Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car to unlock doors or start the motor. The fob might stop working due to a variety of reasons.
A dead coin battery is the most frequent cause of malfunctioning keys. Other causes are water damage, the receiver module is defective, and signal interference.
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 the same size, voltage and specifications as the previous one.
If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it will need to be cleaned before it is able to be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will do the trick.
If the key fob has not been exposed to water, but isn’t working it could be because of a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan can aid in these situations.
Water Damage
If your key fob has taken a bath in the pool or Autokeysrus puddle or even a trip to the washing machine, you may have some water damage. You can usually restore it’s functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the circuit board completely dry before installing the battery.
If your key fob stopped working even after replacing the battery and reconfiguring it, you may have a problem with the receiver module. There are instructions for reprogramming most vehicles’ remote keys on YouTube, or consult the owner’s manual. You could also try resetting the car’s onboard computer using the OBDII scan tool.
Faulty Receiver Module
The key fob contains the chip that communicates with the vehicle’s system. The chip will stop sending and receiving signals to the car if damaged. A key fob falling off can cause this, as could exposure to water. If the key fob stopped functioning after exposure to water, it is possible to repair it by cleaning the chip using isopropyl alcohol, autokeysrus or electronic cleaner.
If the key fob doesn’t respond to cleaning, it’s possible that the component has an issue and should be replaced. A damaged receiver module may also cause the remote control key to stop functioning. This usually happens due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob plays a crucial part in the anti-theft security system of your car. It sends a signal to the immobiliser in your car that tells it whether the key is legitimate. Your car won’t start in the event that the chip is damaged.
A damaged chip could be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this case it is likely that a new fob would be needed.
Contacts to the battery are not working properly.
The battery contacts of the fob’s key can be damaged due to heavy use. If they are bent or broken the fob will not send any signals to the receiver modules in the car.
Modern fobs come with rubber seals that block out water. Submerging them in water even if it’s just an occasional drizzle or splash can harm the chip’s electronic circuit.
The key fob is equipped with chips that communicate with the vehicle’s immobilizer system in order to activate it. The system uses the red keys of older vehicles or the cryptocoding system found in modern vehicles. This chip will have to be replaced if it’s malfunctioning.
Faulty 12 Volt Battery
A faulty battery can cause the key fob to cease to function. The car’s system will not recognize the remote if this happens.
Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly, it’s time to replace it.
To determine the capacity of a battery to determine its capacity, put an electric load on it for a few minutes. This will eliminate 1percent of the charges. Then measure the voltage again. The better the battery’s capacity and the longer it can maintain its voltage. Ideal is to hold at or near 12 volts for several minutes.
Radio Signal Faulty Radio Signal
This is the most typical cause of a key fob that stops sending signals to the car. This problem can be solved by replacing the battery. It is crucial to purchase a battery with the same dimensions and voltage as the original.
Fobs endure a lot of abuse, but they’re also not impervious to destruction. The battery contacts and buttons are delicate and are susceptible to being bent or damaged by rough use.
Other transmitters or objects operating on the same frequency can also interfere with the signal. A light-control panel in your home, for example can interfere with key fobs which use the same bandwidth. This could interfere with the remote control of your car.
Afflicted OBDII Scan Tool
There are many reasons why a scan tool may not work. Some are more complicated than others.
Professional scan tools enable mechanics to monitor the car’s network, and run various self-tests. These tools can save a lot of time, but they are costly and not accessible to most DIYers.
If your OBD2 scanner won’t start examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it could be that a fuse has failed. This is one of the most common reasons for failure of the scanner. The most straightforward fix is to replace the fuse which has blown.
