Once you have a new battery, re-open the key fob to ensure that the battery is in the proper position and that it is in contact with all of the connections.

Make sure you take a photo or make note of where the previous battery was placed in the circuit board prior to removing it. This will enable you to install the new battery the same way.

Contacts

If your Hyundai key fob stopped working from the blue and you haven't dropped it, you may be dealing with a defective internal chip.

Water Damage

The rubber seals on the fob's key seal the chip from water. If it can withstand a splash of water from a washer or even a brief immersion in light rain, it's not likely to be damaged.

The first step is drying the key fob thoroughly. It is possible to do this in a variety of ways. You can place it in a bag along with silica bags to absorb the moisture. You can also use rice that is not cooked, but be careful not to be near it while it's still wet. This could cause contamination to the internal components.

Diagnostics of a fault

If your check engine light comes on and a fault code is present it can be difficult to determine the issue without the use of a diagnostic scanner, commonly referred to as an OBD 2. They are available in Bluetooth versions that connect to your phone or standard models with an attached reader.

The throttle position sensor (TPS) located in the located in the i20, can become damaged. This sensor is used to determine the opening angle of throttle valve. This information is sent to the control unit that aids in calculating the amount of fuel required. A malfunctioning throttle position sensor will result in reduced engine performance, jerky acceleration and RPM variations when driving.

Transmission issues are another frequent problem in the i20s. The transmission is a complex component that has many gears that work together to transfer power from the engine to wheels. The friction between the gears causes wear and tear that can cause the transmission to fail. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged.

Spark plugs are yet another issue for the i20. Spark plugs that are defective can cause engine damage by not providing enough sparks to each engine. If unchecked an unclean spark plug can result in severe and costly engine damage.
