Automate 2 RF events

Hi,

I have searched but can not quite find what I am looking for and seek some help.

I want to automate 2 events.

  1. Opening a 'common gate'. This is currently performed by button 1 on programable RF key fob.
  2. Opening 'my garage door'. This is currently performed by button 2 on a programable RF key fob.

I have access to both the receivers to allow a module to be programmed/coded legitimately.

I'm looking for a setup to have a bluetooth event from an iPhone trigger the ARDUINO to send the appropriate RF signal to open.

The BT modules are easy enough to find but I am having difficulty working out how to do the RF part.

Thanks in advance for anyone who can spare some insight.

Another thread with the same topic at http://forum.arduino.cc/index.php?topic=50873.0 might be helpful.

The most reliable means may be to buy a second key-fob (that you know works) and wire the pushbuttons up to some digital outputs from the Arduino.
