The Most Common Mistake I See in Airbnb Apartments

Self check-in has become the standard for Airbnb properties. The easiest solution is often to install a key lock box next to the entrance door so guests can collect the key whenever they arrive.

In Budapest’s historic apartment buildings with open-access corridors, another common solution is attaching a cheap combination padlock or key box to the hallway railing.

While these options are convenient for hosts, they are increasingly attractive targets for criminals.

Criminals Know Exactly Where to Look

As a locksmith, I receive more and more calls where the problem isn’t a damaged lock—it’s the compromised key storage.

Experienced thieves know that:

• many Airbnb apartments store their keys outside the entrance,
• cheap lock boxes and combination padlocks can often be forced open within seconds,
• once they have the original key, they can enter without leaving obvious signs of forced entry.

I’ve personally encountered cases where criminals simply pried open a lock box or cut through a padlock, removed the apartment keys, and occupied the property without permission. In other situations, valuable belongings disappeared before the owner even realized someone had gained access.

Since the apartment is entered using the original key, proving unauthorized entry becomes significantly more difficult than after a traditional break-in.

Not All Key Lock Boxes Offer the Same Level of Protection

If you decide to use a lock box, avoid purchasing the cheapest option available online.

Low-quality products often feature:

• thin cast metal construction,
• weak locking mechanisms,
• poor resistance against prying attacks,
• inadequate mounting hardware.

Even if you’ve invested in a high-security door and premium lock cylinder, leaving the key inside an easily defeated lock box undermines the entire security system.

If You Still Use a Lock Box, Follow These Recommendations

• Choose a professional-grade steel key lock box from a trusted manufacturer.
• Install it using heavy-duty anchors and security fixings.
• Avoid mounting it directly beside the apartment entrance whenever possible.
• Change the access code regularly.
• Never reuse the same code for every guest.
• Inspect the box frequently for signs of tampering.

These precautions can improve security, but they cannot eliminate the risk entirely.

Smart Locks Are Often the Better Long-Term Solution

For Airbnb hosts, I increasingly recommend replacing traditional key management with a modern smart lock.

A quality smart lock offers several advantages:

• No physical key is left outside the property.
• Each guest receives a unique, time-limited access code.
• Access permissions can be revoked instantly.
• No more key exchanges or lock boxes.
• Many systems can be managed remotely from anywhere.

By removing the physical key altogether, one of the most common attack methods simply disappears.

High-Security Lock Cylinders Still Matter

I’ve previously written about the importance of restricted key cylinders for Airbnb apartments, and I continue to recommend them.

However, even the best security cylinder cannot protect your property if the key is left inside an easily accessible lock box.

Effective Airbnb security requires both a secure locking system and a secure key management strategy.

Final Thoughts

Based on my experience working with Airbnb properties throughout Budapest, one of today’s biggest security weaknesses isn’t the door or the lock—it’s how hosts store their keys.

Cheap key lock boxes installed beside apartment doors and lightweight combination padlocks attached to corridor railings have become increasingly common targets for criminals.

If you absolutely must use a lock box, invest in a high-quality model and ensure it is professionally installed using strong fixings.

If you’re looking for the safest and most convenient long-term solution, a professionally installed smart lock is usually the best choice.
