Push button start car wont start

Your car start button is a convenience that means you can leave your key or fob in your pocket and fire up the ignition as quickly as possible once you’ve slid into the driver’s seat. Like all modern automobile features, however, there’s a chance that one day you might push that button and have nothing happen.

Here’s what you should do next.

1. Hold the Key up to the Button

Most car start button systems work by way of a technology called near-field communications, or NFC for short. As the name suggests, near-field requires that the key be positioned close to the receiver in the steering column in order for it to work properly. In some designs, a dead battery in the fob can prevent the vehicle from starting if the key is in your pocket. However, if you hold it directly against the button, the signal is often strong enough at that short distance to make a connection with the key and get the ignition running. Then, you can go out and buy a new battery or find a fresh fob at the dealership.

2. Charge the Fob

Some vehicles — such as BMWs — feature a small nook in the dashboard or the center console that is the perfect size for storing the key. These cubbies also double as charge points, which means you can leave the fob inside of them to recharge the battery should it no longer be functional. In addition, some newer cars even add a USB connection to allow them to be recharged inside the house.

3. Open up the Fob and Find the Hidden Key

A mechanical backup is never a bad thing, and there are a number of automakers that provide a physical key inside the remote fob that can be popped out and used to start the car’s battery in an emergency. On some vehicles, you can pop off the car start button to reveal a key slot underneath, while others conceal the key slot under a round panel on the steering column, where you would traditionally find it. Check your vehicle manual for details on where to find your mechanical key slot.

4. Call Support

If your vehicle has a customer support line, most of the time the operator will be able to help you start your car, so you can bring it to a dealer and have the key fob or car start button serviced. You will most likely have to be near the vehicle when you make the call, and be willing to confirm your identity and ownership.

Don’t let a bad push-button start ruin your day. Follow these steps and you’ll go from stranded to on the road in no time.

Having been bitten by the car bug at a young age, I spent my formative years surrounded by Studebakers at car shows across Quebec and the northeastern United States. Over ten years of racing, restoring, and obsessing over automobiles lead me to balance science writing and automotive journalism full time.  I currently contribute as an editor to several online and print automotive publications, and I also write and consult for the pharmaceutical and medical device industry.

2010 nissan altima 4 cyl, automatic, CVT, push button start. Makes attempt to crank, will not turn over. Eventually will start, but big problem for us. Not the battery, just replaced that. Lights, windows, radio all work, however, the drivers power window will not go up with one touch, only down, not sure if that matters, but that just started as well. How would I tell if it was the alternator versus the starter? Big storm coming Thursday and my husband has a 7 hour window tomorrow in which he can get this done. not sure what else it can be.

Hi there. Even a push start button vehicle can be jump started; it’s done the same as any other vehicle with the exception of a hybrid. More than likely, you have a failed battery. I recommend the use of portable lithium ion jump packs for jump starting. These packs provide enough amperage to jump start most vehicles today and have a built in protection circuit in case you hook it up incorrectly. They also help prevent against electrical overload and usually will not cause any issues with the electrical system. If your alternator has failed, then jumping the battery will not help as the alternator is needed to maintain the charge of the battery. I suggest having a qualified technician perform an inspection to avoid any additional concerns and avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a car does not start inspection.

How do you start a push button car with a dead battery?

Use the key fob to push the START button. Instead of using your finger as you normally would, press the key fob against the button. This is a backup system many manufacturers use to ensure the car can start even when the fob is dead. In some vehicles, you can start the engine with a hidden key fob slot.

How do I reset my push start car?

Insert your ignition key and turn it to Accessory (or press the start button once without pushing the brake pedal). Press the Lock button on your remote car starter. Within five seconds of turning it on, turn your key back to the "off" position (or press the start button again).
