fiat keys Replacement Panda Key Fob fiat ducato replacement key

fiat 500 key fob Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car in order to unlock doors or turn on the motor. However, the fob could stop working for several reasons.

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

Dead Coin Battery

If the battery in your key fob has died, the first thing to do is replace it. Use a new button cell battery that is the same size, voltage and specifications like the previous one.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned before using again. The best method is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water, but isn't working it could be because of a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan could aid in these situations.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is a good idea to allow the fob to dry completely prior to installing a new battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or changing the programming. You can find the instructions for reprograming the majority of remote keys on YouTube or refer to the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. A key fob falling off can cause this, as well as exposure to water. If your key fob isn't functioning due to exposure to water or water exposure, you might 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 after cleaning it it is likely that the module is faulty and needs to be replaced. A defective receiver can cause the key to not work. This usually happens due to electromagnetic interference.

Faulty electronic chip

The chip inside your key fob is a vital role in the anti-theft system of your car. It sends a signal the immobiliser unit in your vehicle to tell it whether the key is genuine. The car won't start if the chip is damaged.

A faulty chip may also be caused by interference from other objects, weather conditions or transmitters near your vehicle. In this case an upgrade to the fob will be required.

Contacts to the battery are not working properly.

The battery contacts on the fob's key can be damaged due to heavy use. If they're bent, or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.

Modern fobs have rubber seals to keep out water. A splash of water or a light rain should be fine However, submerging them in salt water could damage the chip's electronic components.

The key fob contains an electronic chip that communicates with the immobilizer system of the vehicle, allowing it to start it. It uses the old red keys in older vehicles, or the cryptocoding system that is used in newer vehicles. This chip will have to be replaced if it's faulty.

The 12 Volt Battery is faulty

A defective battery can cause the key fob to work. The car's system will not recognize the remote if this happens.

Before you replace the battery, test it by using a an voltmeter to gauge its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly then it's time to replace the battery.

Install an electrical charge for a short time on the battery to gauge its capacity. This will take off approximately 1 percent of the surface charge. Then measure the voltage again. The better the battery's capacity, the longer it can keep its voltage. It should be at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the main reason behind a key fob that stops sending signals to the car. The issue can be fixed by replacing the battery. It is however important to buy a new battery that has the same voltage and size as the original one.

Fobs aren't indestructible and can take a lot. The battery buttons and contacts are delicate and are susceptible to being bent or broken with rough usage.

Other objects or transmitters using the same frequency can interfere with a signal. A light control panel in your home, for instance could interfere with key fobs that use the same frequency. This can interfere with the remote control of your car.

Afflicted OBDII scan tool

There are many reasons why a scan tool could not work. Some are more complex than others.

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

If your OBD2 scan tool won't power on, test the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, it's likely that a fuse has been blown. This is the most common cause of scan tool failure. It is usually easy to fix the problem by replacing the fuse that was blown.
