What to Do With Old Keys After a Move

The pile on the kitchen counter

Every move produces the same small mystery. A bowl or drawer ends up holding a handful of keys, and nobody is quite sure which door each one fits. Some belong to the place you left, some to the new one, a few to a storage unit, a car you sold or a relative's house. Before deciding anything, it helps to sort them into piles.

Start by laying them out on a table in good light. Group them by shape and brand stamped on the head, then by purpose as sensible you can. Label each group with a piece of tape or a small tag. This takes ten minutes of patient looking, and it prevents the common mistake of throwing away a key you will need or holding on to one you should have returned.

Do not guess. A key that looks like your old front door key might open nothing you still own, or it might be the spare to your current mailbox. Test any uncertain key only on locks that you own or are authorized to use. If you rent, keys belong to the property owner, and the guidance on landlord and tenant lock changes explains who decides what.

A helpful trick is to photograph the pile before sorting, then photograph each labeled group. The pictures act as a handy catalog you can consult later, when you wonder whether the small silver key belongs to the shed or the mailbox. They also help if you ever need to describe a key over the phone to someone who cannot see it.

Keys to the home you left

If you rented, the keys to your old place almost certainly have to go back to the landlord or property manager. The lease usually says how and when, and the move out inspection is the normal moment. Returning every copy, including the spare you cut yourself, is a tidy way to end your responsibility for the property.

Get something in writing when you hand them over. A short message or receipt listing how many keys, fobs, mailbox keys and garage remotes you returned protects you if someone later claims a key is missing. Photographing the keys on the table before you hand them over takes a minute and gives you a record with a date.

If you owned the home and sold it, the keys go to the new owner or the agent at closing, along with any codes, remotes and gate fobs. Do not keep a spare out of habit. A former owner who holds a working key creates a worry for the buyer and a liability for you. If anything was lost along the way, tell the new owner so they can decide whether to rekey.

If the landlord asks you to leave the keys somewhere, such as inside the unit or in a drop box, confirm that arrangement in writing before you do it. A key left in a vacant unit with no record is a key nobody can account for, and that kind of ambiguity is where disputes about deposits and responsibility tend to begin.

The new home is the bigger concern

When you move into a place, you have no idea who still holds a copy of its keys. Previous tenants, former owners, cleaners, contractors, agents, neighbors who watered plants and relatives of those people may all have had one at some point. Most of them are harmless, but you cannot know, and a change of locks is the only way to be sure.

A rekey changes the inside of the lock so the old keys no longer work and a new key does. It is usually simpler and less costly than replacing the hardware, and the lock keeps its appearance. Our page on move in lock changes describes the usual choices, and how rekeying changes who can enter explains what happens inside.

Ideally the lock work happens before you spend your first night, or as soon after as you can arrange it. If you live in a condo or apartment, the doors you control may be limited, and building access is controlled by management. Ask what you are allowed to change, and do not alter anything without permission where a lease or association applies.

• Ask the seller or landlord how many keys were issued and how many you received.
• Count and label every key you were given on the day of the move.
• Rekey or change the locks you control as early as you can.
• Ask building management about shared entry points, gates and mailboxes.
• Keep a record of which key opens which door in a safe place.

Old keys that open things you still own

Not every key in the pile is dead weight. Your storage unit, your car, a safe deposit box, a shed or a relative's door may still depend on keys in that bowl. Identify those carefully, and keep them in a clearly labeled place. A key you cannot identify is a nuisance later, because you cannot tell whether it is important.

For keys you want to keep, consider whether you have a spare. A single copy of a car key or a safe key is a risk. If you have one, make a spare now rather than after it vanishes. Our guide to planning spare keys for a household can help you decide how many you need and where they should go.

If you hold keys that belong to other people, such as a friend's home, a neighbor's apartment or a relative's storage, give them back or confirm they still want you to hold them. After a move, the arrangement may no longer make sense. A short call clears the question and avoids a misplaced key causing worry later.

Keep the sorted keys of the home you plan to keep somewhere organized, such as a small labeled box, until you are certain about each one. Once you have tested them, put the daily keys on a ring and the occasional ones, for the shed or storage, on a separate hook. Splitting the ring makes the daily set lighter and easier to handle.

Keys that other people hold for you

Before you move, think about who has your keys. A neighbor who feeds the cat, a cleaner, a dog walker, a friend who checked on the house, a relative who kept a spare for emergencies, a contractor who finished work last month. Every one of those copies is a loose end, and most people hold them for years without a second thought.

Make a list and contact each person. Ask them to return the key in person, or confirm that it has been destroyed. If you are leaving a rental, tell them the lease is ending so they do not try to use it. If you are staying in the home but changing locks, tell them the old key will stop working and ask whether they still need access.

If a key cannot be recovered, that is the moment rekeying earns its cost. You do not have to chase anyone or worry about a lost copy, because the old keys simply stop working. Plan new keys for the people who need them, and treat the handover as a fresh start with a clear record of who holds what.

What to do with keys that no longer open anything

Once you are sure a key opens nothing you own, you have a choice. You can keep it as a memento, store it in a drawer, recycle it, or dispose of it. Brass keys can often be recycled as scrap, and some local collection points take small metal items. Check how your local service handles it, since rules vary.

If the key came from a place where you do not want a stranger to find it, such as a home you left, an office or a business, destroying it is a sensible precaution. Bending a brass key repeatedly or cutting it with tin snips makes it useless. Use eye protection, since small metal pieces can fly. Throwing away an intact key with a label on it is the one thing to avoid.

Do not label keys with an address. A tag that says a street name and a unit number turns a lost key into an invitation. Use a color code, an initial or a private numbering system that only you understand. This applies to keys you keep as well as keys you carry.

Fobs, remotes, cards and codes

Modern homes use more than metal keys. Gate fobs, garage remotes, building cards, key cards for the pool and entry codes all need the same treatment. Return those that belong to the property, and ask the manager to deactivate the ones you hand back so they no longer work.

If you receive new fobs and cards, make sure they are registered to you and that the old ones for your unit have been deactivated. In multi unit buildings, a former resident's fob may still open the lobby until management removes it. It is reasonable to ask management when old credentials were turned off.

Entry codes work the same way. A keypad lock may still hold the former occupants' codes. Reset or delete them as soon as you have access, and note the settings in a safe place. Our guide on condo entry and building access explains how shared entry systems are usually managed.

Remember also that moving is a time when strangers come and go. Movers, delivery crews, cleaners and painters may all have been in the home while doors stood open. That is another reason to look over the locks, check that every door still latches, and keep an eye on the keys you handed out during the move.

Doing the move in order: a short sequence

The order of tasks helps. First, collect every key and credential from the old home. Second, return or hand over what belongs to others and get a written record. Third, sort what remains into keep, return, and destroy piles. Fourth, secure the new home. Fifth, make a plan for spares.

On move in day, count the keys you were given and test each one in its lock before the previous owner or manager leaves. A key that fails the test is easier to resolve while the person is still available. Write down any problems, then take a photo of each lock for your records.

Our moving day lock checklist lays out the sequence in more detail. Treat it as a guide and adjust for your own situation, for example a house, a townhome, an apartment or a business unit. Each has different decision makers and different doors.

A note for families, roommates and shared homes

When several adults share a home, keys multiply. Each person may have a copy of the front door, the mailbox, a gate fob and a parking tag. A move is the right time to reset that arrangement, because everyone expects change, and the old habits have not set yet.

Decide who needs which key and how many copies exist. Write it down. If someone leaves the household, collect their keys the day they go, and consider rekeying if there was friction. Our pages on keys and roommates and replacing locks after a roommate leaves go through the common situations.

Children and teenagers need keys at some point, and a lost key is a fact of life. Plan for it by keeping a clean spare somewhere safe and by giving younger family members a key that opens only the doors they must use. A calm routine around keys means fewer panicked evenings and fewer calls from a porch.

When to call for lock help

Call a locksmith if the new home has locks that stick, keys that do not match, doors that will not latch, or any sign that someone has tampered with the entry. Also call if you want every exterior lock keyed alike, or if the previous occupant left you a disorganized mix of keys. Describe what you have and where, and the team will explain the options and the price before work starts.

Ownership or authority is checked before any rekeying or opening. If you are a new owner, a closing statement or deed is a typical document. If you are a tenant, the lease and the owner's approval may be needed. This protects you and the property, and it is an ordinary part of the work.

After the work, test every lock with the customer present. A properly rekeyed lock should accept the new key smoothly and refuse the old one, and the door should close and latch normally. For a broader look at the work, read our rekeying service page, which explains how the process fits with other services.

Plan the practical bits too. Boxes get lost on moving day, so carry the key bowl with you rather than packing it on the truck. Keep the new home's keys on a ring you can find easily, and give one to each adult who lives there before the first wave of errands begins.

Things people forget

People remember the front door and forget the others. A side door, a sliding door, a garage entry, a gate, a mailbox, a pool enclosure and a storage closet can all hold keys that were given out. Walk around the property and check each opening with the question, who might have a key to this?

Another overlooked item is the garage door opener. Remotes and keypads can be shared by many, and a new owner may want to reset the codes. The garage is a common path into a home, so it deserves attention just like a front door. See garage entry door lock basics for the typical weak spots.

Finally, remember digital life. If the former owner left a smart lock or a doorbell camera tied to an account, make sure the account is transferred or removed. A device that still answers to someone else's phone is a security problem that no key change fixes. Reset the hardware and set up your own account.
