1. BOTHSTAR Keypad Door Knob with Key,Keyless Entry Door Lock, Code Locks Door Knob, Auto Lock,50 User Code,Easy to Install,for Home,Office,Bedroom,Garage,No Deadbolt

When I first came across the BOTHSTAR Keypad Door Knob with Key, I was immediately impressed by its combination of advanced security features and user-friendly design. As someone who values both safety and convenience, this keyless entry door lock seemed like a perfect solution for multiple settings such as my home, office, bedroom, or even garage. The fact that it includes a traditional key option alongside the keypad is a thoughtful touch, giving me peace of mind in case of any electronic issues.

One of the standout features for me is the double-sided keypad with dual cylinders. This means I can set up to 50 unique user codes on each side independently, or synchronize them for ease of use. This level of customization is ideal if multiple people need access at different times or if I want to restrict entry in a controlled manner. The backlit keypad is another practical aspect that ensures I can easily enter my code even in low light or at night without fumbling around.

The smart-locking capabilities really elevate this product’s functionality. Being able to switch between auto-lock and manual lock modes on both sides adds a layer of versatility that fits various security needs. For example, if I want the door to lock automatically when it closes for added protection, I can do that. Alternatively, for a situation where I might want to keep the door unlocked temporarily, the manual mode is there. This is especially useful for child safety or in busy office environments where quick, secure entry is critical.

Security and convenience are clearly well balanced here. The anti-prying technology reassures me that the lock is resistant to forced entry attempts, while the option to enable silent mode to deactivate the buzzer is a subtle but significant feature—no loud noises alerting anyone nearby when I enter my code. Another aspect I appreciate is the power system running on 4 AAA batteries with a low power consumption design that lasts over a year, coupled with a low battery alarm to warn me before it dies. Plus, the ability to temporarily power the lock with a 5V USB-C cable in emergencies is a smart fail-safe. The fact that it generates temporary dynamic passwords without needing Wi-Fi means I avoid the risks of hacking or connectivity issues altogether.

Installation and durability are other areas where this lock shines. It fits universally on metal or wooden doors with thicknesses from 1-3/8″ to 2-3/4″, and comes with adjustable latches to accommodate different door setups. Made from high-quality zinc alloy with an electroplated finish, it feels solid and built to last. I also find it reassuring that the lock is suitable for exterior applications like garden gates or fences, expanding its usability beyond just indoor doors.

Lastly, the ALL WEATHER rating and trusted warranty make this an even more attractive option. With an IPX6 waterproof rating, I don’t have to worry about rain or moisture damaging the lock if installed outdoors. It can handle extreme temperatures ranging from -22°F to +176°F, which means it remains reliable no matter the climate. The manufacturer’s 1-year warranty, lifetime after-sales service, and 24/7 online technical support add an extra layer of confidence for me as a buyer.

This isn’t just any lock—it’s a Gen2 mechanical keyless model, which means it operates entirely mechanically without relying on batteries or electricity. For me, that’s a huge plus because it removes the worry of the lock failing due to dead batteries, especially in outdoor settings like gardens or garages where power sources might not be readily available. The ease of installation and operation stood out right away, and the fact that changing the password is now much simpler makes it user-friendly even for those who aren’t tech-savvy. One of the features I find particularly impressive is the universal compatibility of this lock. It comes with multiple sets of screws and spindles in various sizes, allowing it to fit a wide range of door thicknesses from 1.4″ to 2.5″. This versatility means I could easily use it on my garden gate, garage door, or even a metal fence door without worrying about compatibility. The installation process is straightforward, though it requires drilling an additional hole and ensuring the front and rear panels align perfectly. This flexibility makes it a great choice for anyone looking to upgrade their outdoor security without replacing their entire door or frame. The auto-lock and normal open modes add a thoughtful touch to this lock’s functionality. For me, the auto-lock feature is essential because it secures the door automatically once it closes, which eliminates the risk of accidentally leaving it unlocked. On the other hand, the normal open mode is a clever upgrade that’s perfect for situations where frequent access is needed—like when kids or elderly family members need to come and go easily. This mode essentially converts the lock into a simple handle, making daily use convenient without compromising security when needed. Durability is always a concern with outdoor locks, but the VEVOR lock’s zinc alloy construction combined with a corrosion-resistant electroplated coating gives me confidence it can withstand harsh weather conditions. Whether it’s freezing winters, hot summers, or heavy rain, this lock is built to resist water and rust, ensuring long-term reliability.

Another aspect I appreciated is how user-friendly the lock replacement and handle adjustments are. The handles can be switched for left or right door orientations, providing flexibility for different door setups. The latch bolt’s push-pull structure simplifies direct replacements, which is a time-saver if you’re upgrading from a previous lock. Plus, the large padding plate means I didn’t have to create a big hole in my door, preserving the aesthetics of my gate while adding strong security.

What really adds to the convenience is the password synchronization feature. Knowing that any code changes on one side automatically update the other side saves me the hassle of managing two separate codes.

The low battery beep and ultra-low power consumption give me peace of mind that the lock won’t suddenly fail, and the inclusion of a Type-C USB charging port for emergencies is a thoughtful backup option I really appreciate.

Buying Guide for Double Sided Keypad Lock Understanding What a Double Sided Keypad Lock Is When I first looked into securing my home, I discovered that a double sided keypad lock offers keyless entry from both sides of a door. This means I can enter a code to unlock the door whether I am inside or outside, which adds convenience and security. Assessing Your Security Needs I had to think about where I wanted to install the lock and how much security I needed. For example, a front door facing the street requires a more robust lock with advanced features compared to an interior door. Knowing this helped me decide on the type of keypad lock that would best suit my situation. Choosing the Right Lock Type Double sided keypad locks come in different styles, such as deadbolt or lever handle designs. I evaluated which style matched my door’s setup and my personal preference. Deadbolts typically offer higher security, while lever handles might be easier for frequent use. Considering Power Options Most keypad locks run on batteries, so I checked how long the battery life lasts and whether the lock has low-battery alerts. I also looked for models with backup power options or mechanical keys to avoid getting locked out if batteries die. Evaluating Security Features I looked for features like anti-tamper alarms, automatic locking, and the ability to set multiple user codes. These features gave me peace of mind knowing that unauthorized access attempts would be detected or prevented. Installation and Compatibility Installing the lock myself was important to me, so I chose a model that came with clear instructions and fit my door’s thickness and type. I also checked whether I needed any additional tools or professional help. Ease of Use and User Interface Since I share my home with family members, I wanted a keypad that was easy to use and had a clear display. Some locks offer touchscreen keypads or illuminated buttons, which make entering codes easier, especially at night. Budget Considerations I set a budget before shopping and compared locks within that range. While some models have extra features that cost more, I focused on what I truly needed to avoid overspending. Warranty and Customer Support Finally, I reviewed the warranty terms and customer support availability. Knowing I could get assistance or a replacement if something went wrong gave me confidence in my purchase. Author Profile Parker Leslie Hi, I'm Parker Leslie.
