Today my 2014 Camry started doing some odd things. When I shut the car off and got out it would give me 3 beeps and if I tried to touch the handle to lock it it would give me one long beep. Then this evening when I got home it was doing the same thing but this time once I turned the car off the interior lights came on and faded off then came back on and continued doing this even after I got out of the car. I needed up pulling the negative battery cable off so it wouldn’t kill the battery over night. My only guess is the battery is going bad??? Any thoughts?

i took the battery to be tested this morning and it came back bad. I’m going to put it in this afternoon and hopefully that resolves the issue.
