Hi Elizabeth,

More than likely the alarm system has locked you out. You will need to have the theft module flashed or reset. You do this with a scan tool from a dealer or shop that has one. The reason this is required is so that the dealership or business can confirm you own the vehicle. I attached the procedure in the event you have access to a scan tool.

Unfortunately, once the alarm is activated, it needs to be disarmed but if the battery was drained and removed then more than likely it has just locked you out. Clearly you need to get this evaluated first because if this is your issue then you can replace everything related and it still will not start.

Let me know if you have questions. Thanks

Hello thank you so much for your response. Okay, so my daughter is buying the car from a used car lot. They won't help and they said they don't have this scan tool. We was also informed that we knew the car was used and we are buying it as is. So can you please tell me what type of shop I will need to look for that would be able to scan the module? I wish I could just replace the module. We also bought a fob from Wal-Mart and it didn't work. My daughter lost her job. However if we can just get it fixed, she can find another job. Thank you so much.

Most shops have the ability to do this. Clearly a dealer can do it as well. I would just suggest calling them ahead to make the appointment and tell them what you have. No matter where you go, they are going to do their own diagnosis. Some will replace a module if you tell them to do it but if that is not the cause of the issue then they are going to then charge you to figure it out. So I always tell people to let them confirm what we are talking about, because while I am confident that is the issue, I am not looking at the car and just going by what you are describing. So there is a chance I am not correct.

I am sorry the place you bought it from is not willing to stand behind the car they sold.
