Can you hack a 4-Button RF Remote Control???

[radivent]

So I bought the Keyfob 4-Button RF Remote Control - 315MHz (http://www.adafruit.com/products/1095), and a momentary RF receiver to go with it. Here is my dilemma: The project I am working on needs to have four input buttons to communicate wirelessly with a receiver. When the buttons are pressed in a specified order, the receiver plays a song through a piezo buzzer. I got this all working nicely using the 4-button key fob and momentary receiver. However, I would like to rig the buttons up to something a little more "substantial", e.g., four arcade buttons such as these: http://www.adafruit.com/products/1185. Is there a way to hack the keyfob so you can control the A, B, C, D transmissions using bigger buttons? Any help is appreciated.

The chip in the FOB is in a DIP package and the data sheet gives the pinout and a reference circuit diagram showing the button connections. It should not be difficult to solder in leads from your arcade buttons.

Unfortunately Im still a little confused. As I understand the pinouts on page 3 of the PDF datasheet (http://www.adafruit.com/datasheets/PT2262.pdf), it looks like pins 10-13 are used for the button signal lines, and each is attached to ground pin 9 on the other side. But its not that simple, is it? It looks like I also need a 2.7K ohm resistor between the individual pins and each button, and then also need 10K resistors looping back to ground? I'm not great at reading schematics, so any help would be great.

Not sure if the fob circuit is identical to that one. But if you wire your switches in parallel to the existing switches, you can use any existing resistors on-board.
