A lock is only as secure as the number of people who no longer live behind it. Every tenant who moves out, every contractor who finishes a job, and every agent who closes a showing walks away holding a key that still opens the door. Securing and lock changes get treated as an afterthought at the exact moments they matter most, which is whenever a property changes hands. The gap between move out and rekey is where most unauthorized access actually happens.
Over the life of a single property, dozens of people can end up holding a working key without anyone tracking it. A previous tenant, a cleaning crew, a repair technician, a listing agent showing the unit to prospective buyers, a prior owner who never returned their copy. None of these people intend harm, but intent isn't the point. A key is a key, and once it leaves the chain of custody, the owner has no reliable way of knowing who still has access. Multiply that across a portfolio, and the number of unaccounted keys in circulation is almost always higher than anyone managing the properties would guess.
Who Actually Has a Key
This is where the exposure stops being theoretical. A vacant property with unaccounted keys is a target for squatting, theft, and vandalism in a way that a properly secured one isn't. Insurers increasingly ask about lock status when a claim is filed on a vacant or recently vacated property, and a policy that assumes reasonable security measures were taken can be contested if the locks were never changed after the last person left. The cost of a rekey is small. The cost of proving negligence wasn't the cause of a break in is not.
Even properties under active, professional management aren't automatically covered. A property can be inspected on schedule and reported on accurately and still carry a key exposure nobody flagged, because inspection and lock security tend to get treated as separate line items rather than one connected process. The inspection confirms the property looks fine. It doesn't confirm who else can still walk through the front door, and that distinction is exactly where a well documented property still ends up with an undocumented risk sitting in someone's pocket.
Making Lock Changes a Standard Step, Not a Special Request
The properties that stay secure are the ones where rekeying is built into the transition checklist rather than requested after something has already gone wrong. That means a lock change at move out, a lock change at listing, and a lock change at closing, logged the same way an inspection report is logged, so there's a clear record of when the last unaccounted key stopped working. Firmhand treats securing and lock changes as a scheduled step at every transition point a property goes through, not a reactive fix ordered after a break in.
A property is never more exposed than in the window between one set of hands and the next. Closing that window early is cheaper than closing it after a claim.
