RDS theftlock Gm radio 2002 blazer?

Question

i have no idea whats going on but my blazers battery died last night and i charged the battery now my radio wont work.. the crazy thing is that its not the theftlock)) because its a RDS theftlock radio which im told is the type that runs off the vehicles vin number..... but this radio has been in my blazer forever and always worked.....this also means that there is no code to put in.... you cant hold 2 and 3 down or 1 and 4.... so how am i supposed to get it to work???

Answer 1

If it doesn't say "lock" or "safe" on the display, then Theftlock isn't causing the problem. I'd start by checking all your fuses.

Answer 2

I just looked in the manual (https://www.mygmlink.com/main/US/en/gm/intlink?inturl=/pdf/go2content/manual/US/en/chevrolet/2002blazer.pdf)
for it & it agrees with what you say - learns a part of the vin number, but doesn't give a "what if" scenario when that system doesn't work after a battery failure.

I'd say call your local GM dealer, unless someone else answers who is a car audio owner / tech.
