Frequently Asked Questions
Common questions about our letter / mailbox lost key service.
In most cases, yes. Our locksmiths are trained in non-destructive entry and can open many letter box locks without damage. Where the lock needs to be drilled, we carry replacement cylinders.
Sometimes we can decode the existing lock and cut a new key. In other cases, we rekey or replace the cylinder — we'll advise on the best option for your lock type.
Yes. We work on communal mail systems and can liaise with building management to coordinate access.
We offer same-day service in most cases and can often attend within a few hours of your call.
Yes. In most cases we can replace just the cylinder, which is far more cost-effective than replacing the entire post box.
