Key Takeaways
- The Good: Installs over existing locks without drilling, supports the universal Matter protocol, and offers diverse unlocking methods including voice control.
- The Requirements: Full functionality, such as fingerprint unlocking, requires the optional external keypad or additional door sensors.
- Best For: Renters or homeowners who want smart security without replacing their entire door mechanism or damaging the frame.
Upgrading your home security usually involves messy drills, complex wiring, and completely replacing your door hardware. Xiaomi is changing that narrative with the release of the Self-Install Smart Lock.
This retrofit device is designed to bring modern intelligence to your existing door setup. Instead of removing your current lock, this unit mounts directly over standard cylinders, making it an ideal solution if you cannot modify your property permanently.

It supports eight different lock types, including Euro profile, UK mortise, and ASSA 2000 systems. As long as your key is up to 5mm thick, this device integrates seamlessly with your current hardware.

Universal Control with Matter Support
One of the standout features of this device is its support for the Matter smart home protocol. In simple terms, this means the lock can “talk” to smart devices from different brands without compatibility headaches.
Whether you use Alexa, Google Assistant, or Apple Home, the lock integrates smoothly into your existing ecosystem. You can issue voice commands to lock the door, though some platforms may ask for extra authentication steps to ensure it is really you speaking.
For connectivity, the device utilizes both Wi-Fi and Bluetooth. This enables real-time monitoring directly from the Xiaomi Home app, allowing you to check if the door is locked or view access logs from anywhere in the world.
Multiple Ways to Unlock
While it retains the ability to use your traditional key, the lock opens up a world of digital access. You can unlock your door using permanent passwords for family or temporary ones for guests.
For a faster experience, the system supports fingerprint recognition. This feature utilizes an optional IP65-rated keypad equipped with a semiconductor sensor, boasting a high 99.3 percent identification rate.
Security is reinforced by Xiaomi’s proprietary MJA1 chipset and EN18031 European cybersecurity certification. The app also keeps you informed with critical alerts, such as notifications for “door open” reminders, anti-tamper warnings, or if someone makes multiple failed attempts to enter.
6-Month Battery Life
Smart locks are only useful if they have power, and Xiaomi has addressed this with efficiency. The main unit is powered by a 2450mAh lithium battery.
Under normal usage conditions, this battery is rated to last approximately six months. This longevity minimizes the hassle of frequent recharging, ensuring your home remains distinctively secure for half a year on a single charge.
Pricing and Availability
The product has been spotted on Xiaomi’s global website as of October 2025 and is currently available in select markets.
In Japan, the device is listed for ¥12,980 (approx. $82), while in the UAE, it retails for AED 359 (approx. $98). Support pages have also appeared for the UK and various EU regions, suggesting a broader rollout is imminent.
