How To Start A Hyundai With A USB Cable

Not many people are aware of this but starting a Hyundai car with a USB cable is absolutely possible. It is also easy, as long as you have the right tools for this.

The very first thing to do is to take that plastic cover located behind your steering wheel. You need to get the two screws out to make this happen. Either yank it hard enough or use a screwdriver to pull the cover out.

Once this step is complete, you can then have access to the ignition cylinder and push a little pin in to separate these into two. 

Now, there are a few things you need to use to perform the rest of the steps. 

  • USB plug from your old computer case
  • USB flash drive
  • 2 automotive relays that come with normal open contacts
  • 1 automotive relay with a normal closed and a normal open contact
  • 1 12-volt relay with a normal closed and a normal open contact for electronics

Remove your interior panels to access the wire harness that you use for ignition purposes. When you remove the panels, you need to decide where you will mount the USB plug. You may mount this on your lower panel covering the steering column. 

Now, you need to understand that the length of your wire is a factor when it comes to your placement. This is why you should measure carefully and cut a hole on the location where the plug will be mounted. You need to ensure a clearance from the other vehicle parts once you reinstall your panels. 

It also helps to double-check to establish the correct placement. If you make one wrong decision, you will end up having several holes in your vehicle’s interior panels. This will most certainly not look good.

Also, keep in mind that your interior plastic is quite tough. Thus, cutting it by hand can be very difficult, so you need to be very careful so as not to end up cutting yourself. If you have a hobby knife, then this helps when cutting the hole – but of course, it is completely up to you. 

Once you have the hole cut, you need to dismantle your wire harness. Decide the correct wire color and which one does what for your vehicle. If you have a manual for your vehicle, then that will be very helpful. Remove your ignition’s wire harness and take it apart – be sure not to break this. 

Ignition usually has 4 stages, which is off, on, auxiliary and then start. When your vehicle is off, there is no power at all. The auxiliary is when there is power to your 12-volt power outlets and radio. And when your vehicle’s ignition is in the on stage, it means all components have power.

Then, remove the first portion where you normally insert your key. This means that all you have is a cylinder with a piece of metal exposed. Jam the end part of your USB cable onto this metal piece. Then, turn your USB cable as though it is your key, which should cause your car to start.

Points To Remember

These tips that I just shared with you are important if you find yourself unable to start your vehicle because you have no key with you.

However, you need to keep in mind that other people may be aware of how these steps are done – even if they are not the rightful owner of the vehicle. This is why it is important to realize that it can be both a blessing and a curse that this hack exists.

In fact, just to give you a bit of an idea on what is happening in the United States, Hyundai faces some class action lawsuits because of how easy it is to steal these vehicles by using this technique. 

For instance, theft cases of some Hyundai models ranging from the year 2011 to 2021 have increased rapidly since the release of these instructional videos on social media. There are vehicles that can be quite vulnerable to these hacks such as those that require a conventional mechanical key and are not equipped with engine immobilizers.

This is why as a vehicle owner, it helps to put an extra layer of security to your Hyundai car by purchasing a third-part security kit. However, there is a bit of a drawback since you also need to pay for the installation process. With this in mind, it can be quite expensive to have such security add-ons installed.

Some Hyundai vehicle models without an anti-theft device are at risk of being stolen when unscrupulous individuals try to override the system by using a USB cable. Upon removing the steering column and exposing the key slot, followed by turning the ignition switch with a USB column, they can easily start your vehicle and unlock your steering, which is why it can be quite risky.

Bottom Line

With the relatively easy steps of starting a Hyundai with a USB cable, it becomes prone to theft, which can be quite concerning. This is why it is best to secure your vehicle and make sure you have certain protective layers to it, so you can prevent unauthorized individuals from gaining access to it.
