GoKeyless™ is a factory trained and authorized Kaba Simplex® dealer. Sales, service, support, valid warranties. It's why thousands of clients around the world choose GoKeyless™ for their security and access control needs each year. Turn your home, small office, and other light traffic doors keyless with this upscale new keypad lock by Kaba Access.  At a price where you want it, the new Simplex LD450 series allows you to manage your day's business instead of managing keys.  You may have cheated losing your keys or the accidental "I locked myself out!" up to now, but why leave it to chance any longer.  For less than half the cost of an iPod or internet-enabled phone, you can have this light-duty, wire and cable free keyless lock on your door in minutes.  You'll never have to worry about whether you remembered your keys ever again!  Don't be fooled by similar looking locks at a cheaper price.  Some companies may claim to be offering you a lock, and rightly so, but is it a secure locking device. Cheap knock-off locks can be compromised with the right know-how.  This one by Kaba easily passes the test in durability, and reliability.  The inside and outside housings, as well as the knob, are solid cast.  The pushbuttons are all metal.  These are important construction concerns for long-term operability, and for installing the lock on a perimeter door, shed door, or any outside entryway that may be impacted by weather.  The LD450 endures.

  1. Awesome lock

    J (verified owner)

    We used similar locks on our ship in the Navy, so I already knew it would be robust and easy to use. Can’t go wrong with these. Perfect for keeping kids out of my bouldering climbing gym when I can’t be up there to supervise.

    This lock would be right at the maximum size. For something that narrow we would recommend the M230 and for a gate if they can reach over the M230DC which is double sided to stop reaching over openings.
