[sudo-access] omni front door latch getting sticky

today i got a call that the front door latch wasn't working right. I came to the space and checked it out, and it's definitely getting sticky - trying to open the door right after activating the latch release sometimes doesn't work. Trying a second time works. I fiddled with the solenoid latch and tried to identify the problem but i can't see anything specific that's going wrong. This latch was just purchased a couple of months ago and i'm guessing it was hundreds of dollars. It's a really fancy thing. Maybe it has a warranty? I don't see a good place to put in lubricant, and sometimes that makes things worse. So especially since this thing was fancy and expensive, i think we should be careful and do the right thing. Hopefully it's not going to get worse, but I expect that since it was fine before and now it's not, it's just going to produce more complaints. We might have to put up a sign or something. Next time I work on the front door, i'll put a louder speaker on the access system so that people can better hear the beep indicating that they should pull the door open. -jake
