Fiat Panda key fobs contain an transponder chip that transmits a signal to your car to open the doors and start the engine. The fob could stop working for a variety of reasons.
A dead coin battery is the most common cause of the malfunction of a key fob. Other causes include water damages or a damaged module and interference signals.
Dead Coin Battery
If your key fob's battery is dead, the first step is to replace it. Use a brand new button battery that is exactly the same size, voltage and specifications as the previous one.
If the key fob has been exposed to water, for example a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will be the solution.
If the key fob doesn't working despite being not exposed to water it could be due to a malfunction in the receiver module or in the internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these instances.
Water Damage
It is possible to get water damage if your key fob was submerged in a pool, puddle or washing machine. It is usually possible to get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob dry completely before putting in a new battery.
If your key fob has stopped working, even after replacing the battery and changing the program, you could have a defective receiver module. There are instructions for reprograming the majority of remote keys on YouTube or consult the owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.
Faulty Receiver Module
The key fob has a chip that communicates with the car's system. If the chip is damaged, it will be unable to longer transmit or receive signals to the vehicle. This could be due to dropping the key fob, or due to exposure to water. If the key fob you have purchased has stopped working due to water exposure it is possible fix the issue if you clean the chip using electronic cleaner or isopropylethanol.
If the key fob doesn't respond to cleaning, it's possible that the component has issues and needs to be replaced. A faulty receiver module can also cause the remote control key to stop working. This is usually caused by electromagnetic interference.
Electronic chip that is malfunctioning
The electronic chip in your key fob plays an important part in the anti-theft security system in your car. It sends a signal the immobiliser unit inside your vehicle to tell it whether or not the key is in fact valid. The car won't start when the chip is damaged.
A faulty chip can also be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency close to your vehicle. In this instance you'll need a new key fob.
Contacts with the battery may be damaged.
The battery contacts in a key fob are very delicate and can get damaged when used for long periods of time. If they are bent, or broken, the fob won't send any signals to receiver modules inside the vehicle.
Modern fobs are equipped with rubber seals that block out water. Submerging them in water, even if just a light drizzle or splash could damage the chip's electronic components.
The key fob houses chips that communicate with the vehicle's immobilizer system to start it. This system makes use of cryptocoding systems in newer vehicles as well as the traditional red key system used in older ones. The chip must be replaced if defective.
The 12 Volt Battery is faulty
A malfunctioning battery could cause the remote to cease working. The car's computer may not recognize the remote if this happens.
Before replacing the battery, test it with a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically the time is now to replace it.
Place an electrical load for a few moments on the battery to gauge its capacity. This will remove about 1 percent of the charge on the surface. After that, measure the voltage. The longer the battery can hold its voltage, the better its capacity. Ideally, it will remain at 12 volts or less for several minutes.
Problems with Radio Signal
This is the main reason for the key fob not sending signals to vehicles. The battery can be replaced to fix this problem. However, it is important to select a replacement battery that is the same size and voltage as the original one.
Fobs endure a lot of abuse, but they're not indestructible. The battery buttons and the contacts are fragile and are susceptible to being bent or broken by rough usage.
Other transmitters or objects that use the same frequency can also interfere with the signal. For example, a light-control panel close to your home can transmit interference using the same frequency that key fobs use. This could interfere with the remote control of your car.
Incorrect OBDII scan tool
There are a variety of reasons why scanners may not perform. Certain are more complicated than others.
Professional scan tools allow a mechanic to examine the car's systems and run a variety of self-tests. These are great time-savers, but they're also expensive and are out of the budget of many DIYers.
If your OBD2 scanner doesn't work, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present, it's likely that a fuse has been blown. This is the main reason for a scan tool to fail. The simple fix is usually to replace the blown fuse.
