My car has 49000 miles.
My car has an automatic transmission.

You may have a bad switch for the theft system in the left door and did not turn off the theft system when you turned the key. Try to get out and lock the doors. Then turn the lock to unlock the vehicle again to see if the theft system turns off. Put key in ignition and turn key on and see if theft light stays on. If it does then you will need to have another key made and programmed to work with your theft system.
