Why Hyundai I10 Key Isn't As Easy As You Think How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai I20 owners can lock and unlock their cars remotely. They can also start their vehicle in advance and monitor key fob functions by using a mobile application on their mobile.


However, sometimes the key fob will stop functioning for a reason. It could be due to a dead battery, water damage or signal interference.

Battery

Hyundai has created the smart key fob for their vehicles that allows you to use a variety of remote functions like locking and unlocking doors, starting your vehicle, and even pressing panic buttons. It's a great way to save time and energy for drivers, however it can be a hassle if it doesn't work as intended. There are several things you can do to fix your Hyundai i20's key fob isn't working correctly.

The first step is to check the battery. The majority of smart key fobs utilize batteries that are coin-cell and can be replaced in a matter of minutes. This is typically the fastest and most affordable way to resolve the issue. Replacement batteries are available in all stores and online. Once you have a new battery then re-open the key fob to make sure the battery is sitting in the proper position and that it is in contact with all connections.

Note down the location of the old battery within the circuit before taking it out. This will allow you to install the new battery the same way. Most Hyundai smart key fobs use batteries that are CR2032, which are found in many shops and on the internet. Close your key fob after you have installed the battery and test it.

Contacts

If your Hyundai key fob has stopped working completely out of the blue and you've not dropped it, you may be dealing with a defective internal chip. The receiver module inside your car uses a radio frequency signal to communicate with the remote control, so when this signal is blocked by nearby transmitters or objects, it could cause the key fob to stop functioning correctly.

Take a look at the Hyundai Digital key system if you want to lock, unlock, and start your vehicle while you commute to Reno. This innovative keyless entry system is operated via an app on your smartphone that lets you share Digital Key access with up three other people. This is useful when you offer your friend a ride when leaving your car with valet services.

The most frequent reason for the Hyundai i20 key fob not to function is an inactive battery. If yours is showing signs of dying, like slow operation or not responding at all, it's time to replace the battery. While replacing your Hyundai keyfob's battery isn't difficult, you should be aware of certain things prior to starting. First, take a note of the way that the old battery is laid on the circuit board or take a photo. This will enable you to place the new battery in the same location.

Water Damage

The key fob comes with rubber seals to shield the chip inside from water. Therefore, if it withstands a splash of water from a washing machine or an evaporation in light rain, it's not likely to be damaged. If you drop it in a pool or ocean and the water sank into the seals, damaging the circuit board. This is an expensive repair.

The first step is to dry the key fob completely. This can be accomplished in several ways. You can place it in a plastic bag and then cover it with silica gel packets which will draw the moisture out of it. Alternately, you can make use of uncooked rice, but it's crucial not to contact the key fob when it's still wet as this could contaminate the internal components.

Using isopropyl alcohol or an electronic cleaner could also be helpful in cleaning the contacts on the circuit board. If the chip has been damaged, it's probably best to accept that you'll require a new key fob.

It is simple to change the battery on your Hyundai key fob. The procedure is generally not difficult. You can follow an YouTube tutorial video to help you with the procedure or consult the owner's manual. It's always a good idea have a spare key fob on for you in case you need to continue driving your car while waiting for the key repair to arrive.

Troubleshooting

If your check engine light is on and there is a fault code, it may be difficult to determine the problem without the use of a diagnostic scanner often referred to as an OBD 2. They are available in Bluetooth models that connect to phones or standard models that have an OBD 2 reader that is connected to the socket.

The throttle position sensor (TPS) located in the located in the i20 can become defective. This sensor is used to measure the opening angle of throttle valve. G28CarKeys is sent to the control unit and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle position sensor can result in a decrease in engine performance, jerky acceleration, and RPM fluctuations while driving.

Another issue that is common in i20s is the faulty transmission. The transmission is a complicated component that contains a number of gears that work together to transfer power from the engine. In time, the friction between the gears can lead to the transmission's failure. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged.

The spark plugs of the i20 are another common problem area. A defective spark plug can damage the engine because they do not deliver the right amount of sparks to every cylinder. If not checked the damaged spark plug can result in severe and expensive engine damage.
