You cannot. You need to change the battery in the key FOB. The Key FOB is plastic and can be pried open to get the old battery out. They cost a couple of bucks, and you are back in business. The anti- theft security system will not allow you to manually do anything. You need the electronic code to be transmitting to disarm it and allow the ignition to work. You need another battery for your key anyway, so don't waste any time... just change it out.

The above answer is incorrect. You can start the car with a dead key fob battery. From the owners guide: page 11(ish)...the following is buried: NOTE: In case the ignition switch does not change with the push of a button, the RKE transmitter (Key Fob) may have a low or dead battery. In this situation a back up method can be used to operate the ignition switch. Put the nose side of the Key Fob against the ENGINE START/STOP button and push to operate the ignition switch.

If you accept a Chrysler rental car with a push button start, be prepared to have to use the nose end push method when the key fob won't work. You will have to push really hard and probably multiple times before the car will start. If you get out of the car before starts, the alarm system will activate so be prepared for folks at the roadside park and the restaurant [next day] to be annoyed and glare at you that the horn is honking and you can't shut it off. I will not be accepting a Chrysler push button again.

@Retta use the key that is located in the back of the key fob. On your driver door handle is a key hole.

I just bought a 2014 Chrysler 300 with the keyless entry and the fob that has the hidden key in the fob. Can someone tell me what the key is actually used for please. The only thing I can figure is that you can open the door with it, and then use the nose end of the key fob to start the car, whether the fob's battery is in good working condition or not to then start the car by pressing the fob up against the start button. So is the actual back up ONLY good if the fob's battery is dead so that you can get into the car to then use the key fob to start the car ??? Does it have any other use ??? Someone stated that you can possibly pop off the front of the start button and there will be a key hole to stick the key in to start the car...Is that correct ??? I've never tried it. Any help is appreciated.........Thanks !!

I have a 2012 Cadillac SRX. I Just lost the key fob, but have the key. My other fob fell in some water and doesn't work. Can I start the car manually with just my key?

Jetlounge you are the best. You just saved my bf he was about to have a panic attack thats a bilion.


The negative to all this is that car thieves can do the same if they have any dying fob it will let them start your car. I had a 2016 Sentra and I was unloading laundry from my car, doors unlocked but fob was in my posession in the house, they drove the car away in the 2 mins I was in my house.

Is there anyway to start the car without the key fob at all? My husband took my keys to work this morning by mistake and he's two hours away. I have a spare key but don't think it means anything except that I can get stuff out of my car right.

We have a 2014 Dodge Durango. The key fob "not found" message came up on the dashboard. The first time we pushed start with the end of the key fob it worked. Immediately after that no luck. We unplugged the battery (located under front passenger seat) and then plugged it back in for a reboot and it worked.


I have a 2009 Chrysler and here isn't a push button, due to leave on my holiday half an hour ago Any help would be great
