      I have a remote Elk M1KP2 (addressed) key pad for a back door, the system has worked for 5 years without this issue.

      Anybody having this issues, seems to have just popped up out of the blue.

        Does the keypad display Keypad Addr #2 Lost COMM? If so then this keypad has lost communication to the M1 Control. Double checking the wiring at the keypad and the M1 and perform the Bus Module Enrollment

          <div>Good morning</div>
          <div>Thank you for your prompt response to my question</div>
          <div>The key pad only displays a “Key Pad No Comm” doesn’t include the address.</div>
          <div>This Key pad is keypad located at the backdoor.</div>
          <div>The system was installed 5 years ago, this is the first technical issue that I be had.</div>
          <div>Should the Key Pads address show on the display? If not, would that indicate the the address is lost?</div>
          <div>If lost, would I need to “reprogram the address, connect my laptop to the panel & reenroll same?</div>
          <div>Wiring is good, any suggestions would be appreciated.</div>
          <div>Thanks & Best!</div>

            If the keypad is displaying Keypad Loss Comm but is working as expected then there is another keypad on the system that has lost communication to the M1.

              I was finally able to get access…I checked the main lobby key pad address 1

              It has been removed, I called the owner he came out…have me the kep pad also handed me a capacitor…I don’t know if it just “popped” out of the circuit board or what happened. I checked the circuit board, it looks like it may C19 it’s smaller than the other Capacitors.

              I am going to order a replacement…if I had a schematic & could confirm the socket location, figure out the polarity I would try to resolder the capacitor. Not sure if this is the cause or if it’s a coincidence.

              Any thoughts?

              Thanks for your patience!
