A Comprehensive Guide To Hyundai I10 Key From Start To Finish
How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai I20 vehicle owners can lock and unlock their cars remotely. They can also start the vehicle in advance and track the key fob's functions using a mobile application on their smartphone.

Occasionally the key fob may stop working. This could be due to an unresponsive battery water damage or signal interference.

Battery

Hyundai has created a smart key fob that is able to perform a variety of remote functions, like locking and unlocking your doors, starting your car and even activating the panic button. It's an ideal way to save time and energy for drivers, but can be frustrating when the system doesn't function properly. There are a few options you can do in the event that your Hyundai i20's primary fob isn't working properly.

The first thing to do is check the battery. Most smart key fobs are powered by a coin-cell battery, which can be easily replaced in just a few minutes. This is the most efficient and cheapest method to fix the issue. Replacement batteries are readily available in the majority of stores or on the internet. Re-open the keyfob after installing the new battery to verify that the battery is in the correct location and that it is in contact with all the connections.

Note down the position of the old battery in the circuit before removing it. This will assist you in installing the new battery in the same manner. The majority of Hyundai smart key fobs utilize CR2032 batteries, available in most shops or online. Close hyundai key after you have installed the battery, and then test it.

Contacts

If your Hyundai key fob stopped working from the blue and you haven't dropped it, you could have a problem with an internal chip. The receiver module in the car utilizes radio frequency signals to communicate with the remote. If these signals are obstructed by nearby transmitters or other objects the key fob could not function properly.

If you're looking for a smart way to unlock, lock and start your vehicle during your Reno commute, you should consider the Hyundai Digital Key system. This innovative keyless system functions via an app on your smartphone and allows you to share Digital Key access up to three persons. This is a great feature when you're giving someone a lift or leaving your vehicle with valet services.

A dead battery is the most frequent cause of an Hyundai i20's key fob not working. If yours is showing signs of dying, such as slow operation or not responding at all, it's time to replace the battery. Although replacing your Hyundai keyfob's battery isn't difficult, you must be aware of a few things prior to beginning. First, take note of the way that the old battery is laying on the circuit board or take a photo. This will enable you to place the new battery at the same place.

Water Damage

The rubber seals on the key fob guard the chip's electronic components from water. Therefore, if it withstands the splash of water from a washing machine or an evaporation in light rain it's unlikely to be damaged. If you drop it in an ocean or pool, the water could penetrate the seals, damaging the circuit board. This is an expensive repair.

The first step is to dry the key fob thoroughly. It can be done in a variety of ways. It can be placed in a plastic bag with silica gel packets which will absorb the moisture out of it. Or, you could make use of rice that isn't cooked but it's important not to contact the key fob when it's still wet, as this could contaminate the internal components.

You can also clean the contacts of the circuit board using isopropyl or electronic cleaner. If, however, the chip is damaged, it's probably best to accept that you'll need to replace the key fob.

It is simple to replace the battery in your Hyundai key fob. The process is usually not a hassle. You can follow a YouTube tutorial or your owner's guide to guide you through the process. It's a good idea keep an extra key fob on hand so you can use your vehicle while you wait for your key to be repaired.


Fault Diagnosis

It isn't easy to pinpoint a problem if your check engine light is flashing and you have a fault-code. This is why the diagnostic scanner is typically called an OBD 2 (or OBD 2 in the United Kingdom). These can be purchased in Bluetooth versions that connect to your smartphone, or standard models with an attached reader.

One of the most common problems with i20s is the throttle position sensor (TPS) is damaged. This sensor is responsible to measure the opening angle of the throttle valve. The information is then sent to the control unit and is used to the calculation of the amount of fuel needed. A damaged throttle sensor can result in rapid acceleration that is jerky, fluctuations in RPM and a decrease in engine performance.

Transmission problems are another common issue for i20s. The transmission is a complicated part with a variety of gears that connect to transfer power from the engine to the wheels. Over time the friction between gears could cause the transmission to suffer failure. Grinding or clunking sounds and the jerky acceleration can be signs of a faulty gearbox.

The spark plugs in the i20 are a different common issue area. A defective spark plug can damage the engine by not delivering the correct amounts of sparks to the cylinders. If they are not checked a damaged spark plug can cause serious and costly engine damage.
