Fiat Panda key fobs contain a transponder chip that sends an alert to your car to open the doors and start the engine. The fob can stop functioning due to a variety of reasons.
The most common reason for key fob failure is the battery of the coin is dead. Other causes include water damage, the receiver module is defective and signal interference.
Dead Coin Battery
Replace the battery if your key fob has died. Use a new button cell battery that has the same voltage, size and specifications as the original.
If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it will need to be cleaned before it can be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can work wonders.
If the key fob hasn't been exposed to water, but isn't working it could be due to an issue with the receiver module or Replacement Fiat 500 Keys Derby an internal electronic chip. Reprogramming the keyfob using an OBDII scan could help in these cases.
Water Damage
There could be water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to get it back in working order by taking out the batteries and cleaning the circuit board using rubbing alcohol. It is recommended to let the board completely dry prior to installing the battery.
You could have a damaged module if your key fob stops working after replacing the battery or reprogramming. There are reprogramming guidelines for most vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's onboard computer using the OBDII scan tool.
Faulty Receiver Module
The key fob's chip is the chip that communicates with the car's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or by exposure to water. If the key fob has stopped working after exposure to water it could be possible to fix the issue by cleaning the chip with isopropyl alcohol, or electronic cleaner.
If the key fob continues to not respond even after cleaning it then it is likely that the module is defective and must be replaced. A defective receiver can cause the key to cease to function. This usually happens due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip in the key fob is an important part of the anti-theft system in your car. It sends a signal the immobiliser unit of your car to determine whether or not the key is genuine. The car won't start when the chip is damaged.
A damaged chip could be caused by interference caused by objects, bad weather or transmitters near your vehicle. In this scenario, you will need an entirely new key fob.
Contacts of the battery may be damaged.
The battery contacts of a key fob can be damaged by excessive usage. If they're broken or bent, the fob won't send any signals to the receiver modules inside the car.
Modern fobs feature rubber seals that block out water. Submerging them in water, even if it's only small splash or drizzle can harm the electronic chip.
The key fob houses an electronic chip that communicates with the vehicle's immobilizer to allow it to allow it to start. The system relies on cryptocoding systems in vehicles that are more modern, or the old red key system in older ones. This chip will need to be replaced if defective.
A faulty 12 Volt battery
A faulty battery can cause the remote to cease working. When this occurs, the car's computer system will not be able to recognize that the remote is inside the vehicle.
Before replacing the battery, test it using a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it is time to replace the battery.
Put an electrical load for a short time on the battery to test its capacity. This will take away 1percent of the charges. Then measure the voltage again. The longer a battery is able to keep its voltage steady greater is its capacity. Ideally, it will remain close to 12 volts for several minutes.
Radio Signal Faulty Radio Signal
This is the most typical cause of a key fob that ceases to send signals to the car. The battery can be replaced to fix this issue. It is crucial to buy a battery that has the same dimensions and voltage as the original.
Fobs aren't indestructible and can take a lot. The battery buttons and contacts are delicate which means they could be bent or broken with rough usage.
Other transmitters or objects using the same frequency can also interfere with a signal. For instance, a light control panel that is near your home could transmit interference using the same frequency as key fobs use. This can interfere with the remote control of your car.
Afflicted OBDII Scan Tool
There are many reasons why a scanner could not work. Some are more complicated than others.
Professional scan tools permit mechanics to look over the car's networks and run a variety of self-tests. These are great time savers, but they can be expensive, and beyond the reach of most DIYers.
If your OBD2 scan tool won't power on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's likely that a fuse is blowing. This is among the most frequent causes of failures in the scan tool. It is usually easy to fix the issue by replacing the fuse blowing up.
