10 Things Competitors Learn About Fiat 500 Keys
Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that sends an indication from the fob to the car to unlock doors or start the motor. However, the fob may not function due to a variety of reasons.

A dead battery for the coin is the most frequent cause of key fob malfunctions. Other causes include water damages or a damaged module and interference signals.

Dead Coin Battery

Replace the battery in case your key fob is dead. Make use of a new button battery that has the same size, voltage 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. The best method is to use the paper towel and soak it in isopropyl, or electronic cleaner.

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 an internal electronic chip. Reprogramming the keyfob using an OBDII scan can aid in these situations.

Water Damage

You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to restore it's functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the circuit board completely dry before putting in a battery.

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

Faulty Receiver Module

The key fob has an electronic chip that communicates with the car's system. If the chip is damaged, it cannot longer transmit and receive signals to the vehicle. This could be due to dropping the key fob, or by exposure to water. If the key fob has stopped working after exposure to water it may be possible to fix the issue by cleaning the chip using isopropyl alcohol or an electronic cleaner.

If the key fob is still unable to not respond even after cleaning it there is a good chance that the component is damaged and will need to be replaced. A faulty receiver can also cause the key to stop working. This is usually caused by electromagnetic interference.

A defective electronic chip

The chip inside your key fob plays an important role in the anti-theft security system of your car. It transmits a signal to the immobiliser device in the vehicle to determine whether or not the key is valid. If the chip is damaged or damaged, your car will not start.

A faulty chip may also be caused by interference caused by objects, bad weather or transmitters close to your vehicle. In this case it is likely that a new fob would be needed.

Contacts to the battery are not working properly.

The battery contacts on a key fob are very delicate and may be damaged when used for long periods of time. If they're damaged or bent, the key fob won't send any signals to the receiver modules inside the car.

fiat ducato replacement key come with rubber seals to keep out water. A splash of water or light rain is acceptable however, submerging them in saltwater could damage the chip's electronic components.

The key fob houses a chip that communicates with the vehicle's immobilizer system in order to allow it to start. The system relies on cryptocoding systems in vehicles that are more modern as well as the traditional red key system for older ones. If the chip is defective it must be replaced.

Poor 12 Volt Battery

A defective battery can cause the key fob to cease working. When this happens, the car's computer system will not recognize that the remote is inside the vehicle.

Before replacing the battery, test it with a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading decreases 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 eliminate approximately 1% of the charge on the surface. Then take another measurement of the voltage. The longer the battery is able to hold its voltage and the higher its capacity. It is ideal to maintain close to 12 volts over several minutes.

Problems with Radio Signal

This is the main cause of a key fob that ceases to send signals to the car. The issue can be fixed by replacing the battery. It is crucial to buy a battery with the same dimensions and voltage as the original.

Fobs can take a lot abuse, but they're also not impervious to destruction. The battery buttons and contacts are brittle, so they can get bent or broken by the force of.

A signal may also be affected by other transmitters or objects that use the same frequency. A light-control panel in your home, for example can interfere with key fobs that use the same frequency. This could cause interference 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 let mechanics to monitor the car's network, and run various self-tests. These are real time savers but they can be expensive, out of the range of most 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 these are both present the chances are that a fuse has been blown. This is the most typical reason for failure of the scan tool. It is often simple to fix the issue by replacing the blown fuse.
