The guest arrives at 11 PM, you're 200 km away. With a key — problem. With a smart lock — "Your code is 4729, enter whenever you arrive." Review: 5 stars.
Why a smart lock
Flexible check-in is the second most common reason for a 5-star review (right after cleanliness). Guests don't want to wait for you in the car park at 2 PM. They want to arrive, open the door, and walk in.
3 options that work
### Key box — from €15
The simplest solution. A metal box with a combination, mounted near the entrance. Change the code between guests. No batteries, no WiFi, no complications.
### Code lock — from €80
Replaces the door cylinder. The guest enters a 4-6 digit code. Change it between guests. Batteries last 6-12 months. No internet needed.
### WiFi/Bluetooth smart lock — from €150
The most advanced option. Generates one-time codes, sends notifications when the door opens, controllable from your phone. Integrates with Airbnb for automatic code delivery.
What to watch out for
- Batteries — check monthly, keep spares - Backup key — always have a physical key as plan B, hide it in a safe spot - Guest instructions — write clear instructions WITH PICTURES, not just text - Security — change the code/password after EVERY guest
Total cost
Key box: €15-30 one-time. Code lock: €80-200 + batteries once a year. WiFi smart lock: €150-350 + batteries. No monthly subscriptions for basic models.
Comparison: one missed check-in due to a delayed flight can cost you a bad review and €500+ in lost future bookings. A smart lock pays for itself after the first such case.
Practical tips from experience
- Send the code 2 hours before check-in, not a day early (less chance of sharing) - Test the lock yourself at least 5 times before the first guest - Record a short video tutorial (30 seconds) and send via WhatsApp - If you have old wooden doors — check compatibility before buying
