I have followed with great interest the several discussions about wireless keypad locks. Based on research and the advice here I settled on the eRentalLock system, which I was excited about due to the ability to set wirelessly and the Schlage name, until I realized it was not going to fit on my door because it is too narrow (an inch or less, though I haven't yet been able to measure it). We live in a historic neighborhood, so replacing the door is not an option. Does any one have a recommendation for wireless keypad locks for thinner doors? Thanks in advance.
