How to Adjust MM3 Latch

How to adjust the Command Access MM3 Latch


Steps to adjusting the MM3 latch adjustment ("Push-to-Set") are quick and easy with no tools needed, but an assistant can be helpful.

Reasons to adjust the MM3 are:

  • Push-pad isn't sitting correctly - is retracted with the lodge bolt hanging out
  • Push-pad is loose and there is movement


MM3 Adjustment:

1.   Press the push-pad in with your hands and hold it to the new and desired location.

 2.  Have assistant apply power (while you are still holding the push pad) and wait for a series of 6 beeps.

3.  Wait for 6 beeps to finish, let go of the push-pad.

4.   Have your assistant release the power & push-pad will re-fire and set in its new location without anymore movement.

 MM3 Diagnostics:

2 Continuous Beeps = Over-voltage, over 31V.

  • Readjust your power supply to the operating range which is between 22 – 30V.

3 Continuous Beeps = Under-voltage, under 20V.

  • Readjust your power supply to the operating range which is between 22 – 30V.

5 Continuous Beeps = Forced release (push-pad has been knocked out of place).

  • Device will automatically re-fire.

6 Continuous Beeps = Unplugged/Switch wires are not making contact.

  • Unplug power.
  • Check connection and make sure all wires are connected and pinned correctly.
  • Reconnect power.
  • Hold push pad down and re-fire to new location.

7 Continuous Beeps = Push pad can’t re-fire due to an obstruction.

  • Remove obstruction and make sure push pad moves freely again.
  • Hold push pad down until beeping stops.
  • Release and re-fire.


We hope these steps help you adjust and diagnose your MM3 module quickly and efficiently.
