Why Hyundai I10 Key Is So Helpful For COVID-19
How to Fix a Problem With Your Hyundai i20 Key Fob
Hyundai I20 owners can lock and unlock their vehicles remotely. They can also start the vehicle ahead of time and check key-fob functionality using an app for their smartphone.
Occasionally the key fob can cease to function. This could be due to a dead battery or water damage, or signal interference.
Battery
Hyundai has created the smart key fob for their vehicles that enables users to perform a variety of remote-controlled functions, such as locking and unlocking doors, starting your vehicle and even activating an emergency button. It's an ideal way to save time and energy for drivers, but can be frustrating when the system doesn't function properly. There are a few options you can do when your Hyundai i20's main fob isn't working properly.
The first step is to check the battery. Most smart key fobs are powered by a coin-cell, which can be easily replaced within minutes. This is usually the quickest and most affordable method to fix the problem. You can purchase replacement batteries at most stores as well as online. Re-open the keyfob after installing the new battery to ensure that the battery is in the proper position and is in contact with all connections.
Take a photo or note the location of the old battery within the circuit before you remove it. This will allow you to install the new battery in the same manner. Most Hyundai smart key fobs use a CR2032 battery which is available in most shops and online. Once you have the battery in place close your key fob and then test it to verify if it's functioning again.
Contacts
If your Hyundai key fob suddenly stopped working and you weren't able to drop it, it could be a problem with the internal chip. The receiver module inside your car uses a radio frequency signal to communicate with the remote control, so if this signals are being blocked by nearby transmitters or objects, it can cause the key fob's functionality to cease correctly.
If you're looking for a smart method to lock, unlock, and start your car during your Reno commute, you should consider 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 persons. This is useful when you're giving someone the opportunity to take a ride or leaving your vehicle in valet service.
The most frequent reason for the Hyundai i20 key fob not to function is the battery is dead. If yours is showing signs of dying, like slow operation or not responding at all, it's time to replace the battery. While replacing the Hyundai keyfob battery shouldn't be difficult, you must be aware of some things before you begin. First, make a note of where the old battery sits on the circuit board or snap a picture. This will help you put the new battery in the same location.
Water Damage
The key fob is fitted with rubber seals to protect the chip's electronics from water. So, if it is able to withstand the splash of water that comes from a washing machine or even a brief immersion in light rain it's unlikely to be damaged. If you've dropped it into the ocean or pool, the water could get into the seals and damage the circuit board, which can be expensive to repair.
The first step is drying the key fob thoroughly. It can be done in many ways. You can put it in a plastic bag with silica gel packs that will draw the moisture out of it. You can also use rice that is not cooked however, be careful not to touch it while it is still damp. This could cause contamination to its internal components.
The use of isopropyl alcohol, or an electronic cleaner may also be helpful in cleaning the contacts on the circuit board. If the chip is damaged, it's probably best to accept that you'll require a new key fob.
It is simple to replace the battery in your Hyundai key fob. The procedure is generally not difficult. You can follow an YouTube video tutorial to assist you with the process or refer to the owner's manual. It's a good idea keep an extra key fob on hand so you can drive your car while you wait for the repaired key.
Diagnostics of a fault
It isn't always easy to identify problems if your check engine light is illuminated and you have a fault-code. This is why an OBD diagnostic scanner is usually called an OBD 2 (or OBD 2 in the United Kingdom). These can be purchased in Bluetooth versions which connect to your smartphone, or standard models that have an OBD 2 reader.
The throttle position sensor (TPS) is located in the i20, could become defective. This sensor is used to determine the opening angle of throttle valve. This information is transmitted to the control unit and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle position sensor can result in reduced engine performance, jerky acceleration and RPM fluctuations during driving.
Another issue common to the i20s is the malfunctioning transmission. The transmission is a complicated part that has a lot of gears that connect to transfer the power from the engine. As time passes friction between gears can lead to the transmission's failure. Sounds of grinding or clunking as well as the jerky acceleration can be signs of an inefficient gearbox.
Spark plugs are an additional issue for the i20. hyundai car keys that are defective can cause engine damage by not sending enough sparks to every cylinder. A damaged spark plug could cause expensive and serious engine damage if not properly checked.
