Bluetooth keyboard F1-f12 keys

I have the bt-key3xl. How do I change the function keys to work as f1-f12 instead of volume control, copy controls, etc… without pressing Fn key? There is a lock icon on the f12 key but it doesn’t seem to do anything?

Hi Benjamin,

Thank you for contacting us about your keyboard. I’m sorry about the f1-f12 keys.

Unfortunately, those keys are hard coded to work as a F keys with the function buttons and as the keys your mention without it. The lock key serves to lock the screen on mobile devices.

This decision was made in the expectation that most users would be connecting the keyboard to an iOS or Android device and would find the F keys less useful, since they only work in Windows with a few exceptions, such as programs that emulate MS-Dos or Windows.

If this is a deal breaker for you, please contact us directly at with your order number, we will help with a return.

Thank you,
