Fiat Panda Key Fob Replacement
fiat remote key replacement Panda keyfobs are equipped with a transponder, which sends a signal from the fob to the car to open doors or start the motor. However, the fob may stop working due to a variety of causes.
The most frequent cause of key fob malfunction is the battery of the coin is dead. Other causes include water damages or a damaged module and interference signals.
Dead Coin Battery
Replace the battery in case your key fob is dead. Use a button cell battery with the same voltage, size, and specifications as your previous one.
If the key fob has been exposed to water, such as a splash of rain or salt water at the beach, it’s going to need to be cleaned before it can be used again. The best way to do this is using a paper towel that has been soaked in isopropyl or an electronic cleaner.
If the key fob has not been exposed to water, but it is still not working it could be a problem with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner may assist.
Water Damage
If your key fob took a bath in the pool or puddle, or taken a trip down the washing machine, you may have some water damage. It’s usually possible to get it working by getting rid of the batteries and cleaning the circuit board using rubbing alcohol. It’s best to let the board completely dry before putting in the battery.
If your key fob isn’t working, even after replacing the battery and reprogramming 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 can also reset your computer of your vehicle using the OBDII scanner tool.
Faulty Receiver Module
The key fob is equipped with the chip that communicates with the vehicle’s system. This chip will stop sending and receiving signals to the car if damaged. This could be due to dropping the key fob or through exposure to water. If your key fob has stopped working due to exposure to water and you are unable to fix it if clean the chip with electronic cleaner or isopropyl alcohol.
If the key fob doesn’t respond to cleaning, it is possible that the receiver module has an issue and should be replaced. A malfunctioning receiver module could also cause the remote control key to not function. This is usually due to electromagnetic interference.
A malfunctioning electronic chip
The chip that is embedded in your key fob is an important component of the anti-theft systems in your car. It transmits a signal to the immobiliser unit in your car to determine whether or not the key is genuine. Your car won’t start in the event that the chip has been damaged.
A malfunctioning chip can 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.
Faulty battery contacts
The battery contacts on the fob’s battery can be damaged due to heavy use. If they’re bent, or broken, the fob won’t send any signals to receiver modules inside the vehicle.
Modern fobs come with rubber seals to keep out water. Submerging them in water even if it is just the slightest splash or drizzle, can damage the electronic chip.
The key fob has chips that communicate with the vehicle’s immobilizer in order to start it. The system utilizes the old red keys in older vehicles or the cryptocoding system used in modern vehicles. This chip will have to be replaced if damaged.
A faulty 12 Volt battery
A malfunctioning battery could cause the key fob to stop working. The car’s system will not recognize the remote if this occurs.
Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly the time is now to replace it.
To test a battery’s capacity to determine its capacity, put an electric load on it for a couple of minutes. This will take away approximately 1% of the surface charge. Then, reprogram test the voltage again. The longer a battery can keep its voltage steady more effectively, the greater its capacity. Ideally, it will remain at 12 volts or less for several minutes.
The radio signal is not working properly. Radio Signal
This is the most frequent reason for a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. However, it is important to purchase a battery that has the same voltage and size as the original.
Fobs take a lot of abuse, but they’re also not impervious to destruction. Battery contacts and buttons can be damaged through rough handling.
A signal can also be affected by other transmitters or objects who use the same frequency. A light-control panel in your home, for example could interfere with key fobs using the same bandwidth. This could interfere with the remote control in your car.
Incorrect OBDII scan tool
There are a variety of reasons why scanners may not work. Certain are more complicated than others.
Professional scan tools permit mechanics to observe the car’s networks and perform a variety of self-tests. These tools can save you a lot of time, but are costly and out of reach for the majority of DIYers.
If your OBD2 scanner doesn’t work examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK it could be that a fuse has blown. This is the most frequent cause of scan tool failure. The easiest solution is to replace the fuse that has been blown.
