new, and that premium evaporates fast on the used market. Because it was sold in such volume to businesses and prosumers, supply is healthy, which keeps second-hand prices honest. A clean used unit, or a refurbished one with a fresh receiver, commonly lands well below the cost of a new board, and that gap is wide enough to put a decent palm rest, a USB-C cable and still leave change in your pocket. For the full-size MX Keys versus the compact MX Keys Mini, expect the standard full-size board to be the cheaper of the two used, simply because more were made.
New vs used, side by side
| Brand new | Used / refurbished | |
|---|---|---|
| Price | Full premium | Roughly 20-60% less |
| Key feel | Pristine scissor switches | Effectively identical |
| Receiver | Logi Bolt in box | Confirm it is included |
| Backlight wear | Full brightness | No meaningful fade |
| Cosmetics | Flawless | Possible shine on common keys |
| Environmental cost | All-new manufacturing CO2 | Already paid by first owner |
The five-minute checklist before you pay
- Receiver or Bluetooth? Ask whether the original Logi Bolt USB receiver is included. If it is missing you can still pair over Bluetooth, but a replacement Bolt receiver is an extra purchase and not every dongle is cross-compatible.
- Every key in the photos. Ask for a clear shot of the whole top plate. Look for missing keycaps, especially the larger ones like Enter, Backspace and the spacebar, which are the hardest to source.
- USB-C charging confirmed. Ask the seller to confirm the board charges and the battery indicator climbs. A swollen or dead cell is rare but worth ruling out.
- Backlight works. The proximity-sensing backlight is a signature feature. Ask the seller to confirm the keys light up when a hand approaches in a dim room.
- Mac or Windows layout. There is an MX Keys for Mac variant with Mac-specific legends. Decide which you want; a Windows board still works on a Mac but the printed symbols will not all match.
- The flip-out feet. Cheap to overlook, annoying to lose. Confirm both rear tilt legs are present and click into place.
You have more protection than you think
If you buy from a business or a professional refurbisher rather than a private individual, the Australian Consumer Law still applies. That means the keyboard must be of acceptable quality and match its description, regardless of the lower used price. A dead board that was sold as working is your grounds for a remedy. Buying through a platform with buyer protection adds another layer: keep the listing, the messages and your payment record, and you have a clear paper trail if the keyboard arrives not as promised.

Red flags to walk away from
- “Receiver lost, never tried Bluetooth.” Two unknowns stacked together. If neither connection method is confirmed working, you are buying a paperweight on hope.
- Sticky or shiny keys described as “minor.” Heavy spacebar shine or a tacky residue can point to a board that lived a hard, un-cleaned life. Fine at the right price, not at near-new money.
- No photo of the underside. The model and layout are printed on the base. A seller who will not show it may be hiding a regional or Mac variant you did not want.
- Battery “needs to stay plugged in.” That is a worn internal cell. The whole appeal of this board is weeks of wireless life, so this defeats the purpose.
- Price that is suspiciously close to new. If a used board is only a few dollars under retail, just buy new and keep the warranty.
Frequently asked questions
Will a used MX Keys work with my Mac and my PC at the same time? Yes. The Easy-Switch keys let it pair with up to three devices and flip between them with a single press, so one board can drive your work laptop, home desktop and tablet in turn.
Do I need the Logi Options+ software? No, the keyboard types fine out of the box. The software only adds extras like custom key actions and per-app settings, and it is a free download, so a missing disc or link is never a reason to pass on a listing.
How long does the battery last on an older unit? With the backlight off, a healthy MX Keys runs for months between charges; with backlight on, around ten days of typical use. A few years of age barely dents this because the cell is rated for many hundreds of cycles.
Is the full-size MX Keys or the MX Keys Mini better used? The full-size board is usually cheaper second-hand and gives you a number pad. The Mini frees up desk space for a mouse. Choose by your desk, not by the price difference, which is small.
The bottom line
The MX Keys earns its loyal following because it was engineered to outlast the desk it sits on. That durability is exactly why buying one used is such a comfortable call: the parts most likely to fail do not, the typing feel is preserved, and the only real variable is cosmetic shine you will stop noticing within a day. Run the five-minute checklist, confirm the receiver and the charge, and you walk away with a genuinely premium keyboard for a mid-range price, while keeping one more solid device out of Australia’s e-waste pile.
