It is an urban myth
“Putting a stereo in the freezer wipes the security code.”
Another long-running rumour. When the first-ever security-coded radio arrived in the Eighties, someone found the memory could be wiped if it was subjected to temperatures below -20 degrees Centigrade. Then, any code could be entered and the stereo would work.
But DC Elliott said: “The manufacturer quickly fixed the problem and it hasn’t worked on that or any other stereo since. This hasn’t stopped people still trying it, though. And doing this mostly results in another part of the stereo – usually the LCD display or CD player – breaking and rendering
the whole unit worthless.”
