🔎 Why Every STR Needs a Lockbox (Even With a Smart Lock)

Technology fails. Batteries die. Guests lock themselves out.
A physical lockbox ensures:

✔ Backup entry for guests
✔ Cleaner + maintenance access
✔ Emergency access if your smart lock glitches
✔ No late-night “We can’t get in” messages
✔ Peace of mind for remote hosts

A $20–$60 lockbox can prevent expensive emergencies and bad reviews.

📈 What Guests Prefer

A recent STR Community poll found that over 80% of guests prefer self-check-in because it:

• Reduces stress from travel delays

• Allows late-night arrivals

• Eliminates awkward check-in coordination

• Feels more professional and streamlined

A good lockbox supports that experience.

🧠 How to Choose the Right Lockbox

Consider these factors:

1. Climate

Cold weather can freeze dials. Humid markets need weather covers. Choose accordingly.

2. Security Level

Dense urban markets = choose hardened steel + mountable designs.

3. Price vs. Reliability

Cheap is fine — unless you’re hosting high volume. Then durability matters.

4. Purpose

• Main guest key

• Backup key

• Cleaner/vendor access

• Equipment or storage access

Different needs require different designs.
