My friend has a 2004 Dodge Stratus and it will not start. Instead, there is an annoying clicking or tapping noise when the key is turned. Is that a problem with the alternator or battery?

Possible starter motor problem. Try tapping the starter motor with something as you turn the key to the crank position. If it starts or makes any noises, suspect a starter. If no help, you will have to check for start power directly at the starter solenoid and diagnose from there

Check Battery , battery connections are tight an no corrosion ! How old is you Battery ?

It sounds like the battery is about dead or starter is sticking I'd check battery first if that doesn't work tap on start then tr to start

I know you want cheapest way to start my dodge did the same but I was able to get it started by clicking key 2-3 times by holding key in the start position and rapidly turning key , if it starts it not the relay its the starter selonoid in the starter (non replaceable)

quick test, have someone tap the starter while you hold the key to start, if it turns over you need a new starter.

It sounds like a serious engine failure has occurred you need this sound listened to by an expert.

By looking for another engine or Vehicle.

had the same problem with a 99 dodge van. tow truck driver put the key into the ignition and tapped it a couple of times while turning the key to freed it up and start the engine. works as long as you leave the key in the ignition so i use a second key to lock/unlock the van. hope this works for you. gary

Hello
Check the battery cables and battery before replacing the battery
starter is located down by the oil pan on the engine on the radiator side

if you tap on the lock cylinder with a small hammer it may jar it enough to get it to turn.....to replace the tumblers you will need to remove the lock cylinder and then disassemble it. each tumbler has a certain number on it and will need replaced with that same number. it is easier to have it dealer or locksmith do it.
