What changes when the keys are lost, not just locked inside
A lost-key case raises a different question: once access is restored, is the property still secure enough to leave unchanged? That depends on where the keys might have been lost, whether anything on the keyring identifies the address, and whether you feel comfortable continuing with the same lock.
For foreigners, that decision can be hard to make under pressure. A practical service should not only help you get back in, but also help you think clearly about the follow-up.
