The fingerprint sensor is quick and accurate. App control is very convenient and allows temporary guest codes. The lock feels durable and high quality. Installation was straightforward.

Great battery life
I love it. It works well when my son needs to get in the house and I’m not home.
This door handle is amazing. We've been using it for 11 months and have had no issues. The fingerprint recognition has worked every time.There's 4 ways to use the locking mechanism on this handle, i.e., fingerprint recognition, key, 6-digit code and companion app. All these methods work great.It's heavy duty and well made. The handle feels good in your hand. It's powered with AAA batteries. The power in ours hasn't drained in all these months. There's an emergency USBC port that can be used if you do lose power. If you don't have a power source, you can still get in using the key. However, it tells you when the batteries are low so you should never need to use auxiliary power. The app also shows your battery life. It has voice commands that can be toggled on and off. It also lights up so you can use the code feature.Installation is easy. It fits a standard doorknob cutout. Programming wasn't too difficult either. You download a companion app and program your users. It walks you through setting up the fingerprint recognition for each person as well as setting individualized codes. The app also allows you to control the lock remotely. If you're away from home and you need to let someone in, you can unlock the door for them using this app. There's also an option to use a voice password for unlocking. You also receive alerts through the app if someone's trying to get in. It also monitors when the lock was used and by whom.This lock is incredible. You can't go wrong. It looks great and it works. I was apprehensive about using this. I was afraid there would be issues like it not reading the fingerprints or running out of power. I had nothing to worry about. Now, after using it for almost a year, I'd never use a regular door lock again.
Aesthetically appealing offering nifty features like retina scan, fingerprint access and door bell with a second remote chime. However, the chime of the doorbell doesn’t chime to a complete resonance. The lithium battery needs to be charged every 4 days… annoying. And the whole thing must work with wi-fi.
Pros:Customizable passwords for each family memberConvenient fingerprint recognition (though I haven't personally used it, the Hubby thinks it works great)Secure and reliable locking mechanismEasy to install (according to my husband)Cons:Lack of Wi-Fi connectivity for remote accessDim keypad buttons that can be difficult to see in low lightVerdict: The ARPHA Keyless Entry is a great addition to any home. Its customizable passwords and secure locking system make it a valuable tool for keeping your family safe. While I would appreciate Wi-Fi connectivity and brighter keypad buttons, these minor drawbacks don't significantly detract from its overall performance. If you're looking for a reliable and convenient keyless entry solution, I highly recommend it.
