lots of things do glow under UV light. So, sure, why not.
WHY the lever would glow needs some contrivance; weather it's because it was used by someone covered in some fluorescent dust before and they left a hand-print, or contains some of the right impurities in the concrete or stucco or whatever.

What about instead of UV torch, a heat sensor (infrared?) and the switch having a current and hight resistance is actually warmer?

Why not have the door open automatically at night time due to movement or heat. Your protagonist ie I assume is a mammal and therefore hot, a sensor could detect him/her/it when close enough, and the door would open automatically. If the bad guys/things/whatevers are reptiles the door would not open. Alternatively just have a movement sensor near to the door, that is only activated at night time. Or why not have your protagonist have an electronic pass card to hand, or chip inserted in the skin, to activate a coded gate. OR the gate could be sound activated, sing a song or something in the right key, which might not work if your protagonist is tone deaf, a tuning fork might help the tone deaf, or not.

Why? Deserts are freaking cold at night, so heat sensor would work like a charm
