Radio Shack has a Rcvr/Demodulator made by sharp that will pick up the
remote signal that is pulses modulated at 40Khz and output an inverted
ttl signal that you should be able to invert and send to a 555 timer to
remodulate it at 40Khz and send it to an I/R LED inside the cabinet. 

The module costs about $3.50
