A swivel case for the YubiKey 5C NFC, 5C NFC FIPS and Security Key C NFC. The key sits inside the case and turns on the keyring hole: swing the case round and it covers the gold contacts, swing it back and the key is ready to plug in. There is no cap to come off and get lost, and the steel wire keyring it comes with screws shut, so it will not open in a pocket the way a split ring can.
Why put a YubiKey in a case
A security key spends its life on a keyring, rubbing against car keys and coins. The key itself is tough, but the exposed contacts and the touch sensor take the wear. A case keeps them covered while the key is in your pocket and costs less than replacing a key that has stopped reading reliably.
It also makes keys easy to tell apart. If you carry a primary and a backup key, or you hand keys out to staff, a different colour for each person or role saves plugging in the wrong one. This listing is the blue case; the other colours are on the swatches above.
Fit, tested on the real keys
We test-fitted this case on the YubiKey 5C NFC and Security Key C NFC (the FIPS versions share the same body): slide on and off, the keyring loop, plugging into a USB port, the touch sensor and an NFC tap. Every check passed, and the key held firmly in the case while still coming out easily. NFC works through the case, so tapping the key on a phone does not mean taking it out first.
It is printed for the full-size NFC key body only. It will not fit the YubiKey 5 Nano, 5C Nano, 5Ci or the Bio series, which are different shapes. If your key is a YubiKey 5 NFC, you want the YubiKey 5 NFC case instead.
Made and posted by us
Each case is 3D printed by IronSights (case size 4.0) and posted from our office as a large letter. If you order it with a key, the key ships from our warehouse partner and the case arrives separately in its own letter, so do not worry if they turn up on different days.
