Remotes
The remote controls of Fiat vehicles are similar to keys, but they have an IR LED (infrared). G28 sends an electronic signal to the device that opens or turns off the vehicle when it is pressed. The signal is received by a microprocessor inside the key, which transforms it into a code which is then sent to the device.
This process is known as "keyless entry". The more recent your vehicle is and the more likely to have a keyless entry feature. The more advanced your vehicle has, the more features it will have. This includes everything from locking and unlocking the car using a button to unlocking the doors without having to touch the door handle, and much more.
The key fob is equipped with an integrated circuit chip that communicates with the immobiliser system of the car. The system will determine if the correct key is present by observing a certain sequence of digits inside the transponder chip. If the chip isn't present, or isn't programmed to the correct immobiliser, then the vehicle will not start.
When the key fob is damaged, a locksmith may create a replacement. They'll also need to program the new key to sync with the immobiliser of the car. It is recommended to give your locksmith information regarding your vehicle whenever they call.
Keyless Entry
With a keyless entry feature on your Fiat 500 you can lock or unlock the car with the touch of a button. This technology is becoming increasingly popular across all cars that adds convenience and security to the usage of your vehicle.
If your remote keyless entry system ceases to function examine whether the battery inside the fob has gone dead. Replace the battery by using a newer one with the same voltage size, type, and size as the one that came with it if it has been drained. It is also important to ensure that the battery's contacts are free of dust or corrosion.
The rubber seals on the key fob guard the chip from water. However, prolonged exposure to soapy water or salty water can cause the chip to fail. If your key fob has been exposed to water, remove and let the battery dry completely before replacing it. You can also clean the electronic chip using isopropyl alcohol, or an electronic cleaner.
Although some may think that keyless entry isn't as secure, this system is actually more secure than conventional systems due to the code that unlocks your car is rolled away after each use. This means that even if hackers do intercept the signal it isn't possible for them to gain access to your vehicle.
Transponders
Fiat utilizes a crypto key transponder system, which means that the keys or transponders must be precoded with a secret code that is generated by the Body Control Module (BCM) before being "programmed" into the BCM. A blank key that is not programmed can't be programmed as the BCM must read and write the secret key into the transponder before locking it. This is referred to as"cloning.
