User questions & answers

Question:	I have a deadbolt about 1 inch above my door knob. In order to use this, do I have to get rid of the deadbolt since it's so close to the knob
Answer:	I literally switched my regular door knob with my deadbolt they fit perfectly opposite with each other and then had the deadbolt on the bottom and the ultra lock on the top instead of the way it was previous and it fits wonderfully looks very aesthetic and works incredibly well that's the way to do it...
Question:	I would like to see the template to make sure this would work on my front door
Answer:	You can download the template here. https://www.u-tec.com/files/download/21/UL3%20Drill%20Template-V1.5.pdfAlthough Ultraloq is a latch lock, according to our customer survey, more than 50% install Ultraloq on their front door. Ultraloq doesn’t cover the deadbolt hole completely if you would like replace your existing deadbolt and knob / lever. However, there is a quick solution. What most customers do is a swap - install Ultraloq on the top hole and put the existing deadbolt on the lower hole. If there is no existing deadbolt or you want to remove your deadbolt, most of them will get this accessory in Lowes or Home Depot to cover the top or lower hole, depending on which hole you install Ultraloq. There is an Amazon review for your information. This customer installed Ultraloq on the lower hole. You also have the option to install it on the top hole and put the plate on the lower hole.https://www.amazon.com/review/R1V20VA6ONLTIP/ref=cm_cr_dp_title?ie=UTF8&ASIN=B01ILD4I3C&channel=detail-glance&nodeID=502394&store=photoHope this helps!
Question:	What is the backup method to get in? I don't see a key anywhere and what if you need to get in and say the battery is dead... What options
Answer:	Hey Chris! The hidden key hole is positioned at the bottom of the lock, which gives extra security in case of key hole hackers. You can always use your mechanical key as a backup.
Question:	Can I add access codes or check the log when away from my house via app, or do I need to be within Bluetooth range
Answer:	I want to know if the wifi features are now available. Because I am also interested to set codes via app far away from my home. Thank you very much.
