## Description

Mechanical Keyless Deadbolt, Satin Nickel Adjustable Deadbolt.

Review: Outstanding quality and durability - I’m writing an updated review because after 8 years of use, this deadbolt is still working perfectly. It was easy to install and has been exposed to harsh weather conditions in a tropical climate (strong sun and heavy rain) with minimal impact. Aside from a few minor cosmetic stains, it has held up extremely well. You do need to be careful when changing the code, as there are small internal pieces that can be easy to misplace, but once set up, the lock requires virtually no maintenance. About once a year (or every couple of years), I simply clean it and apply a bit of WD-40 to lubricate the mechanism and help prevent rust. In a time when many products don’t seem to last, this deadbolt truly stands out for its durability and reliability. If I ever needed another one, I would absolutely buy this again. The value for the money is outstanding.
Review: Build quality that is very very rare these days. Made in Japan. - My unit came with an extra red "code" pin which allowed me to increase the number of code digits to 5. That is, 5 out of 12 number would need to be guessed. Also, the number of combo digits would need to be guessed, which further expands the problem space and thus the inability for one to "crack the code". As others have mentioned, it actually does not matter what order you enter the numbers. You can even enter number simultaneously which I actually like. It makes it faster for me to enter the code; instead of 5 presses, I just do 3 -- two of the presses involve two simultaneous digits. If you want to calculate how difficult it would be to crack, you would consider this a combination (i.e. n-choose-k) as opposed to a permutation problem. Traditional keys can be bumped or picked, though there are now bump-proof locks. At the end of the day, all household door locks are deterrents. If one were determined to get into your home, he/she would simply kick the door in or break a window -- easy enough. You might be better off securing your high-value items in a safe that is bolted to the ground. This thing is made in Japan; it ain't cheap to manufacture there. I'm no metallurgist but I suspect that the machine screws are stainless steel. The bolt is machined brass. Build quality is amazing. Even the stamped parts are very precise. The word "digital" the is casted into the front is cheesy as hell but it is just an "engrish" moment IMO. In Japan, I'm sure they think it is cool. In the U.S., it just looks cheesy. You will be able to adjust the left- or right- handedness of the unit depending on how your door is hung. It will require unscrewing a few screw and moving a pin. They even provide you a pair of tweezers (also used to set the code pins). All internal components seem very well crafted. Yes, I said "crafted". This thing was most certainly required human hands to assemble. There are QA stamps and screws are color coded to aid in modifying the unit. no batteries required. purely mechanical. Possible downside for others....configuring the unit was somewhat involved. This is no plugin-n-play thing. It is no Apple product. I am an engineer by trade. Let's just say that I made a fantastic evening out of messing with this and figuring out how it all works. Not all will enjoy doing this. overall a fantastic product.

## Questions & Answers

**Q: How do you lock this lock from the outside? Do you have to enter the code to twist the lock prior to leaving?**
A: When I had the same problem, it was because I put it on in reverse: I set it up for a right-hand door when it was a left hand door. When it is on correctly, you just twist the nob toward the door jamb to lock. Code only needed to open,

**Q: I really don't like the look of the black rubber that goes around the lock. Can the lock be installed without it?**
A: I can't imagine that it would fit properly without it. The black rubber not only creates a way to avoid scratching the door, it also makes the fit snug so that it doesn't shift (and the whole act like washers). Additionally, it holds the inside of the lock securely so that it doesn't move and stays aligned with the other side of the lock in the door jam.

**Q: how do you change the combinatin**
A: Here is the video (http://www.youtube.com/watch?v=aZj4zCIWxZE) that shows you how to change the combination. Good luck.

**Q: Will this work on a sliding glass door?**
A: Hello and Thank you for checking with us. The answer is no, the M210 will not work for sliding glass doors.  Please look at the Lockey 2500 or C150, either of these locks have the ability to work on sliding glass doors.

*by A***G on April 18, 2025*

Love it! Instructions were clear. It’s easy it’s simple and it works and it’s reliable. I have 2 of them. It fit right in my original dead bolt hole. So no need for drilling etc. the lock is smooth and I had it for sometime now and I am really impressed.
