Why don't we show the price?

Retailers like GoKeyless have the legal right to set their own prices independently, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's "minimum advertised price," the manufacturer does not allow us to show you our price until you take further action, such as placing the item in your shopping cart. The steps required depend on the details of the manufacturer's minimum advertised price policy. Taking these steps allows GoKeyless to show you our price consistent with our goal of always offering you the best buying experience.

This won't require you to purchase the product. You can easily remove it from your cart if you decide not to buy it.

Sunnect AP501 Reviews

The installation and programming of the AP501’s was simple. It was the only deadbolt that we could find with an automatic throw which was very important for our handicap client. The client seemed to like them very much. I would recommend this product to a friend.  Joe, Dan Vos Construction Company, Ada, MI

Purchased two AP501 locks. The first lock was installed in an old (in place for more than 55 years) entry door, the lock installed and works flawlessly. The second lock was installed on a prehung Pela entry door. The autolock feature doesn't work apparrently because the gap between the frame and door is too great. Overall these are the best keyless locks on the market!  Robert from Maryland

Piece of junk. It locks the door alright. The Auto Lock won’t work anymore. The alarm doesn’t work anymore. The alarm went off constantly and then finally broke. So I have to lock and unlock manually, no alarm . . . spent a lot of money on this thing and it is NOT what I paid all that money for. Could have gotten something much cheaper that did not have the bells and whistles . . .since your bells and whistles don’t work anymore. . . and I still paid for them. Disappointed. Would go with a cheaper model and get what I paid for next time!!!  Kate from Illinois

We are very happy with the lock. We feel safe and the keypad feature keeps my husband from locking himself out of the house, which is a huge relief.  Karen from California

I purchased the Sunnect AP501 Electronic Door Lock System, and in took me ten minutes to install it, and has been invaluable, meaning valuable, to my home. My grandmothers caregivers no longer need to lose keys, and everyone/everything is safe and secure with the auto-lock feature. I use the Key fob for myself, while others use the pad, which is easier on them. I am comfortable knowing that if I need to change anything, I can do it easily and discreetly. Thank you for this lock!  Andrew in CA
