Dual-Sided Keyless Security to Help You Live More Effectively
It looks like the Lockey M210 from the outside, but this double sided M210DC model securely locks the door from the inside too with its two-sided keypad.  Entry doors with glass sidelights, families with special needs children, or seniors who may be prone to wandering, can benefit from the utility of double sided keyless locks.  Pool gates, marina gates, side yard gates, and virtually any gate application where you don’t want someone reaching over or through the gate to unlock it from the inside, is another prime location.  The GB-200-M gate box is available if you need a way to attach it to your gate.  Better than an ordinary two-sided deadbolt, this one doesn’t need a key.  Keys are the worst possible item you can lose.  Unlike a cell phone you can call, when your keys go missing, you have to empty out drawers, pants pockets, go through the laundry, rummage through the garage, check coat pockets, the car, the top of the washer and dryer, and your key hooks where you’re suppose to hang your keys but of course you never do.  Most people’s sets of keys are already too heavy anyway.  With this keyless lock you won’t make yours any heavier.

    The two-sided keyless entry dead bolt was a necessity for us. We have a 7 year-old autistic son, who is faster than the speed of light and when he gets angry, he runs for the door and can be outside and in the street before I can even get out the door. This product, while on the pricey side, has given us peace of mind. I did have an issue in that the code provided with the product was only good for the one side and the other side had a different code, but I wasn’t informed of that. I called the manufacturer and they were very accommodating and walked me through how to change the code so that both codes are the same, as remembering one code is hard enough. I would buy this product again if necessary.

    After drilling the hole for the bolt to go into, installation went well. The lock works well and is easy to open. I am planning to put in more of this style of lock except one sided only. Two sided was for a special application and solved that issue.

    We have been very pleased with our double sided deadbolts. We are working with a dementia patient that wanders and these have saved us a great deal of stress. Now that we have them I wouldn’t want to be with out them they are great.

    Nice hardware for the money. I’m glad I had a “Jack of all Trades” friend put it in. Very easy to key in the code and open the door. Nice lock.

    So far so good, bought 3 of these, delivered to Canada. Expensive to buy + expensive to deliver.

    I absolutely satisfied with this product. It is exactly what I wanted. Installation is not so hard and easy to operate. I have not tried to change codes yet but I guess it looks like not so easy to do it.

    Product worked well with one issue. If you are going to sell one that is push button on both sides, the security screws SHOULD be part of the original package, not a secondary purchase. I installed on an outside courtyard gate. Owner knows someone could jump the fence but did not want them to be able to carry things out through the gate. This was the install after I had to exchange the 2X3 on the gate for a 2X6 to handle the lock installation. I used a heavier latch plate that took 4-3″ screws to avoid a kick in.

    I purchased 3 double sided locks. All is working well with 2 of them. With one of the locks the “pass-through” function will arbitrarily engage at times when we unlock the door. To correct it we need to depress the “Y” button. This is problematic because you don’t realise the “pass-through” function is engaged unless you attempt to turn the handle. This issue happens about once a week. Not good

    I also purchased the easy install double deadbolt Lockey M210DC-EZ-SN Double Sided Mechanical Deadbolt, EZ Mount and it was anything but easy to install. I had to modify the assembly in order to get it to fit. The door was a standard metal door with a box.

Questions and answers of the customers

  1. A

    Yes, however, if you purchase the EZ version there is no need to drill an extra hole. 

  2. A

    Because this is a mechanical lock it will only use a single code at one time. You can however use a different code on each side if you so wish. 

  3. A

    The EZ mount allows you to install the M210 similar to a standard deadbolt so you do not have to drill any extra holes in the door to mount the lock which must be done if you chose the standard mount. 

  4. A

    Without seeing your specific locks it is difficult to tell you specifically which one would match the best. However, currently the industry standard for silver looking locks would probably be the Satin Chrome finish as it has a brushed silver look. Without seeing your locks this would be the best option versus the Polished Chrome or Satin Nickle. 

  5. A

    While it is not often that these locks fail if it was to do so it can be removed as long as you have access to the interior of the lock via another entrance. If no other means of entrance the lock would require professional removal. 

  6. A

    It is 100% weatherproof, and is specifically designed for that exact purpose. There is also a Marine Grade finish option if you are located in a salt-air environment. Lock is made with ZL3 zinc, which is extremely durable.

  7. A

    That is correct. You'll enter your code and then rotate the turn-piece to retract the deadbolt. As with all mechanical push button deadbolts, it will not automatically lock. The auto-lock feature can be found in some electronic deadbolts but unfortunately there are no two-sided electronic deadbolts on the market.

  8. A
    Unfortunately without modification to the gate or the post it cannot make that gap as the deadbolt will only extend one inch. If you have a metal gate you can purchase a gatebox and weld it closer to the post to cover the gap. You can also add a 1x4 or something to the gate to help close the gap if the gate is wood. 
  9. A Yes.  The lock if fully mechanical meaning it has no electronics so it can be used easily in the elements as the body is made from a zinc alloy. Heavy-duty neoprene black rubber trim plates are also provided with the lock for gasketing around the lock that helps make for a tight fit to the door/gate and help seal over the 2 1/8" cross bore, protecting the inner pin-and-tumbler mechanisms. For extreme environments you can also purchase silicone based lubrication to help protect and extend the life of the interior of the lock.
  10. A

    Yes this lock can use the combination in a non-sequential manner to open the lock i.e. 1234, 4213, etc. It is recommended to use numbers that are not near eachother though to enhance the odds of someone figuring out your code i.e. B052, 3702, etc. Even with the numbers being non-sequential you still have 10,000 possible combinations to use if you include the letters. If you need a lock that must use sequential numbers it is recommended to go with an electronic lock.
