VEVOR Mechanical Keyless Entry Door Lock, 2.0 Code Upgrade, 4-7 Digits Code, Double-Sided Push Button Combination Mechanical Keypad Door Knob, Auto Locking, for Indoor or Outdoor, Oil-Rubbed Bronze

2.0 Code Upgrade with Direct Programming Using Handle and Keypad

The mechanical keyless door lock features a 2.0 code upgrade that lets you change your entry code using the keypad. You can change the entire code without locking off the door or taking any parts apart to program them. Simple mechanical steps are used to upgrade the lock, which can be done from the outside with the current code. That means that you do not have to take the lock off and put it back on every time.

The 2.0 upgrade system makes it easy and quick to change the code when you need to improve security after guests visit or when a tenant moves out. The mechanical method of programming is reliable because it does not use any electrical parts that could break or require technical knowledge to use. Using the keypad and handle, all you have to do to set new codes is follow the programming procedure.

Mechanical Keyless Door Lock with 4-7 Digit Codes Allowing Any-Order Entry and X/Z Letter Support

For greater security, the keyless door lock supports codes 4 to 7 digits long. The system uses numbers along with the letters X and Z to offer more code possibilities than systems that use only numbers. For extra security, the any-order entry feature lets you enter code digits in any order, rather than requiring a specific order. With this jumbled entry, people who see you pressing buttons can not figure out your real code.

You can choose between shorter codes for ease of use and longer codes for better protection, depending on your needs. Adding the X and Z letters makes a huge difference in the number of possible code combos compared to systems that use only 10 digits. The feature lets you enter your 5-digit code at any time, so it could be part of a longer, random pattern that makes it hard for anyone to understand.

Battery-Free Mechanical Operation with No Wiring Required

The mechanical keyless door lock does not require batteries or electricity to operate; it works mechanically. Entering the right code retracts the latch, thanks to gears and springs inside the lock. With this setup, you do not have to worry about dead batteries locking you out at bad times. The mechanical process does not need any wiring or connection to your home’s electrical systems.

The mechanical design allows for true keyless entry without the problems with upkeep and dependability that come with electronic locks that need batteries. You never have to worry about replacing batteries or having electrical parts break down due to water or temperature changes. It continues to work even when the power goes out, which can happen with electronic locks that lack backup power and can fail or lose their settings.

Mechanical Keyless Door Lock with 4 Spindles for 1.4″-2.5″ Door Thickness and 2 Latch Sizes

The keyless door lock comes with 4 spindles that fit doors 35 to 65 mm thick (1.4 to 2.5 inches). With multiple spindle options, the lock will fit properly on most standard residential door thicknesses, with no gaps or binding while operating. The kit also comes with two different latch sizes, 2.3 inches (60 mm) and 2.7 inches (70 mm), so you can use them with doors of different levels.

With the four spindles, you can cover everything from thin interior doors to thick exterior security doors. For proper knob spacing and smooth operation, choose a spindle length that matches the thickness of your door. You do not have to replace the door frames because the two latch sizes fit different backset positions and strike plate positions. The lock’s type means it can be used to replace old locks without changing the door.

Double-Sided Code Control with Hold-Open Mode for Controlled Access

The double-sided code control on the mechanical keyless door lock allows entry from both the inside and the outside. You can require code entry on both sides, or set up a one-way free exit from the inside using the dual-sided feature. The lock has a hold-open mode that keeps the latch retracted, making it easy to get in and out during busy times. The mode is helpful when family members come and go a lot, like at parties or when moving.

By requiring codes on both sides during setup, the double-sided control prevents unauthorized entry or exit. With the hold-open mode, you do not have to enter codes over and over again when you are moving things through the door more than once. You manually switch to hold-open mode and then easily switch back to normal closing when you are ready.

Zinc-Alloy Body with Rust-Resistant Coating for Indoor/Outdoor Use

The zinc-alloy body of the keyless door lock is strong enough to survive daily use and weather conditions. The zinc-alloy material is stronger and lasts longer than plastic locks, and it offers good corrosion resistance. The oil-rubbed bronze finish on the lock makes it rust-resistant and protects it from rain, sun, and other outdoor elements.

The zinc-alloy design can withstand daily use without breaking or wearing out from repeated code entry and door openings. The rust-proof layer does not break down in humid places, along the coast, or in places that get a lot of rain and snow. The oil-rubbed bronze finish gives the door a nice, traditional look that complements a wide range of architectural styles and door colors.
