Have you ever experienced the despair that you lose your set of keys or you can’t search through the bag for the key in a hurry?

Some people may hide a key under the doormat, flowerpot or even the garden path.

But if you think about it seriously, you will find it isn’t safe at all. If someone copies your key when you are out, you wouldn’t find out at all.

An electronic door lock may be the best solution. It allows you to enter your home with codes.

And we highly recommend Signstek PLU331 Electronic Door Lock to you.

With Signstek electronic keypad deadbolt lock, you don't have to worry about forgetting to lock your door. Its auto-locking function prevents any incomplete locking and the Mute Function prevents code stealing.

The programming is foolproof: keypad 1 stands for 10s，3 for 20s, 5 for 30s,7 for 40s,9 for 50s.

Pretty nice – by Teddy Phillips on December 28, 2021

Update: Easy to install, strongly secure, the codes work.

Works like a charm – by Shelley Bowen on March 23, 2020

I installed this lock 5 days ago and so far it is absolutely excellent. It was very easy to install and even easier to program. I have it installed upstairs by the deck and the kids kept locking themselves out. Know, they can easily enter with the correct code. We have the auto lock set to 30 seconds, so the door is always locked for safety.
The price was great, the delivery was fast, and the product is excellent.

Excellent, Works Very Well and Very Easy to Install! – by Brian M. Edwards on December 6, 2019

This was a breeze to install, easy to program and works perfectly.
It also has a bright green illumination and the motor seems to open and close the deadbolt with ease, suggesting that the batteries will last longer.
It also comes with 2 keys.
If you are looking for a simple budget "smart" deadbolt, this is well worth considering...

Looks expensive and works awesome – by DAMIAN FPV on January 22, 2021

Absolutely love it. It is 4 degrees here in Wisconsin today and the lock works perfectly, had a huge ice storm, and the buttons never froze up. Easy to program and the finish is very appealing and durable. Will purchase a second assembly for the front door.

Great for retrofitting hand-made doors – by KO on March 15, 2020

I installed this on a nonconventional, hand-made wood door in our basement. The installation was straightforward and the functionality is outstanding for the money. It works simply and lights up well for nighttime use.

Smart Door Lock – by Sissi on November 15, 2018

Compared with traditional mechanical lock, the smart features are very useful. I frequently had incomplete door locking problems in the past, now, as the lock can detect, my door is much more secured.
Even for the adults, we do not need to worry about leaving the key in house and being locked outside. Backlighting is a very practical design, especially when you come back home late in winter like now.

Very easy to install as replacement – by Cheryl Mills on April 18, 2020

Used this product to replace stubborn deadbolt on the front door of our vacation cottage which is about 90 minutes away. Took less than 10 minutes to install and about another 5 minutes to customize the settings. Gave us better peace of mind regarding security.
