Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain an transponder chip that transmits the signal to your vehicle to open the doors and start the engine. The fob might stop working due to a variety reasons.

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

Dead Coin Battery

If your key fob battery has gone out of service, the first step is to replace it. Use a new button cell battery with the same size, voltage, and specification as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned before using again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can work wonders.

If the key fob doesn't working despite not being exposed water, it could be due a malfunction in the receiver module or in the internal electronic chip. In these instances you can reprogramme the key fob with an OBDII scanner could aid.

Water Damage

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

If your key fob has stopped working even after replacing the battery and reconfiguring it, you may have a malfunctioning receiver module. There are instructions for changing the programming of most remote keys on YouTube, or consult the owner's manual. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob has an electronic chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car when it is damaged. The key fob being dropped can cause this, as could exposure to water. If the key fob you have purchased has stopped functioning due to water exposure, you may be able fix the issue if you clean the chip using electronic cleaner or isopropyl ethanol.

If the key fob doesn't respond to cleaning, it's possible that the component has an issue and must be replaced. A defective receiver module could also cause the remote control key to stop working. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob plays an important role in the anti-theft security system of your vehicle. It sends a message to the immobiliser in your car to inform it whether the key is legitimate. If the chip is damaged or broken, the car will not start.

A damaged chip could be caused by interference from objects, bad weather or transmitters close to your vehicle. In this case you'll require an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts of the key fob are delicate and can get damaged through repeated use. If they're bent or damaged, the fob will not transmit any signals to receiver modules in the vehicle.

Modern fobs are constructed with rubber seals in order to keep out water. In ignition switch of submerging them in water, even if it's just an occasional drizzle or splash could harm the chip's electronic components.

The key fob has an electronic chip that communicates with the vehicle's immobilizer in order to allow it to start. This system makes use of cryptocoding systems in modern vehicles and the older red key system for older ones. If this chip is faulty it will have to be replaced.

Faulty 12 Volt Batterie

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

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly the time is now to replace it.

To test the battery's capacity put an electrical load on it for a few minutes. This will remove approximately 1 percent of the charge on the surface. Then, measure the voltage once more. The longer the battery can keep its voltage steady more effectively, the greater its capacity. It is ideal to maintain at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason for keys not sending signals to cars. The battery could be replaced to fix this issue. However, it is important to select a replacement battery that has the same voltage and size as the original.

Fobs are subject to a lot of punishment, and aren't impervious to destruction. The battery contacts and buttons are delicate which means they could be bent or broken with rough usage.

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

Incorrect OBDII scan tool

There are many reasons scanners may not function. Some are more complicated than others.

Professional scan tools permit mechanics to monitor the car's network and perform a variety of self-tests. These tools can save time, but are costly and out of reach for the majority of DIYers.

If your OBD2 scan tool won't power on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's possible that a fuse is blowing. This is the most frequent cause of scan tool failure. The easiest solution is to replace the fuse which has blown.
