Re-open the keyfob after installing the new battery to make sure that the battery is in its correct position and is in contact with all the connections.

Be sure to take a picture or make a note of the way in which the old battery was placed in the circuit board prior removing it. This will allow you to install the new battery the same way. The majority of Hyundai smart keyfobs have CR2032 batteries, which are sold in most shops or online. Once you have the battery in place, close up your key fob and check to see if it's working again.

Contacts

If your Hyundai keyfob suddenly stopped working and you weren't able to drop it, it may be a problem with the internal chip.

First, make a note of how the old battery is laying on the circuit board. You can also take a photograph. This will allow you to put the new battery in the same place.

Water Damage

The key fob features rubber seals to protect the chip inside from water. If it can withstand an accidental splash of water from a washing machine, or a brief submersion in light rain, it's not likely to be damaged. If you've dropped it into the pool or in the ocean, 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 completely. This can be accomplished in many 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. You can also make use of uncooked rice, but it's important not to contact the key fob when it's still moist because it could cause contamination to the internal components.

You can also clean the contacts of the circuit board by using isopropyl or electronic cleaner. If, however, the chip is fried then it's best to accept that you'll require a new key fob.

Diagnostics of a fault

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

The throttle position sensor (TPS) is located within the i20, may become damaged. This sensor is accountable to determine the opening angle of throttle valve. This information is transmitted to the control unit and is used to the calculation of the amount of fuel required. A malfunctioning throttle position sensor can result in lower engine performance, jerky acceleration, and RPM fluctuations when driving.

Transmission issues are another frequent issue in i20s. The transmission is a complicated component that has many gears that connect to transfer power from the engine to wheels. The friction between the gears leads to wear over time which can cause the transmission to fail. Clanging or grinding sounds as well as the jerky acceleration can be signs of an unreliable gearbox.

The spark plugs on the i20 are another frequent problem area. A defective spark plug can damage the engine by not delivering the right amount of sparks to the cylinders. If unchecked a damaged spark plug could result in serious and expensive engine damage.
