The car will no longer unlock with the unlock keys and the two keys that were given that are actual keys when inserted will not work. Also, when we were able to enter the vehicle, we couldnt start the car, im thinking its a security issue or ignition issue/starter. please help.

We've checked all of the fuses, but we are unable to even get into the car is there any way to check underneath the hood for the anti theft or maybe even disable it?

If you can get underneath the hood-check the battery available voltage could be low not supplying enough power to activate the anti theft system-If it continue-you gonna need the dealership

Well it as been broken down for quite some time now, the battery should be okay, if that IS the issue, is there any way to temporarily disable the anti theft system? We also cannot get underneath the hood to check due to it being locked im nearly positive. Tricky situation i know..
