fiat replacement car keys Panda keyfobs are equipped with a transponder that sends an indication from the fob to the fiat car key replacement that allows it to unlock doors or turn on the motor. However, the fob may not function due to a variety of reasons.
A dead battery for the coin is the most common reason for the malfunction of a key fob. Other causes are water damage, a faulty module, and interference signals.
Dead Coin Battery
Replace the battery in case your key fob has gone out of service. Use a button cell battery that has the same voltage, size and specification as your old one.
If the key fob was exposed to water, such as a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. The best method is to use a paper towel that has been soaked in isopropyl, or electronic cleaner.
If the key fob has not been exposed to water but it is still not working it could be a problem with the receiver module or an internal electronic chip. In these situations you can reprogramme the key fob using an OBDII scanner can assist.
Water Damage
You might have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It is usually possible to restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob dry completely before installing a new battery.
If your key fob isn't working even after replacing the battery and programming it again, you might have a malfunctioning receiver module. There are reprogramming guidelines for most vehicles' remote replacement fiat 500 key fobs on YouTube or in the owner's manual. You can also reset your car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob has a chip which communicates with the vehicle's system. If this chip becomes damaged, it can no longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or by water exposure. If the key fob stopped working after water exposure it may be possible to repair it by cleaning the chip with isopropyl alcohol, or electronic cleaner.
If the key fob does not respond even after cleaning it it is likely that the module is faulty and needs to be replaced. A damaged receiver can cause the key to not work. This is usually caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip in the key fob is an essential component of the anti-theft system in your car. It sends a signal the immobiliser unit in your car to inform it whether or not the fiat ducato key fob programming is legitimate. If the chip is damaged or broken, the car will not start.
A damaged chip could be caused by interference from other objects, bad weather or transmitters near your vehicle. In this instance you'll need a new key fob.
Faulty Battery Contacts
The battery contacts on the key fob could be damaged by heavy usage. If they're bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.
Modern fobs feature rubber seals that keep out water. A splash of water or a light rain is acceptable however, submerging them in saltwater could harm the electronic chip.
The key fob has an electronic chip that communicates with the vehicle's immobilizer to allow it to begin it. The system utilizes the old red keys in older vehicles as well as the cryptocoding system that is used in newer cars. If the chip is defective it will have to be replaced.
A faulty 12 Volt battery
A defective battery can cause the key fob not to work. When this occurs, the car's computer system will not be able to recognize that the remote is within the vehicle.
Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly it is time to replace the battery.
To test the battery's capacity, place an electrical load on it for a few minutes. This will remove one percent of the surface charges. Then, measure the voltage again. The better the battery's capacity, the longer it can maintain its voltage. It should be close to 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most frequent cause of a key fob that ceases to send signals to the car. This issue can be resolved by replacing the battery. It is important to buy a battery that has the same dimensions and voltage as the original.
Fobs take a lot of punishment, and aren't impervious to destruction. The battery buttons and contacts are brittle and can be bent or damaged by rough usage.
Other transmitters or objects operating on the same frequency can disrupt the signal. For example, a light-control panel close to your home can transmit interference on the same frequency as key fobs use. This could affect the remote control of your car.
Problems with OBDII Scan Tool
There are a variety of reasons why scanners don't function. Certain are more complicated than others.
Professional scan tools enable mechanics to examine the car's systems and perform a variety of self-tests. These tools can save a lot of time, but are expensive and not accessible to the majority of DIYers.
If your OBD2 scan tool won't power on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape, it's likely that a fuse has been blown. This is among the most frequent causes of failures in the scan tool. It is generally easy to fix the issue by replacing the fuse that was blown.
