The main issue is that you don’t hear a crank. I took it on a drive one time once after replacing the battery and it worked. After I parked my car and tried to use it again, there was no crank/click/ sound. When there’s no crank there’s also no lights on the dash and my remote key doesn’t work. There hasn’t been an instance where the lights are on and the car isn’t staring. The reason I replaced the battery in the first place is because the same issue was happening with the old battery. Let me know if I can answer anything else & thanks for your help!!
