I know it's a vent but if you want to think about advice....Many kids are done with naps by 2.5 -- yes, even if they need them. Consider adjusting her nighttime sleep routines so she goes to bed earlier. Yep, it's work and takes time and effort, but it has to be done at some point.
It's a good sign if she slept in a regular bed that one night, but be prepared; there may be many other nights when she gets up and down and up and down just because she can. Normal. Gettiing mad at her or fussing at her will not make her stop. What worked for us was that I started out sitting in the room with one hand lightly on her and not talking (at all! Don't interact) until she was asleep. After a while I could move to sit in the hallway outside her bedroom door with the door cracked so she could see I was there. (Got a lot of reading done, too.) Then I eventually would leave but only stay in the hallway about 10 minutes and leave while she was still a bit awake. That progressed to her just going to bed and my not having to be visible. It was gradual and I think that's why it stuck and wasn't full of drama. It can work but takes a lot of patience; however, it seemed to build confidence in our daughter that we were indeed there and not vanishing. It also is crucial not to talk or interact, and if a child gets up you guide her right back to bed with a hand on her shoulder but without speaking. You may have to do this multiple times in one night. But if you talk or scold, she sees it as interacting and it becomes a game to get your attention by getting up again. Make it all totally silent and boring so there is no payoff in her mind.
If she has a doorknob that can be locked from inside her room please remove that doorknob ASAP -- it's a safety hazard! If there is a fire or any other reason you need to rush to get to her, that doorknob is a danger to her. I'm glad it broke -- get rid of it now and get one that does not lock at all. You shouldn't be locking her in from the outside, either -- in a young kid's mind that's kind of like the adult is vanishing.
Regarding her supposedly great napping at day care -- either she's so tired there from play that she does nap (and you can't necessarily replicate that tiredness at home) OR she really isn't napping as much as they claim or as much as you think. She may be staying quietly on that mat but it doesn't mean she's conked out truly sleeping each day.
If you really want to try seeing if she'll nap on weekend at home, rather than giving up naps: It's possible she is just very used to the daycare routine and nap (or just lying down time) is part of that and accepted by her as the routine. Try to be sure she has a routine on weekends too, very set and structured and the same each day, and that the weekend nap is the same time of day as the daycare nap, etc. Have a naptime routine like you have a bedtime routine so you prepare her over a while for naptime coming like you'd prepare her for bed.
It's great that you removed the crib since she was climbing. So many parents don't get rid of the crib when kids climb, and instead rely on those crib "nets" that are a tangling hazard. My friend's daughter at age 2 climbed to the top rail of her (non-netted) crib and fell and broke her arm badly - it's a long way down for a small kid from the raised top rail of a crib!
