A missing key can be an access problem and a security concern. Depending on your existing lock and circumstances, rekeying or a lock change may be worth discussing.
Things to consider
- Do you have another way to access the property?
- Could someone else use the missing key to enter?
Your next step
Discuss access and whether rekeying or replacement is suitable.
