hyundai tucson car key i20 owners are able to lock and unlock their vehicles remotely. They can also start their vehicle in advance and monitor key fob function by using a mobile application using their smartphone.

However, sometimes the key fob may stop functioning for a reason. This could be caused by a dead battery, water damage, or 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 a panic button. It's an excellent way to cut down on time and energy for drivers, but can be frustrating when the system doesn't work correctly. There are a few things you can do to fix your Hyundai i20's key fob isn't functioning properly.

The first step is to check the battery. The majority of smart key fobs have an internal battery that can be replaced in a matter of minutes. This is usually the fastest and most cost-effective method to resolve the issue. You can find replacement batteries in most stores and online. Re-open the keyfob after installing the new battery to make sure that the battery is in its correct position and is in contact with all the connections.

Take a picture or note the position of the old battery in the circuit before taking it out. This will allow you to replace the battery the same way. Most Hyundai smart key fobs use a CR2032 battery which is available in many stores and on the internet. Once you have the battery installed, close up your key fob and test it to see if it's working again.

Contacts

If your Hyundai key fob has stopped working completely out of the blue and you've not dropped it, you could have a problem with an internal chip. The receiver module inside your vehicle utilizes radio frequency signals to communicate with the remote control, therefore when this signal is interfered with by nearby transmitters or objects, it might cause the key fob to not function properly.

If you're looking for an efficient way to unlock, lock and start your vehicle during your Reno commute, think about the Hyundai Digital Key system. This advanced keyless entry system is operated via a smartphone app and lets you share Digital Key access with up to three other people. This is useful when you offer a friend a ride or when you're leaving your car with valet services.

The most frequent reason for a Hyundai i20 key fob to stop working is the battery is dead. If yours is displaying symptoms of dying, like slow operation or not responding at all, it's time to replace the battery. Although opening and replacing the battery in your hyundai accent key key fob battery isn't too difficult but there are a few things to know prior to starting. First, take a note of the way that the old battery is placed on the circuit board. You can also take a picture. This will assist you in placing the new battery in the same location.

Water Damage

The key fob is fitted with rubber seals that protect the chip's electronics from water. If it can withstand a brief splash from a washing-machine, or just a brief dip in a light rain it's unlikely to be damaged. If you drop it in a pool or ocean, the water could penetrate the seals, causing damage to the circuit board. This can be a costly repair.

The first step is drying the key fob completely. This can be accomplished in several ways. It can be placed in a plastic container with silica gel packs that will drain the moisture of it. Alternately, you can use uncooked rice but it's crucial not to contact the key fob when it's still wet as it could cause contamination to the internal components.

Using isopropyl alcohol or an electronic cleaner may also be helpful in cleaning the contacts on the circuit board. However, if the chip is fried, it's probably best to accept that you'll need a replacement key fob.

Replacing the battery in a Hyundai key fob is straightforward and generally not messy. You can follow a YouTube tutorial video to help you along the way or consult the owner's manual. It's a great idea to keep an extra key fob on hand so you can drive your car 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 pinpoint the issue without the use of a diagnostic scanner, commonly called an OBD 2. They are available in Bluetooth versions that connect to your smartphone, or standard models with an integrated reader.

The throttle position sensor (TPS), which is located in the i20, could fail. The sensor is responsible for determining the opening angle of the throttle valve. The data is sent to a control unit, which aids in calculating the amount of fuel required. A malfunctioning throttle position sensor can result in lower engine performance, jerky acceleration, and RPM fluctuations while driving.

Transmission problems are a common issue with i20s. The transmission is a complicated component that has many gears that work together to transfer the power from the engine. As time passes, the friction between the gears can lead to transmission failure. Symptoms of a faulty transmission include clunking, grinding noises and rapid acceleration that is jerky.

The spark plugs in the i20 are a second common problem area. The problem with the plugs is that they can cause engine damage through not giving enough sparks to each cylinder. A damaged spark plug could cause expensive and serious engine damage if ignored.
