In 99.9% of cases you can't as the electronics are integrated.
That is why they have the different codes to select.
To replace the frequency you have to replace the transmitter and rceiver with something suitable - I tried with several of these systems and only an old one from the 80's with pure analog technogoly could be changed a little bit - IMHO not worth the hassle.
