Unlock code for my car stereo please HELP!!?

• so my husband got a car out of the auction and since it was a little crashed he took it for maintenance and stuff at a body shop they took out the car battery and now the car stereo is on lock mode and there's a flashing light that says "security" the car is a 99 cadillac catera and i called a cadillac dealer and they said they can unlock the stereo with a code but its $120!!!! does anyone know a alternative???? does anyone HAPPEN to know the code for this!! please please please help. i've been searching the internet and i found nothing!!! THANK YOU!

• Answer:

  We will not know the code. The code is not universal, meaning there isn't one code for all the cadillac cateras. Each one has a different code. I obviously suspect that the car did not come with the original owner's manual, which may contain such information. Also, I hope you have the best of luck with that car, but Cadillac Cateras are one of the worst cars ever made. in those years, cadillac wanted to use a V6 engine but get the power of a V8 so they went to the Germans for help. The end result was an extremely unreliable car with very costly repairs. It even has a timing belt, which if breaks, will ruin the whole engine. So be sure to check up on that as well as it may need replacement. I hope it is not a 1997 model. Those were the worst. There is your first repair bill---$120 for a radio code, though I would buy a new pioneer CD player from walmart for less than $100 and install it myself and do away with the code!
