    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.

Customer Questions & Answers

  1. Answered by the admin 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.
  2. Answered by the admin Yes, this lock is compatible with the Cormax Best core. When purchasing be sure to choose the "Best" core option for the right model.
  3. Answered by the admin 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/
  4. Answered by the admin

    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. 

  6. Answered by the admin

    Yes you always have free egress from the inside. 

  7. Answered by the admin

    For changing the codes to this lock you can follow these instructions: simplex-1000-l1000-changing-the-code-kaa1163
