new clocks and radio problems

[Scottymk4]

Hey Guys, changed the battery the other day and now the radio has lost its code, I was told it gets the code from the clocks...is this true as I changed the clocks ? if the answer is yes can i put my old ones back in and allow the radio to get the code then change back to the newer ones without needing to do any coding for the clocks ?

thanks as always for the help
