HuTools KS02 Finger Print Deadbolt Lock Oil Rub Brz

Update Aug 2024: I bought my first HuTools door lock in Jan 2021 and installed AA batteries from Costco. Three and half years later, it is still running on the same original batteries. Ours is a high traffic home, so door lock is in constant use multiple times a day. And I configured it to auto-lock after 30 seconds and it has worked flawlessly. Thank You HuTools for such an amazing no-frills digital key. I will buy few more soon. Original Review: It took me 15 minutes to remove my old lock and install the new lock. A day before I got my delivery, I got an email from Hu Tu Tools with a PDF of instructions - I followed the instructions and I was up and running in a few minutes. The instructions were very clear - the only problem I had was I had to keep walking to my desk to re-read the instructions and made mistakes on my end - once I followed the instructions, it was great. It took me more time to remove the old lock than to install the new one. I changed the auto-lock from default (99 seconds) to 30 seconds and verified it worked. Luckily for me, the lock fit my existing lock hole perfectly - I did not have to do any cutting or chiseling or anything of the sort. MY door is 1 3/4th" thick and it worked perfectly. I tried the lock and unlocks with the door opened a few times because I did not want to get locked out and once I was happy with the results, only then closed the door and let the deadbolt lock. The dark bronze color matches perfectly with my door. I am going to add more codes for rest of the family members and also make a copy of the master key just in case the battery dies and I get locked out. I researched for months to buy one to unlock/change codes from remote location but chose this for a) low cost b) I don't need remote access for my primary residence. This may not be good for vacation homes or Air BnBs where you will have to add/remove codes from remote - you have to be at the lock to add/remove/change codes. I will monitor for battery consumption and will update. I am hoping it will give a warning light before I have to change the 4 AA batteries it takes - only time will tell.
