Cleaning business key policy: key logs, lockboxes, smart locks and what to do when a key is lost

Why does a cleaning company need a written key policy?

A cleaning company needs a written key policy because keys are the one thing clients worry about more than the cleaning. A lost key means a stranger could have access to a home, the client pays for rekeying if you do not, and your reputation takes the hit either way. A policy written before the first key changes hands protects the client, the cleaner and you.

It also makes you look professional at the first visit. Handing a client a key receipt and explaining the lockbox option tells them you have done this before. How cleaning companies handle keys is one of the first questions careful clients ask, and “we have a procedure, here it is” is the answer that wins the job.

The order of preference

1. Smart lock or keypad with a code for your company. No physical key at all, and the client can change the code any time.
2. Lockbox at the client’s home. The key never leaves the property. You hold a combination, not a key.
3. Client lets the cleaner in. Works for clients who are home, but a no-show or a late client costs you a slot.
4. You hold the key. The last resort, and the one that needs the most procedure.

Many companies still end up holding dozens of keys. That is fine, as long as each one is tagged, logged and locked up. The rest of this guide is that procedure.

How should you receive and tag a client’s key?

Receive a key with a signed receipt, tag it with a code that means nothing to an outsider, and record the code and the client in a list kept away from the keys. A key that says “Dana Smith, 42 Oak Street” on the tag is a burglary kit if it falls out of a pocket.

Key receipt

Print two copies, one for the client and one for the client’s file. It should include:

• Client name and address (on the receipt, not on the tag)
• Number of keys and what they open (front door, garage, gate, mailbox)
• Alarm code, if any, and whether you may disarm and rearm it
• Date received and the name of the person who received it
• The key code you assigned, so the client can quote it
• A line stating your lost key procedure (see below) and that keys are returned within 2 business days of ending service

Tagging

• Use a numbered tag or a short code such as “K-117”. No names, no addresses, no company logo on the tag.
• Keep the master list (code, client, address, alarm notes) in your scheduling software or a password-protected file, never on paper next to the keys.
• Do not put client keys on the same ring as the cleaner’s own keys. A separate, plain ring per client, or per route for that day.
• Photograph the key and its tag on the day you receive it, so there is no dispute later about which keys you had.

If your software keeps property records, that is where the code and the alarm notes belong. Broombook, for example, stores access notes, alarm codes, parking and pets on each property and shows them to the cleaner on the visit day, with the address and codes staying as written. See features for how property records work.

What goes in a key log, and where do you store keys?

A key log records who took which key, when, and when it came back. Store keys in a locked cabinet in a locked room, or a key safe, with one person responsible for handing them out. The log is what turns “I think Luis had it” into a fact.

Rules for the day

• Keys go out in the morning for that day’s route only, and come back the same day. No keys stay in cars or homes overnight.
• The cleaner keeps the ring on their body (a belt clip or a zipped pocket), never loose in a caddy or a car.
• Lock the vehicle every time, even for a two-minute trip to the trunk.
• At check-in, the person in charge counts the keys against the log before signing the cleaner out for the day.
• Audit the cabinet monthly: every key on the list is in the cabinet or signed out, and every key in the cabinet is on the list.

Solo owners

If you are the only cleaner, you still need the log, just shorter: the key list, a photo of each, and a note of which keys are in your bag today. The log protects you the day a client accuses you of losing a key you never had.

How do lockboxes work for a cleaning company?

A lockbox is a small combination safe that hangs on the client’s door knob or mounts to a wall. The client keeps a spare key inside, you get the combination, and the key never leaves the property. For most residential cleaners this is the best balance of security and convenience, and it costs the client less than a single rekeying.

The Master Lock 5400D, a common choice, is an over-the-knob box with a set-your-own 4-digit combination, listed at $44.92 on Master Lock’s site at the time of writing. Wall-mounted models bolt to the house and are harder to remove, which some clients prefer. Either way the box is the client’s property, so let them buy it, or buy it for them and bill it at cost.

Lockbox procedure

1. Client sets the combination, not you. They can change it whenever they like, including the day you stop working for them.
2. Store the combination in the property record in your software, not on a sticky note and never on the box.
3. Scramble the dials after every use. A box left on the last digit is an open door. Make this a checklist item.
4. Return the key to the box before leaving, and check the box is closed. Photo of the closed box if you want proof.
5. Ask the client to change the combination when a cleaner leaves your company, and again if a phone that held the code is lost.

Script: suggesting a lockbox to a new client

“Most of our clients use a lockbox: a small combination safe on the door with a spare key inside. That way we never carry your key, you can change the code any time, and if you ever cancel there’s nothing to return. They’re about $45 and I can bring one to the first visit if you’d like.”

Should you ask clients for smart lock codes instead of keys?

Yes, when the client already has one or is open to installing one. A smart lock gives your company its own code, the client can see when it was used, and nobody has to hand over metal. It is the cleanest answer to the key question.

The two features that matter for cleaning are per-user codes and a history. Schlage describes its Encode line as letting owners grant access with customized access codes and view lock history from the app; the August Wi-Fi Smart Lock fits over the existing deadbolt so the client’s current keys still work, with auto-lock and an optional keypad for guest codes. Other brands offer the same basics. What you need from any of them:

• One code per cleaner, or at least one per company. Shared codes cannot tell you who entered. If the client will only create one code, record who used it in your key log.
• A schedule on the code where possible. Many locks let the owner limit a code to certain days and hours. A code that only works Tuesday 8 am to 5 pm is a smaller risk than one that works always.
• Auto-lock on. Cleaners forget doors. A lock that relocks itself after a minute removes the most common complaint.
• A plan for dead batteries. Ask where the physical key or the backup power contact is, and note it in the property record.

Code hygiene

Treat codes like keys: store them only in the property record, never text them around, and ask the client to delete a cleaner’s code the day that cleaner leaves. Keep a list of which clients have given which cleaner a code so you can do that in one afternoon. If your software translates job notes for cleaners, make sure codes and addresses stay as written; Broombook’s translation leaves codes, addresses and names untouched for that reason.

What do you do when a cleaner loses a client’s key?

Tell the client the same day, before they find out another way; offer to pay for rekeying; and write down exactly what happened. A lost key handled in the open is a bad afternoon. A lost key hidden for a week is a lost client and possibly a police matter.

The procedure

1. Search for 30 minutes, not longer. The car, the caddy, the last three homes, the cleaner’s pockets and bag. Call the previous client and ask them to check their counter. In our experience, most keys are found here.
2. Call the client. Not a text. Say what was lost, when you noticed, that the tag carries only a code and no address, and what you will do about it.
3. Offer rekeying at your cost. Rekeying changes the pins so the lost key no longer works; it is cheaper than replacing the lock. Let the client choose their locksmith, or offer yours, and pay the invoice directly or refund it.
4. Write an incident report. Date, cleaner, key code, where it was last seen, who was notified and when, what you paid. Keep it with the client file.
5. Decide on the cleaner. A first loss with a candid report is a retraining conversation. A second one, or a loss the cleaner hid, is a different conversation.

Script: the lost key call

“Dana, it’s Maria from Bright Corner. I need to tell you something straight away. Ana can’t find your front door key after today’s visit. The tag only has a code on it, no name or address, so nobody can connect it to your home, but I don’t want you worrying. I’d like to pay to have your lock rekeyed this week. Would you like to use your own locksmith, or shall I book ours for tomorrow morning?”

If the client asks for more

Some clients will want new locks rather than rekeying, or a credit for the stress. Paying for new locks on one door is usually cheaper than losing a recurring client. Say yes to reasonable requests, in writing, and note what you agreed. If the request is unreasonable (a full home alarm system, for instance), explain what your policy and your insurance cover and hold that line politely.

Who pays when a key is lost, and does insurance cover it?

You pay, in the first instance, and your insurance may reimburse you if you have the right endorsement. Standard general liability policies often exclude property in your care, custody or control, and a client’s key is exactly that, so check before you assume you are covered.

NEXT Insurance describes lost key coverage as an endorsement to general liability that can help pay to rekey locks or replace hardware when client keys in your care are lost or damaged, and explains that the care, custody or control gap in standard policies is why the endorsement exists. Insureon’s article on lost key insurance adds three points worth knowing: the coverage usually extends to the contractor and its employees, it does not cover consequential losses (its example is computers stolen from a building left unlocked while the keys were missing), and it does not cover an employee who intentionally takes a key, which is what a janitorial bond is for.

Ask your agent three questions: is there a care, custody or control exclusion on my policy, can I add a lost key endorsement and at what limit, and what is the deductible. Then put the answer in your key policy so you know in advance what you will pay out of pocket. The guides to cleaning business insurance and the janitorial bond explain the policies themselves. None of this is insurance advice; policies differ by carrier and state, so read your own wording.

How do you return keys when service ends?

Return keys within two business days of the last visit, in person or by tracked courier, against a signed receipt, and ask the client to confirm they have changed any lockbox combination or smart lock code you held. End the relationship with the same care you started it.

1. Pull the key from the cabinet, check the tag against the master list, and mark it “returned” with the date.
2. Hand it back in person when you can, with a two-line receipt both of you sign. If you mail it, use a tracked service and send the tracking number.
3. Delete the alarm code, lockbox combination and smart lock code from the property record, or mark them retired.
4. Text the client: “Your key is back with you and we’ve removed your codes from our records. Please change your lockbox code when you have a moment.”
5. Keep the receipt in the closed client file. Disputes about keys can surface months later.

The same steps apply when you end service yourself. The guide to firing a cleaning client covers the notice and the final bill; the key return is the last item on that list. If a client never collects a key, keep it locked and logged, send two written reminders, and keep the record of both.

Put the policy in writing for clients

A short “Keys and access” paragraph in your service agreement covers the lot: how keys are tagged and stored, that you recommend a lockbox or smart lock, what you do when a key is lost, and when keys are returned. Add it to the cleaning contract template, and pair it with a lockout clause in your cancellation policy so a cleaner who arrives to a locked door with no key and no code is paid for the trip.
