Unless someone else has one with a different brand name but same FCC ID, it
will be next to impossible. Perhaps you can contact the manufacturer and
they can tell you where to find one.

OTOH, building your own is not entirely beyond the realm of possibility. The
only thing not shown on the schematic is the value of the oscillator
resistor and you can get that from one of your remotes. They use a Holtec
encoder chip and 315.54MHz. The Holtec chip is well documented and small
315MHz SAW controlled transmitter modules are readily available.
