Jeep commander clicks once and won't start. It is

The broken metal part needs the transponder to work , jeeps come with two keys you should have another set .

starter soilinoid defective ????

it wont crank, no A/t car starts unless cranked first. (a key point)

fix head lights first. this is a feature in all cars.

that is SIMPLE and HOT all the time

they must work at all times and is the top way to diagnose

electric problems



you have a dead battery,.

only why remains.

i bet it cranks jumper cable started, call AAA or buy some cables.

or swap in a charged battery , or heck charge yours, buy a charger.

check fuses.

check battery lugs for green death?

check battery voltage. at 12.6vdc, if not charge the battery

if the battery continues to disgharge.

that is called phantom drains, or bad battery .

or the alternators is bad.(system)

once started the battery volts must be 13.3.to 15v, if not the charge system is bad ,(fuses, belts slipping and lots more possibles)

With a voltage meter see how many volts are at the starter terminal. If not 12+ volts you have a bad connection. Check connection at the starter solenoid. Does it have 12+volts? Short the solenoid. Does it put voltage to the starter?

Any clicking noises? My first thought is lithe starter has failed. Typically if all the other accessories are working and the starter doesn't when you turn the key it's likely the starter. Usually an a single click is heard everytime you turn the key to the start position. If you heard a series of rapid clicks when you try to start you likely have a weak battery. A jump start may get you going.

Check your alternator by starting engine and removing negative battery cable while running. If engine stops, replace alternator.

The voltmeter should only go as high as 14-15 volts when the engine is running. I would check for a poor connection between the battery and starter.

I have had this issue 2 times, both times it was the battery having damaged/dead cells. You can sometimes get it to start by putting your foot on the break, turning the key to the on position, putting the car in neutral then starting it. I purchased my Commander new in 2006 and have had to replace the battery 2 times since, both times this was the initial symptom. I have 120K miles and still love my Commander

First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.
