fiat 500 duplicate key Panda key fobs contain a transponder chip that sends a signal to your car to open the doors or start the engine. However, the key fob may stop working due to a variety of causes.
The most common reason for key fob failure is the battery of the coin is dead. Other causes include water damage or a damaged module and interference signals.
Dead Coin Battery
Replace the battery if your key fob has gone out of service. Choose a button battery that has the same voltage, size, and specifications as your previous one.
If the key fob has been exposed to water, such as a splash of rain or salt water at the beach, it will need to be cleaned before it can be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will do the trick.
If the key fob hasn't been exposed to water but remains inoperable it could be because of a problem with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob using an OBDII scanner can aid.
Water Damage
There could be water damage if your fiat 500x key fob programming fob was submerged in a pool, puddle or washing machine. It is usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is a good idea to let the fob dry completely before installing a new battery.
It could be that you have a defective module if your key fob stops working after replacing the battery or changing the programming. You can find the instructions for changing the programming of most remote keys on YouTube or refer to your owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.
Faulty Receiver Module
The key fob's chip is a chip which communicates with the vehicle's system. If the chip is damaged, it will no longer be able to send or receive signals to the vehicle. This can be caused by dropping the key fob, or due to exposure to water. If your key fob stopped functioning due to water exposure it is possible fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.
If the key fob is still unable to not respond following cleaning, you can be sure that the module is faulty and will require to be replaced. A faulty receiver can also cause the key to not work. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip in your key fob plays an important role in the anti-theft security system in your car. It transmits a message to the immobiliser inside your car that tells it whether the key is legitimate. If the chip is damaged or broken, the car will not start.
A defective chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this situation, you will need a new fiat 500 key fob 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 bent, or damaged, the fob will not send any signals to the receiver modules inside the vehicle.
Modern fobs are equipped with rubber seals that block out water. A splash of water or a light rain should be fine However, submerging them in saltwater can harm the electronic chip.
The key fob is equipped with chips that communicate with the vehicle's immobilizer to allow it to start it. The system uses the red keys of older vehicles as well as the cryptocoding system found in the latest vehicles. If the chip is damaged it will have to be replaced.
A faulty 12 Volt battery
A faulty battery can cause the key fob to cease to function. The car's system will not recognize the remote if this happens.
Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly it's time to change it.
To test a battery's capacity put an electrical load on it for a few minutes. This will take away 1percent of the charges. After that, measure the voltage. The greater the battery's capacity is, the longer it will keep its voltage. Ideal is to hold close to 12 volts during several minutes.
Radio Signal Faulty Radio Signal
This is the main reason behind a key fob that stops sending signals to the car. The battery can be replaced to solve this problem. However, it is crucial to choose a battery that has the same voltage and size as the original one.
Fobs endure a lot of abuse, but they're not impervious to destruction. Contacts and buttons on batteries can be damaged by rough handling.
Other transmitters or objects operating on the same frequency could also disrupt a signal. For instance, a light-control panel that is near your home could send interference on the same bandwidth that key fobs utilize. This could affect the remote control of your car.
Incorrect OBDII scan tool
There are a number of reasons why a scanner could not work. Some are more complicated than others.
Professional scan tools allow mechanics to look over the car's networks and conduct a variety self-tests. These can be real time savers but they can also be very expensive, and out of the budget of many DIYers.
If your OBD2 scan tool fails to turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape the chances are that a fuse has failed. This is among the most common causes of scan tool failure. The easiest solution is to replace the fuse that has been blown.
