GoKeyless is a trained and authorized Lockey® dealer. Sales, service, and support. It's why thousands of clients around the world choose GoKeyless™ for their security and access control needs each year. This all mechanical dual-sided lock can be used to begin a new keyless entry system or expand an existing one.  When you free yourself from keys you completely eliminate the hassle of having to deal with them.  Everyone knows keys just get lost or misplaced - who hasn't bellowed "where are my keys!" What if you could always have your key on you.  Get the 2835-DC today and you will.  It lets you program in a secret pass-code that you, your family, or your employees can all use.  Your time (and money!) will never again be wasted looking for your keys, or waiting to be let back in.  How secure is it?  Put it this way, your existing locks that lend themselves to key-bumping, and unlocked or propped open doors, are hardly keeping you safe. Your current locks - because of keys - are a risk.  A new lock like the 2835-DC is 100% bump-proof.  There is no key hole. What if it fails?  It won't.  This lock is the result of 30+ years of functional testing.  It doesn't fail.  There are no secret techniques you can use on the push-buttons to 'knock' the lock open or determine its cipher. Well chronicled in security and law enforcement circles is the fact that the majority of crimes - resulting in theft, injury, or even death - are crimes of opportunity.  A door that is not always locked, or that can be bumped open invites crime. Customizing your access with innovative door hardware like the 2835-DC is a prescription for security success. Where can this lock be used?  Typically on gates, and openings where access must be controlled on both sides of the door, such as in a jetway, healthcare facility, or on a residence door that has sidelight panels.  Families with special needs children or parents with alzheimers, may also find a two-sided lock like the 2835-DC helpful to prevent wandering. From the inside you can set it to the same pass-code you use for entry, or a different one.  There is even a passage feature built-in.  This is useful for when you don't want everyone to have to put in their code.  At the touchpad you can quickly change the lock's function from normal, to hold-open mode.  The door will latch shut, but not lock.  This will come in handy at your next office party when you have your clients and vendors in.  Also great for your kids' birthdays so you don't have to give out the code to the parents and their kids. Use the 2835-DC to upgrade your key in knob or key in lever locks.  When you have a deadbolt above your knob, we recommend replacing the deadbolt with the Lockey 2210DC.  For situations where you need the door to auto-lock each time, you could remove your deadbolt altogether, and then use a cover plate behind the 2835-DC.  The plate will cover up the hole left by your deadbolt.  To meet codes, the levers on both sides are full-size and comply with the American's Disability Act.  The levers cannot be forced or kicked off. Installation on common doors won't take you any longer than vacuuming out your car - and about the same amount of effort.  Requiring only one extra screw hole, you'll be able to show off your new keyless entry the day the lock arrives.  Should you be installing on an exterior door, you won't need to worry about the elements.  Heavy rain, snow or ice won't phase it.  Extreme warm or cold has no effect.  Even a highly concentrated salt-air ocean environment won't cause it to lose its form or function.

    REALLY great, and a good value. Don't hesitate.

    It took us forever to find a double sided lock for our gate (we have a gated vestibule in a downtown area), and we needed a lock that could be safe from both sides, so passersby wouldn’t be able to reach around and open the door. We also were happy that this lock was not dependent on batteries, AND that our blind 7 year old son could easily unlock it (many new locks lack physical buttons that a blind person needs). This lock hit all the high points, it wasn’t difficult to install, and the handle opens smoothly.

    I ordered this amazing double lock for a modified antique gate (which I purchased the lock box that fit perfectly for these locks that was welded onto the gate). I LOVE them! I had to call to get assistance to install, but discovered the pin was not in properly (wrong side) and the bar thingie had to lean the other way. Simple corrections, please call for help, don’t struggle, kind thoughtful technical help is there to assist calmly and knowledgeably. It is quite a beautiful site to come home to, like commercial security should be. The handles open with a slight touch, quite ADA approval! I paid for the code to be pre-set, it was well worth it to me being handicapped with stiff hands. Now if I can just teach my Service Dog the password! Lol.

Customer Questions & Answers

  1. Answered by the admin

    Yes, 2835DCJB - Jet Black

  2. Answered by the admin

    Yes, as long as you do not use the passage feature the gate will always lock whenever it closes. 

  3. Answered by the admin A gate box is needed when the lock you desire to install will not mount or is not prepped for the gate to be installed on. This allows you to have a properly prepped surface for the lock install.
  4. Answered by the admin Unfortunately, there is not. These locks are not adjustable locks when it comes to the width sizing of the door to 1" thickness. We would suggest the use of a gate box for this type of installation. Please see the link below. https://www.gokeyless.com/product/kbxdig23-gate-box/

    The 2835 lock comes with an adjustable 2 3/8″ and 2 3/4″ backset, so you're covered for both.

  6. Answered by the admin

    Unfortunately, there are no fail safes for fire with doublesided locks and they are typically not in code in the majority of places due to life and safety concerns. We offer them for gates however, people are free to install them on homes at their own risk.  However, for those who have used these on their homes they tend to put in only a three digit code on the inside and generally all together like 123.
