Getting locked outside home happens to many people at some point. It’s frustrating and can throw off your entire day. When you suddenly realize, “I locked myself out of my house,” the stress hits fast. But don’t worry. You can handle this calmly and efficiently. Let’s walk through what to do right now and how to prevent this situation in the future.
Being Locked Outside: What to Do Right Now?

Stay Calm and Assess All Entry Points
First things first—take a deep breath. Panicking won’t help when you’re locked outside apartment or house. Instead, slow down and think clearly. Walk around your home and check every possible entry point. Look at the front door, back door, and any side entrances. Don’t forget ground-floor windows—sometimes they’re open or unlocked. If you have pets, check pet doors too. You might find an unexpected way in without causing damage.
These small details can save you the trouble of calling a locksmith. Check carefully. If you find any unlocked windows, make sure they're secure before climbing in. This simple step can save you time and money.
Calling a Family Member, Roommate, or Neighbor with a Spare Key
If you don’t find any open doors or windows, think about who might have a spare key. Does your roommate, family member, or trusted neighbor have one? Calling them could solve your problem quickly. Having someone nearby with a spare key is a lifesaver when you are locked outside home. If you don’t already have this setup, consider arranging it for the future. It’s an easy way to avoid spending hours outside waiting for help.
Maybe Open the Door with a Card?
You might have heard tips about opening locked doors with a credit card or plastic card. This trick only works on spring bolt locks, not deadbolts or smart locks. Trying this on the wrong lock can damage your door or card, making things worse. So, if you’re locked out of my house, don’t rush to use this method unless you’re sure your lock supports it. It’s better to save this for emergencies and know your door hardware well.
The Importance of Having a Pre-Check Routine Before Leaving Home
Here’s a tip to stop lockouts before they happen. Before you leave, check that you have your keys or smart device in hand. Confirm the door locks behind you correctly. This simple habit can save you from saying, “I locked myself out of my house” again. Make it part of your daily routine—just like grabbing your phone or wallet. A quick pre-check keeps your day running smoothly.
Professional Solutions to Get Back Inside
If you’re locked outside apartment or house and can’t get in any other way, it’s time to call a locksmith. Professionals have the right tools and skills to open doors without damage. Though this option might cost money and take time, it’s often the safest choice. Still, you can avoid this hassle in the future by upgrading your door security with smart locks. They offer more control and flexibility for home access.

FAQs
What should I do if I am locked out after multiple authentication failures?
After 10 incorrect password attempts, the Aqara lock disables password input for 30 minutes. You can still unlock the door using Bluetooth or the Aqara Home app during this time. This feature protects your home from unauthorized access.
Can I unlock my Aqara smart lock remotely when I’m locked outside home?
Yes. As long as your lock is connected to your home network, you can use the Aqara Home app to unlock your door remotely. This is especially helpful if you forgot your keys or need to let someone in when you’re away.
What happens if the door is locked from inside and I’m locked outside apartment?
If the door is locked from the inside, an administrator fingerprint or password can unlock the door from outside using Aqara smart locks. Emergency keys won’t work in this case, so contacting household members is sometimes necessary.
