Hazard lights? Any interior lights?

No power inside or outThe battery test and is good
Automotive Expert
The battery could have a dead short. Do you have access to a multimeter?
Automotive Expert
We need to verify we are getting power to the fuse box first. Test for battery voltage at the fuse box post (the bolt at the end of the long white fuse box link).

Sorry the locksmith needed meI have a battery tester I have a battery maintainer I have jumper box just a little guy and cricut tester is all I could find
Automotive Expert
Okay we can do some basic things with a test light. 1. Make sure that both battery terminals are tight 2. Connect the test light to the negative battery terminal and touch the post inside the fuse box (test light should light up) 3. Connect the test light to the positive battery terminal and touch the engine block (test light should light up) Let me know what you find.

Perfect, use the 12v tester and perform the tests above. The aligator clip on the end of the wire attaches to the battery terminals as listed, the probe touches the pieces listed as touching. 1. Make sure that both battery terminals are tight 2. Connect the alligator clip on the test light to the negative battery terminal and touch the probe to the bolt on inside the fuse box (test light should light up) 3. Connect the alligator clip on the test light to the positive battery terminal and touch the probe to the engine block (test light should light up)

Sorry governor me a sec please
