I'm assuming you are asking about the wall control station (has open/close, light and lockout buttons). It will continue to work since you won't be disconnecting it.
There are two wires that go from the 75424 Receiver to the garage door opener. Those two wires will go into the same slot in the opener that the wall station connects to. If you notice the wall station not working check and make sure those two wires have not come loose from the opener.
