Yes I have a listing of the codes. Which one/s do you need a description for?
I put your question back in. Please do not reply to this message.
I'm not sure what exactly you need so please be as specific as possible.
Why did you replace the battery?
What is wrong with the car now?
What "codes" do you need?
Why do you think the car won't start.....does it crank but not start....do you turn the key and nothing happens?
Does everything else electrical work?
I will do my best to assist and sorry for the delay!
It sounds like you may have accidentally set a code for the start inhibiter. When you turn the key on does it ask you for a code? If it does enter the code you think you may have entered. Maybe you set the radio code for the start inhibiter. Try that. If that doesn't work let me know. There is a reset procedure for the start code but i will have to look it up as i don't remeber it off the top of my head.
If you remember what you may have set the code to try it. If it doesn't work let me know and i will look up the reset procedure.
If you don't know the correct code to start the car the reset procedure above will have to be performed.
Now i'm somewhat confused to. The only time you should have to enter a code for the radio is after you disconnect the battery. Then you shouldn't ever have to enter a code for the radio again unless it looses power.
Are you sure your not re-entering a start disable code? When the car doesn't start does it ask for a code?
Another note...the radio code should be input with the number buttons and the start disabling code I belive is input using the 1000,100,10,1 buttons.
From what I remember after performing the emergency reset you should no longer need a code unless you put another one in.
After you unhook the battery,reconnect it and the 15 min countdown is over the car starts? If so be specific on what happens to cause it no start again. Does it ask for a code when it doesn't start ?
Let me know.
Definitely give that i try first....if the reason the car won't start is do to a starter disabling code that procedure should delete it. Remeber not do get confused with the radio code. I would not worry about entering the radio code untill you are confident the car will start every time, and that any starter disabling code has been deleted. This way there is no confusion as to wich code is being asked for.....the only thing i can think of is the car is asking if you want to enter a disabling code and when you enter what you think is the radio code you actually activate the start disable feature.
I should of explained this before in case you don't fully understand the feature:
The starter disable code feature is designed for extra theft protection. For instance if you have children that have access to your keys but you don't want them to be able to drive the car you can enter a code that only you know. Once you have done that it activates this feature. Now the only way to start the car is to remember the code and enter it before you can start it. There is no universal code that is specific to your car,(like the radio code), the starter disable code is a code you make up on your own and enter it in to prevent people that don't know the code from driving your car.
Once the reset procedure is performed correctly you should never have to enter a code to get the car to start. If you go to the code function screen for the starter,(not the radio), and enter a code you may have just activated it...and now the car won't start unless you re-enter it again.
For instance if you enter the radio code in the starter code spot you may be accidentally activated the start disable feature.
Hope this helps!
