My garage door opener is from Steel-Craft Door Products Ltd. 1/2 H.P. Security+ Model 1255SCR. The instructions that came with the new keypad were clear and concise on how to install and program the new opener. In fact, I had the new keypad installed and programmed in less than 10 minutes. It was just that easy.
