Fiat Panda Key Fob
replacement car keys fiat 500fiat ducato key Panda keyfobs are equipped with a transponder that transmits an electronic signal from the fob to the car to unlock doors or turn on the motor. The fob may stop working for a variety.
The most common reason for key fob failure is an inoperable coin battery. Other causes include water damage the receiver module is defective and signal interference.
Dead Coin Battery
Replace the battery if your key fob has failed. Choose a new button battery with exactly the same size, voltage, and specification as the old one.
If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned prior to being used again. The trick is to use a paper towel soaked with isopropyl, or electronic cleaner.
If the key fob isn't working even though it is not exposed to water it could be due to a glitch in the receiver module or internal electronic chip. In these situations you can reprogramme the key fob with an OBDII scanner might aid.
Water Damage
There could be water damage if your key fob was submerged in a pool, puddle or washing machine. It's possible to repair it by taking out the batteries and cleaning the circuit board using rubbing alcohol. It is best to let the board completely dry before putting in 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 reprogramming guidelines for most remote key fobs on YouTube or in the owner's manual. You can also reset the car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob contains a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. A
spare key for fiat 500 fob falling off can cause this, as well as water exposure. If your key fob has stopped functioning due to exposure to water or water exposure, you might be able to fix it if clean the chip using electronic cleaner or isopropylethanol.
However, if the key fob continues to not respond even after cleaning it you can be sure that the receiver module is not functioning properly and needs to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.
A defective electronic chip
The electronic chip in the key fob is an important component of the anti-theft system in your car. It sends a message to the immobiliser in your car to inform it whether the key is genuine. If the chip is damaged or broken, the car will not start.
A defective chip could be caused by interference from other objects, weather conditions or transmitters close to your vehicle. In this scenario you'll need a new key fob.
Contacts with the battery may be damaged.
The battery contacts in the key fob are fragile and are susceptible to damage through repeated 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 block out water. In the event of submerging them in water, even if it is just an occasional drizzle or splash could damage the chip's electronic components.
The key fob houses a chip that communicates with the vehicle's immobilizer system to allow it to start. It uses the red keys of older vehicles, or the cryptocoding system found in newer cars. If the chip is damaged, it will need to be replaced.
The 12 Volt Battery is faulty
A damaged battery could cause the key fob to work. If this happens, the car's computer system won't recognize that the remote is in the vehicle.
Before replacing the battery, test it with the voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly it is time to replace the battery.
To test the battery's capacity test the battery's capacity by placing an electrical load on it for a few minutes. This will take away 1percent of the surface charges. After that, measure the voltage. The higher the capacity of the battery, the longer it can keep its voltage. The ideal is to keep it close to 12 volts during several minutes.
Radio Signal Faulty Radio Signal
This is the most common reason for the key fob to stop sending signals to cars. This issue can be fixed by replacing the battery. 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 the contacts are fragile, so they can get bent or damaged from the force of.
A signal can also be affected by other objects or transmitters that use the same frequency. A light-control panel in your home, for instance, may interfere with key fobs that have the same frequency. This can interfere with the remote control of your car.
Incorrect OBDII Scan Tool
There are a number of reasons why a scan tool could not work. Some are more complicated than others.
Professional scan tools let mechanics to observe the car's network, and run various self-tests. These are real time-savers, but they can also be very expensive and are out of the range of most DIYers.
If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're all fine the fuse could have been blown. This is the most typical cause of scan tool failure. It is often simple to fix the issue by replacing the fuse that has blown.
