Once you have a new battery open the key fob to make sure the battery is in the correct place and that it's in contact with all connections.

Be sure to snap a photo or take a note of where the previous battery was positioned on the circuit board prior to taking it out it. This will allow you to install the new battery in the same way.

Take a picture or make note of how the old battery is placed in the circuit board. This will assist you in placing the new battery in the same place.

Water Damage

The key fob features rubber seals to protect the electronic chip inside from water. If it survives a quick splash from a washing-machine or an a short immersion in a light drizzle it's unlikely to get damaged. If you drop it in the ocean or a pool, the water could penetrate the seals, causing damage to the circuit board. This is an expensive repair.

The first step is to dry the key fob completely. This can be accomplished in several 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 Be careful not to be near it while it's still damp. This could contaminate the internal components.

Fault Diagnosis

If your check engine light comes on and a fault code is present it can be difficult to pinpoint the issue without the help of a diagnostic scanner typically referred to as an OBD 2. These are available in Bluetooth versions which connect to your phone or standard models with readers that are connected to the socket.

One of the most frequent problems with i20s is that the throttle position sensor (TPS) develops a fault. This sensor is responsible to measure the opening angle of throttle valve. The information is then sent to an electronic control unit, which 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.

Another issue common to the i20s is the malfunctioning transmission. The transmission is a complicated component that has many gears that connect to transfer power from the engine to the wheels. As time passes the friction between gears could cause the transmission to suffer failure. The signs of a damaged transmission include clunking or grinding sounds and an abrupt acceleration.

The spark plugs inside the i20 are a different common issue area. The problem with the plugs is that they can cause engine damage by not providing enough sparks to each cylinder. If unchecked, a damaged spark plug can cause serious and costly engine damage.
