Why You Should Rekey Your Locks After Moving Into a New Home or Commercial Building

At B-SAFE Lock & Key, we've helped homeowners, business owners, property managers, and commercial facilities throughout Minneapolis and the Twin Cities secure their properties since 1972. One of the first recommendations we make after moving into a new home or commercial building is to rekey the existing locks so you know exactly who has access. The closing papers are signed, the boxes are stacked, and someone hands you a set of keys. Before those keys become part of your daily routine, consider who else may still have a copy. Learning how to rekey locks after moving is one of the most practical first steps you can take to make a new home feel like your own.

A previous owner may have given keys to relatives, neighbors, contractors, dog walkers, cleaners, or tenants. Even if every key was returned at closing, there is no reliable way to know how many copies were made over the years. Rekeying changes which key operates the lock without necessarily replacing the entire lock, giving you control over access from day one.

Why Rekeying Should Be an Early Move-In Priority

Rekeying is different from changing locks. When a lock is rekeyed, a locksmith adjusts the internal key configuration so the old key no longer works and a new key is required. The existing lock hardware stays on the door if it is in good condition and compatible with rekeying.

For many new homeowners, this is the most efficient option. You can keep quality deadbolts and handlesets already installed on the home while removing access associated with prior keys. It can also make daily life simpler when several exterior doors can be set to work with one new key, provided the hardware is compatible.

The priority is usually exterior access points: front, back, side, patio, garage entry, and doors connecting an attached garage to the home. Do not overlook a detached garage, storage shed, gate, or common-area door if you have responsibility for its security. A locksmith can help determine which locks should be included and which hardware may need a different solution.

How to Rekey Locks After Moving: A Practical Plan

Start by gathering every key you received at closing, including keys tagged for doors, garages, mailboxes, sheds, and cabinets. Keep them organized until the work is complete. While the previous keys will no longer work on rekeyed doors, they can help a locksmith identify which lock each key currently operates.

Next, walk the property and make a list of every door or opening that needs controlled access. Pay attention to doors that are easy to miss during a busy move, such as a basement walkout, utility-room entrance, side service door, or rear gate. If a door has two locks, such as a knob lock and a deadbolt, both should be evaluated. A new key for one lock does not secure the other.

Then inspect the visible condition of the hardware. Look for loose handles, sticking deadbolts, keys that are difficult to turn, rust, misaligned strike plates, or doors that do not close smoothly. Rekeying a worn or poorly functioning lock may restore key control, but it will not correct mechanical damage, poor installation, or a weak door frame.

When you schedule a professional rekey, explain how many exterior doors you have and whether you want one key to operate multiple locks. A locksmith can identify compatible lock cylinders, create new keys, test each opening, and advise you if a lock should be repaired or replaced instead. For Minneapolis and Twin Cities homeowners, B-Safe Lock & Key can assess the hardware already on the property and provide a practical recommendation based on its condition and your access needs.

Finally, decide who should receive keys after the rekey is complete. Keep the number of copies limited and intentional. A spare key held by a trusted family member may be useful, but avoid leaving a key in an obvious hiding place outside the home. Record where authorized copies are kept, especially if several adults, caregivers, or contractors need occasional access.

When Rekeying Is the Right Choice

Rekeying works well when the lock hardware is reliable, properly installed, and offers the level of security you want. It is often a smart choice for newer deadbolts, quality lever handles, and compatible locksets that simply need a new key configuration.

It is also useful when you want convenience. A home can accumulate a surprising number of keys over time: one for the front door, another for the back door, a third for the garage entry, and another for the shed. Where compatible, keying those locks alike can reduce the number of keys you carry without reducing control over who has access.

Landlords and property managers can use the same approach between occupants. Rekeying after a tenant changes helps establish a clear new access point without replacing functional hardware throughout the property. For multi-unit or larger properties, a master-key system may be worth discussing so authorized management access can be organized without giving one key unrestricted access everywhere.

When Replacing the Lock Makes More Sense

A rekey is not always the best answer. If the lock is damaged, outdated, frequently jams, or has been installed incorrectly, replacement may be the safer long-term investment. The same is true when the door itself has security concerns, such as a loose strike plate, weak screws, or visible gaps that keep the deadbolt from fully engaging.

Replacement may also be appropriate if you are upgrading the home’s hardware. A new homeowner may prefer a deadbolt with better durability, a keypad lock for controlled code access, or higher-security hardware for a specific entry. The right choice depends on the door, the existing lock preparation, the people who need access, and how the home is used.

Electronic locks deserve special attention after a move. Changing the physical key, if the lock has one, is only part of the job. Remove old user codes, reset administrator credentials according to the manufacturer’s instructions, review any app-based access, and create new codes for household members. If you are unsure whether a prior owner’s access has been removed, professional service can prevent a small oversight from becoming an ongoing concern.

Do Not Forget These Move-In Access Points

Some locks fall outside the usual front-door conversation. A secure move-in plan should account for the places that protect tools, vehicles, documents, or secondary entry to the home.

• Garage service doors and the door between an attached garage and the house

• Patio, sliding-door, basement, and side entrances

• Detached garages, sheds, gates, and outdoor storage areas

• Interior locks for offices, storage rooms, or rooms containing sensitive items

• Safes, lockboxes, and filing cabinets, especially when codes or keys were left behind

Mailbox access is a separate matter. Some mailbox locks are controlled by a property manager, homeowners association, or postal service arrangement. Confirm who is responsible before changing or servicing that lock.

A Few Questions to Ask Your Locksmith

Before the appointment, it helps to know whether you want all exterior doors keyed alike or whether certain doors should remain separate. For example, some homeowners want a different key for a detached garage or workshop. Others want one household key for convenience and a separate key for a private office or storage space.

Ask whether your current locks are compatible with one key, whether the deadbolts and strike plates are operating correctly, and whether any doors need hardware repairs before rekeying. If the home has specialty or high-security lock cylinders, mention that when scheduling so the right service approach can be planned.

You can also ask for enough new keys for the people who truly need them. It is easier to start with a clear key plan than to distribute untracked copies later.

Make the Home Yours Before the Boxes Are Gone

A new address comes with plenty of tasks, but rekeying belongs near the top of the list because it creates a clean starting point for your household. Whether the existing hardware only needs new keys or the doors need a broader upgrade, a professional inspection helps ensure the locks operate reliably and the people entering your home are the people you have chosen.
