Smart locks
Guests let themselves in. No key handovers.
Rentalls connects to Nuki, TTLock and Igloohome locks. When a guest completes online check-in, the system generates a unique PIN valid exactly from check-in to check-out and sends it automatically.
Nothing is charged during the 14-day trial. Cancel anytime.
The PIN is generated once the guest completes online check-in
Conditions
Only guests who meet your conditions get the code
You decide when the PIN is released. Until the guest pays the deposit, uploads documents or completes check-in for all guests, the code stays hidden. For VIP guests you can release it instantly with one click.
- Code release gated by paid deposit or city tax
- Optional manual document approval by the host
- Code can be shown only after all guests check in
- VIP Unlock — instant access without waiting for conditions

Validity
The PIN works exactly from check-in to check-out
No codes that work forever. Every PIN has a time window based on the reservation — and when a guest buys an earlier arrival or later departure, the validity adjusts automatically. You set your own buffer before arrival and after departure.
- Validity window computed from reservation dates and times
- Early check-in and late check-out upsells extend validity automatically
- Optional ±1 or ±2 hour buffer before check-in and after check-out
When reservation dates change, the code regenerates automatically
Delivery
The code reaches the guest by itself — email, SMS and app
Put a shortcode into your automated message template and Rentalls replaces it with the real PIN when sending. The guest finds the same code in the guest app — hidden until they complete check-in.
- Code shortcode in email and SMS templates
- Sent automatically after check-in completion
- Code in the guest app along with arrival instructions
- Optionally reveal the code only from arrival time
