The best advice, don’t do it!
Normally if you have just one Schlage lock you can easily re-key all other non-communicating locks using z-wave Schlage manual key as a “master” key.
Things get complicated if you have two z-wave locks, you have to disassemble second lock in order to remove lock cylinder and replace pins.
I brought both locks to Lowes and the key guy reluctantly agreed to try. He also sad that Schlage advised against rekeying their communicating locks.
Anyway, he was able to re-key all my locks, but when he opened z-wave lock he found a “spare part” and he had no any idea how it was used in the lock mechanism. I brought lock home, paired it with Vera and tried to open/close via Vera. Well, didn’t work. I tried buttons on the lock, both with numbers and open/close. Didn’t work either. Manual keys worked just fine across all my locks.
I could simply bring it back, exchange to another one and try to rekey again, this time in the Home Depot, but I decided to try to fix it myself. It took me almost three hours and two pounds (I skipped my “supper”).
Findings:
-
The “spare” part, small unthreaded bolt with the spring happened to be the actual locking bolt. I lost the original spring and used spring from the ball pen. Ball pen spring is much stronger then original so I had to try several times cutting pieces with different length.
-
The entire locking mechanism seems to be very feeble. The main driving part is a small electric motor with a long spring attached to the rotor. This long spring acts as worm transmission moving plastic part that engages with the locking bolt.
-
Assembling lock back is not trivial, you have to place plastic part with a small pin at a certain position, inserting pin into the rotating “warm” spring. Same thing, countless errors and trials.
Finally it worked, but I would be better off doing it again.
