I remember there was a time that stock radios we programmed with an anti-theft logic in such a way that if they lost the power source, they will automatically lock out requiring an unlocking code from the dealer.

I need to do some work on my 2006 Mazda 3, and for that, I need to unplug the battery. My concern, and thus question is: if doing so, will it lock out the stock stereo? and thus require me getting an unlocking code from the Mazda dealer.

You should have the code, usually in the handbook for the car or on a metallic or plastic tag.

If it has been lost then either you can get a "code saver" which plugs into the cigar lighter and stops the radio loosing its code - warning this does not work on all models - do check.

Or, you can go to the dealership and they can, either for free or a small (usually) fee sort the correct code for you.

There are some people advertising the same service on the www, but be careful... some are good others...

  • The vehicles for which the "code saver" are unlikely to work are those which do not have a live convenience outlet when the key is off. – fred_dot_u May 16 '19 at 21:44
  • @fred_dot_u have one permanent live and one switched on my car - factory done, just make sure you know which is which... – Solar Mike May 16 '19 at 21:45
  • Good point. I realize now that my aft compartment has a live-always outlet, while the dash version is key based. – fred_dot_u May 16 '19 at 21:46
