There is a problem with the theft system. This is the system that pervents the car from starting if the ignition lock cylinder is damaged when someone trys to steal the car.
You can try and do a relearn, it may let the car start after this relearn. The most common cause for this concern is the ignition lock cylinder, it has a computer sensor inside that goes bad, you have to replace the cylinder and program it.
To reprogram/relearn, put on the parking brake(this will keep the headlights from comming on and draining the battery), try to start the car, leave the key in the "on" position. The security light should no be flashing. Wait for tem mins, the light should turn off. At this time, turn the key off for 2 seconds and try to restart. At this point, the car may start, if not let the key stay in the "on" position again for tem mins untill the light turns off. Again turn the key off and try to start the car. It may take 3 times for the system to relearn, if you try 3 times and still no start, you will have to replace the ignition lock cylinder.

Security light goes on and off when sentra is not running

The blinking light doesnt mean that u have a security system it means that Nissan immobilization system (not an security alarm system) is working, which i believes comes standard on all new nissan cars now. but this feature prevents someone starting the car without a nissan key, because our keys have a microchip in it which the car can read. and if a key that doesn't have the right chip in it is used it wont turn on.

Check in your owners manual the right disarm procedure.

That means the factory security is not arming, not being set. ( i.e. a door is not completely closed or the trunk/door lock has been vandalized ) It could be for other reasons but first check the obvious
