hello everyone im new to this forum,please help.
i change battry on my cts,what i did was stupid

,i got a battry with side poles and poles on top,cut off the poles on top,didn't put any kind of protection because i didn't know better,drove the car for weeks no problem.

1 day it stopped with me while driving,and a messge came up on the display starting disable remove key,when i checked under the hood i saw where it had a little burn under the hood,i changed it to the right baattry,the only way i get the car to start is turning on the key for 10 mins 3 times,but i notice the car sometimes shut off after been driven a while, oh and sometimes it reads on the display 0% engine oil,0% transmission oil,since this had happen,
can anyone help me?

Do you have the correct battery in there now? I'd recommend the OEM battery or a battery that has 800 cca or more.

Try removing the cables for ten min and reconnect. Reset your oil indicator by holding it down for ten seconds. You may have to reprogram the auto up windows( down then up, hold the switch up for three extra seconds)

Jemile, definately get a different battery in there if it's making burn marks. As to the turning off while driving, how fast are you driving when this occurs? If it turns off and you keep it in gear while driving on the highway, does it restart itself at all? Mine used to turn off for a split second only while on the highway, but would restart itself if I left it in gear, and the same message would appear. I didn't really look into it further because it seemed to have stopped... What year is your car? You may be able to find a trouble code or two in your car's computer without having to go to a dealer or autoparts store (let us know if you need help with getting the codes). Also, try typing in "starting disabled remove key" in the search box of this forum and see if you find anything, and keep us posted.

If the ECM is replaced it has to be programmed with the proper calibrations, also the VTD (theft) password must be learned between the ECM and the VTD module.
The Passkey module sends a coded password to the ECM for fuel continue. If the ECM is not programmed to recognize the coded password it will go into theft mode and shut the engine off.
You will just have to get the car to a dealer and have them to the SPS and VTD programming procedures.

I am not sure that a battery condition like that would cause all this but... who knows?

ewill3rd...what if you disconnected the battery, then disconnected the ECM and then reconnected the battery to do something else, after you did that the anti-theft comes on and you get nothing? then you put it all back together, would you need to have the ECM reprogrammed/relearned? i think this somewhat of the issue i am currently having...thanks for any and all help you can provide...

OP...sorry for the thread jack...

the ecm did come programmed, had a mechanic put a comp. on it and it said lost communication pcm.

Jemile, I am confused, what is the current status of the car?

txbest, once the password has been learned both modules will retain memory for fuel enable and continue even after loss of power.
You can take the ECM out and put it back in and also the VTD module with no effect.
It will give you a fault message when you restart after a power loss but on the next ignition cycle it will be fine.

sorry if i confused you,when i turn the ignition on starting disable remove key appears and the anti theft light.when you try to start you get nothing.

It sounds like you are saying that the ECM is programmed with the necessary calibrations, but it still has to be programmed with a separate programming for the theft system.
There are two programming events that must take place.
One to install the software and VIN for your specific vehicle, the other to match the ECM and VTD passwords.
If this has not been done the car will never start.
