Poor quality plastic innards.... Welcome to the 21st century!
Reviewed in Canada 🇨🇦 on December 27, 2020
Update Feb 27/21 - down to 1 star. The internal gear mechanism jumped a tooth again. You can manually lock and unlock, but the powered internal mechanism will not work due to the gears being out of alignment. Will be lodging a complaint / return claim with Amazon as soon as I am done writing this update.
Update February 2021 - removing one star as the inner working gears some jumped a tooth (or something) causing the deadbolt to not retract/extend properly. Had to disassemble and re-align the gears. It is not difficult now that I know how it is done, but the initial troubleshooting and repair took over an hour. On a related note, all of the internal gears are plastic. Not sure how they will withstand the test of time. I would have preferred metal gears and their proven superior reliability and lifespan.
Bought this as a replacement for our 15 year old Taymor deadbolt, which seemed to not be engaging properly in its inner workings anymore. I was also keen to get something that would allow us to lock and unlock the door without having to fumble around with a key. This unit arrived quick. Had the same finish as our original lock set, and was easy to install. I was *almost* able to re-use the original key cylinder (and therefore keep using same key), but the flat metal "axle" (probably not what it is called) was about a quarter inch too short, so I had to use the key cylinder that came with the unit (loses one star on the thickness subcategory as a result).
Programming was easy. I really really love the one-press door lock button. I have not activated the automatic timed door lock feature, but it is nice to know that it has that feature.
As far as security, the new deadbolt seemed as thick and durable as the deadbolt it replaced, so that is essentially a wash. The only unknowns are battery life (i have read mixed reviews), and longevity of the electronics / physical mechanisms/ etc. If I can get a full year's operation between battery changes, and 15 years or more out of the device as a whole, I will be pleased.
