Hi Eileen , How do you know your having a anti-theft system problem ? Any lights flashing when you try to crank the vehicle ? The engine does not crank over ? If it is a anti-theft system problem ,disconnecting the battery is not going to do anything except lose some learned setting's in some control modules . There are a few thing's you can check but if none of these are the problem your going to have to have it towed to the dealer ! It'll need to be checked for DTC'S - diagnostic trouble codes !

Remote can be matched manually

the only safe thing to do is either change code or change remote.

it may be the starter switch is going out.

Often times when you replace the battery in a remote fob you have to sync it to the car by locking and unlocking the drivers door with the key.
Check your owners manual.

Assuming that your car came with factory remote start, simply go to the Driver Information Center (aka radio) and with the key to on position, press the information button until you see the option for remote start. When you do, and it says OFF, press the Enter button to change it to ON. Shut the key off try your FOB (press and release the Lock button and then press and hold the Start button (top of FOB) until it starts (1-2 seconds). If the lights simply flash instead of starting the car, you either did not set the 'radio' right or you have a more serious problem.

There is no onboard programming procedure for this vehicle. This vehicle requires special equipment be connected to the vehicle to program the keyless remote. SEE THE DEALER.
