MiLocks TKK-02SN Tkk-Sn Digital Door Knob Lock with Electronic Keypad, Satin Nickel, Keypad, Keyless

Easy to install and use. We purchased 2 and one came damaged. We got it replaced quickly. We have had them for months now and haven't had any problems. They are a nice sleek design and great keyless entry for any room. My husband set the codes but it looked easy enough. The instructions were pretty clear and easy to follow.

Purchased 8 2022 mounting was easy fits standard door. It is now 2 2025 lock still working perfectly had to change batteries twice recommended to use a quality battery regular alkaline didn't last long put some Energizer max lithium and been in there for a year still working good. I use door daily sometimes multiple times. Easy to change code, instructions on back of battery lid. Over all good buy would buy again

10/21/2019: At least one other reviewer has posted a safety issue with this lock, and honestly, I didn't "get it". But after installing one of the two locks purchased, I'll reach out to the company and if not satisfied, return them to Amazon. In my opinion, these locks are paramount to a death-trap for families of young children.HYPOTHETICAL:"You wake up in the early morning hours, thoughts foggy from your sound sleep, to an unusual smell and in the distance, your ten-year-old child screaming 'IT'S HOT, HELP ME PLEASE!' Instinctively you tell your child to run to the door and get out, but then you hear your child, gasping for breath between the tears of terror: 'BUT I CAN'T TURN THE DOOR KNOB. IT WON'T TURN!'"Yup, when this lock is in it's "idle" state, you cannot turn the doorknob to let yourself out despite the strength of the 10 strongest person's on the earth. Why? Because first you have to turn the little dial in the center of the knob first (surely easy to do under stress, fear-of-death, and sheer-terror...{sarcasm}), and that allows you to turn the doorknob and unlock the door.HISTORY: Locks nearly identical to this used to be sold by a company called "Morning Industry Inc.", with the same address and phone number as listed for this item. However, it is very easy to tell the difference: The original door knob lock assembly had a metal battery cover with a small screw. The new (junk) version battery cover has no screw and is made of plastic. Without much research, it seems that "MiLocks" has aquired "Morning Industry Inc.", and is now selling trash for product (just look at the other reviews).IMO, it appears that the engineering design of the product was significantly minimized (to reduce cost/increase profit), at the expense of customer lives, and as of this posting the company is listed as having 5 employees. Frankly, 5 employees are five people to stuff things in boxes and order crap from china/japan/Korea.But in fairness, I will contact the company after posting this review and see what they say. However, please be aware of this "internal locking" design WAS a problem with the original company ("Morning Industry Inc."), and they subsequently came out with a much safer always-open design, meaning whether the door knob was locked or not, someone inside could evacuate simply by turning the doorknob handle (no need to mess with the lock knob).I promise to update this review, especially after requesting technical support from the company, after this review is posted. It is possible that there is a mechanical setting (not listed in the manual) that allows the door to be opened from the inside without significant dexterity, but I'll wait for them to explain their product first.Otherwise? I CANNOT recommend this product and plan on returning the two purchased promptly.UPDATE: 10/24/2019I called the company and they confirmed that these locks are NOT intended to be used on doors that require emergency egress. Doors I could think could use this lock include a company supply closet (minimize theft), a detached garage side door (exit available from the normal garage door), or a storage shed/barn (places where people typically don't live in, and/or typically have multiple exits).The company offered to take my contact information to notify me when (if?) a safer version becomes avsilable.Both locks have been returned and credit issued.

The lock works well. The problem I had was it would not fit properly because it was too long. The distance between the lock and the dead bolt is too close causing it to hit the dead bolt. My holes in the door are 5 1/2 inches center to center, pre drilled from the manufacturer. Too close for this lock, I had to install the inside part upside down, and modify the dead bolt cover. Other than that it works great. The instructions for programming it are a little funky, use the ones inside the cover, they are easier.

My foster/adopt children have conduct disorder and keep breaking into my room, breaking my things and stealing money. I haven’t had a good nights rest in a long time. Thank you, now I can finally sleep at night.

I bought this lock 4 years ago. The lock was great but I didn't bother to rate and leave a review, until now.I used the lock for more than two years at my previous (rental) place. The lock was solid. It looks nice, easy to install and I didn't need to replace the battery the whole time. Note that I locked and unlocked the door only about twice a week. Since I used it for my room, I don't care much about how easy it is to pick the lock. :)Anyway, I moved about one year back and just realized I lost the keys for this door knob. I went ahead and contacted the support via email. They respond quickly and offer me the replacement keys for free since I am located in California.Definitely will buy from this brand again.
