To start off, I replaced an old battery 2 weeks ago with a brand new one. It was fully charged and worked perfect for those 2 weeks. I wake up one morning to find out my car won't start. No "one" click, nothing. Sometimes if you hold the key to start the car it will have a faint fast clicking that vibrates the key some. I checked all fuses, I charged the battery over night to see if it was an alternator problem but then come morning, nothing the same as before! Jumping it didn't work and the connector cables are clean and fine. My dad thinks it could possibly be an anti-theft issue or a key issue if someone tried to break in. Please any help would be great need it for school and work. Thanks.
