Replaced Batteries in Kwikset lock and now Unkown.

[PhanTomiZ]

Hello,

Installed new batteries in my Kwikset 910 lock and now the device is unknown.  Node details and Network Details look good, but cannot retrieve association groups.

I don't have much time to play with this at the moment, I just need it to work.  Any ideas, as to what I should try first?

Already tried Heal, Repair Links and Synchronize to no avail.

Thanks in advance

P.S.  I want to leave the Add/Remove Z-Wave device as a last resort because I may have to remove the lock from the door and bring it closer to the ISY.

Hi @PhanTomiZ,

Please try Z-Wave | Tools | Synchronize … I suspect your door lock has lost all its memory.

With kind regards,
Michel

Thanks for the response,

I decided to spend some time on getting my lock back on line.  These are the things I did before doing the obvious.

1.Change batteries
2.Replaced batteries from Ni Cads to new alkaline.
3.Heal, Repair and Synchronize;  multiple times...

Seeing how I was getting nowhere, I decided I would exclude the lock and re-include it without taking it off the door, knowing full well I would eventually have to take it off the door and bring it closer to the ISY.  

I selected "Remove/Exclude" and ran down to the door and hit the "A" button and it turned red.  (not a good sign I thought).

Ran back to the ISY to find that the lock was now recognized by the ISY.

Replaced the alkaline with my Ni Cads,  moved one of my Siren repeaters to a different location and ran a few Heals.

All is now back to normal. 

Can you tell me what may have happened and how I fixed this?

P.S.  For anyone else reading this I use Ni Cads (Costco special 1.2V 2500 MAh Duracell) which last 6 months and 500 to 600 lock cycles.  I believe longevity is dependant on the quality and condition of each individual cell, which I have yet to match.  New Ni Cads battery level show up as 60% to 70%

@PhanTomiZ,

Thanks so very much for the details. Unfortunately, I have no clue! Does not make sense at all unless the door lock was somehow removed from the network without ISY knowing it.

With kind regards,

I just noticed that I have the same issue with my Kwikset locks... Likely started when I switched the zwave controller out for the 500 series one.... Since then the emails (that I haven’t been paying attention to! Oops...) have had a blank battery status...

[PhanTomiZ]

Dead batteries will do that. 

I'm fortunate to say that my cycle for all three doors is pretty much to charge them in May and Nov.  It only took three years to figure that out too...
