Trunk Issue, Not Vallet Button?

[ISrookie]

Don't know what happened all of a sudden my trunk won't open, button on the back- nothing. Unlock on my key FOB- nothing, unlock on the dash-nothing. Opens when I use the physical key, or the "girlfriend lever" depressed and reset vallet button in glove box still nothing. Plus it came out of nowhere, no dead battery or anything proceeding it, if anyone has any ideas before I take it to lexus please let me know, any insight appreciated, thanks
