    Questions and answers

    What is the difference between the HIDALIFE Smart Door Knob Lock and the HL668?
    The Smart Door Knob Lock is a full knob replacement that fits standard door prep and suits bedrooms, offices and rentals. The HL668 is a deadbolt with a keypad and app control, aimed at front doors where a heavier lock and auto-lock matter more.
    Does the HIDALIFE HL668 work with a phone app?
    Yes. The HL668 pairs over Bluetooth with the HIDALIFE app, where you can add and remove codes, set auto-lock timing and check entry records. Remote control away from home needs the optional Wi-Fi gateway.
    Can I keep a physical key with these locks?
    Both models include a keyway, so you can still open the door with a traditional key if the batteries run down or you forget a code. The keypad and app are additions, not replacements for the key.
    How long do the batteries last on a HIDALIFE lock?
    HIDALIFE rates the locks for roughly a year of normal use on four AA batteries, with a low-battery warning on the keypad and in the app. Cold weather and frequent motor use shorten that.
    What warranty and returns apply to HIDALIFE locks?
    HIDALIFE covers its locks with a limited one-year warranty against manufacturing defects. Return windows and conditions are set by the individual store, so check the seller's policy before ordering.
    Are there HIDALIFE discount codes?
    Deal.ai checks what HIDALIFE products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
