I got in the habit of having my hand on my key when I close my door as well. If I’m at an office with a prox badge, I’ll touch it once as a habit. It’s saved my bacon more than once as I realized I was about to go to the loo (which required a badge) while my badge was back at my desk behind this door I’m about to close (which needs a badge). Bonus for the times when my phone’s not with me.

Furthering that OCD, I also try to have my phone my in hand when I leave the desk. I sustained a back injury a year ago and I’m still getting it addressed; if I have a relapse I can’t go get my phone but must call out from the floor and wait for help. It’s less embarrassing if that’s with a phone.
