How to Fix a Problem With Your Hyundai i20 Key Fob

2014 Hyundai santa fe key fob Programming i20 vehicle owners can lock and unlock their cars remotely. They can also start their vehicle prior to time and monitor key fob functions via a mobile app on their smartphone.

Sometimes the key fob might cease to function. This could be caused by the battery being dead or water damage, or signal interference.

Battery

Hyundai has developed the smart key fob for their vehicles, which allows you to use a variety of remote-controlled functions, such as locking and unlocking doors, starting your vehicle, and even triggering a panic button. It's a wonderful feature for drivers, helping them save time and effort, however it can be difficult when the system ceases to function properly. If you're experiencing difficulty getting your Hyundai i20 key fob to perform as it should there are a few things you can try to resolve the issue.

The first step is to test the battery. Most smart key fobs are powered by a coin cell battery, which can be replaced in just a few minutes. This is the fastest and cheapest method to fix the issue. You can find replacement hyundai car key batteries in most stores as well as online. After you have put the new battery, re-open the key fob to make sure the battery is in the proper position and is in contact with all connections.

Take a picture or note the position of the old battery within the circuit before you remove it. This will let you install the new battery the same way. Most Hyundai smart keyfobs have CR2032 batteries, which are available 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 stopped working out of the black and white, and you've still not lost it, you may be dealing with a defective internal chip. The receiver module in your vehicle relies on radio frequency signals to communicate with the remote control, so it is possible that the signals are interfered with by nearby transmitters or objects, it can cause the key fob to stop functioning correctly.

If you're looking for an efficient method to lock, unlock, and start your car during your Reno commute, consider the Hyundai Digital Key system. This advanced keyless entry system operates via an app for smartphones and lets you share Digital Key access with up to three other people. This is a great feature when you're giving a friend an escort or leaving your vehicle with valet services.

A dead battery is the primary cause of a Hyundai i20's key fob not functioning. If yours is showing indications of dying, such as slow operation or not responding at all it's time to replace the battery. While replacing and opening the battery in your Hyundai key fob battery isn't difficult but there are some things to know prior to beginning. The first step is to take note of how the old battery is laying on the circuit board or take a picture. This will help you place the new battery at the same place.

Water Damage

The rubber seals on the key fob protect the electronic chip from water. If it survives a quick splash from a washing machine, or a brief immersion in light rain it's unlikely to be damaged. However, if you've dropped it into the ocean or pool, the water may get through the seals and cause damage to the circuit board, which can be costly to repair.

The first step is drying the key fob thoroughly. This can be accomplished in many ways. It can be placed in a plastic container with silica gel packs that will absorb the moisture out of it. Alternately, you can make use of rice that isn't cooked but it's important not to touch the key fob while it's still moist because it could cause contamination to the internal components.

Troubleshooting

It isn't always easy to identify problems if your check engine light comes on and you have a fault-code. This is why a diagnostic scanner is often known as an OBD 2 (or OBD 2 in the United Kingdom). They are available in Bluetooth versions that connect to your smartphone, or standard models with an OBD 2 reader.

One of the most frequent problems with i20s is that the throttle position sensor (TPS) becomes defective. This sensor is responsible to determine the opening angle of the throttle valve. This information is sent to the control unit, and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle sensor will result in sudden acceleration, RPM fluctuations and a decrease in engine performance.

Transmission problems are another common issue for i20s. The transmission is a complicated component with a variety of gears that are connected to transfer power from the engine. Over time, the friction between the gears can lead to the transmission's failure. Sounds of grinding or clunking as well as rapid acceleration that is jerky are signs of an unreliable gearbox.

Spark plugs are another aspect to be concerned about for the i20. A defective spark plug can damage the engine by not delivering the correct amounts of sparks to the cylinders. If not checked the damaged spark plug can cause serious and expensive engine damage.
