Q: Why does the ND40 stay locked after egress?
A: There is potential for ND40/ND44's manufactured around March 2011 to remain locked after egress, or after the latch is depressed. There was an issue with the keycam that created a bind when locked. This was resolved in April 2011.
Q: Please describe the procedure to perform the ND40 and ND44 button installation.
A: The ND40 outside emergency button and the ND44 outside emergency turn button can disengage from the lever and fall out when they are not assembled properly.

Q: Why is the ND lever hard to push on?
A: ND locks shipping on or after January 30, 2017 no longer require the use of the soft durometer spacer. Lever installation on the redesigned ND locks should not be difficult.
For ND locks shipping prior to January 30, 2017, the addition of the soft durometer spacer (SDS) on August 15, 2012 did affect the installation of the lever. Ultimately, removing the amount of wobble is a more aesthetic and user friendly feature, but will require a bit more attention when the lock is installed. The best way to ensure that the lever is fully attached, is to listen for the "click" of the lever catch when it's installed. A helpful tip would be to push the lever on firmly at the spindle, and push the furthest point of the lever towards the door, ensuring a "click".

Q: Are the ND, NDe, AD and CO levers the same?
A: As of June 2019, all ND, NDe, AD CYL and CO CYL levers are the same. Between January 30, 2017 June of 2019, the AD and CO cylindrical lock levers were incompatible because of the ND / NDe lever and spring cage design change in January of 2017.
Prior to January 30, 2017 the AD CYL , CO CYL and NDe levers were the same as the ND .
The AD and CO mortise, mortise deadbolt, or 993 exit trim, levers are different and unique to the AD and CO line.
