Review: Good Quality, great value. - This was reasonably priced for a biometric (fingerprint) lock. The installation was, without doubt, the easiest door knob/lock mechanism I've ever installed. Setting up the lock was very easy also. Again, the easiest setup of a fingerprint door lock I've ever had. So far during testing it has performed exceptionally well. It hasn't not read my fingerprint yet. I've had a less than stellar experience previously with biometric locks but this one has really out performed anything I've had in the past in price,performance, and ease of installation and setup. I am using it on an exterior door protected from the elements under a 6ft porch and a storm door. I'm happy to have found this product and will update if necessary after some use. Review: Defective metal hardware, missing USB charger - I’ve purchased two of these handles for interior doors. The first was easy to install and works perfectly so I ordered a second handle for a different interior bedroom door. The inner square-shaped bolt on the second handle was poorly casted and would not fit through the slot, so I had to buy a small metal file to file the edges so that it could be installed. After installing, I also noticed that the micro USB slot was completely missing on the inside handle. The hole is there on both sides, just like my other handle, but one side is empty and only has the hardware on the outside of the door to recharge it, which is very inconvenient for me. The first handle I received can be charged on either side. Also, the beeps are REALLY loud compared to the first handle I purchased, which is very annoying as it’s in a bedroom hallway and can be heard in the other bedrooms every time I open it. I would’ve sent it back as a defective item, but by the time the holidays were over and I had the time to install it, I was way past the return window. If my second handle worked as well as the first, I’d have given 5 stars, but the second item is clearly defective. I’m very disappointed in the second handle that I received, so unless it can be replaced or I can get refunded, I’m only giving 2 stars at this time. I was considering buying a 3rd & 4th handle for the basement/rec room doors, but now I will look for a different brand of lock because of the hassle I had with the last one. ***EDIT: I’d had these door handles installed for less than a year with very little issues. Then, on the SAME EVENING, both handles gave a series of beeps and stopped working. I thought both the batteries had died but they wouldn’t recharge after 5-6 hrs of using a long usb to a wall outlet and a number of portable power banks. I was locked out of my bedroom the entire time until I managed to pop the lock with a credit card and finally break in at around 4am. My poor cat was locked inside my bedroom for hours because I couldn’t get the door to open. After I uninstalled both of these door handles, they continued to randomly beep a series of beeps now and then but neither of them would re-charge or read any fingerprints! I don’t know what happened to them or why they both decided to break in the exact same way within about an hour of eachother. Needless to say, I will not be re-installing these handles not purchasing replacements of this brand because they are clearly defective. I am also lowering my rating to 1 star because these are junk and useless to me now. ## Features - ★ FIT ANY DOOR: Replaces most standard U.S. door locks, both fit left & right handed doors.

HL1 model.** A: The first fingerprint is the master user. When other one want to add their fingerprint, have to verify the master fingerprints first. **Q: is the reset button seriously on the outside?!? So basically bypass lock with paper clip?** A: No, it’s not just the paper clip, it would also require a registered finger print, otherwise it will stay locked. **Q: I would like dual-sided fingerprint access. Can this be done?** A: Yes. I have programmed each of my fingers, and every member of my household has both of their thumb prints scanned. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Quality, great value. *by L***N on March 11, 2019* This was reasonably priced for a biometric (fingerprint) lock.

I installed it within 5 minutes, and that's including removing my old manual lock, and installing this lock! It looks simple, modern and elegant! I love the simplicity of the lock! It was the easiest door lock installation I've ever had to do. However, after I programmed my fingerprint, I was NOT able to program my family members' fingerprints. I tried a dozen times. I had them read the manual, and tried it again and again, but it just wouldn't program anyone else's fingerprint. I contacted the seller, and he tried to email me back a couple of times with additional instructions. It still wouldn't program anyone else's fingerprint! The seller immediately sent me a replacement, and this time it worked like a charm. I was able to immediately program all of my family members' fingerprints! I'm ecstatic. I just love the way this lock looks! I love the simplicity of it! I love that I don't have to worry about keys, and I love that I don't have to remember yet another passcode....I also love that if it runs out of battery, I can use a power bank and charge it! SO I never have to worry that I don't have replacement batteries if it dies! Thank you, Harflo, for your prompt reply and resolution! I'm so so so pleased and satisfied with this purchase! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/61647911-hl1-fingerprint-electric-smart-door-lock-biometric-keyless-entry-door](https://www.desertcart.us/products/61647911-hl1-fingerprint-electric-smart-door-lock-biometric-keyless-entry-door) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-15*
