I think DH took my key bizarre behaviour.

[Oreoo]

So my front door key went missing off my key ring , it's really tight so can't have fallen off. Someone would have had to taken it off. I know it was there yesterday morning as I entered the house after a night shift I've come home early. I've asked DH and DD as I had to enter through the back door they both denied it. I then said to DH we will have to change the locks, he then says it will cost a lot of money knowing things have been tight for me.

DH then went downstairs messing with the front door, he then came back up with a new key. Somehow he had a spare barrel lock ready to go and to install. He's never mentioned he's had anything like this.
It's so weird, I can't wrap my head around why he might have taken the key but I think it's him. My keys are in my pocket all night shift. Can any MNers offer an explanation ?

Someone took your key with the possibility of you not being able to get into your own house after work?

I would not be happy.

Perhaps your daughter should be getting into trouble if she has taken & key & then lost it!

There's something really odd about this. Why would you go straight to changing the locks if you'd lost a single, presumably unmarked key? If somebody found it, they wouldn't know what it was for anyway...

He wanted the locks changed for some reason, and wanted to blame you for being the reason why.

Ask to see his key.

If he says some bollocks about 'he threw it away' then there is no doubt he took your key because for some reason he didn't have a key of his own.

DD can't be responsible, because DH went straight into replacing the barrel, rather than saying, 'I'll pop into town and cut you a new one.' if you had 'lost' yours.

Me too. Don't understand any of it. And what's a rental house got to do with anything?!

Maybe another AI. I understand the rental house to mean OP own another house they rent out, and they have various DIY things related to being landlords, such as a lock change.

Why would you change your locks over one lost single key lost anywhere. I've lost loads. You would have to walk miles and miles and try every door until you found the door.

I think you need to discuss the supervision of your DD when she plays outside. If she is too young to have a key, she should probably have some supervision when she plays. At the very least, if your DH is hard of hearing, how is he going to hear if she needs help when she's out?

If she's old enough to play outside without supervision, she should have a key. It's scary to get locked out. If she borrowed your key and lost it, it probably is because she didn't have a secure place to put it on her person when playing outside. Some trainer shoes have a little zip pocket for a housekey. Or, you can get her shorts with a small, hidden key pocket. Or a wristband with a little key holder.
