15 Unquestionable Reasons To Love Fiat 500 Keys
Fiat Panda Key Fob Replacement


Fiat Panda key fobs contain transponder chips that send an alert to your car to open the doors or start the engine. However, the fob may stop working for several reasons.

The most frequent cause of key fob malfunction is a dead coin battery. Other causes include water damage an inoperative receiver module and signal interference.

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 battery that has the same voltage, size, and specification as your old one.

If the key fob has been exposed to water, for example a splash of rain or salt water at the beach, it will have to be cleaned before it can be used again. A paper towel soaked in alcohol or electronic cleaner will work wonders.

If the key fob hasn't been exposed to water but it is still not working it could be due to an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan could aid in these situations.

Water Damage

If your key fob took a bath in the puddle or pool or walked to the washing machine, you could be suffering some water damage. It's usually possible to get it working again by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to let the board completely dry prior to installing batteries.

You could have a damaged module in the event that your remote stops working after replacing the battery or replacing it with. There are reprogramming guidelines for most remote key fobs on YouTube or in your owner's guide. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with a chip that 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 result in this, as can water exposure. If the key fob has stopped working after water exposure it may be possible to repair it by cleaning the chip with isopropyl alcohol or an electronic cleaner.

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

Faulty electronic chip

The electronic chip in your key fob is a crucial component of the anti-theft system in your car. It transmits a message to the immobiliser inside your car that tells it whether the key is genuine. If the chip is damaged or broken, the car will not start.

A damaged chip could be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this instance, you will need a new key fob.

Contacts with the battery may be damaged.

The battery contacts of the key fob are fragile and are susceptible to damage by repeated use. If they're bent or damaged, the fob will not send any signals to the receiver modules inside the vehicle.

Modern fobs are made with rubber seals to keep out water. A splash of water or light rain is acceptable but submerging them into saltwater could cause damage to the electronic chip.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. This system utilizes cryptocoding systems in newer vehicles, or the old red key system used in older models. This chip will need to be replaced if damaged.

The 12 Volt Battery is faulty

A damaged battery can cause the remote to stop working. The car's computer will not recognize the remote when this happens.

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 decreases significantly then it's time to replace the battery.

To test the battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away 1percent of the charges. Then, you can measure the voltage. The longer the battery can hold its voltage and the higher its capacity. Ideally, it will remain close to 12 volts several minutes.

like it with Radio Signal

This is the most common reason for a keyfob that stops sending signals to the car. This issue can be fixed by replacing the battery. It is however important to select a replacement battery that has the same voltage and size as the original one.

Fobs aren't indestructible and can be damaged by a lot. The battery buttons and contacts are delicate, so they can get bent or broken by the force of.

The signal could also be affected by other transmitters or objects which use the same frequency. For instance, a lighting control panel near your home may transmit interference on the same frequency that key fobs utilize. This can interfere with the remote control of your car.

Incorrect OBDII scan tool

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

Professional scan tools let mechanics to look over the car's network and run various self-tests. These can be real time savers but they can be expensive, and beyond the range of most DIYers.

If your OBD2 scanner won't turn on Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine, a fuse may have ruptured. This is one of the most common causes of failures in the scan tool. It is typically simple to fix the issue by replacing the fuse that has blown.
