Why We Enjoy Fiat 500 Keys (And You Should Also!)
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car that allows it to unlock doors or start the motor. However, the key fob may not function due to a variety of reasons.
A dead battery for the coin is the most common cause of the malfunction of a key fob. Other causes include water damages as well as a defective module and interference signals.
Dead Coin Battery
Replace the battery if your key fob has failed. Use a brand new button battery with exactly the same size, voltage and specifications as the original.
If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned before being used again. The best solution is to use a paper towel soaked with isopropyl, or electronic cleaner.
If the key fob is not working despite being not exposed to water it could be due a malfunction in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob through an OBDII scan could assist in these situations.
Water Damage
You might have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It is usually possible to repair it by removing the batteries and cleaning the circuit board with ruby alcohol. It is best to let the circuit board completely dry before installing the battery.
There could be a problem with the module in the event that your key fob stops working after replacing the battery or reprogramming. You can find instructions for reprogramming most vehicles' remote keys on YouTube, or consult the owner's manual. You can also try resetting the car's onboard computer with the OBDII scan tool.
Faulty Receiver Module
The key fob contains the chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This can be caused by dropping the key fob, or by exposure to water. If the key fob you have purchased has stopped working due to water exposure or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropylethanol.
If the key fob is still unable to not respond even after cleaning it it is likely that the module is faulty and needs to be replaced. A faulty receiver can also cause the key to cease to function. This is usually caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip inside the key fob is an important part of the anti-theft system in your vehicle. It transmits a message the immobiliser inside your car to inform it whether the key is genuine. Your car won't start if the chip is damaged.
A faulty chip may also be caused by interference from other objects, bad weather or transmitters in the vicinity of your vehicle. In this case you'll require a new key fob.
Contacts for the battery that are defective
The battery contacts on the fob's battery can be damaged through heavy use. If they are damaged or bent, the fob won't send any signals to the receiver modules in the car.
Modern fobs are equipped with rubber seals that block out water. Submerging them in water even if it's only small splash or drizzle, can damage the chip's electronic circuit.
The key fob is equipped with a chip that communicates with the vehicle's immobilizer to allow it to start it. fiat 500 key fob replacement uses the old red keys that were used in older vehicles or the crypto coding system in modern vehicles. If this chip is faulty and needs to be replaced.
The 12 Volt Battery is faulty
A faulty battery may cause the key fob to function. The car's computer won't recognize the remote if this occurs.
Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly the time is now to replace it.
Install an electrical charge for a few moments on the battery to check its capacity. This will eliminate one percent of the surface charges. Then, measure the voltage again. The better the battery's capacity is, the longer it will keep its voltage. The ideal scenario is to keep it at 12 volts or less for several minutes.
Problems with Radio Signal
This is the most typical reason for the key fob not sending signals to the car. The battery can be replaced to fix this issue. It is however important to buy a new battery that has the same voltage and size as the original.
Fobs take a lot of abuse, but they're not impervious to destruction. The battery buttons and contacts are delicate and can be bent or broken by rough use.
A signal may also be impacted by other objects or transmitters that operate on the same frequency. A light-control panel in your home, for instance can interfere with key fobs that use the same frequency. This could affect the remote control of your car.
Faulty OBDII Scan Tool
There are many reasons why a scan tool could not work. Certain are more complicated than others.
Professional scan tools enable a mechanic observe the car's network, and run various self-tests. These tools can save you a lot of time, but they are costly and are out of reach for the majority of DIYers.
If your OBD2 scan tool doesn't turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition there is a chance that a fuse has ruptured. This is the most frequent cause of scan tool failure. It is typically easy to fix the issue by replacing the blown fuse.
