If security light goes out then it's not the key. You have some other issues.

I would start by checking fuses. I would also retrace my steps and see if there was anything else I touched. Also even though that immobilizer light is turning off I would probably unlock the drivers door with the key from outside. If none of that works do the basics. Check for fuel and spark

Unlocking the door from the outside is another way to turn off the alarm. So where is the key that is for that door?

I have it here will that new key not being able to unlock the door prevent the car from starting no alarm is going off .I'm not getting anything the starter is not turning the engine all I get is a faint clink sound again it s not a weak battery I've seen the videos were the key had to be programed and they all got the starter to turn. On my car does the starter turn even if the key is not programmed correctly

The key does not need programming especially when security light goes out after you insert the key.
If you're only getting a click and battery is good then I would be looking at the possibility of a faulty starter.
Just to be sure, jump the battery with another car and see if anything changes.
