Vehicle make/model = 1997 Chevy Lumina
Mileage = 135,000
Engine size = 6
work done prior = Battery/altenator were replaced.
work done to repair = Several 'guesses' were made as to what the code
might be.
tip/donation yes
tech = JK
question = Hi, is there a 'back door' to unlock the radio? Recently
had to replace the altenator and battery and the radio obviously lost
power. It has an antitheft device on it - it was probably a neat radio in
1997! Would just like it to turn on now!! Can you help? I am the
original owner but have no idea what the code is and there is nothing
written down in the owner's manual.

Thank for your tip/donation.
Here is what we need to unlock your radio.
With the key ON, hold the #2 and #3 presets until a 3 digit code is displayed. Write these
numbers down. Press the am/fm button, and a second set of numbers will be displayed.Write
these down. If 2-3 do not work, use the 1-4 buttons.
Then i will need to call in these numbers and get an unlock code. I will instruct on how to
enter the unlock code.
If however, too mnay attempts have been made to enter in an icorrect code, the radio may
display INOP. If it does, you will not be able to get me these numbers, as it is in a secondary
lock-out mode. You will have to leave the key on without touching radio for at least 1 hour.
Be sure to have on a battery charger if car not running. After the 1 hour, do the procedure
above to get me the 2 sets of numbers, then we can unlock it. I will wait for your reply.......

Your factory back-up unlock code should be XXXX
Enter it in the way you tried before. Here is the procedure.....
Unlocking/ deactivating unit with back-up code or customer code.
• Press the HR button until the LOC disappears and OOO appears on the display.
• Set the first two digits (01-19) of the code with HR (hours) button.
• Note: As if you're setting the time of day you will not see the 0 in the far left side. Example;
if the first two digits of your code is 02 you will scroll with the HR button until 2 appears on
the display.)
• Set the next two digits (00-99) of the code with the MIN (minute) button.
• Press the AM-FM button to enter the code. The radio will now be unlocked and the display
will change to the clock. Continue with the following steps to deactivate the theft deterrent.
• Press the HR button until display changes 000.

system.
