Default 2004 L300 starts then dies immediately

I’ve been trying for months to get this car back up and running. I’ve replaced many parts ont the car. I know that the engine is not blown and the transmission is strong so I don’t want to get rid of it. I believe the security system is preventing the engine from running, the car starts and dies immediately and the security light blinks. When I turn the car to the own position, the security light isn’t there. It’s only there when I try to start it because of that I’m not able to try the 30 minute key reset procedure. Can anyone help me? I’ll try to attach a video of what I am talking about.

You need to do a security reset three times. I will post the procedure tomorrow. Watching game 4.

You will need to have a battery charger on your battery or jumper cables connected to a running car for this procedure.
