Do Not Forget Fiat 500 Keys: 10 Reasons Why You Do Not Need It

fiat 500 spare key cut Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip which sends an alert to your car to open the doors and start the engine. The fob can stop functioning for a variety of reasons.

A dead coin battery is the most frequent cause of malfunctioning keys. Other causes include water damage, a faulty module, and interference signals.

Dead Coin Battery

Replace the battery if the key fob has gone out of service. Use a button cell battery with the same voltage, size, and specifications as your previous one.

If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. The best solution is to use the paper towel and soak it in isopropyl or an electronic cleaner.

If the fiat ducato key fob is not working despite not being exposed water it could be due to a problem in the receiver module or in the internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner can help.

Water Damage

If your key fob has taken immersed in a pool or puddle or gone to the washing machine, you may have some water damage. It is usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the circuit board completely dry prior to installing a battery.

You may have a faulty module when your key fob ceases working after replacing the battery or updating. You can find instructions for reprograming the majority of remote keys on YouTube or refer to your owner's manual. You can also reset your computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the car's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This could be due to dropping the key fob, or through exposure to water. If the key fob you have purchased has stopped working due to water exposure or water exposure, you might be able to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob does not respond to cleaning, it is possible that the component has an issue and should be replaced. A damaged receiver module may also cause the remote control key to stop working. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The chip inside your key fob plays a crucial part in the anti-theft security system of your vehicle. It sends out a signal the immobiliser device in the vehicle to determine whether the key is in fact valid. If the chip is damaged or broken, your vehicle will not start.

A damaged chip could be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this situation an upgrade to the fob will be required.

Contacts to the battery are not working properly.

The battery contacts of the key fob could be damaged due to heavy use. If they're bent or broken the fob will not send any signals to the receiver modules in the car.

Modern fobs come with rubber seals that block out water. A splash of water or light rain should be fine but submerging them into saltwater may damage the electronic chip.

The key fob contains chip that communicates with the immobilizer system of the vehicle to begin it. It uses the old red keys in older vehicles as well as the cryptocoding system used in the latest vehicles. If the chip is damaged, it will need to be replaced.

A faulty 12 Volt battery

A malfunctioning battery could cause the key fob to function. The car's computer will not recognize the remote when this occurs.

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

Place an electrical load for a short period of time on the battery to check its capacity. This will eliminate approximately 1 percent of the charge on the surface. After that, take the voltage once more. The longer a battery can keep its voltage steady and the higher its capacity. It is ideal to maintain close to 12 volts over several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason for the key fob not sending signals to cars. This issue can be resolved by replacing the battery. But, it is essential to purchase a battery with the same voltage and size as the original.

Fobs take a lot of abuse, and they aren't indestructible. The battery buttons and contacts are brittle, so they can get bent or broken by rough usage.

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

Afflicted OBDII scan tool

There are many reasons scanners may not work. Some are more complex than others.

Professional scan tools allow a mechanic to monitor the car's network and run a range of self-tests. These tools can save a lot of time, but are costly and out of reach for the majority of DIYers.

If your OBD2 scan tool won't power on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the chances are that a fuse has blown. This is the most common reason for a scan tool to fail. The simple fix is usually to replace the blown fuse.
