Hello Vickie,

It sounds like your battery is dead, or if you're really lucky, your battery cables are corroded.
Pop your hood and inspect your cables at the battery, especially the Positive (Red) lead. If you see white oxidation build up, then the cables need to be removed and cleaned.
If clean, then the battery may be dead. It can be beyond its service life (sometimes there is a date code on the battery so you can determine age).
If the vehicle can be jump started; after starting, turn on heater fan and headlamps to high. If the lights are dim, then the alternator may be bad or is going bad.
Start with the battery first, then go from there.

ANTI-THEFT SYSTEM Passive anti-theft system
Your ignition key has a unique imbedded transponder which engages engine electronics and allows the vehicle to be started. Without the use of your special ignition key, the vehicle will not start.

During each vehicle start, the coded key is read by the anti-theft system. If the key’s ID code matches the code in the anti-theft system, the vehicle is enabled to start.

You may have a faulty ingition. Otherwise you have the very common GM anti-theft system. If you have a flashing anti-theft light with key in igniton, then this is what you should do:

Put key in ignition, turn to ON position (Do NOT Start)
Leave in on position for EXACTLY 10 Minutes
Then while watching the anti-theft light, as SOON as the light turns off after 10 minutes, START CAR IMMEDIATELY after light turns off.

This will reset the anti-theft

make sure you have a fully charged battery turn on the ignition with out starting the vehicle let sit in on position for 10 to 15 minute then start it may take a few attempts
