How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners are able to lock and unlock their vehicles remotely. They can also start their vehicle ahead of time and check key-fob functions through an app for their smartphone.

Occasionally, the key fob will cease to function. It could be due to a dead battery or water damage, or signal interference.

Battery

Hyundai has created a smart key fob that is able to perform various remote functions, including locking and unlocking your doors, starting your car and even triggering the panic button. It's a wonderful feature for drivers to save time and effort, however it can be challenging when the system stops working correctly. If you're struggling to get your Hyundai i20 key fob to function properly There are several options you can try to fix the issue.

It is possible to purchase replacement batteries in many stores as well as online. Re-open the keyfob after installing the new battery to make sure that the battery is in the correct location and that it is in contact with all connections.

Take a picture or note the position of the old battery within the circuit before removing it. This will allow you to replace the battery the same way. Most Hyundai smart keyfobs use the CR2032 batteries, which are sold in most shops or online. Close your key fob after you have installed the battery, and then test it.

Contacts

If your Hyundai key fob has stopped working completely out of the white of the night and you haven't lost it, you may be experiencing a malfunctioning internal chip. The receiver module in your vehicle relies on radio frequency signals to communicate with the remote control, therefore if this signals are being blocked by nearby transmitters or objects, it might cause the key fob to stop functioning properly.

You should consider the Hyundai Digital Key system if you want to lock, unlock, and start your vehicle on your way to work in Reno. This advanced keyless entry system is operated via a smartphone app and lets you share Digital Key access with up to three others. This is helpful when you're giving a friend the opportunity to ride with you or leave your vehicle with valet service.

A dead battery is the main reason for an Hyundai i20's key fob not working. If yours is displaying signs of dying, such as slow operation or not responding at all, it's time to replace the battery. Although replacing your Hyundai keyfob battery isn't difficult, you should be aware of certain things prior to beginning. Take a photo or take a note about how the old battery is placed within the circuit board. This will help you put the new hyundai keys battery in the same place.

Water Damage

The rubber seals on the fob's key seal the electronic chip from water. If it is able to survive a quick splash from a washing-machine, or an a short immersion in light rain, it's unlikely to be damaged. If you've dropped it in a pool or the ocean, then the water could penetrate the seals and cause damage to the circuit board, which is expensive to repair.

The first step is drying the key fob thoroughly. This can be accomplished in many ways. It can be placed in a bag along with silica bags to absorb the moisture. You can also use uncooked rice However, be cautious not to be near it while it's still wet. It could be contaminated by its internal components.

Using alcohol such as isopropyl or an electronic cleaner can also help in cleaning the contacts on the circuit board. If the chip is in danger of being damaged and you suspect it, you'll need to replace the key fob.

Fault Diagnosis

If your check engine light is on and the fault code is present, it may be difficult to identify the issue without the aid of a diagnostic scanner, commonly referred to as an OBD 2. These can be purchased in Bluetooth models that connect to your phone or standard models that have an attached reader.

One of the most frequent problems with i20s is that the throttle position sensor (TPS) is defective. This sensor is responsible for measuring the opening angle of the throttle valve. The data is sent to a control unit, which aids in calculating the amount of fuel needed. A damaged throttle sensor can result in rapid acceleration that is jerky, fluctuations in RPM and reduced engine performance.

Another problem that is frequently found in i20s is the faulty transmission. The transmission is a complex component that has many gears that work together to transfer power from the engine to wheels. The friction between the gears causes wear and tear that can cause the transmission to fail. The sound of grinding or clunking and an acceleration that is jerky can indicate an unreliable gearbox.

Spark plugs are another area of concern for the i20. A defective plug can cause engine damage by not providing enough sparks to each cylinder. If they are not checked a damaged spark plug can result in severe and expensive engine damage.
