Battery

Hyundai has created a smart key fob that can be used to perform various remote functions, such as locking and unlocking your doors, starting your vehicle and even activating the panic button. It's a wonderful feature for drivers, helping them save time and effort, but it can be a challenge when the system stops working correctly. If you're having trouble getting your Hyundai i20 key fob to perform as it should there are a few things you can try to fix the problem.

The first step is to check the battery. The majority of smart key fobs are powered by a coin cell battery, which can be easily repaired in a matter of minutes. This is the easiest and cheapest way to fix your problem. Replacement batteries are available in many stores or online. Re-open the keyfob after installing the new battery to ensure that the battery is in the correct position and in contact with all connections.

Take a photo or note the position of the old battery in the circuit before removing it. This will help you install the new battery in the same way. Most Hyundai smart keyfobs have CR2032 batteries, repairer available in most shops or online. Once you have the battery in place, close up your key fob and test it to determine if it's working again.

Contacts

If your Hyundai keyfob suddenly stopped working and you did not drop it, there could be a problem with the internal chip. The receiver module inside your vehicle utilizes a radio frequency signal to communicate with the remote control, therefore if this signals are being disrupted by nearby transmitters or objects, it might cause the key fob to stop functioning correctly.

Think about the Hyundai Digital key system if you're looking to unlock, lock and start your car on your way to work in Reno. This advanced keyless entry system works via an app on your smartphone that allows you to share Digital Key access with up to three others. 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 primary reason for a Hyundai i20's key fob not working. It's time to replace the battery if it shows signs of aging and is slow to operate or no response at any time. While replacing your Hyundai keyfob battery shouldn't be difficult, you should be aware of a few points before you begin. Make a sketch or an outline of the way that the old battery is laid on the circuit board. This will help you place the new battery at the same position.

Water Damage

The key fob is fitted with rubber seals that protect the chip's electronics from water. If it is able to survive a quick splash from a washing machine, or an unintentional dip in light rain it's unlikely to be damaged. If you dropped it in the ocean or a pool, the water could penetrate the seals, damaging the circuit board. This is a costly repair.

The first step is drying the key fob completely. This can be done in many ways. You can put it in a plastic bag containing silica gel bags that will suck the moisture out of it. You can also use rice that is not cooked however, be careful not to touch it while it is still damp. This could lead to contamination of the internal components.

You can also clean the the circuit board using isopropyl or electronic cleaner. If the chip has gone bad it is best to accept that you'll need to replace the key fob.

It's a good idea have a spare key fob on hand so that you can continue driving your car while waiting for the repaired key to arrive.

Diagnosis of a Fault

It isn't easy to pinpoint the cause of a problem when your check engine light is on and you have a fault-code. This is why the diagnostic scanner is typically called an OBD 2 (or OBD 2 in the UK). They are available in Bluetooth versions which connect to your phone or standard models that have an OBD 2 reader.

The throttle position sensor (TPS) located in the located in the i20, could fail. The sensor is responsible for measuring the opening angle of the throttle valve. This information is transmitted to the control unit and is used to the calculation of the amount of fuel needed. A malfunctioning throttle sensor could cause jerky acceleration, RPM fluctuations and decreased engine performance.

Transmission problems are another common problem in i20s. The transmission is a complex component that contains a number of gears that connect to transfer the power from the engine. Over time the friction between the gears can cause the transmission's failure. Sounds of grinding or clunking as well as jerky acceleration are symptoms of a faulty gearbox.

Spark plugs are a different issue for the i20. Spark plugs that are defective can cause engine damage by not giving enough sparks to each cylinder. If unchecked an unclean spark plug could result in serious and expensive engine damage.
