    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.

  6. 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.
  7. 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.
  8. 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/

    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.

     
     
  10. A

    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.
