fiat key duplication Panda keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car in order to unlock doors or turn on the motor. The fob might stop working for a variety.
The most commonly cited reason for key fob malfunction is a dead coin battery. Other causes include water damage a faulty receiver module, and signal interference.
Dead Coin Battery
If your key fob battery has failed, the initial thing to do is replace it. Use a new button cell battery with identical in size, voltage and specifications as the old one.
If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it will need to be cleaned before it is able to be used again. The best way to do this is using a paper towel soaked with isopropyl or an electronic cleaner.
If the key fob is not working despite not being exposed to water it could be due to a problem in the receiver module or in the internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner can assist.
Water Damage
If your key fob's battery has taken an immersion in the pool or puddle or gone down the wash machine, you might have some water damage. It is usually possible to be able to get it back up and running by removing 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.
If your key fob has stopped working even after replacing the battery and reconfiguring it, you may have a faulty receiver module. You can find information on reprogramming most vehicles' remote keys on YouTube or in your owner's manual. You can also reset the computer in your car with the OBDII scanner tool.
Faulty Receiver Module
The key fob is equipped with a chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob could cause this, as could exposure to water. If the key fob you have purchased has stopped functioning due to exposure to water, you may be able fix the issue if you clean the chip with electronic cleaner or isopropylethanol.
However, if the key fob does not respond after cleaning it, then it is likely that the module is faulty and must be replaced. A malfunctioning receiver could cause the key to not work. This is typically caused by electromagnetic interference.
Faulty electronic chip
The electronic chip inside your key fob plays a vital role in the anti-theft system of your vehicle. It sends a message to the immobiliser inside your car to tell it whether the key is genuine. Your car won't start in the event that the chip is damaged.
A faulty chip can also be caused by interference signals from other objects, bad weather conditions or transmitters operating on the same frequency near your vehicle. In this scenario you'll require an entirely new key fob.
Faulty Battery Contacts
The battery contacts inside a key fob are very delicate and may be damaged through repeated use. If they're bent, or broken, the fob won't transmit any signals to receiver modules inside the vehicle.
Modern fobs have rubber seals to keep out water. In the event of submerging them in water, even if it is just the slightest splash or drizzle could harm the chip's electronic components.
The key fob has chip that communicates with the immobilizer system of the vehicle in order to start it. This system makes use of cryptocoding systems in the latest vehicles, or the old red key system used in older ones. If this chip is faulty, it will need to be replaced.
Faulty 12 Volt Battery
A faulty battery can cause the remote to stop working. If this happens, the car's computer system won't recognize that the remote is inside the vehicle.
Before replacing the battery, test it by using a the voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly, it is time to replace the battery.
To test a battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away 1% of the surface charges. Then take another measurement of the voltage. The longer the battery can keep its voltage steady greater is its capacity. Ideal is that it stays close to 12 volts during several minutes.
Faulty Radio Signal
This is the most frequent cause of a key fob that stops sending signals to the car. This issue can be resolved by replacing the battery. However, it is crucial to purchase a battery that is the same voltage and size as the original one.
Fobs aren't impervious to damage and can take a lot. The battery contacts and buttons are delicate, so they can get bent or damaged from rough usage.
Other objects or transmitters using the same frequency can also interfere with a signal. For instance, a light control panel in your home could send interference on the same bandwidth that key fobs utilize. This can affect the remote control of your car.
Afflicted OBDII scan tool
There are a variety of reasons why a scanner tool may not work. Some are more complicated than others.
Professional scan tools let mechanics to monitor the car's network and perform various self-tests. They can be huge time savers, but they're also expensive and are out of the budget of many DIYers.
If your OBD2 scan tool isn't turning on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If all is fine there is a chance that a fuse has blown. This is among the most common reasons for failure of the scanner. The simple fix is usually to replace the fuse that has been blown.
