Lost house keys
Lost keys raise two questions: how to get inside and whether the existing locks should remain in use.

Lost house keys — renew entry while address the missing-key risk, with the glass specification, dimensions and access route agreed.
Consider which doors the keys operate and whether someone could link them to the address. A replacement or rekeying enquiry can then cover the affected locks.
The detail that matters
Must every lock in the home change?
The scope should follow the missing keys and their possible exposure, rather than including unrelated locks automatically.

Can I keep using a spare key?
A spare may restore access, but it does not prevent the missing key from operating an unchanged lock.
What should I include in this enquiry?
Identify the entrance, postcode, system make if known and the authorised site contact. Describe the affected functions, user numbers and any alternative access; keep PINs and administrator passwords out of the enquiry.
