If I wanted to build a new transmitter for this old receiver, How would I match the frequency and code ?

I already gave the TS the $4 solution above......
It's easier and cheaper to buy new transmitter and receiver, than to try make transmitter for this
This is what I've rigged up to operate my door for now....lol...pretty cool huh ?
I also found these....https://www.ebay.com/itm/433Mhz-
Done , Thanks MikeML and nyaknyan and jpanhalt. I ordered 2 of the 315MHz. Do they have to be programmed ? I've seen examples, seems like basic computer programming language. So I'm basically telling the receiver that when it receives a signal to apply a small voltage across the push button actuator wires thus opening the door.
