How to Avoid Getting Locked Out Again: Expert Prevention Tips
It always happens at the worst possible moment—you’re running late, your arms are full, and you reach for your keys… but they’re nowhere to be found. Whether it’s your house, car, or office, getting locked out is frustrating, stressful, and in some cases, expensive.
The good news? It’s entirely preventable.
This guide is packed with simple, expert-approved strategies to help you avoid lockouts in the future. From smart habits to tech upgrades, you’ll walk away with a plan to never face the panic of being locked out again.
1. Create a Key Routine You Can Stick To
Lockouts often happen when you're distracted or rushing. The best way to avoid them? Build a key habit. Choose a dedicated pocket, pouch, or hook for your keys and use it every single time.
Train yourself to do a mental (or physical) key check before leaving any location. Just like checking your phone or wallet, your keys should become part of your “leave-the-house” ritual.
2. Make Spare Keys—But Store Them Smartly
Yes, we’re saying it: spare keys save lives. But leaving one under your doormat or flowerpot? That's an open invitation for trouble.
Instead:
- Give a copy to a trusted friend, neighbor, or family member.
- Use a secure lockbox with a code—especially helpful for Airbnb hosts or family members coming and going.
- Consider a hidden key compartment disguised as a rock or utility box—but only in areas with low foot traffic and added security measures.

3. Duplicate Digital Access with Smart Locks
Tired of carrying keys altogether? Smart locks are a great upgrade.
These devices allow you to:
- Unlock with your phone, fingerprint, or keypad code
- Share temporary access with others (great for guests or maintenance)
- Receive alerts when someone unlocks your door
We cover everything in How to Upgrade to a Smart Lock Without Changing Your Door, so you don’t have to remodel your entire entry to go keyless.
4. Use Key Finders or Bluetooth Trackers
For chronic key-losers, a Bluetooth tracker like Tile or Apple AirTag can be a game-changer.
These tiny devices attach to your keyring and connect to an app, so you can quickly find your keys before locking yourself out—or at least know where they were last seen.
5. Install a Backup Entry Option
If you live in a house, consider a garage keypad, side door, or window sensor alert as a second line of defense against being completely locked out.
For apartment dwellers, talk to your landlord about entry policies and lock change protocols. You may be allowed to keep a spare key with management or a neighbor.
6. Always Check Before You Close
This may sound too simple to be effective—but it works. Train yourself to check for your keys before you close the door or trunk.
That 3-second pause could save you 3 hours of frustration—and a locksmith fee.
We’ve seen this issue a lot in car lockouts. Our post on How to Prevent Your Car Keys from Getting Locked Inside Again shares car-specific tips to avoid this headache.
7. Rekey or Replace if You’re Using Worn-Out Keys
Old, bent, or cracked keys are more likely to snap in the lock or fail altogether. If your key feels rough when turning or only works at a certain angle—it’s time to replace it.
A locksmith can rekey your lock to a fresh, duplicate key or cut a new one based on the original design. Not sure whether to rekey or replace? We’ve broken it down in Rekey vs Replace Locks: Which Is Better for New Homeowners?.
8. Don’t Rely on One Key Alone
Many people keep a single key on their keychain. That’s risky.
Instead, carry a second copy in a separate bag or wallet, or store one at your workplace, gym locker, or inside your car (locked in a coded box, not the glove compartment).
It’s your insurance plan against one forgotten moment.
9. Program Emergency Contacts and Locksmith Info
Even with the best habits, things happen.
Save the number of a trusted local locksmith in your phone now—don’t wait until you're panicking outside your door. Also, consider bookmarking our guide on How to Find a Licensed and Trustworthy Locksmith Near You.
You’ll thank yourself later.
10. Teach Your Household the Same Habits
Whether you live with family, roommates, or kids, everyone should know the game plan.
Where is the spare key?
Who has backup access?
What’s the smart lock code?
What should they do if locked out?
Consistency among household members can prevent miscommunications—and unnecessary emergencies.
