When I bought my '97 Blazer the Factory installed radio was locked. I had to take it to the dealership to have them plug it into a computer to find the "code".

You could go to and get the code through them. There's a small fee but they seem to be able to get you the unlock code within an hour.

What if your radio stopped working on your 2003 tried another radio but it didnt work either where are the radio fuses or is there some other common problem?

Many radios have an anti theft feature where if power is interrupted like when a new battery is installed the radio will be locked and will not work without an unlock code.The dealer can unlock it for you, and you might be able to find it on the web somewhere but i doubt it.The idea was for you to set the code when you got the car using the instructions in the owners manual, however nobody ever does.Thats why the second unit did not work either.

Changed battery interior light stays on radio not working?

By changing the battery, you erased your car's computer presets. Your car probably has an anti-theft radio, that locks when power is lost to it, and requires a factory security code to unlock it. The code might be in a section of the owner's manual, but if you cannot find it, you have to go to a new car dealership and have them reset the radio.

How does the anti-theft work on a Oldsmobile intrigue 1999?

I assume you are referring to the radio? It has a four-digit security code that the owner can set. When the power to the radio is disconnected, (either because of battery removal/failure, or because the radio was removed) the radio will "lock" and the four-digit security code must be entered again to unlock the radio, before you will be able to use it again. If you do not know the security code, you will need to take the car to a GM dealership, and they will have to unlock it for you.

How do you unlock the radio on a 1994 Jaguar if the radio and CD player won't work after the lights were left on and you had to jump the battery?

It's an anti-theft device used to lock out (disable) the radio in the event that it is stolen. You need the code to unlock it. The code is provided to the owner when purchased and should be with the original paperwork. If you can't find it, you may have to take the car in to a Jaguar dealer and have them unlock it. Good luck. When new Jaguar put the radio code on a sticker on the underside of the hood sometimes these were never removed, so look there for a four digit code
