Maverik Posted May 29, 2023 Share Posted May 29, 2023 Hi folks, I can't help take this to a slight extreme, trying to install this genuine Discovery radio unit but its locked, anyone got any recommendations for radio code retrieval? The Web is flooded with people offering code services just not a clue who to use. Cheers Mav Quote Link to comment Share on other sites More sharing options...
smallfry Posted May 29, 2023 Share Posted May 29, 2023 I have used this guy a couple of times, not for LR stuff though, but always solved the problem ! https://www.ebay.co.uk/str/dndservicesltd/Radio-Decoding-Services/_i.html?store_cat=3 Quote Link to comment Share on other sites More sharing options...
Happyoldgit Posted May 29, 2023 Share Posted May 29, 2023 Sticking it in a freezer used to be an old trick didn’t it? Quote Link to comment Share on other sites More sharing options...
simonr Posted May 29, 2023 Share Posted May 29, 2023 Sticking it in the freezer for 24h is likely to work. The code is stored in CMOS memory with a battery backup. The battery voltage drops with temperature, so you get to a point where the battery voltage is too low & the memory forgets it's content. Normally you can see a button / coin cell on the board. De-soldering it, waiting a few mins & re-soldering is generally quicker & more reliable, particularly on a vehicle intended to be used in low temperatures. They may have used a battery with better low temperature performance. Quote Link to comment Share on other sites More sharing options...

smallfry Posted May 30, 2023 Share Posted May 30, 2023 I doubt it, but once you can get in, on every set I have had, you can disable the code function. However, you will have to have a read of the 750 page multilingual radio manual to confirm this. Quote Link to comment Share on other sites More sharing options...

Depending on the radio, it will either clear it or return to whatever the default was - something like 0000, 9999, 1234 etc most likely.
