Car has no power absolutely opened the door with the key tried starting the car no sound no light now key is stuck in

try the main fuse coming from battery to fuse box under the hood sounds like it popped.

To arm content theft alarm.
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The
SECURITY light should flash.
3. Close all doors. The SECURITY light should go off
after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.

If a locked door is opened without the key or the remote keyless entry transmitter, the alarm will go off. The headlamps and parking lamps will flash for two minutes, and the horn will sound for 30 seconds, then will turn off to save the battery power.

Hi there all the things you explain are and need power to operate, make sure your battery has 12.6 volts or more and try again , if your battery doesn't have that voltage then you will need a new battery, hope this helps

Try pushing in on the inside door handle while you try opening from the outside with your key. Sounds like you have a lock rod inside the door hanging up the operation you are trying to do or someone tried slim jiming your car

try this it may work put key in ignition and turn to number 2 ( lights on dash) press the fob button on the key. doors should lock, then turn back off to 0, then press the fob button again the doors should open then try to start engine. if all works again but the alarm keeps going off randomly, the power sounder battery may be flat, it can be charged when the system is working again. but sometimes it can get damaged. and it may need to be changed. as I dont know what the sound is coming from under you hood Im thinking it could be this.

You should have power to the dash if the key switch is working.
The main fuse would kill everything in the car.
Depending on how it happened, I would check the fuses and then check for voltage at the key switch.

If you need to be that close to the car to start , you still have a bad to low battery.,You notice that you had to get close to it.If you are sure absolutly have a new battery enter the car put key in regular position leave key in for 2 minutes cylce it off there see if it will start back in it normal range.

Probably your security system or the safety interlock. If the security light is not on, try giggling the shifter or starting in neutral.

Please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Sounds like the timing belt.

that acts like the starter solenoid has a bad connection or has gone bad. first remove the starter , and see if there is any corrosion or burnt areas . also while you have it out , take it to auto zone . they will be able to test it for you for free .
