how do i replace my lost hyundai key to Fix a Problem With Your Hyundai i20 Key Fob

i lost my hyundai car key i20 owners can to lock and unlock their cars remotely. They can also start their vehicle prior to time and monitor the functions of their key fob via a mobile app using their smartphone.

However, occasionally the key fob will stop working for some reason. It could be due a dead battery, water damage or signal interference.

Battery

Hyundai has created the smart key fob for their vehicles, which allows you to perform a range of remote functions like locking and unlocking doors, launching your vehicle and triggering a panic button. It's a great way to save time and energy for drivers, however it can be frustrating when the system doesn't work correctly. There are a few things you can do if your Hyundai i20's key fob isn't functioning properly.

The first step is to check the battery. Most smart key fobs make use of the coin cell battery which is easily replaced in minutes. This is the fastest and cheapest way to fix your problem. You can find replacement batteries in most stores as well as online. 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.

Be sure to capture a photograph or take a note of how the old battery was positioned on the circuit board prior removing it. This will help you install the new battery in the same manner. Most Hyundai smart keyfobs use the CR2032 batteries, which are sold in most shops or online. Once you have the battery installed close your key fob and then test it to determine if it's functioning again.

Contacts

If your Hyundai key fob stopped working completely out of the blue and you've not dropped it, you could be experiencing a malfunctioning internal chip. The receiver module in your vehicle relies on a radio frequency signal to communicate with the remote control, therefore when this signal is interfered with by nearby transmitters or objects, it could cause the key fob to not function correctly.

If you're looking to find a clever way to unlock, lock and start your vehicle during your Reno commute, think about the Hyundai Digital Key system. This advanced keyless system operates with an app on your smartphone and allows you to share Digital Key access up to three persons. This is useful if you are giving a friend the opportunity to ride with you or leave your vehicle with valet service.

A dead battery is the most frequent cause of the Hyundai i20's key fob not functioning. It's time to change the battery if yours shows signs of aging, such as slow operation or no response at any time. While replacing your Hyundai keyfob battery is not difficult, you must be aware of a few things prior to starting. Make a sketch or an outline of the way that the old battery is laid within the circuit board. This will help you place the new battery in the same spot.

Water Damage

The key fob comes with rubber seals to protect the chip's electronic components from water. If it survives a quick splash from a washing-machine, or a brief immersion in a light drizzle it's unlikely to get damaged. However, if you've dropped it in a pool or ocean then the water can penetrate the seals and damage the circuit board, which can be costly to repair.

The first step is to dry the key fob completely. You can do this in a variety of ways. You can put it in a plastic container with silica gel packets that will suck the moisture out of it. Or, you could use rice that has not been cooked, but it is crucial not to touch the key fob while 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 fried, it's likely that you'll require a replacement key fob.

Replacing the battery on a Hyundai key fob is straightforward and usually not very messy. You can follow an YouTube video tutorial to help you with the procedure or refer to your owner's manual. It's a great idea keep a spare key fob so you can drive your car while you wait for your key to be repaired.

Diagnostics of a fault

If your check engine light is on and there is a fault code, it can be difficult to pinpoint the issue without the use of a diagnostic scanner, typically referred to as an OBD 2. These can be purchased in Bluetooth versions that connect to your smartphone, or standard models that have an OBD 2 reader.

The throttle position sensor (TPS), which is located within the i20, may fail. The sensor is used to determine the opening angle of throttle valve. This information is transmitted to the control unit, which is used to calculate the amount of fuel required. A malfunctioning throttle position sensor could result in lower engine performance, jerky acceleration, and RPM fluctuations while driving.

Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complex part with a variety of gears that mesh together to transfer power from the engine to wheels. In time friction between gears can lead to the transmission's failure. Clanging or grinding sounds as well as the jerky acceleration can be signs of the gearbox being damaged.

Spark plugs are yet another area of concern for the i20. A defective plug could cause engine damage due to not delivering enough sparks to every engine. If unchecked a damaged spark plug could result in serious and costly engine damage.
