Rental Property Rekey Planning for Landlords

Why rekeying belongs in the turnover routine

When a tenant moves out, an unknown number of keys leave with them. Some were returned, some were copied, some were handed to relatives, cleaners, or friends over the years. Even the most honest former tenant may not be able to tell you how many exist. The next tenant moves in with no way of knowing who else could open the door.

Rekeying solves this simply. It changes the internal pins of the lock cylinder so that old keys no longer work and new keys do. The door, the lock body, and the hardware stay in place. The cost in effort is small compared with the risk it removes, and it gives every new tenant a clean start.

Treating rekeying as a standard step in turnover, like cleaning and touch up painting, makes it predictable. It also helps if something goes wrong later. If a tenant reports a problem, you can say with confidence that the locks were changed before they moved in. Many property managers find that this routine saves them awkward conversations.

There is a fairness angle as well. A tenant who pays rent for a home deserves to know that no stranger holds a key to it. Saying so at move in, plainly and without drama, builds trust. Tenants often mention it when they renew, because the sense of safety is part of what they are paying for, even when they never say so aloud.

What rekeying does and does not do

Rekeying makes old keys useless and creates new ones, but it does not repair a damaged lock, replace a worn door, or fix a weak frame. If a lock is already failing, rekeying may only delay the day it needs replacement. A locksmith can usually tell you which situation you are in when they look at it.

It also does not change who has access through other means. A lockbox with a code, a smart lock with stored codes, a gate code, or a garage opener each need attention on their own. A tenant who left may still know a code that opens the building or a shed. The plan should list every entry method, not only the keyed locks.

The article on how rekeying changes who can enter explains the idea in plain terms, and lock replacement or rekeying helps you decide which fits a given door.

It also helps to understand that rekeying keeps the same lock brand and style. If you want a different look, a stronger lock, or a feature such as a keypad, that is a replacement. Some owners use turnover as a chance to upgrade worn hardware in the same visit, since the door is already empty and the schedule already includes the locksmith.

Build a lock inventory for every unit

Planning begins with knowing what you have. For each unit, list every door that locks: front, back, side, garage entry, balcony, storage room, mailbox, and any gate or shared entrance you control. Note the type of lock, the brand if you can tell, and the condition. A short spreadsheet or a page in a binder is enough.

Record how many keys exist for each lock and who holds them. Include the ones you keep in a key box or on a board. Note which locks are keyed alike. If a property uses a mix of brands, that matters, because not all brands can be rekeyed to match.

An inventory lets you plan sensibly. You can see which units share a key system, which locks are old, and where hardware varies. It also saves time on every visit, because the locksmith can plan parts and time. The related lock audit checklist for landlords gives a framework for doing this walk through.

Add a column for the last date each lock was serviced and any known quirks, such as a front door that sticks in wet weather or a back lock that needs a gentle turn. These small notes save repeat diagnoses. They also help a new manager pick up where the previous one left off, which matters when properties change hands or staff move on.

Decide how many keys per tenant

Before you rekey, decide how many keys each unit gets. Think about the number of adults in the unit, how many doors they need, and what your lease says. A typical approach is one key per adult, and one spare held by the owner or manager. Some owners hold none, and some hold a master set.

Too many keys cause trouble. Every extra key is one more copy that might be lost. Too few cause trouble too, because tenants may copy keys on their own to fill the gap, and those copies are outside your records.

Whatever number you choose, write it in the lease or a move in sheet, and have the tenant sign for keys received. When the tenant leaves, count the keys back. If a key is missing, you know that before the new tenant arrives, and you can handle it properly. See key handover checklist for managers for a model.

Think about maintenance staff and vendors. A plumber, an electrician, or a cleaning crew may need entry. Decide how they will get in without a permanent key: a supervised visit, a manager escort, or a code that expires. Record each arrangement so you can remove it afterward. Every access method you hand out is something you must later take back.

Keep an eye on the seasons, too. Many rental markets turn over heavily in summer, when leases end together and several units need work in the same weeks. Booking rekey visits early for those peak weeks avoids the squeeze, and it keeps your move in dates reliable. A short list of expected move outs, shared with your locksmith, is all it takes.

If a unit is likely to be vacant for a while, keep the keys secured and note who has entered. An empty unit with a key sitting in an open office is an easy source of trouble.

Timing the work between tenants

The right time to rekey is after the old tenant has left and before the new one arrives. It is simplest when the unit is empty. If the previous tenant is still moving things out, wait until they have returned keys and left. If the new tenant is arriving soon, schedule the work early enough to leave margin for the unexpected.

Allow time for testing. After rekeying, every key should be tried in every lock it should open, and the doors should be checked for smooth operation. If a lock turns out to be worn, there should be time to replace it. Do not schedule the work for the hour before move in.

If you manage many units, plan ahead by building a calendar of expected turnovers and giving your locksmith notice. A steady relationship makes scheduling easier. Orlando Locksmith works with owners and managers across Central Florida, and the service page on tenant turnover rekey describes this kind of work.

Communicate the schedule to the incoming tenant. Tell them when the locks were changed and how many keys they will receive. If something goes wrong and the locksmith must return, they should know what to expect. A short written note that confirms the date and the key count prevents confusion at the door on move in day.

Keyed alike, individually keyed, or master keyed

Landlords with several doors per unit often choose to key all the locks in a unit alike, so a tenant uses one key for every door. That is convenient and reduces the number of keys to track. It means a lost key opens everything, so the benefit has to be weighed.

Landlords with many units may want a master key system, in which each unit has its own key and a master key opens all of them. This helps maintenance and emergency access. It also raises the stakes, because a lost master key affects every unit. Systems of this kind need careful records. Property manager master key systems and master key terms explain the vocabulary.

Not all locks can be master keyed. Some basic locks cannot, and mixing brands adds complexity. A locksmith can tell you what is possible with the hardware you have, and whether a particular layout makes sense for your property.

For multi family buildings, remember the shared doors. Entrances, laundry rooms, trash rooms, mail rooms, and pool gates all carry their own keys. Rekeying a unit does nothing about a common door that dozens of past tenants have copied. Decide when to change those, and plan for notifying current residents when you do, so nobody is shut out.

Short term rentals and frequent turnover

If a unit turns over often, as with vacation rentals, rekeying every time is impractical. Other tools help. Keypad locks and smart locks let you change codes without changing keys. A lockbox can hold a key with a changeable code. Each of these has its own risks, such as codes that are shared, batteries that fail, and guests who write the code on the door.

A good plan for frequent turnover changes codes between guests, tracks who has access, and rekeys the physical lock on a regular schedule or after a problem. See short term rental lock management basics and lockbox and keyless entry for rental hosts for ideas.

For companies that manage many vacation properties, lock planning for vacation rental companies looks at scale. In all cases, keep a backup plan for when the technology fails.

Guest behavior is the wild card in short term rentals. Some leave doors propped open, some share codes with friends, and some forget to lock up. Clear instructions at check in, a note inside the door, and a check at checkout cut down on these problems. Consider a schedule for changing codes and a plan for what happens if a lock fails in the middle of a stay.

Know what the law and your lease say

Rules about changing locks in rentals vary. Some places require landlords to change or rekey between tenants, and some set expectations on notice, key copies, and tenant changes. Leases often add their own terms. This page cannot tell you what applies to your property, and a locksmith cannot either. Ask your attorney, your local housing authority, or your property management association.

Do the same for tenants who want to change locks themselves. Many leases forbid it without permission, and some rules require that the landlord keep a key. A clear, fair policy that is explained at move in avoids disputes. The general concepts are in landlord and tenant lock changes explained in general terms.

If a tenant reports a lost key or a concern about safety, respond promptly and in writing. Delay on a lock issue can turn a small matter into a large one. A written record of the request and the response protects both sides.

Pay attention to the timing of any notice you owe tenants. If you plan to rekey a unit that is occupied, for instance after a security concern, the rules about entry and notice may apply. Ask the right authority rather than guessing, and document what you did and why. Good paperwork protects you and respects the people who live in the property.

What the locksmith visit looks like

You call and describe the property, the number of doors, and what you need. Authority is checked before any lock is changed, which may include proof that you own or manage the property. The work and price are explained before work begins. The finished work is tested with you, or with the person you send, trying each key in each lock.

Ask the locksmith to label the keys by door if you want, and to give you the key count. Keep a copy of the invoice with the date and the units. If a lock is worn or damaged, discuss replacement while the locksmith is there, so the unit is ready on time.

For properties with multiple units, ask whether work can be grouped to reduce visits. Planning a batch of rekeys across several vacant units on one day is a sensible way to work. The service page on rekeying describes the service, and move in lock changes covers a related need.

Ask what the locksmith needs from you in advance. Access to the unit, a list of doors, any known problem locks, and the number of keys wanted are the usual items. Having the unit empty and clear around doors speeds up the work. If you cannot be there, send a person who can approve the work and test the locks.

Bring up the matter of future copies with the locksmith as well. Ask whether the new keys can be marked or ordered only through an approved account, and what happens if a tenant wants an extra. Having a clear answer in advance lets you tell tenants where to go for a copy, instead of leaving them to find a shop on their own.

If a lock is stubborn during the visit, ask the locksmith to explain what they found. A worn cylinder, a loose mounting, or corrosion from humid weather can all affect how well a lock rekeys. Hearing the reason helps you decide whether to replace that lock now or plan to do so at the next turnover.

Keeping records that actually help

A record is only useful if it is simple and current. For each unit, keep the date of the last rekey, the number of keys made, who received them, and when they were returned. Note any locks replaced. Keep invoices.

Store keys securely. A locked key cabinet with labeled hooks, using codes instead of unit numbers, is better than a drawer. Limit who can open it. Sign keys out and in. If you use a lockbox for vendors, track the code and change it when needed.

Go over the plan once a year. Check that all units have been rekeyed on schedule, that no keys are unaccounted for, and that the policy still fits the property. A small amount of regular attention keeps the system healthy and spares you from dramatic fixes when something goes wrong.

Think of the records as a safety net rather than a chore. When a tenant says they never received a key, when a lock fails, or when a neighbor claims a stranger had a key, your notes give you facts. Without them, every dispute becomes a matter of memory. With them, you can answer calmly and fix the actual problem.
