How to Fix a Problem With Your Hyundai i20 Key Fob

Battery

Hyundai has developed a smart key fob that is able to perform various remote functions, like locking and unlocking your doors, launching your car and even triggering the panic button.

There are several things you can do in the event that your Hyundai i20's primary fob isn't working properly.

The first thing to do is check the battery. The majority of smart key fobs utilize an internal battery that can be replaced in a matter of minutes. This is usually the quickest and most affordable method to fix the problem. Replacement batteries are available in the majority of stores or on the internet. After you have put the new battery and you have it open, check to ensure that the battery is in the correct place and that it's in contact with all of the connections.

Make sure to take a photo or make note of how the old battery was placed on the circuit board prior to removing it. This will enable you to replace the battery the same way. The majority of Hyundai smart key fobs are powered by the CR2032 battery, which is available in most shops and on the internet. Once you have the battery in place, close up your key fob and test it to determine if it's functioning again.

Contacts

If your Hyundai key fob suddenly stopped working and you did not drop it, there might be a problem with the internal chip. The receiver module inside the car utilizes radio frequency signals to communicate with the remote. If these signals are obstructed by nearby transmitters or objects the key fob could stop working properly.

Think about the Hyundai Digital key system if you're looking to lock, unlock and start your vehicle on your way to work in Reno.

First, take a note of how the old battery is placed on the circuit board or take a photograph. This will help you place the new battery in the same spot.

Water Damage

The rubber seals on the key fob shield the chip from water. So, if it survives the splash of water from a washer or even a brief immersion in light rain, it's unlikely to get damaged. If you've dropped it into the pool or ocean then the water could get into the seals and damage the circuit board, which can be costly to repair.

The first step is to dry the key fob completely. You can do this in a variety of ways. You can put it in a bag with silica packets to soak up the moisture. You can also use rice that has not been cooked, but it is important not to touch the key fob while it's still wet, as this could contaminate the internal components.

You can also clean the contacts of the circuit board by using isopropyl or electronic cleaner. If the chip has been damaged, it's probably best to accept that you'll need a replacement key fob.

Diagnostics of a fault

If your check engine light is on and the fault code is present, it can be difficult to pinpoint the issue without the use of a diagnostic scanner commonly referred to as an OBD 2. They are available in Bluetooth models that connect to your phone or standard models with an attached reader.

The throttle position sensor (TPS) located in the located in the i20, could be damaged. The sensor is used to measure the opening angle of throttle valve. This information is transmitted to the control unit that aids in calculating the amount of fuel required. A malfunctioning throttle sensor can result in abrupt acceleration, erratic RPM changes and a reduction in engine performance.

Another issue common to the i20s is a faulty transmission. The transmission is a complex component with a variety of gears that are connected to transfer the power from the engine. The friction between the gears cause wear and tear that can cause the transmission to fail. Grinding or clunking sounds and rapid acceleration that is jerky are signs of an unreliable gearbox.

Spark plugs are yet another issue for the i20. Faulty spark plugs can damage the engine because they do not deliver the correct amounts of sparks to each cylinder. If they are not checked, a damaged spark plug can result in severe and expensive engine damage.
