How to Hide and Secure a Spare Key — Without the Risk
Hiding a spare key outside your home is a security risk. Here are safer alternatives that provide emergency access without the vulnerability.
· 4 min read · Residential
Most homeowners keep a spare key somewhere outside their home — under the mat, in a fake rock, above the door frame, or with a neighbor. The problem is that burglars know all of these locations and check them routinely in residential neighborhoods.
If you need emergency access capability, here are the better alternatives.
Why Traditional Spare Key Hiding Fails
The classic spare key locations are widely known because they've been widely used for decades: - Under the mat - In a flower pot - Above the door frame - Under a decorative rock - In the mailbox
A motivated burglar will check all of these in under 2 minutes. Miami's active property crime environment means this is a real risk, not a theoretical one.
Better Alternative 1: Combination Lockbox
A quality lockbox mounted out of direct sightlines — not directly at the front door — provides combination-protected spare key access. Use a lockbox with: - A steel body (not plastic) - A combination that is not obvious (not your address, birth year, or 1234) - A concealed location (rear entry, side gate, or buried in landscaping)
Change the combination periodically, especially after giving it to contractors or service providers.
Better Alternative 2: Smart Lock or Keypad
This eliminates the need for a spare key entirely. A keypad lock lets you enter a code if you're locked out — no key required. You can share the code with trusted family members without making physical copies, and change it any time without rekeying.
Smart locks with app control go further: you can unlock your door remotely for a family member or let yourself in if you forget your code.
Better Alternative 3: Trusted Neighbor
A neighbor who holds your spare key is the most secure "hidden key" solution — the key is indoors, not accessible to random passersby, and your neighbor can verify your identity before handing it over. The limitation is availability: neighbors travel, have work schedules, and may not always be reachable.
Better Alternative 4: Property Manager or Landlord
For renters, your property manager typically maintains a master key. This is a built-in spare key resource — check whether 24-hour emergency access is available.
What to Do If You're Locked Out Without a Spare
