fiat 500 duplicate key Panda Key Fob Replacement

fiat 500 key cover uk fiat 500 key cutting car key cover [have a peek here] Panda key fobs contain a transponder chip that sends a signal to your spare car key fiat 500 to open the doors or start the engine. The fob can stop functioning due to a variety reasons.

A dead battery for the coin is the most common cause of key fob malfunctions. Other reasons include water damage, the receiver module is defective and signal interference.

Dead Coin Battery

Replace the battery if the key fob has died. Use a button cell that has the same voltage, size, 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 prior to using it again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will work wonders.

If the key fob doesn't working despite not being exposed to water it could be due to a glitch in the receiver module, or even in the internal electronic chip. In these cases, reprogramming the key fob using an OBDII scanner might assist.

Water Damage

You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It is usually possible to fix it by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It's a good idea to allow the fob to dry completely before putting in a new battery.

If your key fob has stopped working even after replacing the battery and programming it again, you might have a malfunctioning receiver module. There are instructions for reprograming the majority of remote keys on YouTube or refer to the owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has the chip that communicates the vehicle's system. If the chip is damaged, it cannot longer transmit and receive signals to the vehicle. This can be caused by dropping the key fob or by water exposure. If your key fob has stopped functioning due to water exposure it is possible to fix it if clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob continues to not respond even after cleaning it it is likely that the module is defective and will need to be replaced. A defective receiver can cause the key to not work. This is usually caused by electromagnetic interference.

Electronic chip that is malfunctioning

The chip that is embedded in the key fob is an essential part of the anti-theft system in your vehicle. It transmits a signal to the immobiliser unit of the vehicle to determine whether the key is legitimate. Your car will not start when the chip is damaged.

A malfunctioning chip could be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency close to your vehicle. In this situation you'll need an entirely new key fob.

Contacts for the battery that are defective

The battery contacts of the fob's battery can be damaged due to heavy use. If they're bent or damaged, the fob will not transmit any signals to receiver modules in the vehicle.

Modern fobs come with rubber seals that keep out water. A splash of water or light rain is acceptable but submerging them into saltwater may cause damage to the electronic chip.

The key fob has chips that communicate with the vehicle's immobilizer system to start it. It uses the old red keys for older vehicles or the cryptocoding system that is used in modern vehicles. If this chip is faulty it must be replaced.

Poor 12 Volt Battery

A malfunctioning battery could cause the key fob to cease to function. If this happens, the car's computer system will not recognize that the remote is within the vehicle.

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 drops dramatically then it's time to replace it.

To determine the capacity of a battery test the battery's capacity by placing an electrical load on it for a couple of minutes. This will eliminate approximately 1% of the surface charge. Then take another measurement of the voltage. The better the battery's capacity is, the longer it will keep its voltage. Ideal is that it stays at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

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

Fobs aren't impervious to damage and can take a lot. The battery buttons and the contacts are fragile and are susceptible to being bent or broken by excessive use.

A signal may also be interrupted by other objects or transmitters that operate on the same frequency. For instance, a light control panel that is near your home could send interference on the same frequency as key fobs use. This could affect the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons why scanners don't 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 time, but are costly and are out of reach for most DIYers.

If your OBD2 scanner won't start examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK, it's likely that a fuse is blowing. This is one of the most common causes of failures in the scan tool. The simple fix is usually to replace the blown fuse.
