I have a 2012 Jeep Compass when key is in the ignition everything is fine all the lights are fine tested the battery that’s ok when you go to crank it makes one click than nothing if you know what it is lmk
Will it start with jumper cables or a booster? That would indicate a dead battery. IMHO that's most likely.
Also consider your battery cables. They may be capable of powering your lights and other accessories, but the starter pulls a lot more juice. If the cables are corroded they won't carry as much current and it will act like a dead battery.
