15 Terms That Everyone In The Fiat 500 Keys Industry Should Know

Fiat Panda Key Fob Replacement

fiat stilo key Panda key fobs contain a transponder chip which sends the signal to your vehicle to open the doors or start the engine. However, the fob may be inoperable due to various reasons.

The most common reason for key fob malfunction is an inoperable coin battery. Other reasons include water damage, an inoperative receiver module and signal interference.

Dead Coin Battery

If your key fob battery has failed, the initial thing to do is replace it. Make use of a new button battery that has the same size, voltage, and specification as the old one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or fiat Panda key fob electronic cleaner will be the solution.

If the key fob hasn't been exposed to water but it is still not working it could be due to a problem with the receiver module or an internal electronic chip. In these instances it is possible that reprogramming the key fob with an OBDII scanner may help.

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It is usually possible to restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is best to allow the device to completely dry prior to installing the battery.

There could be a problem with the module in the event that your remote stops working after replacing the battery or updating. You can find information on the reprogramming of most remote keys on YouTube or consult your owner's manual. You could also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob can cause this, as well as exposure to water. If your key fob stopped functioning due to water exposure or water exposure, you might be able fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob continues to not respond after cleaning it then it is likely that the component is damaged and will need to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob is a vital part of the anti-theft system in your vehicle. It sends out a signal the immobiliser unit of your car to determine whether the key is genuine. If the chip is damaged or damaged, your car will not start.

A defective chip could be caused by interference from objects, bad weather or transmitters near your vehicle. In this case, you will need an entirely new key fob.

Faulty battery contacts

The battery contacts of a key fob are very delicate and can get damaged through repeated use. If they're bent or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs are equipped with rubber seals that keep out water. A splash of water or a light rain is fine, but submerging them in salt water could harm the chip's electronic components.

The key fob contains chips that communicate with the vehicle's immobilizer system in order to start it. The system relies on cryptocoding systems in newer vehicles and the older red key system for older models. If this chip is faulty and needs to be replaced.

A faulty 12 Volt battery

A damaged battery can cause the fiat key replacement fob to cease working. The car's system will not recognize the remote when this happens.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls dramatically it is time to replace the battery.

To determine the capacity of a battery, place an electrical load on it for a couple of minutes. This will take away approximately 1 percent of the charge on the surface. Then take another measurement of the voltage. The longer the battery can keep its voltage steady more effectively, the greater its capacity. The ideal is to keep it close to 12 volts during several minutes.

Problems with Radio Signal

This is the most typical reason for the key fob to stop sending signals to vehicles. This issue can be fixed by replacing the battery. It is however important to select a replacement fiat 500 key battery that is the same voltage and size as the original.

Fobs are not indestructible and are susceptible to damage. The battery buttons and contacts are delicate and can be bent or damaged by rough use.

The signal could also be impacted by other transmitters or objects that operate on the same frequency. For example, a light-control panel that is near your home could send interference over the same bandwidth that key fobs utilize. This can interfere with the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons scanners don't work. Some are more complicated than others.

Professional scan tools enable mechanics to monitor the car's network and perform various self-tests. These are great time savers, however they are also extremely expensive, out of the budget of most 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 both are in good condition it could be that a fuse has ruptured. This is one of the most common reasons for failure of the scanner. It is usually easy to fix the problem by replacing the fuse that has blown.
