G28CarKeys lets you to unlock your Picanto and start it. The key also comes with an embedded security chip that deactivates the car's immobiliser system.
It doesn't matter if you're in a store parking lot with full hands or just running your weekly errands, the key fob can be used to lock and unlock your vehicle. However, it may be unable to function due to a variety of reasons.
Transponder Key
Modern technology has enabled us to enjoy many advantages in our cars. One of these advantages is the appearance of transponder keys that allow you to start your car using an ignition key that has an RFID chip. The chip transmits an indication to the immobilizer to let it know that you have the correct key to start your car. It also helps reduce the possibility of theft from your vehicle. It can be harder to duplicate this kind of key, but it's not impossible. You should always contact an auto locksmith in the event that you require a transponder key replacement.
Before calling a locksmith should have all the relevant information about your car ready. This includes the VIN number year, model, year and the trim (options). This will help them locate the right key for your vehicle quickly. You can also save money. Transponders cost more than a key made of metal, but not so much as a new ignition.
A key fob with chip technology is more secure than a standard metal key. It is more difficult to duplicate, and it's not as easy to heat wire. The chip in the keyfob communicates to the computer in your vehicle. This lets it know that you have the correct keys and authorize it to start. This is a great way to feel at ease about the security of your car.
Keyless Entry System
Many cars come with the keyless entry option. As opposed to traditional keys that require the user to insert the keys into the lock and turn them, this system sends radio signals to the vehicle. If the car determines that the key fob is within the range, it will either unlock the vehicle or turn on the engine. Some systems allow the driver to open the trunk and windows by pushing an icon on the key fob.
It is more convenient to use a keyless lock particularly in colder weather. This way, you don't have to insert your key into the lock, and this can protect against damage caused by dust or ice on the lock mechanism. However, it is important to keep in mind that a lock with the keyless system won't work in the event of a power loss or if the battery fails. Therefore, it is advised to keep an emergency key in your glove box of your vehicle.
A keyless system also provides more security than a traditional key. For instance, some systems will automatically lock the vehicle when the driver leaves, and it can also shut down the engine in the event that the driver does not remember to do this. These features are particularly helpful when the vehicle is in a place with high rates of crime or the owner is concerned about leaving valuables inside the vehicle.
Keyless Start System
A keyless start system lets you open and start your vehicle without the need for a mechanical ignition key. It utilizes the transponder in your smart fob to transmit an identification number that is authenticated by the vehicle's anti-theft system. If the smart fob is within the vehicle's range, it broadcasts a signal to the car's antennas. They triggers the engine exactly as if you put a key in the ignition.
These systems are becoming increasingly widespread in both domestic and imported vehicles. The push button turns on the engine, but also turns on other electrical features such as the radio. With just one push the button, you can turn on the air conditioner. The second time will shut off the vehicle's electrical features pressing the button once more by putting your foot on brake will stop the engine.
However some drivers forget to place their vehicle in "park" before exiting the vehicle, and this has led to some injuries. Luckily, all systems have safeguards to avoid this issue. Some systems require you to flick the switch or turn it prior to pressing the start button. Others conduct pre-start tests to ensure the car is in Park and that your foot is securely on the brake. Other safety suggestions include reading the owner's manual, observing basic safety rules, and watching NHTSA's video on keyless ignition systems.
Remote Control
The Remote Control System in your Kia helps make your life easier by giving you the ability to lock and unlock your vehicle from anywhere at any moment. This is accomplished through two sensors within the Kia key fob that communicate with the car's standard immobiliser system, which is in the engine control unit (ECU).
When you press one of the operation buttons on your key fob it sends data indicating that the selected key was activated to a data generator 103. The data generator 103 generates trigger data indicating the selected function and transmits it to the transmitter 104. The transmitter 104 adjusts the infrared beam based on the trigger data and then sends it back to the remote control interface 109.
A receiver 110 in the remote control interface 109 takes the modulated infrared light, and demodulates it to find the control code within the carrier wave. The remote control interface 109 then transmits the control signal to the electronic device that activates the desired function in accordance with the control code.

You can replace it yourself by using a slim tool to pry open the battery cover and then replacing it with a new battery (CR2032). You can replace the battery by yourself using an instrument that is thin enough to pull off the cover. Then you can replace it with a new one (CR2032). If you're not sure which battery to choose, you can contact an authorized Kia dealer or service partner. If you decide to replace the battery, be sure to dispose of it according to local laws.
