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.

Here are some helpful articles:

Thank you.

Hello

no I have not tried to jump start my car yet.

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

I tested the battery using a multimeter and it was at 5.6 but that's only because I haven't drove or started it for 2 weeks maybe more. I'm starting to think it's one of my electrical components.

Because I can't turn on my headlight or none of my electrical components seems to be working at all. I use my spare keys and it seems weak then not working. Ugh.

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.

Hey, so when I jump started the car it works fine. everything was working properly, but the next day when I tried to start it again everything shut off?

Is that a sign I have a bad battery? Alternator? Or parasitic drain or a bad ground wire somewhere?

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:

Let me know what you find.

Hey, I tried to jumpstart my car again and my light and horn went on (flashing)? Please help.

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

Oh, but I read some post and some people say that using the key should stop it?

What would happen if I did reset my 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.

All right. So, I just have to lock it and unlock it and it should be fine? Can I use the key button's function, or do I have to insert the key in the door?

Was checking out my battery and noticed this. I don't know if it is new or it was always there.

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.

Key fob button didn't work and didn't try turning on ignition didn't want to ruin it anymore. There was some electric spark or something when connecting the jumper cable (I forgot if it was the positive or negative cable that did it).

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?

Hey, changed my battery and now it works fine now. (:

That is good news. Let me know if something comes up.

I want to install a dashcam for the front and back but my only concern is if it will affect the warranty (I have it for almost 3 years) the dashcam requires me to swap out the interior rear-view panel with a new one?

Ever since my accident I been wanting too. Would you consider that a modification?

The camera I want to install.

As long this is a plug and play and you are not splicing wiring, this should not affect warranty.

All right. Thanks.

You are welcome.

I notice that my car gas cap cover isn't working when I push on the button? Is there a fuse or repay for it ?

Since this is a new issue, can you please open a new thread? As it can help anyone who might have the same issue.

This will also put it in front of all the experts.
