ThorBolt Fingerprint Door Knob, Keyless Door Knob with Keypad Biometric Electronic Thumbprint, Auto-Lock for Interior Doors for Bedroom, Home, Office, Garage, 4xAA Alkaline (NOT Included), MD1 Black

We had a need to secure several interior doors and wanted a combination door handle that doesn't require a key. I was so pleased with this product that I ordered five and they have all worked consistently well. All my installations were replacements so I was able to save the original strike plate and I didn't have to use the supplied guide to make a strike plate. After figuring out that the assembly required disassembly first I went from 45 minutes on the first install to 10 minutes each. As shown in the photos the unit comes fully assembled and has back-up keys along with a strike plate if needed and templates when boring the door hole. It's very important that the door is the correct size as cited, and to adjust the screws with a manual phillips head and not an electric screwdriver in order to avoid over-screwing. The handle is made from sturdy material and it not likely to break without a lot of effort. The four AA batteries that are not included make the keys light up whenever touched making it easy to enter the combination in minimal light. Finally, it can be set up to use a finger print, which I haven't done. If I have problems doing that I'll update this review, otherwise, my opinion is that the user will be very happy with this product. Each the internal and external knobs extend three inches from the door.

Handel has been above expectations. Biometric reader is accurate and opens instantly. Looking t buy another one!

Muy buena calidad y funciona perfecto

Unequivocally one of the best electronic door locks on the market. I reviewed several options before deciding to purchase the MD1. I am happy with my decision because the THORBOLT door lock is well-designed, offers thoughtful features, is easy to install, and is the right size. Backup entry options, i.e., a key and USB power for the situations where the battery dies, is noteworthy. Also, if you use your access code instead of fingerprint, you can enter up to 20 digits along with your access code so onlookers won’t figure out the code. You also have the ability to turn off the auto lock feature, which locks the lock after five seconds, and enable passage mode. Additionally, you can set the lock to quiet mode. The fingerprint sensor is accurate; ensure the sensor and your finger are dry and clean when using fingerprint for entry. If you need a realizable and easy to install electronic door lock, fit for purpose, the THORBOLT brand should be at the top of your list. It’s worth every penny!

I purchased the Thorbolt Biometric Doorknob from Amazon without expecting too much, but I was pleasantly surprised, this product truly exceeded all expectations! From unboxing to installation, the entire process was incredibly smooth. The instructions were clear, setup was quick, and programming the fingerprints and codes was surprisingly intuitive. The design and ergonomics of the doorknob are top-notch, it feels solid, looks sleek, and fits perfectly with the existing hardware theme in our home. The finish matched beautifully, almost like it was custom made for our space. Functionality-wise, it’s a game changer. We now have enhanced security and peace of mind, especially knowing our room stays off-limits to the kids when we’re not around. I also love the flexibility of being able to program multiple fingerprints, permanent and temporary access codes, and even one-time use codes, an awesome feature for guests or service providers. This doorknob has added not only security but also a touch of tech-savvy elegance to our home. I’m already planning to purchase additional units for our office and garage door. Highly recommended for anyone looking to upgrade their home security with smart, stylish, and reliable tech. Thorbolt knocked it out of the park with this one!
