Bravex Mechanical Keypad Deadbolt Key Specs

Access Methods: Passcode, key

You can enter a custom code or use a physical key to unlock the door. This dual approach ensures you are never locked out if the keypad fails or batteries die, which is common in electronic smart locks. It offers a reliable fallback option for users who prioritize consistent access over remote app control features found in modern video doorbell ecosystems.

100% Mechanical

The lock operates entirely without electricity or batteries. You do not need to worry about power failures or low battery warnings interrupting your entry. This makes it a practical choice for renters or homeowners who want security without the maintenance of charging devices, unlike smart locks that require Wi-Fi or battery replacements for basic functionality.

Stainless Steel 304 deadbolt lock

The deadbolt is constructed from 304-grade stainless steel, a material known for high corrosion resistance and strength. This construction makes the lock very difficult to pry open compared to softer metals or plastic components found in cheaper alternatives. It provides a durable physical barrier that withstands weather exposure better than standard zinc alloy locks often used in budget smart hardware.

maximum borehole diameter 2-1/8"

This specification indicates the size of the circular hole required in your door for installation. A 2-1/8 inch diameter is the standard size for most residential doors in the US. You can verify your existing door preparation easily. If your door has a different hole size, you may need to drill new holes, which is not required if you are replacing a standard lock.

door thickness of 1.38-1.96inch

The lock fits doors with a thickness ranging from 1.38 to 1.96 inches. This covers the vast majority of standard interior and exterior wooden or metal doors. You should measure your door edge to ensure it falls within this range before purchasing. If your door is too thin or too thick, the internal mechanisms may not align correctly for proper locking.

Design and Build Quality

According to the listing, the Bravex Mechanical Keypad Deadbolt is constructed from 304 stainless steel. This material choice suggests a focus on durability and resistance to corrosion, which is practical for exterior doors exposed to weather. The finish is described as a Deadbolt with a Round Knob. This aesthetic is traditional and likely blends well with standard residential hardware styles rather than modern minimalist designs. The unit does not feature automatic locking, which simplifies the mechanical operation but requires you to engage the bolt manually after entering the code or using the key.

The physical dimensions are 6.1 inches in width, 4.1 inches in height, and 6.4 inches in length. It weighs one pound. These measurements indicate a standard-sized deadbolt that fits typical door preparations. The listing specifies compatibility with doors having a maximum borehole diameter of 2-1/8 inches. It also supports door thicknesses ranging from 1.38 to 1.96 inches. This range covers most standard interior and exterior wooden or metal doors in US homes. The lock is designed for both left and right-handed doors, as well as inward and outward opening configurations, providing flexibility during installation.

Controls consist of a mechanical keypad and a physical key override. The keypad allows for combinations of four to eight digits, with no repeated numbers. A notable feature is that the code can be entered in any order, offering convenience for users who may struggle with specific sequences. The 100% mechanical design means there are no batteries to replace, eliminating the risk of power failure. This makes it a reliable choice for users seeking a low-maintenance entry solution without electronic components.

Setup And Everyday Operation

Installation requires a standard door preparation. The lock fits doors with a borehole diameter of up to 2-1/8 inches. It accommodates door thicknesses between 1.38 and 1.96 inches. You can install this unit on both left and right handed doors. It works for inward and outward opening configurations. The mechanical nature means you do not need to wire any electronics or wait for a battery to charge. This eliminates the risk of a low battery leaving you locked out.

Setting the code is straightforward. You can choose a combination of four to eight digits. The listing notes that there should be no repeating digits in your chosen code. Once set, the order in which you enter the digits does not matter. This flexibility allows you to type the code in any sequence to gain entry.

Daily use is entirely manual. The lock does not auto-lock. You must turn the handle or lever to engage the bolt after closing the door. This feature suits those who prefer physical confirmation of their door status. It also means you do not need to re-enter your passcode every time you secure the door. If you prefer automatic locking, this mechanism may not fit your routine. However, the lack of moving electronic parts simplifies maintenance. You simply enter your code or use the physical key. The stainless steel construction provides a sturdy feel during these daily interactions.

Before You Buy This Lock

You should verify your door dimensions carefully before purchasing. The Bravex lock requires a borehole diameter of up to 2-1/8 inches. Your door thickness must fall between 1.38 and 1.96 inches. This unit works with both left and right handed doors, and supports inward or outward opening configurations. Since it is 100% mechanical, you will need to manually lock the deadbolt after entering. This means it does not auto-lock, which may require a change in habit. You must keep your physical key secure as a backup, even though you rarely need it. Maintenance is minimal, but you should clean the stainless steel surface periodically to prevent buildup. This lock fits well alongside video doorbells for a complete entry system. It offers a reliable, battery-free option for users who prefer simplicity over automation. Check your existing strike plate to ensure compatibility with the new deadbolt throw.

Check before you buy

• Verify door borehole diameter is under 2-1/8 inches.
• Confirm door thickness is between 1.38 and 1.96 inches.
• Ensure your door is left or right handed and inward or outward opening.
• Check that your existing strike plate matches the new deadbolt specifications.
