Dover unit / t-111 / G E drive / vintage approx.1986
looking for entry plus/ push button key pad for security input codes /fits impulse car panel slot. Sound elevator was original manufacture .

Sound elevator was a fairly large independent based in the pacific northwest. Puget Sound..Thus Sound Elevator. They were bought out by Dover, who was then bought out by TK. They did support some of the old Entry Plus stuff at one time, but I do not know if they do anymore. Your best bet is to contact TK.

T k response is the stock on the shelf is all that's left . And T k not supporting the product no longer . Possible a alternative method / solution . T k suggested digi key this type of key pad was special design and no longer supported . Interface solution would be really nice at this junction . I bielive it's matrix input . C1/c2 two roe's of keys 1-9-0 / a ten key configuration .
