How to Fix a Problem With Your Hyundai i20 Key Fob


Hyundai I20 owners can lock and unlock their cars remotely. They can also start the vehicle ahead of time and monitor key-fob functions through a mobile application on their smartphone.

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

Battery

Hyundai has created the smart key fob for their vehicles, which allows users to perform a variety of remote functions including locking and unlocking doors, starting your vehicle and triggering panic buttons. It's a fantastic feature for drivers, helping them save time and effort, but it can be a challenge when the system stops working correctly. There are several things you can do if your Hyundai i20's key fob isn't functioning properly.

The first step is to check the battery. Most smart key fobs use the coin cell battery which is replaced in minutes. This is usually the fastest and most affordable method to fix the problem. Replacement batteries are readily available in the majority of stores or on the internet. After you have put the new battery then re-open the key fob to ensure that the battery is in the right position and that it's making contact with all connections.

Note down the location of the old battery within the circuit before taking it out. This will allow you to replace the battery the same way. The majority of Hyundai smart keyfobs use the CR2032 batteries, which are available at most stores or online. Close your key fob after installing the battery and testing it.

Contacts

If your Hyundai key fob stopped working out of the black and white, and you've still not lost it, you could be dealing with a faulty internal chip. The receiver module inside your car uses radio frequency signals to communicate with the remote control, so when this signal is blocked by nearby transmitters or objects, it may cause the key fob to not function properly.

If you're looking for a reliable way to unlock, lock, and start your car during your Reno commute, look into the Hyundai Digital Key system. This innovative keyless system functions via an app that you can install on your smartphone. It allows you to share Digital Key access up to three people. This is a great feature when you are giving a friend a lift or leaving your vehicle for valet services.

A dead battery is the most common reason for the Hyundai i20's key fob not functioning. If yours is showing signs of dying, like slow operation or not responding at all it's time to replace the battery. Although opening and replacing your Hyundai key fob battery shouldn't be difficult but there are a few points to be aware of prior to starting. Make a sketch or a note about how the old battery is placed on the circuit board. This will help you place the new battery in the same position.

The rubber seals on the key fob guard the electronic chip from water. If it survives a quick splash from a washing-machine or an a short immersion in a light drizzle, it's unlikely to be damaged. If you've dropped it in the pool or ocean then the water can penetrate the seals and damage the circuit board, which can be costly to repair.

The first step is drying the key fob thoroughly. This can be done in many ways. You can put it in a bag with silica bags to absorb the moisture. You can also use uncooked rice however, be careful not to contact it while it's still wet. This could contaminate its internal components.

You can also clean the contacts of the circuit board with 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's a good idea to keep an extra key fob in case you can drive around in your vehicle while waiting for the repaired key.

Fault Diagnosis

If your check engine light comes on and an error code is visible, it may be difficult to identify the issue without the help of a diagnostic scanner commonly referred to as an OBD 2. These are available in Bluetooth models which connect to your phone or standard models that have readers that are connected to the socket.

The throttle position sensor (TPS), which is located in the i20, can become defective. The sensor is responsible for determining the opening angle of the throttle valve. This information is sent to a control unit, which contributes to the calculation for the amount of fuel required. A malfunctioning throttle sensor could cause abrupt acceleration, erratic RPM changes and reduced engine performance.

Transmission issues are another frequent problem in the i20s. The transmission is a complicated component with a variety of gears that are connected to transfer power from the engine. The friction between the gears causes wear and tear that can cause the transmission to fail. Symptoms of a faulty transmission include clunking or grinding sounds and an abrupt acceleration.

The spark plugs of the i20 are a different common issue area. A defective plug could cause engine damage due to not delivering enough sparks to every engine. A damaged spark plug can cause costly and serious engine damage if left unchecked.
