fiat 500 car key Panda key fobs contain transponder chips that send an alert to your car to unlock the doors or start the engine. However, the key fob may be inoperable due to various reasons.
The most common reason for key fob malfunction is a dead coin battery. Other causes are water damage, a faulty receiver module, and signal interference.
Dead Coin Battery
If your key fob battery has gone out of service, the first thing to do is replace it. Use a brand new button battery that is identical in size, voltage, and specification like the previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned before being used again. A paper towel soaked in alcohol or electronic cleaner will be the solution.
If the key fob has not been exposed to water, but isn't working it could be an issue with the receiver module or an internal electronic chip. In these instances it is possible that reprogramming the key fob using an OBDII scanner can help.
Water Damage
If your key fob took an immersion in the puddle or pool, or taken a trip down the wash machine, you could be suffering some water damage. You can usually be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to let the circuit board completely dry before installing a battery.
If your key fob isn't working even after replacing the battery and reconfiguring it, you may have a defective receiver module. You can find reprogramming procedures for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You could also try resetting the car's onboard computer using the OBDII scan tool.
Faulty Receiver Module
The key fob has a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. The key fob being dropped can result in this, as can exposure to water. If the key fob stops working after exposure to water it may be possible to fix it by cleaning the chip with isopropyl ethanol or electronic cleaner.
If the key fob does not respond after cleaning it, then it is likely that the module is faulty and needs to be replaced. A malfunctioning receiver could cause the key to not work. This is typically caused by electromagnetic interference.
A malfunctioning electronic chip
The electronic chip inside your key fob is an essential component of the anti-theft systems in your car. It transmits a message the immobiliser in your car to tell it whether the key is legitimate. If the chip is damaged or broken, your lost car key fiat will not start.
A damaged chip could be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this instance you'll need an entirely new key fob.
Contacts of the battery may be damaged.
The battery contacts of a key fob can be damaged due to heavy use. If they're broken or bent, the fob will not send any signals to the receiver modules inside the car.
Modern fobs are designed with rubber seals that keep out water. Submerging them in water, even if it's just a light drizzle or splash could harm the chip's electronic circuit.
The key fob has chips that communicate with the vehicle's immobilizer system to start it. The system relies on cryptocoding systems in modern vehicles as well as the traditional red fiat ducato key fob system used in older models. This chip needs to be replaced if faulty.
Poor 12 Volt Battery
A faulty battery can cause the Spare key for fiat 500 fob to cease to function. The car's computer won't recognize the remote when this occurs.
Test the battery using the help of 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.
Set an electrical load for a few seconds on the battery to gauge its capacity. This will take away 1percent of the charges. After that, measure the voltage. The longer a battery is able to hold its voltage greater is its capacity. Ideal is that it stays close to 12 volts for several minutes.
Faulty Radio Signal
This is the most typical reason for the key fob not sending signals to cars. The battery could be replaced to fix this issue. It is however important to buy a new battery with the same voltage and size as the original one.
Fobs aren't indestructible and are susceptible to damage. The battery buttons and contacts are delicate which means they could be bent or damaged by rough use.
A signal may also be impacted by other objects or transmitters which use the same frequency. A light-control system in your home, for example could interfere with key fobs which use the same bandwidth. This could interfere with your car's remote control.
Afflicted OBDII scan tool
There are many reasons why scanner tools may not work. Some are more complicated than others.
Professional scan tools allow mechanics to monitor the car's network and run a range of self-tests. These tools can save you a lot of time, but are costly and out of reach for most DIYers.
If your OBD2 scanner won't turn on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's likely that a fuse has blown. This is the most typical cause of scan tool failure. It is generally easy to fix the issue by replacing the fuse that was blown.
