Don't Make This Mistake With Your Fiat 500 Keys

spare fiat 500 key Panda Key Fob Replacement

fiat 500 duplicate Key Panda keyfobs are equipped with a transponder, which sends signals from the fob to the car that allows it to unlock doors or start the motor. The fob could stop working due to a variety reasons.

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

Dead Coin Battery

If your key fob's battery has failed, the initial step is to replace it. Choose a button battery 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 before using again. The best way to do this is using the paper towel and soak it in isopropyl or an electronic cleaner.

If the key fob hasn't been exposed to water but remains inoperable, there may be an issue with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner might help.

Water Damage

It is possible to get water damage if your key fob was submerged in a puddle, pool or washing machine. It's generally possible to fix it by taking out the batteries and cleaning the circuit board using rubbing alcohol. It's a good idea to allow the fob to dry completely before putting in a brand new battery.

You may have a faulty module in the event that your remote stops working after replacing the battery or updating. Reprogramming instructions are available for most vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip that connects to the vehicle's system. If this chip becomes damaged, it cannot longer transmit or receive signals to the vehicle. This can be caused by dropping the key fob or through exposure to water. If the key fob stops working after exposure to water it could be possible to fix it by cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob still does not respond following cleaning, it is likely that the module is faulty and will need to be replaced. A damaged receiver module may also cause the remote control key to stop working. This is often caused by electromagnetic interference.

Faulty electronic chip

The electronic chip inside your key fob is a vital function in the anti-theft security system of your vehicle. It transmits a message to the immobiliser inside your car to inform it if the key is valid. The fiat punto car key replacement will not start when the chip is damaged.

A damaged chip could be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this instance, you will need an entirely new key fob.

Contacts to the battery are not working properly.

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

Modern fobs are constructed with rubber seals to keep out water. A splash of water or a light rain is acceptable, but submerging them in saltwater can cause damage to the chip's electronic components.

The key fob has an embedded chip that communicates to the immobilizer system of the vehicle, allowing it to start it. It uses the old red keys in older vehicles as well as the cryptocoding system found in the latest vehicles. The chip must be replaced if it's defective.

A faulty 12 Volt battery

A malfunctioning battery could 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 you replace the battery, test it using a the voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly then it's time to replace the battery.

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 remove about 1 percent of the charge on the surface. Then take another measurement of the voltage. The longer the battery is able to keep its voltage steady greater is its capacity. The ideal scenario is to keep it close to 12 volts for several minutes.

Faulty Radio Signal

This is the most frequent reason for a key fob to stop sending signals to cars. This issue can be resolved by replacing the battery. It is however important to purchase a battery with the same size and voltage as the original.

Fobs endure a lot of punishment, and aren't indestructible. The battery buttons and the contacts are fragile, so they can get bent or damaged from rough usage.

A signal may also be interrupted by other transmitters or objects who use the same frequency. A light-control panel in your home, for example could interfere with key fobs that use the same bandwidth. This could affect the remote control of your car.

Afflicted OBDII scan tool

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

Professional scan tools allow mechanics to examine the car's systems and perform a variety of self-tests. These can be real time savers, however they can also be very expensive, out of the range of most DIYers.

If your OBD2 scanner won't turn on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it could be that a fuse has been blown. This is one of the most frequent causes of scan tool failure. The easiest fix is to replace the fuse which has blown.
