Keypad door lock with 50 user codes, IP66 rated
A keyless entry door lock that opens with a code on a backlit touchscreen, with a mechanical key as backup.
4.6 from 60 buyer ratingsWhat it does
This keypad door lock opens your front door from a code on a backlit touchscreen, so you walk up with groceries in both hands and type instead of hunting for keys. It ends the spare key under the mat and the key ring that goes everywhere with you. It holds up to 50 user codes, one for each person who needs in. Inside, the bolt re-locks itself behind you and a thumb-turn opens the door.
This smart deadbolt lock replaces the deadbolt on a standard exterior door. The exterior unit has a backlit touchscreen keypad above a key cylinder. The interior unit holds the batteries and a thumb-turn. You open the door by typing a code on the keypad, tapping the lock or unlock icon, using the mechanical key, or opening it from the app.
Installation runs through the door bore. The exterior and interior units clamp together with the mounting plate, and the bolt extends into the strike plate on the frame. It is made for doors 35-50 mm thick with a 2-1/8 in bore, a 1 in edge hole, and a 2-3/8 in or 2-3/4 in backset. The handle direction reverses to suit the swing of your door. The lock runs on dry batteries, so there is no cable to a wall outlet.
It suits a household that wants a code on the front door and no key ring to carry. It holds up to 50 user codes, and the option shown here bundles an IC (RFID) card for tap-to-unlock. It does not replace a lever handle or a knob, because it is a deadbolt with an interior thumb-turn. There is no fingerprint reader and no camera on the front panel.
Ships from China with tracking. The estimated arrival range for your country is shown next to the price.
- Give every person their own codeThe touchscreen holds up to 50 user codes, so each person who needs in can use their own number. The panel is backlit, so the digits show up when you get home after dark.
- Lock and unlock without digging for keysTap the lock or unlock icon on the touchscreen and the bolt retracts or extends. A mechanical key fits the cylinder below the keypad, so a flat battery does not stop you getting in.
- The door locks itself behind youThe bolt re-locks itself after the door closes, and a low-battery warning tells you when the dry cells need changing. Inside, the thumb-turn throws the bolt by hand. Nobody has to remember to lock up on the way out.
- Fits a standard exterior doorIt fits doors 35-50 mm thick with a 2-1/8 in bore, a 1 in edge hole, and a 2-3/8 in or 2-3/4 in backset. The handle direction reverses to suit the swing of your door.
- Keeps working when the power goes outThis password door lock runs on dry batteries, with no cable to a wall outlet, so a power cut does not take out the keypad. The exterior panel is rated IP66 and is made for a doorway that takes rain and dust.

nstalled this electronic door lock and it exceeded expectations. Setup was simple, instructions clear, and build quality surprisingly solid for the price. Fingerprint recognition is fast and reliable, and the keypad is responsive. Battery life seems good so far. Great value, secure, and convenient for everyday home use. Terrific, thank you!
The lock was shipped quickly and arrived quickly. IC card is not included in the package. Everything is working correctly, as per the instructions. Opening options: - 13.56 MHz key fob (not included in my set); - standard key (two included); - digital code (6 digits are entered on the keyboard);
I belive this is really good stuff. I am happy with my purchase. But I have to install it and use it for a while to now. As you can see I tried it and eveyting works as it should. This is my theird one. Thanks to seller and the fast delivey. Recomended.
The programming was not easy, as it was necessary to repeat and try again several times to ensure that the codes were taken into account. Patience is required! ! ! Time will tell if this lock lasts...
This is good stuff. I have already left a review. But I have to try it on my doors once again before I really know for sure.
just got it delivered, and the lock itself is damaged. lock unusable.

Questions
Will it fit my door?
Yes, if your door is 35-50 mm thick with a 2-1/8 in bore, a 1 in edge hole, and a 2-3/8 in or 2-3/4 in backset. The handle direction reverses, so it suits either swing of the door.
Is it hard to install?
No. The exterior and interior units clamp together through the door bore with the mounting plate, and the bolt extends into the strike plate on the frame. This keyless deadbolt door lock uses the standard deadbolt prep most exterior doors already have: a 2-1/8 in bore and a 1 in edge hole.
Does it need wiring or a plug near the door?
No. It runs on dry batteries and has no cable to a wall outlet. The lock warns you when the battery is low, and the mechanical key opens the cylinder if the batteries run out.
How many codes can it hold?
Up to 50 user codes, one for each person who needs in. The option shown here also bundles an IC (RFID) card, so you can tap the card on the lock to open it instead of typing a code.
Does it have a fingerprint reader or a camera?
No. The front panel has a touchscreen keypad above a key cylinder. There is no fingerprint scanner and no camera on it, and inside there is a thumb-turn rather than a lever handle or knob.
Why does it ship from China?
We buy from established suppliers in China, and they ship your order straight to you. The trade-off is time, so you see the estimated arrival before you pay.
Will I pay anything when it arrives?
Possibly. Import duties and taxes for United States aren't prepaid yet, so the courier may collect them on delivery. Nothing is added to our price at checkout.
