    Simplex 1011 key less lock is an easy to install lock system each took 10 minutes to install no issues. GoKeyless delivered on time and packaged well.  Thanks for an easy solution.

  2. Buddy from New Hampshire

    To be perfectly honest the installation of the keyless lock is not complete. I was somewhat / very disappointed with the fact that the new lock did not fit into the existing holes in the door. So either the current holes need to be plugged and new holes drilled; or the door needs to be replaced again with new holes being drilled. Plugging the current holes is the most economical approach but the plugs need to be custom crafted another painful exercise.

    Answered by the admin

    You can purchase the 2 3/8 backset on our website to go with the standard version of the 1011. 

  8. Answered by the admin

    Yes, but for multiple changes we would recommend going to an electronic lock such as the E2031. 

  9. A We do sell extension kits. Please give one of our sales representatives a call at 937-247-9327 option 1
  10. A Unfortunately, this lock is not designed for that type of function. There is a model, however, that does allow you to lock out the keypad from use. Please look at the link below for more details.
