fiat punto car key Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car in order to unlock doors or turn on the motor. The fob may stop working for a variety of reasons.

A dead coin battery is the most common reason for a key fob malfunction. Other causes include water damage the receiver module is defective and signal interference.

Dead Coin Battery

If your key fob's battery is dead, the first step is to replace it. Use a button cell 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 on the beach, it needs to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can work wonders.

If the key fob isn't working despite being not exposed to water it could be due to a malfunction in the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these instances.

Water Damage

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

It could be that you have a defective module in the event that your remote stops working after replacing the battery or updating. You can find reprogramming procedures for the majority of vehicles' remote key fobs on YouTube or in the owner's guide. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the car's system. If this chip becomes damaged, it will no longer transmit or receive signals to the vehicle. Dropping the key fob can result in this, as can water exposure. If your key fob has stopped working due to water exposure and you are unable to fix it if you clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob doesn't respond to cleaning, it's likely that the module is in issues and needs to be replaced. A defective receiver can cause the key to cease to function. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob is a vital role in the anti-theft security system of your car. It transmits a signal to the immobiliser unit of your car to inform it whether the key is valid. Your car won't start in the event that the chip is damaged.

A faulty chip can also be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency in close proximity to your car. In this situation you'll need a new key fob.

Contacts with the battery may be damaged.

The battery contacts inside a key fob are very delicate and could be damaged through repeated use. If they're bent, or damaged, the fob will not send any signals to receiver modules in the vehicle.

Modern fobs are constructed with rubber seals to keep out water. Submerging them in water even if it's just an occasional drizzle or splash could damage the chip's electronic components.

The key fob is equipped with chip that communicates with the immobilizer system of the vehicle to start it. The system is based on the red keys of older vehicles, or the cryptocoding system found in newer cars. If this chip is faulty it will have to be replaced.

The 12 Volt Battery is faulty

A defective battery can cause the key fob not to work. When this occurs the car's computer won't recognize that the remote is within the vehicle.

Before replacing the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery will read 12.6 volts. If the reading decreases significantly then it's time to replace the battery.

To test the battery's power put an electrical load on it for a few minutes. This will remove approximately 1 percent of the surface charge. After that, take the voltage once more. The greater the battery's capacity and the longer it can keep its voltage. The ideal is to keep it close to 12 volts during several minutes.

The radio signal is not working properly. Radio Signal

This is the main reason for keys not sending signals to a car. This issue can be fixed by replacing the battery. It is however important to choose a battery that is the same size and voltage as the original.

Fobs can take a lot abuse, but they're not indestructible. The battery buttons and contacts are brittle, so they can get bent or damaged by excessive use.

The signal could also be interrupted by other transmitters or objects who use the same frequency. For instance, a light control panel in your home could transmit interference on the same frequency as key fobs utilize. This could cause interference with the remote control in your car.

Faulty OBDII scan tool

There are many reasons why scanners don't work. Certain are more complicated than others.

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

If your OBD2 scan tool isn't turning on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are both present, it's likely that a fuse has blown. This is one of the most common causes of scan tool failure. The most straightforward fix is to replace the fuse that is blowing up.
