12 Companies Leading The Way In Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car to unlock doors or turn on the motor. The fob may stop working due to a variety of reasons.
A dead coin battery is the most frequent reason for a key fob malfunction. Other causes are water damage, a faulty receiver module and signal interference.
Dead Coin Battery
If your key fob battery is dead, the first step is to replace it. Choose a button battery with the same voltage, size and specifications as the old one.
If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned prior to using it again. A paper towel soaked with isopropyl alcohol or electronic cleaner will help.
If the key fob doesn't working despite not being exposed to water it could be due to a malfunction in the receiver module or internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner can help.
Water Damage
You might have water damage to your key fob if it was submerged in a puddle, pool or washing machine. You can usually restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the circuit board completely dry before installing a battery.
If your key fob has stopped working even after replacing the battery and reprogramming it, you may have a problem with the receiver module. You can find the instructions for reprogramming most vehicles' remote keys on YouTube or refer to your owner's manual. You can also try resetting the car's onboard computer with the OBDII scan tool.
Faulty Receiver Module
The key fob is equipped with the chip that communicates with the car's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or due to exposure to water. If your key fob has stopped working due to water exposure it is possible to fix it if clean the chip with electronic cleaner or isopropyl alcohol.
If the key fob won't respond to cleaning, it is likely that the module is in an issue and should be replaced. A malfunctioning receiver could cause the key to stop working. This usually happens due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip in the key fob is an important component of the anti-theft system in your vehicle. It sends a message to the immobiliser in your car that tells it if the key is valid. The car will not start if the chip is damaged.
A malfunctioning chip could be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency close to your car. In this situation you'll need a new key fob.
Contacts for the battery that are damaged
The battery contacts of a key fob can be damaged through heavy use. If they are bent, or broken, the fob won't send any signals to receiver modules in the vehicle.
Modern fobs are equipped with rubber seals to keep out water. Submerging them in water, even if it's only an occasional drizzle or splash can harm the electronic chip.
The key fob contains an electronic chip that communicates with the immobilizer system of the vehicle to start it. This system makes use of cryptocoding systems in newer vehicles as well as the traditional red key system for older models. If the chip is damaged and needs to be replaced.
Problems with 12 Volt Batteries
A defective battery can cause the key fob not to work. The car's computer won't recognize the remote when this occurs.
Test the battery with a voltmeter before replacing it to determine its capacity. fiat ducato replacement key charged battery will read 12.6 volts. If the reading drops significantly it is time to replace the battery.
To test the battery's power put an electrical load on it for a couple of minutes. This will take away 1% of the surface charges. Then, measure the voltage again. The longer the battery is able to hold its voltage greater is its capacity. Ideal is to hold at or near 12 volts for several minutes.
Radio Signal Faulty Radio Signal
This is the main reason for a keyfob that stops sending signals to the car. The battery can be replaced to solve this problem. It is important to buy an identical battery voltage and dimensions as the original.
Fobs are subject to a lot of abuse, but they're also not indestructible. The battery contacts and buttons could be damaged by rough handling.
Other transmitters or objects that use the same frequency could also disrupt the signal. A light-control system in your home, for example, may interfere with key fobs which use the same bandwidth. This can interfere with the remote control in your car.
Afflicted OBDII scan tool
There are many reasons why a scan tool could not function. 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 time, but they are costly and out of reach for the majority of DIYers.
If your OBD2 scanner won't start make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK there is a chance that a fuse has blown. This is the main cause of scan tool failure. It is often easy to fix the issue by replacing the blown fuse.
