20 Resources To Make You More Efficient With Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder, which sends a signal from the fob to the car in order to unlock doors or start the motor. However, the key fob may not function due to a variety of reasons.
A dead coin battery is the most common cause of the malfunction of a key fob. Other causes include water damage or a malfunctioning module and interference signals.
Dead Coin Battery
Replace the battery if the key fob has gone out of service. Choose fiat ducato key that is the same voltage, size and specifications as the previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned prior to being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can help.
If the key fob doesn't working despite not being exposed to water, it could be due to a glitch in the receiver module, or even in the internal electronic chip. In these situations it is possible to re-programme the key fob using an OBDII scanner may assist.
Water Damage
It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually get it working again by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to let the circuit board completely dry before installing batteries.
If your key fob has stopped working even after replacing the battery and changing the program, you could have a problem with the receiver module. You can find instructions for reprograming the majority of remote keys on YouTube or consult your owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.
Faulty Receiver Module
The key fob has an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob can cause this, as well as water exposure. If the key fob stops working after water exposure it is possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.
However, if the key fob continues to not respond after cleaning it, you can be sure that the module is faulty and must be replaced. A faulty receiver can also cause the key to cease to function. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The chip that is embedded in your key fob is a vital component of the anti-theft systems in your car. It transmits a message the immobiliser in your car to tell it that the key is valid. Your car won't start when the chip is damaged.
A malfunctioning chip can be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this case it is likely that a new fob would be needed.
Contacts for the battery that are damaged
The battery contacts on a key fob are very fragile and are susceptible to damage with hard usage. If they're bent, or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.
Modern fobs are made with rubber seals in order to keep out water. A splash of water or a light rain is fine however, submerging them in saltwater could harm the electronic chip.
The key fob comes with an embedded chip that communicates to the immobilizer system of the vehicle to begin it. It uses the old red keys in older vehicles, or the crypto coding system in modern vehicles. This chip needs to be changed if it is faulty.
Problems with 12 Volt Batteries
A faulty battery can cause the key fob to cease working. If this happens, the car's computer system will not recognize that the remote is in the vehicle.
Before you replace the battery, test it with an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly then it's time to replace it.
Put an electrical load for a short period of time on the battery to check its capacity. This will take away 1% of the surface charges. Then, you can measure the voltage again. The better the battery's capacity is, the longer it will maintain its voltage. Ideally, it will remain close to 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the main cause of a key fob that stops sending signals to the car. The battery can be replaced to fix this issue. But, it is essential to purchase a battery with the same voltage and size as the original.
The buttons are not impervious to destruction and are susceptible to damage. Contacts and buttons on batteries can be damaged through rough handling.
Other transmitters or objects operating on the same frequency can also disrupt the signal. A light control panel in your home, for example can interfere with key fobs which use the same frequency. This could affect the remote control of your car.
Incorrect OBDII scan tool
There are many reasons why a scanner tool may not perform. Some are more complex than others.
Professional scan tools allow mechanics to monitor the car's network and conduct a variety self-tests. These tools can save a lot of time, but they're expensive and not accessible to the majority of DIYers.
If your OBD2 scanner doesn't work make sure you check 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 ruptured. This is one of the most common causes of failures in the scan tool. The simple fix is usually to replace the fuse which has blown.
