fiat punto key fob Panda Key Fob Replacement

fiat 500 key replacement Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car that allows it to unlock doors or start the motor. The fob might stop working due to a variety reasons.

A dead battery for the coin is the most frequent reason for malfunctioning keys. Other causes include water damage, the receiver module is defective and signal interference.

Dead Coin Battery

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

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned prior to using it again. A paper towel soaked in alcohol or electronic cleaner can be the solution.

If the key fob hasn't been exposed to water, but still does not work, there may be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob through an OBDII scan could help in these instances.

Water Damage

If your key fob took immersed in a puddle or pool or gone down the washing machine, you might have some water damage. It's generally possible to get it back in working order by taking the batteries off and cleaning the circuit board with ruby alcohol. It is best to let the circuit board completely dry prior to installing batteries.

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

Faulty Receiver Module

The Key Fiat fob's chip is the chip that communicates the vehicle's system. If this chip becomes damaged, it will be unable to longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or by water exposure. If the key fob stops functioning after exposure to water, it may be possible to repair it by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the fiat key fob fob won't respond to cleaning, it's possible that the component has a fault and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to stop working. This is usually caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside your key fob is a vital component of the anti-theft systems in your vehicle. It sends out a signal the immobiliser unit in your car to inform it whether or not the key is in fact valid. The car will not start in the event that the chip has been damaged.

A damaged chip could be caused by interference signals from other objects like bad weather conditions or transmitters on the same frequency near your vehicle. In this situation it is likely that a new fob would be needed.

Contacts for the battery that are damaged

The battery contacts of the fob's battery can be damaged by excessive usage. If they are bent or broken the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs come with rubber seals in order to keep out water. Submerging them in water even if it is just a light drizzle or splash, can damage the chip's electronic components.

The key fob contains chips that communicate with the vehicle's immobilizer to allow it to allow it to start. The system uses the red keys of older vehicles or the cryptocoding system that is used in modern vehicles. This chip needs to be replaced if faulty.

Faulty 12 Volt Batterie

A damaged battery can cause the key fob to cease working. The fiat 500 car keys's computer won't recognize the remote if this happens.

Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly it's time to change it.

To test the battery's power, place an electrical load on it for a couple of minutes. This will eliminate 1percent of the surface charges. After that, measure the voltage. The longer a battery is able to hold its voltage, the better its capacity. Ideal is that it stays close to 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most common reason for the key fob not sending signals to cars. The battery can be replaced to fix this problem. But, it is essential to select a replacement battery with the same size and voltage as the original.

Fobs aren't indestructible and are susceptible to damage. Battery contacts and buttons can be damaged through rough handling.

A signal can also be interrupted by other transmitters or objects which use the same frequency. For instance, a light-control panel in your home could transmit interference using the same frequency as key fobs utilize. This can affect the remote control of your car.

Faulty OBDII scan tool

There are many reasons why a scan tool could not work. Some are more complex than others.

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

If your OBD2 scan tool doesn't turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present the chances are that a fuse is blowing. This is one of the most frequent reasons for failure of the scanner. The simple fix is usually to replace the blown fuse.
