in this video I will show you how to
unlock theft lock enabled radios for
General Motors vehicles from the late
90s into the early 2000s this is
applicable to Chevrolet GMC and Pontiac
radios that look similar to this they
can be CD or tape players they all have
the same procedure you'll know that the
theft lock is enabled if you try to turn
on the radio and it just says LOC on the
display and then the radio won't turn on
what this means is it wants you to enter
a code to make the radio work here's how
to retrieve the code first you need to
turn on the ignition key but don't turn
on the radio so we'll we'll do this
Pontiac one again this is applicable to
the Chevrolet or the Pontiac radios
you'll see it says LOC on the display
what you want to do at this point is
press and hold the number two and three
preset buttons and a number will display
on the screen just keep holding the
buttons
this says two eight two so now we're
going to write that down - eight - then
you're gonna press the am/fm button then
get your second number which is two nine
one so I'll write down two nine one and
this is all we need to do at this point
at the radio next you need to find a
telephone once you have found a
telephone dial the phone number at the
bottom of the screen this is the GM
dealership support line for Delco radios
you don't need to talk to anybody it's
just a recording once you dial the phone
number and you hear the recording start
enter one of the six digit codes at the
bottom of the screen followed by the
star key what these codes represent is
the dealership identification number
that you're calling from
not just anybody is supposed to call
this number you're suppose
to be a dealer so these are the dealer
codes if one of them doesn't work hang
up and try again with another one so
we'll start out and we'll put it on
speakerphone radio only invalid account
number please try again invalid account
number please try again code followed by
after so now you're going to enter the
two sets of three-digit numbers from the
radio so in my case it's two eight two
two nine one star so that's how you get
the code now we go back out to the radio
and I'll show you how to unlock it now
back out at the radio we need to enter
the code that the nice gentleman on the
phone gave us the code is zero one five
zero because the first number is a zero
we ignore that and we're just going to
enter the one five zero
in the display to enter the code you use
the hour and minute buttons again this
is the same on either Pontiac or the
Chevrolet radios on these radios the
hour and minutes are down here so start
with the minute button the minute button
controls the last two digits of the
radio so just start pressing the minute
buttons we want to go up to 50 and we're
almost there 50 and then the hour button
controls the next digit so we press that
once and it says 150 which matches the
code after this press the am/fm button
and it says security which means it's
the security is enabled and then you
press the power button and it works so
that's how you unlock a GM theft lock
