building worker lost house keys - what do I do?

I've had the builders in the house for the last few weeks and they've been brilliant.

But one of the labourers has lost my house keys. They're the keys of the front door, side door and new French doors at the rear (all the keys needed to get access to the house).

Should I insist that the builder replace all the locks?

Any help would be be appreciated

Thanks

Yes, and get them changed ASAP.

It actually might be safer to replace them yourself.

Hopefully you still owe them for some remaining work and you can deduct the costs. If you change your self and try and get the costs reimbursed Id say good luck!

When you are at it go to your lock smith and get all the barrells the same, then 1 key will open all
