Very good unit. Peace of mind and works very well
A solid unit and improvement over the original lock. Interested in the battery pack as it can get through batteries. Whilst showing high % on my particular install the lock is a bit tight so the battery needs to be really good and full. After about 70% they are working but might not lock properly. This is due to my door and lock though being quite tight.Integrates well with Home Assistant and the main app is also very good.I like the peace of mind and the instant alerts through the app. If the lock is not used or door is open. Or if the lock doesn’t work.The keypad set up is really good too with the fingerprint scanning.

Secure and easy to install
The SwitchBot Smart Lock Pro is an absolute winner for anyone looking to upgrade their home security with smart technology. Installation was a breeze, and the sleek design blends perfectly with my door. The fingerprint scanner is lightning-fast, and the auto-lock feature gives me peace of mind knowing my home is always secure.I love the convenience of unlocking the door via the app, voice control (works with Alexa & Google Assistant), or even my Apple Watch.The battery life is impressive, and the backup keys are a nice touch. If you want a reliable, feature-packed smart lock without breaking the bank, this is the one.

A Powerful Smart Lock with Room for Improvement
The SwitchBot Pro Lock is a strong contender in the smart home market, offering extensive integration capabilities and advanced features. While it excels in functionality, there are some design aspects that could use refinement, particularly for those looking for a more discreet smart lock.Design and Build QualityThe SwitchBot Pro Lock is sleek but undeniably bulky. Its size causes it to stick out more than most other smart locks on the market, which may not appeal to those prioritizing minimalism or aesthetics. While the build quality feels robust and durable, the protruding design can look out of place on slimmer doors or in modern homes. Hopefully, future iterations will address this issue with a more compact and streamlined design.Despite the bulk, the lock remains easy to install and works with a wide range of door types, so its usability isn't compromised.Features and PerformanceThe lock’s feature set is impressive. Its integration with Home Assistant provides endless automation possibilities, from automatically locking the door when you leave to unlocking it based on proximity sensors. Combined with the UniFi Doorbell, the setup becomes a comprehensive security solution. For instance, you can view the doorbell feed, verify visitors, and unlock the door remotely—all from a single app or platform.The NFC card support is particularly convenient, especially for households with children or elderly family members who may not always have access to a smartphone. It’s a simple, practical alternative to traditional keys, though some users may feel more secure with biometric options.ConnectivityConnectivity is one of the SwitchBot Pro Lock’s strengths. It offers stable Bluetooth and Wi-Fi performance, ensuring reliable communication with Home Assistant and other smart devices. Even in automation-heavy environments, the lock responds quickly, making it a dependable addition to any smart home ecosystem.SecuritySecurity remains a top priority, and the SwitchBot Pro Lock delivers with advanced encryption and optional two-factor authentication. When paired with the UniFi Doorbell, the ability to visually confirm visitors before unlocking the door adds an extra layer of reassurance.DrawbacksThe primary drawback of the SwitchBot Pro Lock is its size. The bulky design can be visually distracting and might not suit all door styles. This is an area where improvement is necessary, and a slimmer, more compact version would make it much more appealing. Additionally, while NFC card functionality is a welcome feature, it may not feel as secure as biometric options for some users.Final ThoughtsThe SwitchBot Pro Lock is a powerful and feature-rich smart lock that integrates seamlessly with Home Assistant and the UniFi Doorbell, making it an excellent choice for those looking to enhance their smart home ecosystem. However, its bulky design may deter users who prefer a more subtle appearance. If you can overlook the size, the Pro Lock is a reliable and versatile addition to your smart home. Hopefully, future versions will address the design concerns while retaining its robust functionality.Rating: 4/5

Tech savvy DIYers ok to install and set up, anyone old or young can be taught to use it.
Literally changed our barrel of a eurolock with thumb turn key to a two sided regular key one, in order to fit this! But it was a game changer for my elderly mum. She now can use her fingerprint to get in the house and does not have to fiddle about trying to find a key to put in her lock (under her handle which is already shaded and therefore difficult to see!). You can add up to 100 users. The quality is good and it appears sturdy, I'm pretty DIY competent so I changed the barrel to make it work, if you have a thumb turn key, and you have to change the eurolock barrel watch youtube videos, you can buy a replacement for about £12 from B&Q. You do need to be tech savvy to set this up, my husband and & calibrated this for my mum, she would never have been able to do this alone. But we found it easy to fit, easy to use my elderly mum to use (which is amazing) and we've set it to lock 1 minute after she gets in, so great lock functionality. She can now never forget her key, and it won't matter if she forgets to lock the door...

Buggy device. Reddit also full of users with problems.
The media could not be loaded. Though this was not necessarily compatible with my type of door, it was relatively easy to DIY it a little to make it fit nicely still, by adding a bit of wood to attach the lock pro to, and replacing my cylinder with a removable knob one so that it could accept the adapters.Unfortunately on three occasions so far the lock seems to have gotten confused, and lost its calibration setup, causing it to fault and claim it is jammed. This prevented me on each time from being able to unlock my door without using the key. I'm engaging in support.I love the fingerprint reader, and the ability to use a code entry as well as NFC card too. Best of all, the key still functions perfectly from the outside in case of some failure. I've had it installed about a week now, and haven't experienced any issues getting into the house as long as I have my key handy for backup, or the lock pro has battery power so that you can use the emergency unlock feature even after fault.The materials and manufacturing feel well designed and machined. Installation looks complicated but in the end was not too difficult for someone with just a bit of DIY abilities.

Best smart lock to retrofit to most locks
I was really surprised that this smart lock was compatible with my door. I have a high security Assa Aboly front door with a thumb turn cylinder and the adapter fitted the thumb turn correctly. I love the digital keypad. Easy to install! High quality lock with manual override.
