There were dozens of booths at the recent ALOA show in Dallas and each one had something to sell. I was initially attracted to the Sunnect booth for several reasons. Sunnect is marketing the AP501 digital deadbolt lock. While there are other digital locks on the market, the Sunnect lock caught my attention because it looked like a quality piece of hardware that customers would like to have on their doors. While some digital products may look like add-ons, this lock had the look of original equipment.
