Hi

I have the exact same problem as you do with my 2004 optra and it happened just over 3 weeks ago.

How have you made out? I have to disconnect the battery and I'm going to try and call chevrolet if I can find the answer

I have this problem right now too. You were soposed the get a card with the purchase of your vehicle with the security code on it. I bought mine used and did not know I needed it and come to find out I never got it. The only thing that can be done is to take it to a dealership where they will get numbers off your radio an vin on your car to get you a new code or replacement card. If your dealeship is like mine it will cost about 37.50 as a basic diognostics. Don't try to press random numbers. There are hundreds of thousands of combos.

what code do i use for a chevrolet optra 2004 radio code to unlock it

i want to buy a new engine for my car 2004 chevrolet optra LT can you hepl me

Optra 5 2004 ls code 3241 worked for me . thankyou verymuch u guys saved me my time and money

found out there is a 10 amp fuse on the back of the radio itself,replaced it and all is well

Check your fuse more then likely it blew. Car radio Clock and Cigarette lighter all connected to the same fuse.

I have a similar problem with my 2005 Optra 5 - daytime running lights are hit/miss. About 3-4 years ago, the alarm started activating itself - FREQUENTLY. Turns out it was corroded wires. Now this. (Take heart - my Corolla had a similar problem - bad sockets - bulbs burned out faster than they could be replaced. Toyota never did admit responsibility.)
