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 in advance and monitor key fob functions via an app on their smartphone.

Sometimes the key fob can cease to function. It could be due to a dead battery, water damage, or signal interference.

Battery

Hyundai has created a smart key fob that can be used to perform various remote functions, such as locking and unlocking your doors, starting your car and even activating the panic button. It's a great convenience for drivers, helping them save time and effort, but it can be challenging when the system stops working correctly. There are several things you can do in the event that your Hyundai i20's primary fob is not working properly.

The first step is to test the battery. Most smart key fobs are powered by a coin-cell battery that can be replaced in just a few minutes. This is usually the quickest and most cost-effective method to resolve the issue. Replacement batteries are available in many stores or online. Re-open the keyfob after installing the new battery to verify that the battery is in the right position and is in contact with all the connections.

Take a photo or note the position of the old battery in the circuit before removing it. This will help you install the new battery in the same manner. The majority of Hyundai smart keyfobs are equipped with CR2032 batteries, which are available in most shops or online. Close your key fob after you have installed the battery, and then test it.

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 in the car utilizes radio frequency signals to communicate with the remote. If these signals are interrupted by nearby transmitters, or other objects the key fob could stop working properly.

If you're looking for a smart 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 on your smartphone that allows sharing Digital Key access with up to three other people. This is useful if you give a friend an escort or leaving your vehicle with valet services.

The most common reason for a Hyundai i20 key fob to stop working is the battery is dead. If yours is showing symptoms of dying, like slow operation or not responding at all, it's time to replace the battery. Although the process of replacing your Hyundai keyfob battery isn't difficult, you must be aware of certain things before you begin. The first step is to take note of how the old battery sits inside the circuit board or take a picture. This will allow you to place the new battery in the same location.

Water Damage

The rubber seals on the key fob shield the chip's electronic components from water. If it is able to survive a quick splash from a washing machine, or an a short immersion in a light rain it is unlikely to be damaged. If you dropped it in the ocean or in a pool the water could get into the seals, damaging the circuit board. This can be a costly repair.

The first step is to dry the key fob thoroughly. You can do this in a variety of ways. It can be placed in a plastic container with silica gel bags that will absorb the moisture out of it. You can also use uncooked rice however, be careful not to touch it while it's still damp. This could lead to contamination of its internal components.

Using alcohol such as isopropyl or an electronic cleaner could also be helpful in cleaning the contacts on the circuit board. If the chip is in danger of being damaged it's best to accept you'll need to replace the key fob.

Replacing the battery on a Hyundai key fob is simple and generally not messy. You can follow an YouTube video tutorial to assist you along the way or consult the owner's manual. It's a good idea to keep a spare key fob on the go so that you are able to continue driving your car while you wait for the repair key to arrive.

Troubleshooting


It can be difficult to diagnose an issue if your check engine light is illuminated and you have a fault code. This is the reason why an OBD diagnostic scanner is usually known as an OBD 2 (or OBD 2 in the UK). 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), which is located in the i20 can fail. This sensor is accountable to measure the opening angle of the throttle valve. The data is sent to a control unit, which contributes to the calculation for the amount of fuel required. G28 Car Keys can cause rapid acceleration that is jerky, fluctuations in RPM and a decrease in engine performance.

Another issue common to i20s is the faulty transmission. The transmission is a complicated component that has many gears that mesh together to transfer power from the engine to the wheels. The friction between the gears causes wear and tear that can cause the transmission to fail. The sound of grinding or clunking and an acceleration that is jerky can indicate an unreliable gearbox.

The spark plugs inside the i20 are a different common issue area. A defective plug can cause damage to engines by not delivering enough sparks to every engine. If not checked an unclean spark plug could result in serious and expensive engine damage.
