It's why thousands of clients around the world choose GoKeyless™ for their security and access control needs each year. The first time you gain a key free access using the Lockey 1600-DC double sided digital door lock you'll never settle for anything less again.  With a solid, one-piece front and back housing, this heavy-duty two-way keyless knob lock takes keys out of the equation, and features a 14 button operator panel on both sides for permitting in/out access to authorized code holders only.  The push buttons are stainless steel which prevents scratching, recessed for added security, and a heavy-gauge rubber grip ring is molded to the knob handle for a sturdy, comfortable rotation.  The knob also comes with a slip clutch built-in for preventing damage to the lock when unauthorized use occurs.   Recognized for their reliability and maximum security, Lockey double-sided Digital Door Locks are designed for a quick retrofit. You can use the 1600-DC keyless lock on any residential, or commercial doors which have an existing keyed-in lever or knob.  The 1600-DC is also great for gates because you don't have to worry about someone reaching over or through the gate bars and letting themselves in.  If this is your application, be sure to look at getting the compatible mounting box at checkout.  Install time takes about 30 minutes, and is typically a one person job, if you are comfortable handling a drill and screwdriver.  The 1600-DC keyless lock comes with a lifetime mechanical warranty on all the mechanical parts.  The housings are cast from alloy steel, and internal components are all stainless steel and teflon coated. This lets you use this lock in even the most extreme environments, including severe weather conditions, and areas with high traffic.  There is not much better than the 1600-DC in a single code double-sided keyless door knob lock.  You will find it simple to use, attractive in its appeal, and fun to show off to those who do not yet have one!
