How to Fix a Problem With Your hyundai tucson key i20 Key Fob

Hyundai i20 owners are able to lock and unlock their vehicles remotely. They can also start their vehicle before time and monitor key fob function through a mobile application using their smartphone.

However, sometimes the key fob will stop functioning for a reason. This could be caused by a dead battery or water damage, or signal interference.

Battery

Hyundai has created a smart key fob that is able to perform a variety of remote functions, such as locking and unlocking your doors, starting your vehicle and even activating the panic button. It's a wonderful feature for drivers to save time and effort, but it can be a challenge when the system doesn't function properly. If you're struggling to get your hyundai car key i20 key fob to work properly there are a few things you can do to resolve the issue.

The first step is to test the battery. The majority of smart key fobs have a coin cell battery that is easily replaced in minutes. This is usually the fastest and most cost-effective method to fix the issue. You can purchase replacement batteries at most stores and online. After you have put the new battery in place then re-open the key fob to ensure that the battery is in the correct position and is in contact with all of the connections.

Be sure to capture a photograph or take a note of the way in which the old battery was placed in the circuit board before removing it. This will allow you to install the new battery in the same manner. The majority of Hyundai smart keyfobs are equipped with CR2032 batteries, which are available in most stores or on the internet. 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 may have a problem with an internal chip. The receiver module in your Car key near me uses a radio frequency signal to communicate with the remote control, so it is possible that the signals are disrupted by nearby transmitters or objects, it can cause the key fob to not function properly.

If you're looking to find a clever way to unlock, lock and start your vehicle during your Reno commute, look into the Hyundai Digital Key system. The advanced keyless system operates via an app on your smartphone and allows you to share Digital Key access up to three people. This is useful if you're giving a friend the opportunity to take a ride or leaving your vehicle with valet service.

A dead battery is the most common reason for an Hyundai i20's key fob not working. It's time to change the battery if the one you have is showing signs of aging and is slow to operate or no response at any time. While replacing your hyundai smart key keyfob's battery isn't difficult, you must be aware of a few points prior to starting. Make a sketch or note of how the old battery is placed within the circuit board. This will allow you to place the new battery in the same spot.

Water Damage

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

The first step is to dry the key fob completely. This can be done in many ways. You can place it in a plastic bag with silica gel bags that will draw the moisture out of it. You can also use uncooked rice, but be careful not to touch it while it is still damp. This could contaminate the internal components.

Utilizing isopropyl alcohol or an electronic cleaner can also help in cleaning the contacts on the circuit board. If the chip has gone bad it's best to accept you'll need to replace the key fob.

Replacing the battery in the Hyundai key fob is easy and usually not very messy. You can consult a YouTube tutorial or your owner's manual guide you through the procedure. It's a great idea keep an extra key fob to ensure you can use your vehicle while waiting for the repaired key.

Fault Diagnosis

If your check engine light is on and there is a fault code, it may be difficult to pinpoint the issue without the use of a diagnostic scanner, often referred to as an OBD 2. These are available in Bluetooth versions that connect to phones or standard models with an attached reader to the socket.

One of the most frequent issues with i20s can be that the throttle position sensor (TPS) becomes defective. This sensor is responsible to measure the opening angle of throttle valve. This information is transmitted to the control unit and contributes to the calculation of the amount of fuel required. A malfunctioning throttle position sensor can result in reduced engine performance, jerky acceleration and RPM fluctuations during driving.

Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complicated component that has many gears that work together to transfer power from the engine. In time friction between gears can lead to transmission failure. Signs of a defective transmission include clunking or grinding noises and rapid acceleration that is jerky.

Spark plugs are a different aspect to be concerned about for the i20. The problem with defective spark plugs is that they can harm the engine because they do not deliver the right amount of sparks to each cylinder. If unchecked the damaged spark plug could result in serious and costly engine damage.
