Fiat Panda key fobs contain transponder chips that send a signal to your car to unlock the doors or start the engine. However, the fob could be inoperable due to various reasons.
A dead coin battery is the most common cause of malfunctioning keys. Other reasons include water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
Replace the battery if your key fob is dead. Make use of a new button battery that has exactly the same size, voltage and specifications as the previous one.
If the key fob was exposed to water, such as a splash of rain or salt water at the beach, it's going to need to be cleaned before it can be used again. The best method is to use an old towel soaked in isopropyl or an electronic cleaner.
If the key fob hasn't been exposed to water, but still does not work it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan may aid in these situations.
Water Damage
You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's usually possible to get it back to working by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's a good idea let the fob dry completely prior to installing a new battery.
If your key fob stopped working, even after replacing the battery and reprogramming it, you may have a faulty receiver module. You can find reprogramming procedures for all vehicles' remote 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 is equipped with a chip that communicates with the vehicle's system. If the chip is damaged, it can 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 the key fob stopped functioning after exposure to water, it could be possible to fix the issue by cleaning the chip with isopropyl alcohol or an electronic cleaner.
However, if the key fob is still unable to not respond after cleaning it, you can be sure that the module is faulty and will require to be replaced. A defective receiver can cause the key to not work. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob plays a vital part in the anti-theft security system in your car. It sends a signal to the immobiliser unit in the vehicle to determine whether the key is genuine. If the chip is damaged or broken, your car will not start.
A defective chip can be caused by interference signals from other objects like bad weather conditions or transmitters operating on the same frequency as your car. In this instance an upgrade to the fob will be required.
Faulty battery contacts
The battery contacts on a key fob can be damaged by excessive usage. If they're bent or broken the fob won't send any signals to the receiver modules in the car.
Modern fobs have rubber seals to keep out water. Submerging them in water, even if just an occasional drizzle or splash can harm the chip's electronic circuit.
The key fob is equipped with chip that communicates with the immobilizer system of the vehicle in order to start it. This system utilizes cryptocoding systems in modern vehicles as well as the traditional red key system in older ones. If the chip is defective and needs to be replaced.
A faulty 12 Volt battery
A faulty battery may cause the key fob to work. The car's computer will not recognize the remote when this occurs.
Before replacing the battery, test it using a the voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly it is time to replace the battery.
To test the battery's power put an electrical load on it for a few minutes. This will remove approximately 1 percent of the surface charge. Then, test the voltage once more. The greater the battery's capacity is, the longer it will maintain its voltage. The ideal is to keep it close to 12 volts over several minutes.
Radio Signal Faulty Radio Signal
This is the most frequent reason for a keyfob that stops sending signals to the car. This issue can be resolved by replacing the battery. However, it is crucial to select a replacement fiat key fob battery that is the same size and voltage as the original one.
Fobs endure a lot of abuse, but they're also not indestructible. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with the force of.
Other transmitters or objects using the same frequency could also interfere with a signal. For instance, a light control panel in your home could transmit interference using the same frequency as key fobs use. This can interfere with the remote control of your car.
Incorrect OBDII Scan Tool
There are many reasons scanner tools may not perform. Some are more complicated than others.
Professional scan tools permit mechanics to examine the car's systems and perform a variety of self-tests. These can be real time savers, however they are also extremely expensive, and beyond the budget of most DIYers.
If your OBD2 scan tool isn't turning on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's possible that a fuse has been blown. This is the most frequent reason for failures of the scanner. The easiest solution is to replace the fuse that has been blown.
