When a tenant hands back the keys, the property is only as secure as the number of copies still floating around. Most renters are honest, but over a lease term keys get duplicated for house sitters, dog walkers, friends, and the occasional locksmith run nobody mentioned. Rekeying at turnover is the cleanest way to guarantee that the only people who can open the doors are the ones you handed keys to today.
Rekey or replace? For turnover, rekey almost always wins
Changing a lock means buying and installing a whole new lockset. Rekeying keeps your existing hardware and simply re-pins the cylinder so the old keys no longer work and a new key does. If your deadbolts and knobs are in good shape, rekeying is faster, costs less, and lets you match several doors to a single key. We only recommend full replacement when the hardware is worn, damaged, or you are upgrading to a higher security grade.
The move-out security checklist for Houston landlords
Turnover is the one window when the unit is empty and you can reset everything at once. Rekey every exterior door — front, back, side, and the garage entry door that people forget. Pull any spare from a lockbox or fake rock and start fresh. If the property uses a keypad deadbolt, delete the old codes and issue a new master. And if the prior tenant had a mailbox key, rekey or replace that lock too, since mail theft is a real problem across Harris County.
Move-out is also when small maintenance issues surface. A tenant who quietly lived with a slow drain or a dripping line for months is not going to flag it on the way out. Owners outside our market often book emergency drain and plumbing repair or professional drain cleaning services during the same empty-unit window, because it is far easier to fix a line when no one is living over it.
What rekeying actually costs and how long it takes
For a typical single-family rental with three or four exterior locks, a rekey visit runs a fraction of the cost of new hardware and is usually done in under an hour. Keying several doors alike means one key for your turnover crew instead of a ring of mismatched copies. If you manage a portfolio, we can set up a simple system so each unit has its own key while you keep a single management key that opens everything.
Why DIY rekey kits fall short on rentals
Hardware-store rekey kits exist, but they only work on one brand at a time and assume every cylinder is in perfect condition. Rental hardware rarely is. A worn cylinder that grabs or a deadbolt that needs a shove is exactly the kind of thing a pro catches and corrects on the spot. Good physical security also pairs with good digital habits — the CISA home network security guidance is worth sharing with tenants who add smart locks, and lock grades certified by the Builders Hardware Manufacturers Association tell you which hardware will actually hold up to daily renter use.
What a professional rekey visit actually looks like
When our technician arrives for a turnover rekey, the work is quieter and quicker than most owners expect. We remove each lock cylinder, replace the pins so the old key combination is permanently retired, and cut you a fresh set of keys on the spot. While the cylinder is out, we check the deadbolt throw, the latch alignment, and the condition of the strike plate, because a turnover is the ideal moment to catch the small mechanical problems a departing tenant never mentioned. The whole visit for a typical single-family rental takes well under an hour, and you walk away holding the only working keys to the property — no waiting on a hardware order and no second trip.
Keying a multi-unit property the smart way
For owners with duplexes, fourplexes, or a small portfolio, rekeying at turnover is also a chance to bring order to a messy key situation. We can key each unit individually so a tenant key opens only their own door, while setting you up with a single management key that opens every unit you own. That arrangement means your maintenance crew carries one key instead of a confusing ring, and a lost tenant key never compromises the rest of the building. Planning the system once, at a natural turnover, saves you from rekeying piecemeal every time someone moves.
How often should rental locks be rekeyed?
The simplest rule is to rekey at every tenant change, full stop. Beyond that, rekey any time a key goes missing, after a contractor or property manager relationship ends, and immediately following any attempted break-in. Locks themselves can last many years, so you are rarely replacing hardware on this schedule — you are simply resetting who has access. Treating rekeying as a standard line item in your turnover budget, like cleaning and paint, keeps your liability low and your tenants confident that the home they just rented is genuinely theirs alone.
