Hyundai I10 Key's History Of Hyundai I10 Key In 10 Milestones
How to Fix a Problem With Your Hyundai i20 Key Fob
Hyundai i20 owners are able to lock and unlock their vehicles remotely. They can also start the vehicle in advance and track the key fob's functions using an app on their smartphone.
However, occasionally the key fob might stop working due to some reason. This could be due to an unresponsive battery, water damage or signal interference.
Battery
Hyundai has developed a smart key fob that is able to perform a variety of remote functions like locking and unlocking your doors, launching your car and even activating the panic button. It's a great way to save time and energy for drivers, but can be frustrating when it doesn't work as intended. There are several things you can do if your Hyundai i20's key fob isn't working correctly.
The first step is to check the battery. The majority of smart key fobs utilize batteries that are coin-cell and is easily replaced in minutes. This is typically the fastest and most cost-effective method to solve the issue. Replacement batteries are available in many stores or online. Once you have a new battery in place then re-open the key fob to ensure that the battery is sitting in the correct place and is in contact with all of the connections.
Be sure to snap a photo or take a note of where the old battery was positioned in the circuit board before removing it. This will help you replace the battery the same way. The majority of Hyundai smart key fobs have the CR2032 battery that is sold in a variety of shops and on the internet. Close your key fob after installing the battery and testing it.
Contacts
If your Hyundai key fob stopped working completely out of the blue and you've not dropped it, you may be dealing with a defective internal chip. The receiver module inside the car utilizes radio frequency signals to communicate with the remote. If the signals are disrupted by nearby transmitters, or objects the key fob might stop working properly.
Think about the Hyundai Digital Key system if your goal is to lock, unlock, and start your car on your way to work in Reno. This innovative keyless entry system operates via an app for smartphones and lets you share Digital Key access with up to three others. This can be helpful when you offer an individual a ride or when you're leaving your car with valet services.
The most common reason for the Hyundai i20 key fob to cease working is an inactive battery. It's time to change the battery if yours shows signs of aging like a slow operation or no response at any time. Although replacing the Hyundai keyfob battery is not difficult, you should be aware of certain things before beginning. Make a sketch or a note about how the old battery is laid within the circuit board. This will help you put the new battery in the same position.
Water Damage
The rubber seals on the fob's key seal the electronic chip from water. So, if it survives the splash of water that comes from a washer or an evaporation in light rain, it's not likely to be damaged. If you drop it in the ocean or a pool and the water sank into the seals, causing damage to the circuit board. This can be a costly repair.
The first step is to dry the key fob thoroughly. This can be done in various ways. You can put it in a plastic bag and then cover it with silica gel packets which will draw the moisture out of it. Alternately, you can make use of rice that isn't cooked but it's important not to contact the key fob when it's still moist because it could cause contamination to the internal components.
Using isopropyl alcohol or an electronic cleaner could also be helpful in cleaning the contacts on the circuit board. If the chip is damaged it is best to accept that you'll need to replace the key fob.
It is simple to replace the battery in your Hyundai key fob. The procedure is generally not messy. You can refer to a YouTube tutorial or your owner's manual guide you through the process. It's a good idea to keep an extra key fob in case you can drive your car while waiting for your key to be repaired.
Diagnosis of a Fault
If your check engine light is on and the fault code is present, it may be difficult to pinpoint the issue without the help of a diagnostic scanner often referred to as an OBD 2. These are available in Bluetooth versions which connect to your phone or standard models with an OBD 2 reader.
The throttle position sensor (TPS), which is located in the i20 can fail. The sensor is responsible for determining the opening angle of the throttle valve. This information is transmitted to an electronic control unit, which contributes to the calculation for the amount of fuel required. A malfunctioning throttle sensor will result in jerky acceleration, RPM fluctuations and decreased engine performance.
Another issue that is common in the i20s is the transmission that is defective. The transmission is a complicated part that has a lot of gears that are connected to transfer the power from the engine. As time passes the friction between gears could cause the transmission to suffer failure. Signs of a defective transmission include clunking or grinding sounds and rapid acceleration that is jerky.
The spark plugs in the i20 are another common problem area. The problem with defective spark plugs is that they can harm the engine because they do not deliver the correct amounts of sparks to every cylinder. A damaged spark plug could result in cost ly and serious engine damage if ignored.
