The locks in the house have been a bit of a mystery for a while. The original company, Sargent, isn't making home locks anymore (actually, they never really did) and the original styles are long out of manufacture.
We've found a Schlage lock/knob that's a good replacement, but the smaller bits and pieces are harder to fit together -- for instance, how can my 40 year old sliding door handle lock work with this new Schlage key?
This is where Craig at Rex comes to the rescue. We worked with Rex in Berkeley for our old place and loved them and were glad to see a Rex literally "just down the street" at 3511 Clayton Road.
So, if you're a Concord Eichler owner, Craig is the one to see... he's a great knowledge of the homes and how the locking systems (and that remote entry system) work.
