OK. Yes, actually I have three locks (including “Garage Lock”) on one panel, and one lock on the other panel. All four are identical model Schlage locks.
I will use Garage Lock as a test lock. First I’ll see how many users it currently maxes out at; then I’ll remove it from the panel and factory reset it; then I’ll re-add it, and once again check how many users it maxes out at. I’ll let you know what the results are.
