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 Alzheimer’s, 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.

    I was looking for a 100% mechanical lock. Can’t stayon top of battery charges or battery changes, one opportunity for a hard wire here. Easy to change tumblers too. Good price, nice product.

  5. Altogether - Good Lock

    Louisa Day (verified owner)

    The lock is working great now. We had a few problems with the installation but with the help of Treavor at Lockey, we got all the problems solved. The only problem I see in the future is having to change the keycode tumblers. You have to remove the lock (both sides) to do that. I got stuck and had problems putting the lock back together again. I had to pay a lock professional to do it for me properly. I also found out from the technician at Gokeyless, that the keycode works in any combination of the numbers chosen. We had already changed the tumblers to get another code. So, you can technically change the sequence of the code (e.g. 1234 or 4321, 3241, etc.) for the purpose of saying the code has been changed without changing the tumblers. That works for my purpose.

    It works pretty well. Seems durable. We use it because we have an autistic child who likes to run out of the house without supervision.

  8. I have a Mixed Review

    Judge Bellamak (verified owner)

    The latch did not work smoothly and the spindle became bent while trouble shooting. After many emails with your service tech (Ryan), we discovered the problem and a new latch and spindle were mailed to me. All working now. There is a lot of play in the operation of the handle. It feels like it could be forced open (when locked) which could bend the delicate spindle again.

    I want to commend service tech Ryan for helping me trouble shoot the problem and quickly send me the needed replacement parts.

  9. Good but could be better


    Wish they would have manufactured it to be replaceable in a standard cylindrical prep hole. You can make it work but it’s not great. Other than that seems to work great.

  10. So far I love the locks

    Rita (verified owner)

    I needed the locks for heavily (few times a day) used security gates. So far the locks have been working great. They were reasonably easy to install, which I did by myself. I only needed to hire a welder to attach the gate box and the strike plate, and he did that in only a couple of hours.

    The C button acts as your clear to clear any keypresses made at the unit. The Y button will activate passage mode when this is depressed along with your combination. The X and Z keys have no function and can be used as part of your combination. 

  2. Answered by the admin

    This lock will only support one access code at a time. If you are looking for a lock that will take multiple codes for entry, we recommend looking into an Electronic lock model. 

  3. Answered by the admin

    The 3835DC is a heavier duty model compared to the 2835DC. 

  4. Q Do you have this lock with a key on both sides as well? answer now

    A key override kit can be provided for this unit if desired. For more information, please contact our sales team at 937-247-9327, option 1 or at [email protected]

    This should fit without protruding over the top of the gate box as the Lockey 2835 is 5 1/2 inches tall from bottom to top. If the gatebox has 5 inches of clearance from the center of the borehole, this should be enough clearance to mount the lock without issue. 

  6. Q Hi, what’s the difference between the 1150dc and 2835dc? answer now
    Asked by George Christides on May 30, 2019 10:36 AM

    The 1150 is a commercial lock while the 2835 is a residential lock. We would recommend that you speak with our sales department to ensure that you are getting the best lock for your needs. 

  7. A

    Yes, you can set one side or the other to passage and keep the other side locked. 

  8. A

    It only comes in the Satin Chrome Finish. 

  9. A

    Yes, you can use the STI 6521 as a cover. 

  10. A

    Yes, you can change the code at any time by removing the lock from the door and changing the pin code tumblers. It typically takes about five to ten minutes to change the code depending on your setup.
