<human>: Could you distill the essence of the text into 1-3 sentences?

I often go to stay the night at my boyfriend's house (he lives about 5 mins away), leaving my three housemates in our house. They tend to bolt the door as soon as I'm gone, on top of the sturdy wooden door with  double lock that we already have. They say the bold adds extra security, but it's not at all substantial and if someone made it past the double lock they'd easily get through the bolt.

The problem is that it means I cannot get back into my own house until one of them unbolts it. This has been a problem when I've been back early before, and one of them has had to get up to let me in. The other night I was at my boyfriend's and realised I needed to be back for something, but couldn't because I didn't want to wake any of them up, and they'd be pissed if I had.

I've told them that I get uneasy knowing that I won't be able to get into the house if I need to, without relying on them to let me in. They counter it by saying the bolt makes them feel happier at night (we live in a slightly rough area, but it's not too bad for crime). I know it's my own fault for staying away at night and being up late, but how do we resolve this situation? Anyone else had this issue with housemates before? Thanks
<bot>: Housemates are really paranoid about security, ends up with me not being able to get back into my own house. What do?
