How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners can to lock and unlock their cars remotely. They can also start the vehicle in advance and monitor key fob functions via a mobile application on their smartphone.

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

Battery

Hyundai has created the smart key fob for their vehicles that allows you to perform a range of remote functions like locking and unlocking doors, starting your vehicle, and even pressing an emergency button. It's an ideal way to save time and energy for drivers, but can be frustrating when the system isn't working properly. There are a few things you can do in the event that your Hyundai i20's primary fob isn't functioning properly.

The first step is checking the battery. The majority of smart key fobs are powered by a coin cell battery, which can be easily repaired in a matter of minutes. This is usually the quickest and most cost-effective method to fix the issue. You can buy replacement key for hyundai i10 batteries in many stores as well as online. Re-open the keyfob after installing the new battery to ensure that the battery is in the correct position and in contact with all the connections.

Take a picture or note the position of the old battery within the circuit before you remove it. This will help you replace the battery the same way. Most Hyundai smart key fobs are powered by batteries that are CR2032, which are found in many shops and online. Close your key fob after installing the battery, and then test it.

Contacts

If your Hyundai key fob suddenly stopped working and you weren't able to drop it, it might be a problem with the internal chip. The receiver module inside your vehicle uses a radio frequency signal to communicate with the remote control, therefore if this signals are being affected by nearby transmitters or objects, it can cause the key fob to not function properly.

Consider the Hyundai Digital key system if you want to lock, unlock, and start your car on your way to work in Reno. This innovative keyless entry system works with a smartphone app and lets you share Digital Key access with up to three other people. This is useful if you're giving someone the opportunity to ride with you or leave your vehicle for valet services.

A dead battery is the main cause of an Hyundai i20's key fob not functioning. If yours is displaying indications of dying, such as slow operation or not responding at all it's time to replace the battery. While replacing the Hyundai keyfob battery isn't difficult, you must be aware of a few points before beginning. Make a sketch or notes of how the old battery is placed inside the circuit board. This will assist you in placing the new battery in the same position.

Water Damage

The key fob is fitted with rubber seals to protect the chip's electronics from water. So, if it is able to withstand the splash of water from a washing machine, or the brief submersion of rain, it's not likely to be damaged. If you've dropped it in a pool or the ocean, then the water may get through the seals and damage the circuit board, which can be expensive to repair.

The first step is to dry the key fob completely. This can be accomplished in various ways. It can be placed in a plastic bag containing silica gel bags that will suck the moisture out of it. Or, you could make use of uncooked rice, but it's crucial not to touch the key fob while it's still damp as it could cause contamination to the internal components.

Utilizing isopropyl alcohol or an electronic cleaner could 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.

It is easy to change the battery on your Hyundai key fob. The process is usually not messy. You can follow a YouTube video tutorial to help you through the process or refer to the owner's manual. It's a good idea have an extra key fob at hand so that you can continue to drive your car while waiting for the repaired key to arrive.

Diagnosis of a Fault

It isn't easy to pinpoint problems if your check engine light is on and you have a fault code. This is the reason why a diagnostic scanner is often 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 with a reader attached to the socket.

One of the most frequent problems with i20s is that the throttle position sensor (TPS) is damaged. This sensor is responsible to measure the opening angle of throttle valve. This information is passed to the control unit, and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle position sensor will result in lower engine performance, jerky acceleration, and RPM fluctuations during driving.

Another issue common to the i20s is the transmission that is defective. The transmission is a complex component made up of many gears that mesh together to transfer power from the engine to the wheels. In time, the friction between the gears can lead to the transmission's failure. Signs of a malfunctioning transmission include grinding or clunking noises and jerky acceleration.

Spark plugs are another aspect to be concerned about for the i20. The problem with defective spark plugs is that they can harm the engine by not delivering the correct amounts of sparks to the cylinders. If they are not checked an unclean spark plug can result in severe and expensive engine damage.
