    The parts I just received are exactly what was needed. Your customer service is superior to most other companies that I deal with on a regular basis. I will continue to “GoKeyless” and work with Ed and all your people. I appreciate the great service and variety of products you carry. The Simplex L1021 is perfect for our needs of restricting and controlling access to one of our Climate Controlled Storage Buildings.

    The lock continues to work well, which is a testament to quality since it is installed on an exterior door in Afghanistan…a very harsh environment.

    We are very happy with our purchase! Everyone loves the convenience of putting in the digits and being able to open the door without having to fumble for keys.

Customer Questions & Answers

  1. Q Does the lock come with keys also? answer now
    Asked by Paul Contreras on November 30, 2021 6:51 PM
    Answered by the admin

    This model does ship with a SFIC core included. The lock will include one change key (to remove the core) and two operating keys (to unlock the door).

  2. Q Can the plunger be reversed if the RH door is push or pull? answer now
    Asked by Rick on September 15, 2021 6:27 PM
    Answered by the admin

    The latch/plunger can be rotated to operate in either direction. 

  3. Q Will it work outside and get wet? answer now
    Asked by George Fidler on August 5, 2021 12:10 PM
    Answered by the admin

    This model is fully mechanical and can certainly be installed on exterior applications. 

  4. Q How do you remove the lock? answer now
    Asked by Rudy on September 10, 2020 11:00 AM
    Answered by the admin

    The removal of this lock typically requires the interior code change keys and the spanner wrench that was included with the lock. You may use the installation guide below to reverse the steps so that you may remove the lock from the door.

  5. Q How do you install new key core answer now
    Asked by Edward Eubank on April 18, 2018 4:28 PM
    A An interchangeable core should come with a key that is called your control key. This key is used to install and remove the core from the lock.
  6. Q Is this lock compatable with a Cormax Best 6 pin core answer now
    Asked by James Eler on March 2, 2018 9:23 AM
    A Yes, this lock is compatible with the Cormax Best core. When purchasing be sure to choose the "Best" core option for the right model.
  7. A No this is not compatible. We would suggest an LP1020 with a Von Duprin 99 panic device. Please see the links below. https://www.gokeyless.com/product/simplex-lp1020-pushbutton-panic-exit-lock/ https://www.gokeyless.com/product/von-duprin-99eo-rim-panic-exit-bar/
  8. A

    Unfortunately this lock will not work with your current door configuration. Depending on the room and width of the door we may have some other other options for you. Below I have attached a product that may work in your situation.

    Yes, you can change the code as often as necessary with this lock. However, long term it would be recommended to look into an electronic lock such as the E5031 as changing codes in electronic locks are more forgiving for errors and will allow you to add and delete codes faster. 

  10. Q Does this allow free exit from inside? answer now
    Asked by Jim Kinne on December 26, 2016 2:05 PM
    Answered by the admin

    Yes you always have free egress from the inside.
