Missing transistor after changing joysticks

Hi everyone, so as the title says, I must have accidentally hit this transistor while desoldering the left analog stick. Unfortunately, it fell off and I couldn’t find it, and there are no schematics for this controller online. Can anyone help?

That’s a resistor a 0402, i measured mine on a bdm-030 and it reads 100k
