12 Companies That Are Leading The Way In Fiat 500 Keys

Fiat key programmer Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that sends an indication from the fob to the car in order to unlock doors or start the motor. The fob might stop working due to a variety of reasons.

The most common cause of key fob failure is the battery of the coin is dead. Other causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery in case your key fob has gone out of service. Use a brand new button battery that has exactly the same size, voltage, and specification like the previous one.

If the key fob has been 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 can be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will work wonders.

If the key fob isn't working even though it is not exposed to water, it could be due to a malfunction in the receiver module or in the internal electronic chip. In these situations you can reprogramme the key fob with an OBDII scanner may assist.

Water Damage

If your key fob has taken submerged in a pool or puddle or gone to the washing machine, you may have some water damage. It is usually possible how to get a new fiat 500 key be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the fob completely dry before installing batteries.

It could be that you have a defective module if your key fob stops working after replacing the battery or reprogramming. There are instructions for reprograming the majority of remote keys on YouTube, or consult your owner's manual. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has an electronic chip that communicates with the vehicle's system. If the chip is damaged, it will be unable to longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or through exposure to water. If your key fob isn't functioning due to exposure to water, you may be able to fix it if you clean the chip with electronic cleaner or isopropyl ethanol.

However, if the key fob still does not respond following cleaning, then it is likely that the module is defective and needs to be replaced. A malfunctioning receiver could cause the key to not work. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in your key fob is a vital element of the anti-theft device in your car. It sends a signal the immobiliser unit inside your car to determine whether the key is valid. If the chip is damaged or broken, your vehicle will not start.

A malfunctioning chip could be caused by interference signals from other objects like bad weather conditions or transmitters on the same frequency in close proximity to your car. In this situation an upgrade to the fob will be required.

Contacts of the battery may be damaged.

The battery contacts on a key fob are very delicate and may be damaged with hard usage. If they're bent, or damaged, the fob will not transmit any signals to receiver modules in the vehicle.

Modern fobs come with rubber seals that keep out water. Submerging them in water even if just the slightest splash or drizzle could damage the chip's electronic components.

The key fob is equipped with chips that communicate with the vehicle's immobilizer to allow it to start it. It uses the old red keys in older vehicles or the cryptocoding system used in modern vehicles. The chip must be changed if it is faulty.

A faulty 12 Volt battery

A malfunctioning battery could cause the key fob to function. When this occurs, the car's computer system cannot recognize that the remote is within the vehicle.

Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly, it's time to replace it.

To test the battery's power, place an electrical load on it for a couple of minutes. This will eliminate approximately 1% of the charge on the surface. Then, you can measure the voltage. The longer a battery can keep its voltage steady and the higher its capacity. Ideally, it will remain at 12 volts or less for several minutes.

Faulty Radio Signal

This is the main reason behind a key fob that stops sending signals to the car. This issue can be fixed by replacing the battery. But, it is essential to purchase a battery with the same voltage and size as the original.

Fobs can take a lot abuse, but they're also not impervious to destruction. Contacts on batteries and buttons can be damaged by rough handling.

A signal can also be affected by other transmitters or objects which use the same frequency. For instance, a lighting control panel close to your home can send interference over the same bandwidth that key fobs utilize. This could interfere with the remote control of your car.

Incorrect OBDII Scan Tool

There are many reasons why a scanner tool may not function. Some are more complicated than others.

Professional scan tools permit mechanics to observe the car's networks and run a range of self-tests. These tools can save time, but they're expensive and out of reach for most DIYers.

If your OBD2 scan tool isn't turning on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the fuse could have blown. This is among the most frequent reasons for failure of the scanner. It is usually easy to fix the problem by replacing the blown fuse.
