How to tell the IR missile to unlock?

[TKim1018]

I was playing the nuclear thunder event and I keep getting into trouble because my aim 9 locks onto a flare, or a friendly jet, etc.
Is there a specific keybind to tell the missile to start seeking again and to get off whatever heat source it’s currently looking at (reset)?
I’m currently just switching to the aim 7 and then back to the aim 9, but that’s pretty clumsy and I assume there’s a better way to do it. Can anyone help?

Thanks!!

I believe default on keyboard is alt+x

Do you know what it’s called specifically?

Air to air weapon lock? I think that’s what it is, if you look it up you might be able to find what you have it bound to as of now (if it’s even bound)

It’s the same key bind for activating the lock.
