fiat panda key fob replacement Panda key fobs contain transponder chips that send an alert to your car to open the doors or start the engine. However, the fob can stop working for several reasons.
The most common cause of key fob malfunction is an inoperable coin battery. Other causes are water damage, an inoperative receiver module and signal interference.
Dead Coin Battery
Replace the battery if the key fob is dead. Choose a new button battery that is exactly the same size, voltage, and specification as the original.
If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will be the solution.
If the key fob doesn't working even though it is not exposed to water it could be due to a glitch in the receiver module or an internal electronic chip. In these instances you can reprogramme the key fob with an OBDII scanner could assist.
Water Damage
You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is best to allow the device to completely dry before installing batteries.
You could have a damaged module when your key fob ceases working after replacing the battery or changing the programming. You can find the instructions for changing the programming of most remote keys on YouTube or refer to your owner's manual. You can also reset the computer of your car using the OBDII scanner tool.
Faulty Receiver Module
The key fob's chip is the chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. A key fob falling off can result in this, as can water exposure. If the key fob is not working after water exposure it may be possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.
However, if the key fob continues to not respond following cleaning, there is a good chance that the component is damaged and must be replaced. A defective receiver module could also cause the remote control key to cease functioning. This is typically caused by electromagnetic interference.
Faulty electronic chip
The chip that is embedded in the key fob is an important part of the anti-theft system in your vehicle. It transmits a signal to the immobiliser unit of your vehicle to tell it whether or not the key is valid. If the chip is damaged or broken, your vehicle won't start.
A faulty chip may also be caused by interference from objects, bad weather or transmitters near your vehicle. In this situation the replacement fob will be needed.
Contacts with the battery may be damaged.
The battery contacts on a key fob can be damaged through heavy use. If they are damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.
Modern fobs feature rubber seals that block out water. A splash of water or light rain is acceptable However, submerging them in saltwater may cause damage to the chip's electronic components.
The key fob houses an electronic chip that communicates with the vehicle's immobilizer system in order to activate it. This system makes use of cryptocoding systems in newer vehicles as well as the traditional red key system in older models. This chip needs to be changed if it is malfunctioning.
The 12 Volt Battery is faulty
A malfunctioning battery could cause the fiat doblo key fob not to function. If this happens, the car's computer system cannot recognize that the remote is within the vehicle.
Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly then it's time to replace the battery.
Place an electrical load for a short period of time on the battery to gauge its capacity. This will eliminate 1% of the surface charges. Then, you can measure the voltage again. The better the battery's capacity, the longer it can maintain its voltage. The ideal scenario is to keep it close to 12 volts for several minutes.
Faulty Radio Signal
This is the most common reason behind a key fob that stops sending signals to the car. This issue can be fixed by replacing the battery. It is however important to buy a new battery with the same voltage and size as the original.
Fobs can take a lot abuse, but they're not impervious to destruction. The battery contacts and buttons are delicate and are susceptible to being bent or broken by rough usage.
A signal may also be interrupted by other objects or transmitters which use the same frequency. For instance, a lighting control panel in your home could transmit interference on the same bandwidth that key fobs use. This can interfere with the remote control of your car.
Faulty OBDII Scan Tool
There are many reasons why a scan tool could not work. Certain are more complicated than others.
Professional scan tools enable mechanics to observe the car's network, and run various self-tests. These tools can save a lot of time, but they're expensive and out of reach for most DIYers.
If your OBD2 scan tool doesn't turn on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's possible that a fuse has blown. This is among the most frequent causes of failures in the scan tool. The most straightforward fix is to replace the fuse that has been blown.
