fiat ducato key fob Panda Key Fob Replacement

fiat abarth Key Panda key fobs contain a transponder chip which sends signals to your car to open the doors and start the engine. The fob may stop working due to a variety reasons.

The most common reason for key fob malfunction is a dead coin battery. Other causes include water damage or a malfunctioning module and interference signals.

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Use a button cell that has the same voltage, size and specifications as the old one.

If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned before being used again. A paper towel soaked in alcohol or electronic cleaner can help.

If the key fob is not working despite being not exposed to water, it could be due a malfunction in the receiver module or in the internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner might help.

Water Damage

If your key fob's battery has taken an immersion in the puddle or Fiat abarth key pool or walked through the washing machine, you could be suffering some water damage. It's possible to get it working by taking out the batteries and cleaning the circuit board with ruby alcohol. It is best to let the board completely dry before installing a battery.

If your key fob stopped working even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find reprogramming instructions for most vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. This can be caused by dropping the key fob or by exposure to water. If the key fob has stopped working after water exposure it is possible to repair it by cleaning the chip using isopropyl ethanol or electronic cleaner.

However, if the key fob does not respond after cleaning it there is a good chance that the module is defective and will require to be replaced. A malfunctioning receiver could cause the key to stop working. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is a crucial component of the anti-theft systems in your vehicle. It sends a signal the immobiliser unit of your car to determine whether the key is valid. If the chip is damaged or broken, your vehicle will not start.

A faulty chip can also be caused by interference signals from other objects, bad weather conditions or Fiat Abarth Key transmitters operating on the same frequency as your vehicle. In this instance, 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 send any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals that keep out water. Submerging them in water even if it's only the slightest splash or drizzle, can damage the chip's electronic components.

The key fob contains chip that communicates with the immobilizer system of the vehicle to start it. This system utilizes cryptocoding systems in the latest vehicles as well as the traditional red key system in older models. This chip will need to be changed if it is defective.

Faulty 12 Volt Battery

A damaged battery can cause the key fob to stop working. The car's computer may not recognize the remote if this occurs.

Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly then it's time to replace the battery.

Place an electrical load for a few moments on the battery to gauge its capacity. This will take off about 1% of the surface charge. Then, you can measure the voltage once more. The longer the battery can keep its voltage steady more effectively, the greater its capacity. Ideal is to hold close to 12 volts during several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason for the key fob not sending signals to a car. The issue can be fixed by replacing the battery. It is important to buy batteries that have the same dimensions and voltage as the original.

Fobs are subject to a lot of abuse, and they aren't impervious to destruction. The battery buttons and contacts are delicate and can be bent or broken with excessive use.

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

Faulty OBDII scan tool

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

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

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present, it's likely that a fuse has been blown. This is one of the most frequent causes of scan tool failure. It is usually simple to fix the issue by replacing the blown fuse.
