turn the ignition to the on position(don't start) the security light should be flashing. In 10 min the light should be solid, if so the car will now start. If not you will need the tech 2 scanner to clear the security faults

yes the remotes do have batteries. how ever that might be your problem or the remotes lost its code for programing. step when turning alarm off---- if its a factory alarm put the key in the drivers door when the door is closed and lock then unlock it thats the manuel shut down for factory. step 2------- aftermarket alarm. look for a valet switch most likely it would be installed by the driver kick panel or by the under dash fuse box. when u find it put the key into the ignition. turn it to the run position. within 3 seconds press and hold the valet switch for 3 to 5 seconds you should here a confirmation chirp and the led light will stay on solid and wont blink give it a world let me know what happens

A common issues with these key fabs is the solder breaking right where the battery goes in at one of the connections that hold the battery. Do any of the functions work?
