in this video I'll go over one of the
methods used to unlock GM radios the
owner of this vehicle bought this with
an aftermarket radio he wants to restore
it back to factory he picked up a used
radio which is of course locked to the
VIN of the truck that it came out of in
this video we're going to attempt to
unlock it I'm going to start by
identifying and removing the EEPROM on
this radio the EEPROM is an ST nine
three five five zero nine three at this
point we could just leave the EEPROM off
and the radio would be unlocked but the
preset functions wouldn't work we want
this done right so we're going to try to
actually change the numbers in the
EEPROM next you need to take the EEPROM
and put it in an EEPROM reader make sure
it's sitting in there good you'll need
to read it as a 24:08 you have to make
sure that not only the pin it is right
but that you set the EEPROM reader up
right
now it is read the data I'm going to
save it
standardized radio lock and it's now
saved on the SD card okay so now I can
put this in my PC next open up your hex
editor drag and drop the file you just
pulled off of your SD card and I named
this one radial lock now what you're
looking for is the last line these six
numbers here are the VIN number and
we're going to change it to the correct
event of the vehicle that's going into
you okay I'm going to save it as I'm
going to give it a new name just radial
okay I'm gonna put it back on the SD
card and go from there so now I have the
modified bin file saved back on the SD
card install that back into my EEPROM
reader and go through the functions
again and reborn' the new program onto
the EEPROM
again you're programming this as a 24:08
even though the number is ste nine three
five five zero nine three okay so now
I'm going to recover and I'm going to
select radio that's what I named it at
it's just radio lowercase there it is
right there let's see if it will take it
yes I'm sure I want to restore it
there now we have the new dump on the
EPROM now the only thing I have left to
do is install this EEPROM back in the
radio unfortunately this customer needed
his truck back yesterday I don't no
longer have a radio so I'll have no idea
if this even works but hey if you guys
have tried this let me know in the
comments down below if it actually
worked thanks for watching
