fiat key Panda key fobs contain transponder chips that send the signal to your vehicle to open the doors and start the engine. The fob can stop functioning due to a variety of reasons.

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

Dead Coin Battery

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

If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned prior to being used again. A paper towel soaked in alcohol or electronic cleaner can do the trick.

If the key fob has not been exposed to water, but remains inoperable, there may be a problem with the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner might assist.

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 back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to allow the device to completely dry before installing batteries.

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

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit or receive signals to the vehicle. The key fob being dropped can result in this, as can exposure to water. If your key fob stopped functioning due to water exposure it is possible fix the issue if you clean the chip with electronic cleaner or isopropyl alcohol.

However, if the key fob is still unable to not respond after cleaning it there is a good chance that the module is faulty and must be replaced. A malfunctioning receiver could cause the fiat punto key programming to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in the key fob is a vital component of the anti-theft systems in your car. It transmits a message the immobiliser inside your car to tell it whether the key is genuine. Your car will not start in the event that the chip is damaged.

A faulty chip may also be caused by interference from objects, bad weather or transmitters near your vehicle. In this scenario the replacement fob will be needed.

Contacts with the battery may be damaged.

The battery contacts inside the key fob are delicate and could be damaged with hard usage. If they're damaged or bent, the fob will not send any signals to the receiver modules in the car.

Modern fobs are designed with rubber seals to keep out water. Immersing them in water, even if it is just a light drizzle or splash could harm the chip's electronic circuit.

The key fob is equipped with chips that communicate with the vehicle's immobilizer system in order to start it. The system uses the red keys of older vehicles or the crypto coding system in newer cars. If this chip is faulty it must be replaced.

Problematic 12 Volt Battery

A malfunctioning battery could cause the fiat key fob replacement fob to cease to function. The car's system will not recognize the remote when this happens.

Before you replace the battery, you should test it with a a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly it is time to replace the battery.

Set an electrical load for a short period of time on the battery to determine its capacity. This will eliminate approximately 1% of the charge on the surface. Then, you can measure the voltage once more. The longer the battery can keep its voltage steady more effectively, the greater its capacity. Ideal is to hold at or near 12 volts for several minutes.

Problems with Radio Signal

This is the most frequent reason for the key fob not sending signals to cars. The battery can be replaced to solve this problem. It is important to buy a battery that has the same dimensions and voltage as the original.

Fobs take a lot of abuse, but they're also not impervious to destruction. The battery buttons and the contacts are fragile and are susceptible to being bent or damaged by rough use.

A signal can also be interrupted by other transmitters or objects who use the same frequency. For instance, a light control panel close to your home can send interference over the same bandwidth that key fobs use. This could affect the remote control of your car.

Incorrect OBDII Scan Tool

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

Professional scan tools enable a mechanic observe the car's network and perform various self-tests. These tools can save a lot of time, but are expensive and not accessible to most DIYers.

If your OBD2 scan tool isn't turning on, 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 is blowing. This is the most common reason for failures of the scanner. The simple fix is usually to replace the fuse which has blown.
