20 Fun Facts About Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends the signal to your vehicle to open the doors and start the engine. The fob might stop working for a variety of reasons.
The most common reason for key fob malfunction is a dead coin battery. Other causes are water damage, the receiver module is defective, and signal interference.
Dead Coin Battery
If the battery in your key fob has gone out of service, the first step is to replace it. Use a button cell with the same voltage, size and specification as your old one.
If the key fob was exposed to water (such as saltwater or rain at the beach) it should 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 doesn't working even though it is not exposed to water, it could be due to a malfunction in the receiver module or an internal electronic chip. Reprogramming fiat ducato key programming by using an OBDII scan can assist in these situations.
Water Damage
If your key fob took an immersion in the pool or puddle or even a trip down the washing machine, you could be suffering some water damage. You can usually restore it's functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to allow the fob to dry completely before installing a new battery.
If your key fob isn't working, even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find information on reprogramming most vehicles' remote keys on YouTube or consult the owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.
Faulty Receiver Module
The key fob has a chip that communicates with the vehicle's system. If the chip is damaged, it will no longer transmit and receive signals to the vehicle. The key fob being dropped can result in this, as can exposure to water. If the key fob you have purchased has stopped working due to water exposure and you are unable fix the issue if you clean the chip with electronic cleaner or isopropyl ethanol.
If the key fob does not respond after cleaning it you can be sure that the module is defective and must be replaced. A malfunctioning receiver could cause the key to cease to function. This is typically caused by electromagnetic interference.
A defective electronic chip
The chip that is embedded in the key fob is an essential part of the anti-theft system in your vehicle. It transmits a message the immobiliser inside your car to tell it whether the key is genuine. The car won't start when the chip is damaged.
A faulty chip may also be caused by interference from other objects, weather conditions or transmitters in the vicinity of your vehicle. In this situation an upgrade to the fob will be required.
Contacts for the battery that are defective
The battery contacts of a key fob are very delicate and could be damaged with hard usage. If they're bent, or broken, the fob won't send any signals to the receiver modules inside the vehicle.
Modern fobs are constructed with rubber seals in order to keep out water. Submerging them in water, even if just the slightest splash or drizzle can harm the electronic chip.
The key fob contains the chip that connects to the vehicle's immobilizer in order to start it. This system utilizes cryptocoding systems in vehicles that are more modern and the older red key system used in older models. If the chip is not working properly and needs to be replaced.
A faulty 12 Volt battery
A defective battery can cause the key fob to function. The car's computer may not recognize the remote when this occurs.
Before you replace the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly, it is time to replace the battery.
Set an electrical load for a few moments on the battery to test its capacity. This will remove 1percent of the charges. After that, measure the voltage. The longer a battery is able to keep its voltage steady, the better its capacity. It is ideal to maintain close to 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most common reason for the key fob not sending signals to cars. The battery can be replaced to solve this issue. However, it is important to buy a new battery that is the same voltage and size as the original one.
Fobs aren't impervious to damage and can be damaged by a lot. The battery buttons and the contacts are fragile which means they could be bent or broken by rough usage.
A signal may also be disrupted by other transmitters or objects that use the same frequency. For example, a light-control panel near your home may send interference on the same frequency as key fobs use. This can affect the remote control of your car.
Afflicted OBDII scan tool
There are many reasons why a scanner tool may not function. Some are more complex than others.
Professional scan tools enable a mechanic observe the car's network, and run various self-tests. These are great time savers, however they are also extremely expensive, and out of the budget of many DIYers.
If your OBD2 scanner won't start Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK, a fuse may have been blown. This is the main cause of scan tool failure. It is generally easy to fix the problem by replacing the fuse blowing up.
