Hyundai i20 owners are able to lock and unlock their vehicles remotely. They can also start their vehicle in advance and monitor key fob function through a mobile application on their mobile.

Sometimes the key fob can stop working. This could be due a dead battery water damage, or signal interference.

Battery

Hyundai has developed a smart key fob that is able to perform various remote functions, such as locking and unlocking your doors, starting your car and even activating the panic button. It's an excellent feature for drivers that helps them save time and effort, but it can be a challenge when the system doesn't function properly. There are a few options you can do to fix your Hyundai i20's key fob isn't working properly.

The first step is to examine the battery. Most smart key fobs make use of batteries that are coin-cell and is replaced in minutes. This is usually the quickest and most affordable method to fix the issue. Replacement batteries are readily available in the majority of stores or on the internet. Re-open the keyfob after installing the new battery to make sure that the battery is in its correct location and that it is in contact with all connections.

Make sure you capture a photograph or take a note of where the old battery was positioned on the circuit board prior removing it. This will allow you to replace the battery the same way. Most Hyundai smart key fobs utilize CR2032 batteries, which can be found in most stores or on the internet. Once you have the battery installed and closed, you can close the key fob, and then test it to determine if it's working again.

Contacts

If your Hyundai key fob has stopped working completely out of the black and white, and you've still not lost it, you could have a problem with an internal chip. The receiver module in 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.

Although the process of replacing your Hyundai keyfob battery is not difficult, you must be aware of certain things prior to starting. Make a sketch or notes of how the old battery is laid within the circuit board. This will help you place the new battery in the same position.

Water Damage

The key fob features rubber seals to shield the electronic chip inside from water. If it can withstand the splash of water from a washing machine or even a brief immersion in light rain, it's likely to not be damaged. If you drop it in a pool or ocean and the water sank into the seals, damaging the circuit board. This is a costly repair.

The first step is drying the key fob thoroughly. This can be accomplished in a variety of ways. You can place it in a bag with silica bags to absorb the moisture. Or, you could make use of rice that isn't cooked but it's important not to touch the key fob while it's still wet, as this could contaminate the internal components.

It's a good idea have an extra key fob in hand so that you can continue driving your vehicle while waiting for the repaired key to arrive.

Troubleshooting

It can be difficult to determine an issue if your check engine light comes on and you have a fault-code. This is why the diagnostic scanner is typically known as an OBD 2 (or OBD 2 in the United Kingdom). They are available in Bluetooth models that connect to phones or standard models that have an attached reader to the socket.

One of the most frequent issues with i20s is the throttle position sensor (TPS) is defective. The sensor is used to measure the opening angle of throttle valve. This information is transmitted to a control unit, which helps calculate the amount of fuel required. A malfunctioning throttle position sensor could cause a reduction in engine performance, jerky acceleration and RPM fluctuations when driving.

Another common problem found in the i20s is the malfunctioning transmission. The transmission is a complicated part with a variety of gears that work together to transfer power from the engine to wheels. The friction between the gears causes wear over time which can cause the transmission to fail. Grinding or clunking sounds and jerky acceleration are symptoms of an unreliable gearbox.

Spark plugs are a different area of concern for the i20. The problem with defective spark plugs is that they can harm the engine because they do not deliver the correct amounts of sparks to each cylinder. A damaged spark plug can cause expensive and serious engine damage if it is not checked.
