TL;DR
A smart lock is the better choice for recurring cleaning access because it gives you a code you can revoke instantly and a log showing exactly when the door opened. A lockbox is cheaper, needs no power, and never has a connectivity problem, but it protects a physical key that can be copied and tells you nothing about who used it.
Lockbox vs Smart Lock at a Glance
| Factor | Lockbox | Smart lock |
|---|---|---|
| What it controls | A physical key | The lock itself |
| Revoking access | Change the combination, recover the key | Delete the code, instant |
| Access log | None | Timestamped entries |
| Per-person codes | No | Yes |
| Time-limited access | No | Yes on most models |
| Power dependency | None | Batteries, sometimes a network |
| Copying risk | A key can be copied | No physical key to copy |
| Purchase cost | Low | Several times higher |
| Failure mode | Jammed dial, seized shackle | Dead batteries, network outage |
Retail pricing puts a shackled metal lockbox in the region of $15 to $50, while consumer smart locks generally run $80 to $350 depending on features and finish. Both work. The choice usually comes down to whether you value the audit trail more than the simplicity, and whether the door already has a deadbolt a smart lock can replace.
Why Is a Smart Lock Usually Better for Recurring Access?
A smart lock is usually better because it separates access from a physical object. You issue a named code to the service, you see a timestamp when it is used, and you delete it in seconds when the arrangement ends. A lockbox protects a key that can be copied, and nothing tells you if it was.
The audit trail is the part households underrate. When a question comes up about whether anyone entered on a given day, a log answers it in ten seconds and a lockbox leaves you guessing.
Per-person codes matter too. If the company sends different crew members, a single shared code makes every entry anonymous, while individual codes make the log meaningful. Setting them up properly is covered in how to set up a guest door code.
Where a Lockbox Still Wins
Cost is the obvious one. A solid shackled lockbox is inexpensive compared with a smart lock, and it needs no batteries, no application, and no network.
Compatibility is the practical one. Not every door takes a smart lock. Older mortise locks, some multipoint patio doors, apartment doors governed by a building policy, and doors with unusual backsets can all rule one out. A lockbox works on any door with a key.
Reliability is the underrated one. A lockbox has no dead batteries, no firmware update at the wrong moment, and no outage. When a smart lock fails on a visit day, the crew is standing outside, and that is exactly the scenario in what happens when no one is home.

How to Use a Lockbox Safely
Mount it out of casual sight, ideally on a fixed fitting rather than hanging on the door handle where it advertises itself. A lockbox on the front door knob tells anyone walking past that a key is inside.
Use a shackled model with a metal body rather than a soft plastic one, and set a combination that is not a house number, a birth year, or a repeated digit. Change the combination when the service ends, and change it if anyone outside the arrangement ever learns it.
Put a single key inside and nothing else. No address tag, no fob, no spare for a second property. A key with an address attached turns a small loss into a large one.
Finally, check it in cold and wet weather. Combination dials seize, and a lockbox that will not open on a January morning is a lockout in a different costume.
How to Use a Smart Lock Safely
Create a dedicated code for the service rather than sharing your own, and name it clearly in the application so the log is readable months later.
Use scheduling if the lock supports it. Limiting the code to the visit day and a window around it means the code is inert the rest of the week, which is far stronger than a permanent code nobody thinks about.
Keep batteries fresh and set a reminder well before the low-battery warning becomes urgent. Most smart lock lockouts are battery lockouts. Keep a mechanical override key somewhere sensible off site, such as with a neighbor or a family member, so a dead lock is an inconvenience rather than a locksmith call.
Review the log occasionally, not obsessively. A monthly glance at entry times against your schedule is enough to notice something out of place.
Which One Should You Choose?
Choose a smart lock if the door supports one, you want a log and a revocable code, and the household is comfortable maintaining batteries and an application. That is most recurring cleaning arrangements.
Choose a lockbox if the door cannot take a smart lock, if the property is a rental where the lock cannot be changed, if the visit is a one-time clean, or if you simply want a solution with no power and no software in it.
Choose neither if someone is reliably home. Being present removes the entire access problem, though it introduces others around workflow and privacy that are worth weighing separately.
Whatever you choose, keep a written record of who holds what, and revoke everything when the service ends. Lost keys and compromised codes are covered in what to do if a key or code goes missing, and the access terms themselves should be documented as part of hiring a cleaning service rather than agreed casually at the door.
Households booking recurring house cleaning services should also ask how the company records and stores access details, since that is as much a part of trust as background-checked crews.
FAQ
Is a lockbox safe for a house cleaner?
Reasonably safe when it is a shackled metal model, mounted out of casual sight rather than on the door handle, set to a combination that is not a house number or birth year, and holding one unlabeled key. Change the combination when the service ends.
Should I give my cleaner a smart lock code?
Yes, a dedicated code rather than your own, named clearly in the application so the access log stays readable. Where the lock supports scheduling, limit the code to the visit day and a window around it so it is inert the rest of the week.
What happens if the smart lock battery dies on cleaning day?
The crew cannot get in, and most companies treat that as a lockout with the fee stated in the agreement. Set a battery reminder well before the low warning becomes urgent, and keep a mechanical override key off site with a neighbor or family member.
Can a house key from a lockbox be copied?
Physically, yes. Any key can be copied, and a lockbox gives you no way to know whether it was. That is the main reason a smart lock code, which can be revoked instantly and leaves a timestamped log, is generally the stronger option for recurring access.
How do I revoke a cleaner's access when service ends?
With a smart lock, delete the code yourself and check the log to confirm it is gone. With a lockbox, recover the key and change the combination. In both cases, confirm in writing with the company that no access remains, and rekey the lock if any key is unaccounted for.
Do cleaning companies prefer a code or a key?
Most prefer a code, because codes cannot be lost, mixed up between properties, or left in a vehicle. A code also removes the company's responsibility for holding a physical key to your home, which is a liability they generally have no wish to carry.
Pick the one your door supports, then treat the code or key like a credential and revoke it on the way out. Every home is different, so the real number depends on size, condition, and what you want covered. Get a quote and we will walk you through it.
