2001 Chevy Blazer: radio system..delco..owners manual..we unlock

This answer was rated:

We have a 2001 Chevy Blazer & we have locked thr radio system (delco am\fm -cd ) & we do not have the owners manual. How do we unlock?

Depends on the type of radio you have.


Some have to be re-programmed through a dealer, others I can help you with.


Does your radio look just like this...

yes it does

Ok, thanks.


You need to pull the two 3-digit codes from the radio.


1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down.

2. After doing step one and writing down the code, immediately press the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over).


Post me the codes after you get them, and I will try to get the unlock code for you.

Your radio code is 0400...


Use the hour and minute buttons to enter this code, then push the AM/FM button, and it should work.
