    The 3210DC and 3230DC locks with the double sided keypad are excellent for use on gates to prevent un-wanted entry from either side. The locks install easy and are easy to set the code.

    I am an architect, and therefore try to plan ahead more that a lot of construction people. I have not yet built the gate and installed the hardware. I have looked at the products, and they appear to be everything I hoped for.

    I recently purchased my second keyless gate lock from GoKeyless. I had purchased the first one – a Lockey 3210DC, several years ago, and have found that I couldn’t do without it. It has performed flawlessly, and weather has had no effect. So I ordered another one for my second gate. Ordering online was easy and it shipped quickly. Thanks again for a great product and excellent service.

  1. Answered by the admin

    This is a purely mechanical lock and has no electronics to illuminate the keypad during the night hours. 

  2. Q Can each side have a different code? answer now

    Yes, each side has their own combination that can be set. 

  3. A

    It is a deadbolt so you will need to throw the deadbolt anytime you close the gate. If you would like something that locks behind you, you will need to go with a latching lock such as the 3230. 

  4. A

    No, these cannot use double digits and you can use any length from 3-6 digits. 

  5. A The gatebox that you would be looking for is the GB 2500. Please see the link below. https://www.gokeyless.com/product/kbxdig23-gate-box/
  6. A No, the gate box is not included. If you are looking to install this on a chain link gate we would recommend the Lockey 2900 series lock and the corresponding gate box to go with it. Below we have attached the links. These two items meet the standards required for a chain link installation, as opposed to the 3210 which would need custom configuration. https://www.gokeyless.com/product/lockey-gb2900-chainlink-gate-box/ https://www.gokeyless.com/product/lockey-2900-keyless-throwbolt-lock/

    This lock's handing is reversible. All you'll need to do is change the slot the 1/4" tall pin goes into on the interior escutcheon and it will work for your gate.

  8. A

    Since this is a fully mechanical lock, no batteries, no electronic parts, it supports one code that would need to be shared. If you need to provide a temporary code for maintenance we suggest changing the code immediately after they leave. The lock operates on a pin and tumbler system so it will not fail, and the manufacturer is confident it will not fail, which is why no key override. 

  9. A

    Since this is a mechanical lock and only accepts a single code at a time it does not have the internal computer to know if someone enters the wrong code multiple times. It does however due to the mechanics keep the door locked until the wrong codes are cleared and the right code is entered.
