11 "Faux Pas" You're Actually Able To Use With Your Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends signals to your car to open the doors and start the engine. The fob can stop functioning due to a variety reasons.
The most frequent cause of key fob failure is the battery of the coin is dead. Other reasons include water damage, malfunctioning receiver modules and signal interference.
Dead Coin Battery
If your key fob battery has died, the first thing to do is replace it. Use a new button cell battery that has identical in size, voltage, and specification as the previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned prior to being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner can work wonders.
If the key fob isn't working even though it is not exposed to water, it could be due a malfunction in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob by using an OBDII scan may help in these cases.
Water Damage
You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's usually possible to get it back in working order by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It's best to allow the device to completely dry before installing batteries.
If your key fob stopped working even after replacing the battery and programming it again, you might have a faulty receiver module. You can find the instructions for reprograming the majority of remote keys on YouTube or refer to the owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.
Faulty Receiver Module
The key fob's chip is an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. This could be due to dropping the key fob, or by water exposure. If the key fob is not working after exposure to water, it is possible to repair it by cleaning the chip with isopropyl alcohol or an electronic cleaner.
If the key fob does not respond to cleaning, it's possible that the receiver module has an issue and must 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 inside your key fob is a vital function in the anti-theft security system of your car. It sends a signal to the immobiliser unit inside your car to inform it whether or not the key is genuine. If the chip is damaged or damaged, your car won't start.
A damaged chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this situation, a new fob will be needed.
Contacts for the battery that are damaged
The battery contacts on a key fob can be damaged through heavy use. If they are bent, or broken, the fob won't send any signals to receiver modules inside the vehicle.
Modern fobs come with rubber seals that keep out water. In the event of submerging them in water, even if just the slightest splash or drizzle, can damage the chip's electronic components.
replacement key fiat 500 has an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. The system is based on the old red keys that were used in older vehicles as well as the cryptocoding system used in the latest vehicles. If the chip is not working properly, it will need to be replaced.
A faulty 12 Volt battery
A malfunctioning battery could cause the remote to cease working. When this happens the car's computer will not recognize that the remote is in the vehicle.
Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly then it's time to replace the battery.
To test the battery's capacity, place an electrical load on it for a couple of minutes. This will eliminate approximately 1 percent of the charge on the surface. Then, you can measure the voltage again. The longer the battery is able to hold its voltage more effectively, the greater its capacity. The ideal is to keep it close to 12 volts over several minutes.
The radio signal is not working properly. Radio Signal
This is the main cause of a key fob that stops sending signals to the car. The battery is able to be replaced to resolve this problem. It is essential to purchase a battery that has the same voltage and dimensions as the original.
Fobs are not indestructible and can be damaged by a lot. The battery buttons and the contacts are fragile which means they could be bent or broken with rough usage.
Other transmitters or objects operating on the same frequency can disrupt the signal. For example, a light-control panel that is near your home could send interference over the same bandwidth that key fobs utilize. This could affect the remote control of your car.
Afflicted OBDII Scan Tool
There are many reasons why a scanner could not work. Certain are more complicated than others.
Professional scan tools enable mechanics to examine the car's systems and perform a variety of self-tests. These are great time savers, but they are also extremely expensive, out of the reach of most DIYers.
If your OBD2 scan tool isn't turning on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK the fuse could have failed. This is one of the most common causes of failures in the scan tool. The easiest fix is to replace the fuse that has been blown.
