Problems With Push-Button Start Cars? (4 Main Issues)

Push button start cars offer easier access to starting and stopping a car. With a smart key fob in hand or in close range, your vehicle will start as you press the start button while your right leg holds down the brake.

Sounds cool, right? Well, if you’re thinking of upgrading your car to this keyless level, you need to learn about the downsides of the push-button start technology.

We’ve not only uncovered the common issues with these cars, we also provide proven solutions to them.

Here are 4 most common problems with a push button start car.

1. Engine won’t start

Normally, you start a keyless car by pushing the ignition button in while pressing the brake. But, sometimes, the car would refuse to start even when you’ve done the right thing.

When this happens, you may get a message on the screen reading “Key not detected” as you push the start button.

The truth is, this is a common but minor problem that you can easily fix. Here are 3 simple ways to solve the key not detected problem.

a. Check the battery of the key fob

Your engine will refuse to start when it fails to read a signal from your smart key. This happens when the battery of the key is low or damaged.

So, replace the low or spoilt battery if you have a replacement and restart your car.

b. Push the button with the key

You can also start the car by using the smart key to push the start button.

Just push the button with the rear side of the key while you press down the brake, and the engine will respond. This works on many Toyota vehicles and some other brands.

c. Use your smart key like a traditional key

Sometimes, the engine would refuse to start even when there’s no fault with the smart key.

When this happens, try to push out the cover of the start button; insert your smart key in the hole, if suitable; and start the car the same way you would start a key-to-start vehicle.

While this option may not work for all vehicles, it works for many Mercedes Benz models and some other cars. If this works for your car, you still need the attention of a professional to check and fix the problem.

If you drive a Honda car that features the push-start button, you may need to press the ignition button up to three times or more before it responds. Many Honda owners, especially the 2016 HRV, have claimed that this works for them.

If you have this problem with your Honda vehicle, you may need to clean the push button module. Seek professional help if the problem persists.

2. Engine does not turn off

Sometimes, you’ll notice your vehicle system clashing on whether it is in park mode or not. While a sign indicates you’re in park, the other states otherwise.

Well, this is a system error which can frustrate owners of keyless cars. This is because the engine of the car won’t stop when you press the button.

You’ll only switch off the engine by placing your car in park before pressing the button.

So, what do you do? Check the gear shifter of your car. Look out for a broken cable or a mis-aligned part. If you can’t fix this yourself, call a professional.

3. The smart key fob can be hacked

Have you thought of how the keyless remote works?

The smart key amplifies the signal that comes out of the fob. With a wavelength of about 3-500 ft, the vehicle can read the signal encoded in the key from a significant distance.

While the smart key is active, there is a constant communication with your vehicle and other nearby receivers.

Is there any problem with this? Of course, yes. This constant communication can make your car vulnerable to theft.

The smart key of every push-button start car houses the digital code responsible for accessing your car. Being a digitally encoded keyless remote, this device can be hacked by professional thieves, thereby granting unauthorized access to your car.

Wondering how possible that is?

It takes a hacker to read the signal of your remote if found within range. Once the hacker reads the code, it can be transferred to another key fob which can be used to access your car.

So, how do you avoid this?

Unknown to many owners of push-button start vehicles, you can simply deactivate the keyless remote when you’re out of your car. By pressing just two buttons, you will prevent your car from possible external accessibility.

Doing this will also help manage the battery of the smart key.

Learn how to temporarily deactivate the key fob through the steps below:

  • Hold the key fob firmly.
  • Hold down the lock button for about 2-5 seconds.
  • Then press the unlock button twice.
  • You’ll notice a red light pop up on the fob. This indicates that you’ve temporarily deactivated the remote signal of your car.
  • Once you’re ready to access the vehicle again, just press the unlock button and the car will let you in.

Note: Please check your owner’s manual for the specific instructions for deactivating your smart key.

4. It could lead to environmental hazard

If your car features the push button technology and it is very noiseless, you may leave the engine on thinking you’ve switched it off.

This could likely happen if you’re new to the technology or you leave your car in a rush. Remember that many factors, listed above, could lead to a failure of the push button. So, you should always ensure your car is off before leaving the cabin.

When you leave your engine running, it’s just a matter of minutes before your surroundings become engulfed with carbon monoxide caused by the emission from your car’s muffler.

You know how dangerous this situation could be, right? So, be mindful of the state of your engine when stopping your car.

If you use some models of Ford, Honda, Toyota, Nissan, Hyundai, Mazda, GM, you’ll be less likely to have this issue. This is because some of these cars feature an audible alarm that could chirp or chime to alert you that it is still on.

However, if you use a Chrysler, Mercedes-Benz, Volvo, or Volkswagen, which all have no audible alarm, you should be very mindful of the state of the engine when stopping the car.
