My car wont start at all and no lights comes on

Hello,

Just so we cover all the possibility.
Have you tried to jump start the car?
It could just be a dead battery. As you do not have any lights coming on the dashboard, that typically points to a bad battery.

If you are able to jump start it and it runs fine that it is the battery that is at fault.

Let me know what you find out.
Thank you.

The symptoms you mentioned sounds like a dead battery.
If the battery is bad, you will be able to jump start it.

You could have excessive amount of parasitic draw (current drain) on the battery.
Every circuit will have some amount of draw but it can become excessive due to a issue with a electrical component.

Here is a guide of how to find the parasitic draw:

Let me know if you have any questions.
Thanks.

It can be that you have a bad battery. Parasitic drain is another possibility.
But it does not seem to be the alternator. If it was the alternator then the car would not stay running after the jump start. Remember a car will run with a jump start just fine, even with a bad battery. It's just you won't be able to restart it after shut off.
I think next best step would be to get the battery tested. You can do a load test on your own or take it to your local auto parts store and they can use their machine to do the load test (more accurate).

Follow this guideline to do load test on your own:

It sounds like the anti theft got triggered. Disconnect the negative battery cable and wait for about a minute. That should reset the system.

Yes, you can stop it with the key. That is the proffered way. Only time you want to unplug the battery if your key fob is missing or not functional.

The battery cable is normal. I don't know why Toyota does not put an insulation on the wire at that connector.
Any time the alarm goes off you should be able to turn it off by pressing the lock and unlock button on the key fob. If that does not work, then you will have to put the key in the ignition and turn to on position.

Got it. So as of now, what are you experiencing? Still not start?
Is your security light staying on?
Or were you able to jump start it?
