Smart Security with Emergency Access and Anti-Peeping Protection Door Lock
When it comes to home security, convenience matters—but so does having a reliable backup when something goes wrong.
The Signstek ST-668 Touchscreen Keypad Door Lock with Handle combines keyless entry, emergency mechanical access, anti-peep password protection, and a reversible door handle in one modern design. Whether you're upgrading your front door, guest room, rental property, or office, the ST-668 is designed to make everyday entry easier while giving you extra peace of mind.
No More Worrying About Getting Locked Out
One of the biggest concerns with an electronic door lock is what happens if you forget your code or need an emergency way to get inside.
The ST-668 includes a hidden mechanical keyhole behind the keypad handle. If you need emergency access, simply:
- Remove the keypad handle with the included wrench.
- Locate the hidden mechanical keyhole.
- Insert the mechanical key.
- Turn the key clockwise.
- The electronic door lock will open.
This backup mechanical access gives you another way to enter when you need it—without having to rely entirely on the keypad.
Tip: Keep the mechanical key somewhere safe and accessible outside the locked area, such as with a trusted family member.
Enter Your Password Without Worrying About Peeping
Entering a door code in public can sometimes feel uncomfortable, especially when someone is standing nearby.
The ST-668 features anti-peep password technology that allows you to enter random numbers before or after your actual password.
For example, if your correct password is:
123456
You can enter:
789123456321
As long as your correct password is included in the sequence, the lock can recognize it.
This means you don't have to worry as much about someone watching your fingers while you're entering your password.
It's a small feature that can make a big difference in everyday privacy and security.
A Reversible Handle for Left- or Right-Handed Doors
Not every door has the same configuration. That's why the ST-668 comes with an interchangeable door handle.
The handle can be adjusted for left-handed or right-handed doors, making the lock more flexible for different door setups.
Whether you're replacing an existing lock or upgrading a door in your home, the reversible design makes it easier to match the lock to your door.
Modern Security Meets a Clean, Stylish Design
Security doesn't have to look industrial.
The ST-668 features a touchscreen keypad and upscale appearance, making it a natural fit for modern homes, apartments, offices, and other spaces.
With no traditional keypad buttons to press, the touchscreen gives the lock a clean and contemporary look while keeping everyday entry simple.
