Turn the key nothing happens :(
 

Hi everyone I've been looking though the forums and havnt found a solution to my problem. Sorry if it's a repeat but I really need help now.


I have an 07 Mazda 3 hatchback with around 77k miles. I drove the car last night with no problems. I came out this morning (not cold) and I unlocked my car with the remote. Get in the car and I turn the key and nothing happens. No lights no accessories no radio. And I also didn't hear a noise.

I checked the fused under the hood and they were all fine.

Came out about 15 minutes later and tried it again and it started without any problems at all. I turned on the AC and there was a weird noise from under the hood that I hadn't heard before but it eventually went away.

Ran a couple errands and starts and runs like nothing ever happened.

I'm also not sure how old the battery is. I do have a small multimeter. If there are things that I should check then please let me know.

Thanks in advance :)
