disconnect the battery and charge it with a battery charger for a few hours then connect back up to the vehicle. disconnect the negative terminal.

a bad battery can cause these issues.

remove the ignition key from vehicle when not being run.

Best to start a new post on your problem.
Things to check.
Did the secutity and battery light problem happen at sme time?
Does it start and run for 2 seconds?
Try a reset on anti theft system.
With a battery charger or jumper on it.
Key on for 10 minutes untill security light goes out.
Then key off few seconds and then repet key on 10 minutes and off and then on two more times.
Then see if it will start and run.
Let us know how it goes.
