Is a used BlackBerry Key2 worth buying for the keyboard?

For most people, no — a used BlackBerry Key2 is not worth buying in 2026 as a daily phone just for the keyboard. Its physical keyboard is still excellent, but the phone is old enough that you should expect compromises with software support, app compatibility, battery life, and network compatibility.

It can still be worth buying if you want it mainly as a niche typing device, a distraction-free backup phone, or a collector’s item. If that’s your use case, the keyboard is the main reason to get one.

If you do buy one, check:

• Battery health — old batteries are often worn out, and finding high-quality replacement batteries can be difficult.
• Carrier compatibility / VoLTE support — some modern networks require specific VoLTE profiles, and older BlackBerry devices can struggle to work reliably.
• App needs — many mainstream Android apps now require newer Android versions, so verify the apps you depend on still run on the Key2 before buying.

So the short answer is: yes for keyboard enthusiasts and light/offline use; no for most people who want a reliable modern smartphone.
