The Atomberg Azhero Smart Lock Installation Guide: Door Requirements, Size & Free Installation Details
This smart lock can be installed on wooden doors with a minimum thickness of 28 mm. The installation is done by the Atomberg team for free in 31 cities that Atomberg covers. For other cities, it can easily be done by a carpenter as the instructions are straightforward.
Smart locks are generally large, almost 1 foot in height. If you already have a lock in that space, you’ll likely need to remove it. Depending on the dimensions of the existing lock, you may need to get the door fixed for marks after the installation is complete. Factor all of these in during your installation process.
Atomberg Smart Lock Battery Life & Emergency Power Backup Explained
For this lock, you will need four batteries for it to function. The batteries last approximately 9–12 months before needing replacement. If the battery is drained, you can use your mechanical keys for opening the door or charge the lock using a micro USB cable from the outside to open using any of the access modes.
Atomberg Smart Lock Connectivity: Bluetooth vs Wi-Fi Performance Comparison
Atomberg Azhero is a Bluetooth smart lock, not Wi-Fi, so you don’t need to worry about constantly keeping your Wi-Fi on and your Wi-Fi not working, and your battery draining out faster, which is very typical with Wi-Fi-based smart locks.
How Secure Is the Atomberg Smart Lock? Security Features, Encryption & Data Privacy
The Atomberg Azhero Smart Lock is not just about convenience, it’s also about security. With two stainless steel bolts, it offers double the security of traditional locks. For those who need even more security, there’s a higher variant with five bolts. The door can be opened by any of the five keyless modes of access or using a mechanical key, providing you with peace of mind.
Atomberg Smart Lock Unlocking Methods: All Access Options Explained
- Fingerprint: Quick and secure, supports up to 100 fingerprints.
- PIN Code: Includes permanent, periodic, and guest PINs for flexible access.
- NFC Card: Provides office-like keycard entry; includes two cards.
- Remote OTP: Generate a 10-minute-valid OTP from anywhere.

A unique feature in this lock is the snoop protection. So when somebody is looking over your shoulder when you are keying in your PIN code, you can add random numbers before or after your PIN before or after your actual PIN so that the snoop does not figure out the actual PIN. The smart lock can decipher your actual PIN from this random string of numbers.
If you’re concerned about data privacy and security, then be assured that all of your data is encrypted end-to-end and stored in India, not overseas. Your data is encrypted end-to-end and stored in India, ensuring that even Atomberg employees cannot access it.
Now, whether you have guests coming over when you are not at home or you want to give one-time access to your house help for a small period, this Atomberg smart lock has you covered. There are five keyless modes of access, plus two mechanical keys that Atomberg provides with the lock, just in case.
Atomberg Smart Lock Fingerprint Access: Speed, Accuracy & User Limits
Fingerprint is the easiest mode of access. You can unlock your door with just the touch of a finger. This mode is quick and secure and is perfect for family members, including kids, who run in and out a zillion times.
The blue light indicates the lock is reading the fingerprint, the red light indicates an incorrect fingerprint, and the green light indicates a go. You can configure up to 100 fingerprints using the Atomberg App.
Atomberg Smart Lock PIN Access: Permanent, Periodic & Guest PIN Explained
Three types of PINs can be generated using the Atomberg Smart Lock. Periodic PINs are ideal for maids or cooks who come at a specific time of day, and you don’t want to give permanent access to them via fingerprints and access cards. You can provide them with access only for a specific time via PIN codes.
Permanent pins are ideal for residing members of the family. Guest pins are suitable for guests visiting for a short period, so they can conveniently access the door even when you are not available at home. We can set up to 100 PIN codes using the Atomberg app.
Atomberg Smart Lock Remote OTP Access: Unlock from Anywhere Without Wi-Fi
If you are not at home and you have a visitor that you want to let in, there is no need to worry about the logistics of leaving a key behind for them anymore.
You can always generate a new OTP from anywhere in the world and send it to them via SMS or WhatsApp. And yes, this is even possible without Wi-Fi on the smart lock. This OTP is valid only for 10 minutes.
Atomberg Smart Lock App Control: Remote Unlocking & Access Management
If you’re too busy to pause the TV to open the door, the Atomberg Home App has you covered. With this app, you can easily open the smart lock, ensuring you always know who is at the door before opening it. This user-friendly feature is designed to make your life easier and more convenient.
NFC Access Card: Office-Style Keycard Entry Experience
Now you can also experience an office or hotel-like entry when working from home using the access card option. It’s also ideal to share with maids or cooks if they are uncomfortable using a PIN code type access. Atomberg gives two access cards by default. It provides permanent access to the cardholder, so make sure to distribute it carefully.
Smart Lock Mechanical Key Backup: Emergency Access & Reliability
And lastly, if you are worried about the smart lock not working or batteries running out, you can always use a mechanical backup key. You can save it safely at your neighbour’s or your friend’s house to have access to it when you need it.
If a lack of battery charge is the reason for not having access, then, like I mentioned before, you can always charge it with a battery bank to gain access to your door. In addition to setting up access or using it to open the door remotely, you can also see a history of access using the smart lock on the app.
The app by itself is very convenient to use, with free installation in select cities and a two-year warranty. This Atomberg smart lock is a reliable, secure and convenient way to secure your home.
