Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends a signal to your car to open the doors and start the engine. The fob can stop functioning due to a variety reasons.

A dead coin battery is the most common cause of a key fob malfunction. Other causes include water damages, a faulty module, and interference signals.

Dead Coin Battery

Replace the battery if the key fob has died. Use a brand new button battery that has identical in size, voltage and specifications as the old one.

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

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

Water Damage

If your key fob has gotten an immersion in the pool or puddle or even a trip through the washing machine, you could be suffering some water damage. It's generally possible to fix it by removing the batteries and cleaning the circuit board using ruby alcohol. It is best to let the circuit board completely dry before installing a battery.

There could be a problem with the module if your key fob stops working after replacing the battery or replacing it with. You can find reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob can cause this, as can water exposure. If your key fob has stopped functioning due to water exposure it is possible to fix it by attempting to clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob does not respond to cleaning, it is likely that the module is in issues and needs to be replaced. A faulty receiver module can also cause the remote control key to not function. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip in the key fob is a crucial element of the anti-theft device in your vehicle. It transmits a signal to the immobiliser device in the vehicle to determine whether the key is in fact valid. If the chip is damaged or damaged, your car won't start.

A malfunctioning chip can be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this scenario an upgrade to the fob will be required.

Faulty battery contacts

The battery contacts on a key fob are very fragile and are susceptible to damage by repeated use. If spare key fiat 500 are bent or broken the fob will not send any signals to the receiver modules in the car.

Modern fobs are made with rubber seals that keep out water. A splash of water or light rain should be fine however, submerging them in salt water could damage the electronic chip.

The key fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle to start it. The system is based on the old red keys in older vehicles as well as the cryptocoding system that is used in modern vehicles. If the chip is not working properly and needs to be replaced.

Faulty 12 Volt Battery

A damaged battery can cause the key fob to cease to function. The car's computer won't recognize the remote if this occurs.

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

Set an electrical load for a short time on the battery to test its capacity. This will take away approximately 1 percent of the charge on the surface. Then, you can measure the voltage. The greater the battery's capacity is, the longer it will keep its voltage. Ideally, it should remain at 12 volts or less for several minutes.

Radio Signal Faulty Radio Signal

This is the most frequent reason for keys not sending signals to vehicles. The issue can be fixed by replacing the battery. However, it is important to select a replacement battery that is the same voltage and size as the original one.

Fobs endure a lot of abuse, but they're also not impervious to destruction. The battery buttons and contacts are brittle and are susceptible to being bent or broken by excessive use.

A signal can also be impacted by other transmitters or objects who use the same frequency. For instance, a light-control panel near your home may transmit interference using the same frequency as key fobs utilize. This could interfere with the remote control in your car.

Faulty OBDII scan tool

There are many reasons why a scan tool may not work. Some are more complicated than others.

Professional scan tools let a mechanic observe the car's network and perform various self-tests. They can be huge time-savers, but they can also be very expensive, and beyond the reach of 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 both are in good condition the fuse could have ruptured. This is among the most frequent reasons for failure of the scanner. The simple fix is usually to replace the fuse that is blowing up.
