How to Manage Keys for Client Properties (Register, Tags, Sign-Out)
- Coded key tags protect client privacy and prevent a lost key from exposing the property address.
- A single key register with codes, properties, clients, copies and sign-out history keeps every key accounted for.
- Signing keys in and out, storing them securely and handling losses openly keeps client trust.
A cleaning or maintenance business that services forty properties holds forty sets of keys, and each one is a promise. Lose one and the cost is a locksmith, a changed lock, an awkward phone call and, often, the client. Lose one with an address written on the tag and it is also a security problem and a privacy breach. Key management is not complicated, but it has to be done the same way every time, by everyone.
The tag never says the address
Every key gets a tag with a code and nothing else. Property 23, or a letter-number pair, or anything that means nothing to a stranger who finds it on the footpath. The code links to the address only in the register, and the register is not on the key ring. A key with an address on it is an invitation; a key with a code is a piece of metal.
The register is the whole system
One list, in a locked file or a password-protected sheet: the key code, the property it opens, the client, what the key is (front door, garage, alarm fob, gate remote), how many copies exist, where the key is kept, and the sign-out history. Nothing else is needed. If the register is right, every key can be accounted for in a minute.
Access details, alarm codes, gate codes and the like are personal information under the Privacy Act 2020. They live in the register, with access limited to the people who need them, and they are never sent in a group text or written on the job sheet.
Sign out, sign in, every time
A key leaves the safe only against a line in the register: who took it, which key, the date and time, and when it came back. Not “the crew has the keys this week”. Each key, each person, each time. In a one-person business that feels like overkill until the day a client asks when their key was last out and you can answer from the register instead of from memory.
Keep keys in one place
A key safe or lockable cabinet at the base, not in the van overnight, not in a cleaner’s bag over the weekend. Keys for the day go out in the morning and come back at night. A van that is broken into with twenty tagged keys in the glovebox is a bad day; one with coded keys and no register in it is a manageable one.
Agree the rules with the client
Write into the service agreement how keys are handled: coded tags, the register, the sign-out rule, that keys are returned on termination within a stated time, and what happens if one is lost (you pay for the lock change). Clients who see the rule up front trust the business with the key. Across 12,570 publicly posted reviews of NZ cleaning, garden and pest control businesses, responsiveness is praised in 32.4% of positive cleaning reviews and problem solving in 25.1% for cleaning, 34.6% for garden and outdoor and 38.6% for pest control. A business that can answer “where is my key” instantly, and that handled the one lost key properly, is the one that gets described that way.
When a key is lost
Tell the client the same day. Offer the lock change at your cost before they ask. Record it in the register with what happened. One lost key, handled that way, usually keeps the client. One lost key discovered by the client is a different story.
One lost key, handled that way, usually keeps the client.
Audit it
Once a month, count the keys in the safe against the register and the sign-out lines. Any key that is out without a line gets chased that day. Any property that has ended gets its keys returned and the line closed.
A register
The maintenance log, request form and key register in our resource library includes the key register in Excel with the code, property, copies, location and sign-out columns, alongside the maintenance request form and log. Free. Tag every key this week and the register is done in an afternoon.
Keys are the most literal form of trust a client hands you. Keep them where you can account for every one.
What to do on Monday
- Replace every key tag with a coded label and remove any address markings today.
- Create a key register listing each key’s code, property, client, copies and location.
- Set up a sign-out sheet so every key movement is logged before it leaves the safe.
