Nissan AGC Decode / Is it true that you can stick them in the Freezer to Decode?

This one always makes us laugh, but there was once a brief element of truth to it. Back in the very early days of the Radio Code development, (maybe day two or three), some of the Integrated Circuits (Code Eproms) used on pre-production models were not of a very high standard, and if they were used outside of their normal operating temperature range (ie:cold), they would no longer retain the programmed Code data, and the unit would briefly switch on for a split second before it died completely. (This was pre-production models back in the early 80`s).

But although technology has moved on, the old Wives tale remains. But think about it. How can a sophisticated electronic component self interrogate itself and magically display a heavily encrypted security number, by getting as cold as February? But still people try it! And boy, do we laugh when they do.

If you put your Car Radio in the freezer, before long all of that bare and unprotected metal will appear white and frosty. The display may also have frozen, expanded and cracked by this stage. But the real fun starts when the unit thaws out, as all of that ice will turn to rust and corrosion almost as fast as it melts. Your expensive Radio has now been reduced to a pile of furry orange scrap, for want of saving a few quid on Decoding. 
But Hey! Don`t panic! As we are more than happy to supply you a brand new one!
