WARNING, DO NOT BUY FROM TAPPLOCK. I know these locks are cool, but the technology is not quite there yet, and Tapplock does not offer a warranty to match the limited lifespan of their product. I purchased 2 of the original locks about 18 months ago. Both locks are used a few times a week on a gym locker (hardly heavy use). The Morse code and Finger sensor suddenly stopped working on one of the locks. I tried desperately to find a telephone number for Tapplock because like I said, the Morse code and finger print will not open the lock. (did I mention my phone was in the locker along with my wallet and car keys). Well, no number could be found, I had to wait about 2 hours for my wife to meet me so I could unlock it with her phone. Anyway it has been about 6 days since I reached out to Tapplock via email (it takes hours and sometimes days for them to answer your question with another question that you had anseered in your original email because you knew thay would ask. Anyway ther eresponce is they canot help me, but here is a 25 off coupon for a new lock. ( I almost choked on my tic tac when I read that) Could it be they really wanted me to purchase another lock for $75? I tried explaing to them, that my $100 is now of no value to me since I must have my phone to use it and I dont always have my phone with me and that it was only 18months old. I also tried explaining that the main selling point of the lock was that it can be opened with a fingerprint. Why would they try telling me to use morese code or my phone? (still waiting for a reply onthat one) how could a $100 items main feature be expected to last 18 months only? Clearly something went wrong, be it defect or other reason. How would a new startup company not stand behind a recenetly out of warranty item. Well. It is what it is, but I feel obligated to let others know my story so they dont throw $100 bucks down the toilet. If not for the fingerprint, I would continue to use my 30+ year old Dialpad Masterlock. (damn technology got the best of my wallet again!) The jist of this story is to STAY AWAY at least until they change thier policy to stand behind thier products.
