How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners can to lock and unlock their cars remotely. They can also start their vehicle in advance and monitor the functions of their key fob by using a mobile application on their smartphone.

Occasionally, the key fob will cease to function. It could be due to an unresponsive battery water damage, or signal interference.

Battery

Hyundai has developed the smart key fob for their vehicles, which allows you to use a variety of remote-controlled functions, such as locking and unlocking doors, starting your vehicle, and even pressing panic buttons. It's an ideal way to save time and energy for drivers, but it can be frustrating when the system isn't working properly. There are a few things you can do when your Hyundai i20's main fob is not working properly.

The first thing you need to do is to check the battery. The majority of smart key fobs are powered by a coin-cell battery, which can be easily replaced in just a few minutes. This is the most efficient and most affordable way to fix the issue. You can purchase replacement batteries in a variety of stores as well as online. After you have put the new battery in place then re-open the key fob to ensure that the battery is sitting in the right position and is in contact with all connections.

Note down the location of the old battery in the circuit before you remove it. This will let you install the new battery in the same way. The majority of Hyundai smart keyfobs are equipped with CR2032 batteries, available in most stores or on the internet. Once you have the battery installed close your key fob and check to determine if it's functioning again.

Contacts

If your Hyundai key fob suddenly stopped working and you haven't dropped it, there could be a problem with the internal chip. The receiver module inside the car uses radio frequency signals to communicate with the remote. If these signals are interfered with by nearby transmitters, or other objects, the key fob may not function properly.

If you're looking to find a clever method to lock, unlock and start your car during your Reno commute, consider the Hyundai i30 spare key Digital Key system. This advanced keyless system works through an app on your smartphone and allows you to share Digital Key access up to three persons. This is helpful for giving your friend a ride when leaving your car with valet services.

The most frequent reason for the Hyundai i20 key fob to cease working is the battery is dead. If yours is showing signs of dying, such as slow operation or not responding at all, it's time to replace the battery. Although replacing and opening the battery in your Hyundai key fob battery isn't too difficult but there are some things to know prior to beginning. First, make a note of how the old battery is laid within the circuit board, or take a photo. This will assist you in placing the new hyundai key fob battery in the same position.

Water Damage

The rubber seals on the key fob guard the chip from water. If it is able to survive a quick splash from a washing-machine or an unintentional dip in a light drizzle, it's unlikely to get damaged. If you drop it in the ocean or pool, the water could get into the seals and cause damage to the circuit board, which can be expensive to repair.

The first step is to dry the key fob thoroughly. This can be accomplished in many ways. You can place it in a plastic container with silica gel packs that will drain the moisture of it. Alternately, you can make use of uncooked rice, but it's crucial not to touch the key fob while it's still wet, as this could contaminate the internal components.

You can also clean the the circuit board by using isopropyl or electronic cleaner. If the chip is in danger of being damaged, it's best to accept you'll have to replace the key fob.

It is a good idea to keep an extra key fob at your side so that you can continue to drive your car while you wait for the repair key to arrive.

Fault Diagnosis

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

The throttle position sensor (TPS) located in the located within the i20, may be damaged. This sensor is responsible for determining the opening angle of the throttle valve. This information is transmitted to the control unit and contributes to the calculation of the amount of fuel required. A problem with the throttle position sensor could result in reduced engine performance, jerky acceleration and RPM fluctuations when driving.

Another issue that is common in the i20s is the malfunctioning transmission. The transmission is a complex component with a variety of gears that work together to transfer power from the engine. The friction between the gears causes wear over time which can cause the transmission to fail. Sounds of grinding or clunking as well as an acceleration that is jerky can indicate an inefficient gearbox.

Spark plugs are another aspect to be concerned about for the i20. The problem with the plugs is that they can cause engine damage by not giving enough sparks to each engine. If not checked an unclean spark plug can cause serious and expensive engine damage.
