How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 vehicle owners can lock and unlock their vehicles remotely. They can also start their vehicle prior to time and monitor key fob functions through a mobile application on their smartphones.

However, at times, the key fob may stop functioning due to a reason. This could be due to an unresponsive battery water damage, or signal interference.

Battery

Hyundai has developed the smart key fob for their vehicles. It allows you to perform a variety of remote functions like locking and unlocking doors, launching your vehicle, and even pressing an emergency button. It's an excellent way to save time and energy for drivers, but it can be frustrating when it doesn't work as intended. There are several things you can do in the event that your hyundai i10 key fob i20's primary fob isn't working correctly.

The first thing you need to do is check the battery. Most smart key fobs use the coin cell battery which can be replaced in just a few minutes. This is the easiest and cheapest way to resolve your issue. Replacement batteries are readily available in the majority of stores or on the internet. After you have put the new battery open the key fob to make sure the battery is in the correct position and is in contact with all of the connections.

Be sure to take a photo or make note of where the previous battery was placed on the circuit board prior to taking it out it. This will allow you to install the new battery in the same way. Most Hyundai smart keyfobs are equipped with CR2032 batteries, which can be found at most stores or online. Once you have the battery in place close your key fob, and then test it to determine if it's functioning again.

Contacts

If your Hyundai key fob stopped working from the blue and you've not dropped it, you may have a problem with an internal chip. The receiver module inside your car uses radio frequency signals to communicate with the remote control, so when this signal is affected by nearby transmitters or objects, it might cause the key fob to not function correctly.

If you're looking for a reliable method to lock, unlock and start your vehicle during your Reno commute, consider the Hyundai Digital Key system. The advanced keyless system operates through an app on your smartphone and allows you to share Digital Key access up to three people. This can be useful for giving your friend a ride when leaving your car with valet services.

The most common reason for a Hyundai i20 key fob to stop functioning is an inactive battery. It's time to change the battery if it is showing signs of aging or has a slow response or no response at any time. Although opening and replacing your Hyundai key fob battery isn't difficult however there are a few things you should know before starting. First, make a note of the way that the old battery is laying on the circuit board. You can also take a photograph. This will enable you to place the new battery in the same spot.

Water Damage

The rubber seals on the key fob guard the chip's electronic components from water. So, if it is able to withstand a splash of water from a washing machine or a brief submersion in light rain, it's likely to not be damaged. However, if you've dropped it in the pool or in the ocean, the water could get into the seals and damage the circuit board, which can be expensive to repair.

The first step is to dry the key fob thoroughly. It is possible to do this in a variety of ways. You can place it in a plastic bag and then cover it with silica gel packs that will absorb the moisture out of it. Or, you could use rice that has not been cooked, but it is important not to contact the key fob when it's still damp as it could cause contamination to the internal components.

You can also clean the the circuit board using isopropyl or electronic cleaner. If, however, the chip is fried then it's best to accept that you'll need a replacement key fob.

Replacing the battery on the Hyundai key fob is easy and typically not a big mess. You can refer to an YouTube tutorial or your owner's guide to guide you through the process. It's a good idea to keep an extra key fob in case you can use your vehicle while you wait for the repaired key.

Fault Diagnosis

It isn't easy to pinpoint an issue if your check engine light is on and you have a fault code. This is why a diagnostic scanner is often known as an OBD 2 (or OBD 2 in the UK). These are available in Bluetooth versions which connect to your phone, or standard models with an attached reader.

The throttle position sensor (TPS) is located within the i20, may become damaged. The sensor is responsible for measuring the opening angle of the throttle valve. This information is passed to the control unit and is used to the calculation of the amount of fuel needed. A malfunctioning throttle sensor will result in abrupt acceleration, erratic RPM changes and decreased engine performance.

Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complex part with a variety of gears that connect to transfer power from the engine to wheels. The friction between the gears cause wear and tear, which can cause the transmission to fail. Signs of a defective transmission include grinding or clunking noises and rapid acceleration that is jerky.

The spark plugs inside the i20 are another common problem area. Faulty spark plugs can damage the engine by not delivering the correct amounts of sparks to each cylinder. If not checked the damaged spark plug can result in severe and expensive engine damage.
