Fiat Panda key fobs contain a transponder chip which sends a signal to your car to unlock the doors or start the engine. The fob can stop functioning for a variety.

The most frequent cause of key fob failure is the battery of the coin is dead. Other causes include water damage, a faulty module, and interference signals.

Dead Coin Battery

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

If the key fob was exposed to water, such as a splash of rain or salt water on the beach, it will have to be cleaned before it can be used again. A paper towel soaked in alcohol or electronic cleaner can be the solution.

If the key fob has not been exposed to water, but it is still not working it could be a problem with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner can help.

Water Damage

There could be water damage if your key fob was submerged in a puddle, pool or washing machine. You can usually get it working again by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's a good idea to allow the fob to dry completely prior to installing a new battery.

There could be a problem with the module if your key fob stops working after replacing the battery or changing the programming. Reprogramming instructions are available for most remote key fobs on YouTube or in your owner's guide. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with the chip that communicates the vehicle's system. If the chip is damaged, it can no longer be able to send or receive signals to the vehicle. This can be caused by dropping the key fob, or by water exposure. If the key fob stops working after water exposure it is possible to repair it by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob continues to not respond after cleaning it, it is likely that the component is damaged and will require to be replaced. A defective receiver can cause the key to not work. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key code fiat fob is a vital function in the anti-theft security system of your vehicle. It transmits a message to the immobiliser inside your car to determine that the key is valid. If the chip is damaged or broken, your vehicle won't start.

A faulty chip may also be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this situation you'll need a new key fob.

Faulty Battery Contacts

The battery contacts on the fob's battery can be damaged through heavy use. If they're bent, or broken, the fob won't send 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, but submerging them in saltwater could damage the chip's electronic components.

The key fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. The system relies on cryptocoding systems in the latest vehicles as well as the traditional red key system in older models. The chip must be replaced if it's damaged.

A faulty 12 Volt battery

A defective battery can cause the remote to cease working. If this happens, the car's computer system won't recognize that the remote is inside the vehicle.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly, it is time to replace the battery.

Set an electrical load for a short time on the battery to determine its capacity. This will remove 1% of the surface charges. Then, measure the voltage again. The higher the capacity of the battery, the longer it can maintain its voltage. The ideal scenario is to keep it at or near 12 volts for several minutes.

Problems with Radio Signal

This is the most frequent reason for keys not sending signals to a car. This problem can be solved by replacing the battery. It is important to buy a battery that has the same voltage and dimensions as the original.

The buttons are not impervious to destruction and are susceptible to damage. The battery buttons and contacts are delicate which means they could be bent or broken by excessive use.

Other transmitters or objects that use the same frequency may also interfere with the signal. For instance, a light-control panel that is near your home could transmit interference using the same bandwidth that key fobs use. This could affect the remote control of your car.

Afflicted OBDII Scan Tool

There are a number of reasons why a scan tool could not function. Some are more complicated than others.

Professional scan tools enable mechanics to observe the car's network and run various self-tests. These are real time savers, however they're also expensive, and out of the budget of many DIYers.

If your OBD2 scan tool isn't turning on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's likely that a fuse has failed. This is the most frequent reason for a scan tool to fail. It is usually simple to fix the issue by replacing the fuse blowing up.
