Should You Lock Your Pet Door at Night? How Curfew Mode Works


The short answer: Yes — leaving a pet door unlocked at night invites wildlife like coyotes, raccoons, and stray cats into your home. A pet door with curfew mode solves this by letting your pet come back inside after dark while preventing them from going back out — so they stay safe without you having to manually lock and unlock the door.

If you let your cat or dog roam during the day, you probably worry about what happens after dark. Coyotes, raccoons, and other wildlife are most active at night, and an unlocked pet door is an open highway in both directions. But locking the door entirely means your pet might be stuck outside if they don't come home before curfew.

A pet door with a built-in curfew feature offers a smarter solution: it automatically switches to "in-only" mode at night, so your pet can always get back inside, but can't wander back out into danger.

Why Nighttime Is the Biggest Risk for Outdoor Pets

In suburban and rural areas across the United States, nighttime brings real dangers for free-roaming pets:

  • Coyotes are increasingly common in suburban neighborhoods and routinely prey on small dogs and cats after dark
  • Raccoons and skunks are nocturnal and often enter homes through unlocked pet doors
  • Owls and other predators pose a threat to small pets, especially cats and small-breed dogs
  • Vehicles are harder for pets to see at night, increasing the risk of accidents
  • Temperature drops can be dangerous for short-haired breeds left outside

The traditional solution — manually locking the pet door every night — has an obvious flaw: if your pet is still outside when you lock it, they're stuck out there. And if you leave it unlocked, wildlife can come in.

How a Pet Door with Curfew Mode Works

The iGuardPaw smart pet door offers a curfew feature through its auto mode (P2). Here's how it works:

  1. You set allowed access hours using the door's button panel (e.g., 7:00 AM – 8:00 PM)
  2. During allowed hours: Both the inner and outer sensors are active. Your pet (wearing a collar sensor) can freely go in and out
  3. After curfew: The inner sensor turns off. Only the outer sensor stays active. This means your pet can push the door to come back inside, but cannot go back outside
  4. The next morning, when allowed hours begin again, both sensors reactivate and your pet can go out freely

This "in-only" logic is the key difference. It's not just a timed lock — it's a smart curfew that always gives your pet a way home.

Curfew Mode vs. Timer Mode: What's the Difference?

The iGuardPaw door offers two timed modes, and understanding the difference helps you choose the right one:

Feature Auto Mode (P2) — Curfew Timer Mode (P1)
Requires collar sensor? Yes — only collar-wearing pets can use the door No — any animal can pass through when unlocked
During allowed hours Collared pet can freely go in and out Any animal can freely go in and out
After curfew / off-hours In-only: pet can come in, but cannot go out Fully locked: nothing goes in or out
Best for Pet owners who want selective access + nighttime safety Simple on/off scheduling without pet identification
Wildlife protection Yes — only collared pets trigger unlock No — any animal can enter during open hours

Which should you choose? If you have wildlife concerns (raccoons, stray cats, coyotes), auto mode (P2) is the better choice — it keeps non-collared animals out at all times while still giving your pet a curfew. If you simply want to lock the door on a schedule and don't need pet identification, timer mode (P1) works fine.

Real-World Scenarios: How Curfew Mode Helps

Scenario 1: The Cat Who Stays Out Too Late

Your indoor-outdoor cat likes to roam during the day but you worry about coyotes at night. You set curfew hours from 7 AM to 8 PM. After 8 PM, the door switches to in-only mode. Your cat can push the door to come back inside whenever she's ready, but she can't go back out until morning. No more lying awake wondering if she's safe.

Scenario 2: The Dog Who Chases Wildlife

Your dog loves to chase raccoons and skunks after dark. With curfew mode set to end at sunset, he can come back in after doing his business, but he can't go back out to chase wildlife. You sleep peacefully knowing he's inside and the door is secured.

Scenario 3: Multi-Pet Household

You have two cats — one stays indoors, one goes outside. You put the collar sensor on the outdoor cat only. During allowed hours, the outdoor cat can come and go freely. After curfew, she can come back in but not go out. The indoor cat (no collar) can never trigger the door, so she stays safely inside at all times.

Common Questions About Pet Door Curfew Features

Can I set different curfew hours for different days?

The iGuardPaw door uses a single daily schedule — the same curfew hours apply every day. If you need different weekend hours, you can manually override using the manual lock/unlock button on the door's panel. Just remember to switch back to your normal mode afterward, or the scheduled curfew may not resume properly.

What happens if the power runs out during curfew?

The door runs on 4 AA batteries (lasting about 4 months) or a Type-C power supply. If the batteries die, the door will stop functioning. We recommend keeping fresh batteries on hand and replacing them every 3-4 months. Battery life varies depending on brand and temperature conditions.

Does curfew mode work without WiFi or an app?

Yes. The iGuardPaw door works completely offline — no WiFi, no Bluetooth, no smartphone app. You set the curfew schedule directly on the door's button panel. Once configured, it runs independently. There are no connectivity issues, no app updates, and no subscription fees.

Will my pet be able to get back in if the door is in curfew mode?

Yes — that's the whole point of curfew mode. In auto mode (P2), the outer sensor stays active even after curfew hours. When your pet approaches the door from outside, the sensor detects their collar and unlocks the door so they can push through and come inside. They just won't be able to go back out.

Can I manually lock or unlock the door outside of the curfew schedule?

Yes. The door has a manual lock/unlock button on its top panel. You can use it to temporarily override the current state — for example, to let a guest's pet through, or to lock the door during an unusual situation. Just remember to switch back to your normal mode afterward, as manual overrides don't automatically reset.

Setting Up Curfew Mode: Quick Guide

  1. Power on: Install 4 AA batteries or connect a Type-C power supply. The door turns on automatically when powered.
  2. Set the current time: Enter P4 mode on the button panel and set the current time. This is essential — without the correct time, curfew scheduling won't work.
  3. Choose auto mode (P2): This activates collar-sensing with curfew support.
  4. Set your curfew hours: Define the time window when your pet is allowed to go outside.
  5. Put the collar sensor on your pet: The sensor (about 3cm in diameter) attaches to your pet's collar and triggers the door's unlock mechanism.
  6. Test it: Have your pet approach the door from both sides during allowed hours to confirm it works, then wait until curfew hours begin and test the in-only behavior.
