Hello, I hope this helps someone save some money like I did!
I had an att digital life system years ago and still have the yale real living lock that I bought with the system.
I could still use the codes but no remote access. With my new HE hub I gained full control remote and alexa integration again!
here are the steps
you have to unpair the zwave module first
start HE exclude z wave device
then un pair
To unpair your Yale lock y need to first Unpair it. Do this by unpairing on the lock itself.
Begin with the device locked. If needed for touchscreen models, place your palm on the screen to wake it up
Enter the 4-to-8-digit Master PIN code followed by the # or gear key
Press 7 followed by the # or gear key
Press 3 followed by the # or gear key
it will say exiting network
Then put it in pairing mode:
Begin with the device locked. If needed for touchscreen models, place your palm on the screen to wake it up
Enter the 4-to-8-digit Master PIN code followed by the # or gear key
Press 7 followed by the # or gear key
Press 1 followed by the # or gear key
start z wave pairing
it will add and you will have full functionality to add and delete codes
you will have to change the master and code 1 at the lock however I think
