Features of the GUDLAIF Smart Door Lock

The GUDLAIF Smart Door Lock has a lot of features that make it stand out from other smart locks on the market. Here are some of the main ones:

  • 5-in-1 Ways to Unlock: You can choose from five different methods to unlock the door: fingerprint, app control, passcode, fob, or key. The fingerprint sensor can store up to 100 fingerprints and has a recognition speed of less than 0.5 seconds. The app control option allows you to lock or unlock the door remotely using the TTlock app on your smartphone through a gateway (sold separately). The passcode option supports anti-peeping virtual password, which means you can add any random digits before and after your actual password to prevent others from guessing it. The fob option lets you use a small device that you can attach to your keychain or wallet to unlock the door. The key option is a backup option in case the battery runs out or the other methods fail.
  • WiFi and App Control: The GUDLAIF Smart Door Lock can be connected to WiFi or Alexa through a gateway (sold separately) and controlled via the TTlock app on your smartphone. The app allows you to monitor the lock status, view the unlocking records, share temporary or permanent access codes or e-keys with family, friends, or guests, set auto-lock time, and receive low battery alerts. The app is free to use and compatible with iOS and Android devices.
  • High Quality Security Chip: The GUDLAIF Smart Door Lock has a safety chip that ensures the stability and security of the lock. The chip has a self-learning algorithm that can improve the recognition rate and accuracy of the fingerprint and passcode. The chip also has a memory function that can store the unlocking records and settings even if the power is off.
  • Tempered Glass Touchpad: The GUDLAIF Smart Door Lock has a touchpad made of tempered glass that is resistant to scratches, water, and dust. The touchpad has a backlight that makes it easy to see and operate in the dark. The touchpad also has a voice prompt function that guides you through the operation and gives you feedback.
  • Durable Aluminum Alloy Lock Body: The GUDLAIF Smart Door Lock has a lock body made of aluminum alloy that is sturdy and durable. The lock body has a built-in deadbolt that can withstand up to 3000 pounds of force. The lock body also has a reversible handle that can be installed on both left and right doors.
  • Micro-USB Port for Emergency Power Supply: The GUDLAIF Smart Door Lock is powered by four AA batteries that can last for about one year or 10,000 times of unlocking. However, in case the battery runs out or there is any other fault, you can use a micro-USB cable to connect the lock to a power bank or a phone charger and unlock the door. You can also use the mechanical key as a backup option.
  • Satisfaction Service: The GUDLAIF Smart Door Lock comes with a 30-day money back guarantee, a one-year product warranty, and a lifetime customer support. The product also has a guiding video for operation and installation that can help you set up and use the lock easily. If you have any questions or issues, you can contact the customer service online and get a reply within 24 hours.
