The key handover problem
Homestays, service apartments and short-stay rentals across Bangalore — in Koramangala, Indiranagar, Whitefield and near the airport — share one daily headache: getting keys to guests who arrive at midnight, getting them back when guests leave, and making sure cleaners and maintenance staff can get in without a caretaker waiting around. Lost keys mean changing locks. Smart locks remove the physical key and replace it with codes, cards or phone keys that start and end automatically.
Access options compared
| Method | How guests use it | Best for |
|---|---|---|
| PIN code per booking | Code sent before arrival, valid only for the stay | Homestays and single rental units |
| RFID card | Card handed over or left in a key box | Service apartments with a front desk |
| App or Bluetooth key | Guest opens with a phone link | Tech-savvy guests, multi-unit operators |
| Fingerprint | Not practical for short stays | Owner and long-term staff only |
| Mechanical key | Emergency backup | Kept with the owner, never with guests |
Self check-in that works
- Generate a unique PIN for each booking, valid from check-in time to check-out time.
- Send it with the address and instructions shortly before arrival, not weeks ahead.
- Use a video doorbell or camera at the building entrance (never inside the unit) to confirm arrival.
- Keep a backup code and a phone number for guests who get locked out.
- Change or expire codes automatically after check-out.
Cleaners, maintenance and owners
Give housekeeping and maintenance staff their own codes or cards, limited to working hours, so the lock’s log shows who entered and when. This settles disputes about cleaning times and missing items, and lets you remove access the day someone stops working for you.
Linking to booking platforms
Some smart lock platforms connect to property management systems or channel managers, creating a code automatically when a booking is confirmed and deleting it after check-out. For a few units, generating codes manually in the lock app works fine. For a larger portfolio, automation saves hours each week and avoids codes being forgotten.
Power, batteries and connectivity
- Most smart locks run on batteries; set a reminder to check levels on every changeover.
- Choose locks with an emergency power point or mechanical key.
- Wi-Fi or a gateway is needed for remote code creation and live logs.
- Keep the gateway and router on a UPS so remote access survives power cuts.
Security and guest trust
- Never reuse codes between guests.
- Use locks from established brands with encrypted communication and firmware updates.
- Secure the owner’s app account with a strong password and two-factor login.
- Disclose any exterior cameras in the listing; never place cameras inside the unit.
- Keep the inside handle free to open without codes, for fire safety.
An example
An owner running six service apartments in one Whitefield building replaced brass keys with smart locks connected through a gateway on each floor. Each booking now generates a PIN that works from 1 pm on arrival day to 11 am on departure day, cleaners have time-limited codes, and the owner sees every entry in one app. Late-night arrivals no longer need a caretaker, and lost-key lock changes stopped completely.

Do smart locks need Wi-Fi?+
Not to open, but Wi-Fi or a gateway is needed to create codes remotely and see live logs.
Can I see when cleaners came?+
Yes. Each staff code shows in the entry log with time and date.
