Dear Glenn: I am trying to locate a remote-control lockset so that my wheelchair-bound mother will be able to lock and unlock her entry door from the living room. I haven't been successful in locating such a device.

-- Ron, Clarkston

Dear Ron: You don't want to open a door if you don't know who is on the other side. John at Smart Home.com, (866) 243-8020, suggested the company's Door Bell Front Door Answering System, item 5070. Mom can answer the door from her telephone (or cell phone) and open the door remotely.

If you just want a remote opening door lock, www.keylesspro.com has a large number of remote locks. A1 Electric Automotive Accessories -- (888)838-0506, www.a1electric.com -- has locks that can be opened only by remote control.
