If I am reading this right, you have one keypad with xxxx as the code that controls GDO 1. Then you have another keypad with the code zzzz that controls GDO 2. You want to set both to xxxx.

Yes, you can program the same code in each keypad. The keypad only controls the garage door it is programmed to. I have 2 keypads that use the same code on 2 different garage door openers. It doesn't matter what the code is. Each pad is set up to work with one garage door opener. If they were not set up that way either keypad would open both doors at once, regardless of the entrance code.

You got it!

Thanks, I will re-program both when I get back this weekend.
