Dell KM5221W Pro Wireless Keyboard & Mouse - QWERTY UK Black
The Dell KM5221W Pro Wireless Keyboard & Mouse is a full-sized RF 2.4GHz wireless combo designed for office and home workers who need a quiet, secure, and long-lasting input solution. It suits those who work across multiple monitors or share workspace with others, thanks to adjustable DPI settings, 128-bit AES encryption, and an ambidextrous mouse design. A single USB receiver connects both devices, and the combo is backed by a three-year advanced exchange warranty.
Why this product
Up to 36 months battery life
The keyboard runs on 2 x AAA batteries and the mouse on 1 x AA, with Dell claiming up to 36 months of use before replacement — reducing the frequency of battery changes in a busy workspace.
128-bit AES encryption on keystrokes
All keyboard input is protected with 128-bit AES encryption over the 2.4GHz wireless link, helping to keep typed data secure from wireless interception.
12 programmable function keys
Each of the F1–F12 keys can be assigned to frequently used applications, folders or functions, cutting the number of steps needed for routine tasks.
Four selectable DPI settings
The optical mouse offers four DPI levels — 1000, 1600 (default), 2400 and 4000 — adjustable through Dell Peripheral Manager software to match different monitor resolutions and working styles.
Quiet typing for shared spaces
The plunger-switch keyboard is designed to minimise noise, making it suitable for open-plan offices or taking calls without disrupting those nearby.
Three-year advanced exchange warranty
The combo is covered by Dell's limited warranty with an advanced exchange programme for three years, meaning a replacement is dispatched before the faulty unit is returned.

Best for
- Office workers on long days who want a quiet keyboard, minimal battery changes, and a secure wireless connection over 2.4GHz.
- Left- and right-handed users — the symmetrically designed ambidextrous mouse suits both without requiring a separate purchase.
- Multi-monitor setups — four selectable DPI levels let the mouse be tuned to match different screen resolutions in the same workspace.
- Security-conscious typists who require 128-bit AES encryption on wireless keyboard input.
- Buyers wanting long-term cover — the three-year advanced exchange warranty means a replacement ships quickly if the combo develops a fault.
Trade-offs
- Bluetooth-only environments — this combo uses a 2.4GHz USB receiver exclusively; there is no Bluetooth pairing option.
- Wired-only setups — there is no wired mode; the keyboard and mouse operate solely over the wireless receiver.
- Users needing more than three mouse buttons — the mouse provides three buttons in total, with only one programmable.
- QWERTY layouts other than UK — this unit is specifically the UK QWERTY layout and is not suited to users who require a different regional keyboard.

Easily navigate across monitors of varying resolutions at home or in the office.
