# KEY-ID FIDO U2F: How to Remove the Green LED



The [KEY-ID FIDO U2F security keys](http://www.key-id.com/key-id-fido-u2f-security-key-online-security/) are a nice alternative to [YubiKey 4 Nano](https://www.yubico.com/product/yubikey-4-series/#yubikey-4-nano) because they cost only $12 instead of $50. However they include a green LED that is always enabled which makes it unsuitable for a permanent installation. In this video I explain how to open the device and remove the LED.

Here is [a great overview of the most popular FIDO U2F security keys](https://github.com/hillbrad/U2FReviews). And [this blog post has useful technical insight into the Key-ID key](https://www.imperialviolet.org/2017/10/08/securitykeytest.html).
