How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners are able to lock and unlock their vehicle remotely. They can also start their vehicle ahead of time and monitor the functions of their key fob through a mobile application on their smartphone.

Sometimes the key fob can stop working. This could be caused by the battery being dead or water damage, or signal interference.

Battery

Hyundai has created the smart key fob for their vehicles that allows you to use a variety of remote functions including locking and unlocking doors, starting your vehicle and triggering an emergency button. It's a wonderful feature for drivers to save time and effort, but it can be a challenge when the system ceases to function properly. There are a few options you can do to fix your Hyundai i20's key fob is not working properly.

The first step is to examine the battery. The majority of smart key fobs are powered by a coin-cell battery, which can be easily replaced within minutes. This is usually the fastest and most affordable method to fix the issue. You can buy replacement batteries in many stores and online. Re-open the keyfob after installing the new battery to verify that the battery is in its correct position and in contact with all the connections.

Take a photo or note the position of the battery that was removed from the circuit before removing it. This will let you install the new battery the same way. Most Hyundai smart keyfobs have CR2032 batteries, which are sold in most stores or on the internet. Close your key fob after installing the battery and then test it.

Contacts

If your Hyundai keyfob suddenly stopped working and you didn't drop 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 could cease to function properly.

If you're looking for a reliable way to unlock, lock and start your car during your Reno commute, think about the Hyundai Digital Key system. This innovative keyless system functions through an app on your smartphone. It allows you to share Digital Key access up to three people. This can be helpful for giving your friend a ride when you are leaving your car using valet services.

A dead battery is the most common cause of an Hyundai i20's key fob not working. It's time to change the battery if the one you have is showing signs of age and is slow to operate or no response at all. Although replacing your Hyundai keyfob battery shouldn't be difficult, you should be aware of a few things prior to starting. First, take a note of how the old battery is laid on the circuit board or take a photograph. This will help you put the new battery in the same spot.

Water Damage

The key fob comes with rubber seals to shield the electronic chip inside from water. Therefore, if it withstands a splash of water from a washing machine or an evaporation in light rain, it's likely to not be damaged. However, if you've dropped it into the pool or the ocean, then the water could penetrate the seals and cause damage to the circuit board, which is costly to repair.

The first step is to dry the key fob thoroughly. This can be accomplished in several ways. It can be placed in a plastic bag and then cover it with silica gel packs that will suck the moisture out of it. Alternately, you can make use of uncooked rice, but it's crucial not to contact the key fob when it's still wet, as this could contaminate the internal components.

Using alcohol such as isopropyl or an electronic cleaner may also be helpful in cleaning the contacts on the circuit board. If the chip is damaged, it's likely that you'll need a replacement key fob.

It's easy to replace the battery in your Hyundai key fob. The process is typically not messy. You can follow an YouTube tutorial or the owner's manual to guide you through the process. It's a good idea to keep an extra key fob to ensure you can use your vehicle while you wait for your repaired key.

Troubleshooting

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

The throttle position sensor (TPS), which is located in the i20, could be damaged. This sensor is used to measure the opening angle of throttle valve. The data is sent to the control unit, which contributes to the calculation for the amount of fuel needed. A malfunctioning throttle position sensor can result in a decrease in engine performance, jerky acceleration and RPM fluctuations while driving.

Transmission issues are another frequent issue with the i20s. The transmission is a complicated component made up of many gears that interlock to transfer power from the engine to the wheels. The friction between the gears cause wear and tear, which can cause the transmission to fail. Signs of a malfunctioning transmission include clunking or grinding sounds and jerky acceleration.

The spark plugs in the i20 are another frequent problem area. Spark plugs that are defective can cause damage to the engine because they do not deliver the right amount of sparks to each cylinder. A damaged spark plug could result in costly and serious engine damage if left unchecked.
