How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners can to lock and unlock their vehicle remotely. They can also start their vehicle in advance and track key-fob functionality using an application for mobile devices on their smartphone.

But, sometimes, the key fob may stop working due to some reason. It could be due to an unresponsive battery, water damage or signal interference.

Battery

Hyundai has created a smart key fob that can be used to perform a variety of remote functions, including locking and unlocking your doors, launching your car and even triggering the panic button. It's a fantastic feature for drivers that helps them save time and effort, however it can be a hassle if the system doesn't function properly. There are a few options you can do when your Hyundai i20's main 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, which can be easily replaced in just a few minutes. This is usually the fastest and most cost-effective method to solve the issue. It is possible to purchase replacement batteries in many stores and online. Re-open the keyfob after installing the new battery to ensure that the battery is in the correct position and in contact with all connections.

Make sure to capture a photograph or take a note of how the old battery was placed on the circuit board prior removing it. This will assist you in installing the new battery in the same manner. The majority of Hyundai smart key fobs utilize the CR2032 battery that is found in many shops and on the internet. Close your key fob after installing the battery and then test it.

Contacts

If your hyundai i30 replacement key key fob suddenly stopped working and you did not drop it, there may be a problem in the internal chip. The receiver module in your vehicle uses a radio frequency signal to communicate with the remote control, therefore in the event that this signal is disrupted by nearby transmitters or objects, it may cause the key fob to cease functioning properly.

If you're looking for a reliable method to lock, unlock and start your car during your Reno commute, think about the Hyundai Digital Key system. This advanced keyless entry system is operated via an app for smartphones that lets you share Digital Key access with up to three additional people. This is useful when you are giving a friend an escort or leaving your vehicle for valet services.

The most common reason for a Hyundai i20 key fob not to function is the battery is dead. It's time for a new battery if it is showing signs of age like a slow operation or no response at any time. Although the process of replacing your Hyundai keyfob battery shouldn't be difficult, you must be aware of a few things prior to beginning. The first step is to take note of where the old battery is laid on the circuit board. You can also take a photo. This will help you put the new battery in the same position.

Water Damage

The key fob has rubber seals to protect the chip's electronics from water. If it can withstand the splash of water from a washing machine or an evaporation in light rain, it's likely to not be damaged. If you drop it in the ocean or pool, the water can penetrate the seals and damage the circuit board, which is expensive to repair.

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

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

It's a good idea keep an extra key fob in your side so that you can continue to drive your car while waiting for the replacement key to arrive.

Diagnosis of a Fault

If your check engine light is on and an error code is visible, it can be difficult to determine the problem without the use of a diagnostic scanner commonly called an OBD 2. These are available in Bluetooth models that connect to your mobile or standard models with an attached reader to the socket.

One of the most common problems with i20s is that the throttle position sensor (TPS) develops a fault. The sensor is responsible for measuring the opening angle of the throttle valve. This information is sent to an electronic control unit, which helps calculate the amount of fuel needed. A malfunctioning throttle position sensor will result in a decrease in engine performance, jerky acceleration, and RPM fluctuations while driving.

Another issue that is common in the i20s is the transmission that is defective. The transmission is a complicated component with a variety of gears that work together to transfer power from the engine. The friction between the gears causes wear and tear over time, which could cause the transmission to fail. Signs of a defective transmission include clunking or grinding sounds and jerky acceleration.

Spark plugs are yet another aspect to be concerned about for the i20. Faulty plugs can cause engine damage through not sending enough sparks to every engine. If left unchecked the damaged spark plug can result in severe and costly engine damage.
