Contacts

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

Water Damage

The rubber seals on the key fob guard the electronic chip from water. If it can withstand a brief splash from a washing-machine, or a brief immersion in light rain, it's unlikely to get damaged. If you drop it in the ocean or in a pool the water could get into the seals, causing damage to the circuit board. This is an expensive repair.

The first step is to dry the key fob completely. It is possible to do this in a variety of ways. You can place it in a plastic bag containing silica gel bags that will suck the moisture out of it. Alternatively, you can make use of rice that isn't cooked but it's crucial not to touch the key fob while it's still wet as this could contaminate the internal components.

Diagnosis of a Fault

It can be difficult to diagnose the cause of a problem when your check engine light is flashing and you have a fault code. This is the reason why the diagnostic scanner is typically called an OBD 2 (or OBD 2 in the UK). These are available in Bluetooth models that connect to phones or standard models that have an attached reader to the socket.

One of the most common problems with i20s is that the throttle position sensor (TPS) becomes defective. This sensor is responsible for measuring 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 position sensor can cause a reduction in engine performance, jerky acceleration, and RPM fluctuations during driving.

Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complex component with many gears that mesh together to transfer power from the engine to the wheels. Over time the friction between gears could cause the transmission to suffer failure. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged.

The spark plugs of the i20 are a second common problem area. A defective spark plug can damage the engine because they do not deliver the correct amounts of sparks to the cylinders. A damaged spark plug can result in costly and serious engine damage if ignored.
