Smart Lock Codes for Cleaners and Trades

Handing out a spare key used to be the only option. Smart locks fixed that. The trouble is that most owners set up codes once and never touch them again. Then a lock dies in January, or a contractor from two summers ago can still get in.

Here is how to run smart lock access codes properly, especially at a home or cottage you are not always at.

One person, one code

Never share a code between people. Give the cleaner one code, the snow removal crew another, and each family member their own.

That way the entry log tells you exactly who came in. It also means you can delete one person's access without changing the code for everyone else.

When a job ends, delete the code the same day. An old code nobody remembers is an easy gap to miss.

Put codes on a schedule

Many locks and control systems let a code work only on certain days and times. Use that.

• A cleaner's code can work Thursdays from 9 a.m. to 1 p.m. and nowhere else.
• A trade's code can run for the two weeks of a renovation, then expire on its own.
• A property checker's code can work any day during the winter months.
• Family codes can stay on all the time.

A code that expires by itself is a code you never forget to delete.

The entry log is the real feature

Remote locking is handy. The log is what you will actually use.

Every unlock is recorded with the code that opened it and the time. You can see that the furnace technician arrived at 10:40, or that nobody came on the day the cleaner was booked.

If your insurer asks for regular checks while the cottage is empty, the log gives you a dated record of each visit.

Cold weather is where smart locks fail

The batteries in most smart locks sit on the inside of the door. That is fine in a heated house. It matters in a cottage that goes cold.

One manufacturer's spec, for example, rates the battery side of its lock to -15°C and notes that alkaline batteries stop working around freezing. Keep the building above freezing if you want the lock to work all winter.

Battery type matters too. Schlage recommends premium alkaline batteries for its electronic locks and warns that lithium batteries can fail with little warning. Alkaline batteries fade slowly, which gives the lock time to send low-battery alerts.

Three habits go a long way:

• Change the batteries every fall, before you close up.
• Keep the building heated, even at a low setting.
• Keep the mechanical key somewhere you can get to it.

Doors move with the seasons

Wood frames swell in humid summers and shrink in dry winters. Cold weatherstripping gets stiff. Either one can push the bolt against the strike plate.

A smart lock motor is small. When the bolt rubs, the motor strains, the batteries drain faster, and the bolt may stop short of fully locking. Some locks report "locked" even when the bolt never fully seated.

Two fixes help. Line up the strike plate carefully at install, so the bolt slides freely in every season. Then add a door contact, so the system knows the door is actually shut, not just that the lock tried.

Keep the lock connected

Many smart locks talk to your phone over Wi-Fi or Bluetooth. If the Wi-Fi is weak at the front door, the lock drops offline and you cannot change a code from the city.

At a cottage, we recommend connecting the lock to the alarm panel or control system instead. Then codes, the entry log, and the alarm all live in one app. Our Ajax vs DSC vs Qolsys comparison explains how each panel's app works.

The internet connection behind it matters just as much. If you are on satellite or cellular, our guide to cottage internet options explains what to plan for.

Gates and long driveways

A lock on the front door does not help if the snowplough operator cannot get past the gate. A keypad or intercom at the gate solves that. Trades can buzz in, and you can open the gate from your phone after you see who it is.

Gate codes follow the same rules as door codes: one per person, on a schedule, and deleted when the work ends.

A quick setup checklist

• One code per person, never shared.
• Schedules on every code that is not family.
• Old codes deleted the day a job ends.
• Fresh alkaline batteries every fall.
• A door contact on every door with a smart lock.
• The lock tied into the alarm or control system at properties you do not visit often.

Questions we get

What happens if the batteries die?

You use the mechanical key. With alkaline batteries, locks give a low-battery warning well ahead of time, on the lock and in the app. That is why we recommend changing them every fall rather than waiting for the alert.

Can I change codes from the city?

Yes, if the lock is connected. A lock tied into the alarm panel or control system can have codes added, scheduled, or deleted from your phone.

Do you install smart locks and access control in Wasaga Beach?

Yes. We work across Collingwood, The Blue Mountains, Thornbury, Meaford, Wasaga Beach, Creemore, Craigleith, and Clarksburg.

Can the system tell me if the door is actually closed?

Yes, with a door contact. The contact reports whether the door is open or shut, separately from whether the lock says it locked.

Set it up once, properly

A smart lock is only as good as the way its codes are managed. Get the codes, the batteries, and the door right, and it stays out of your way for years.
