fiat 500 replacement key 500 key fob (related web-site) Panda key fobs contain transponder chips that send the signal to your vehicle to open the doors and start the engine. However, the key fob may stop working due to a variety of causes.

The most common cause of key fob malfunction is the battery of the coin is dead. Other causes are water damage, a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has failed. Choose a new button battery with the same voltage, size and specifications like the previous one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can do the trick.

If the key fob has not been exposed to water, but remains inoperable it could be because of a problem with the receiver module or an internal electronic chip. In these situations it is possible to re-programme the key fob using an OBDII scanner can help.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. It is usually possible to get it back to working by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to allow the fob to dry completely before installing a new battery.

There could be a problem with the module in the event that your remote stops working after replacing the battery or changing the programming. You can find information on reprogramming most vehicles' remote keys on YouTube or consult the owner's manual. You could also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates the vehicle's system. If the chip is damaged, it can no longer transmit or receive signals to the vehicle. This can be caused by dropping the key fob, or through exposure to water. If your key fob isn't functioning due to water exposure or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropylethanol.

If the key fob does not respond even after cleaning it there is a good chance that the receiver module is not functioning properly and must be replaced. A damaged receiver can cause the key to cease to function. This is usually due to electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside your key fob plays an important role in the anti-theft system in your car. It sends a signal to the immobiliser inside your car to inform it that the key is valid. If the chip is damaged or broken, your car won't start.

A damaged chip could be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this case you'll require a new key fob.

Faulty battery contacts

The battery contacts on a key fob can be damaged through heavy use. If they are bent, or broken, the fob won't send any signals to receiver modules in the vehicle.

Modern fobs are constructed with rubber seals to keep out water. A splash of water or light rain should be fine but submerging them into saltwater can harm the electronic chip.

The key fob comes with a chip which communicates with the immobilizer system of the vehicle to begin it. It uses the red keys of older vehicles or the cryptocoding system used in newer cars. If this chip is faulty it must be replaced.

A faulty 12 Volt battery

A faulty battery can cause the key fob to stop working. The car's computer will not recognize the remote when this occurs.

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

To test a battery's capacity, place an electrical load on it for a few minutes. This will eliminate about 1 percent of the charge on the surface. Then measure the voltage again. The better the battery's capacity is, the longer it will keep its voltage. Ideally, it will remain close to 12 volts for several minutes.

Faulty Radio Signal

This is the most typical cause of a key fob that ceases to send signals to the car. The battery can be replaced to fix this issue. It is however important to purchase a battery with the same size and voltage as the original one.

Fobs can take a lot abuse, but they're also not indestructible. Contacts and buttons on batteries can be damaged through rough handling.

A signal may also be disrupted by other objects or transmitters that use the same frequency. For instance, a lighting control panel that is near your home could send interference over the same frequency as key fobs use. This can interfere with the remote control of your car.

Faulty OBDII Scan Tool

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

Professional scan tools let mechanics to monitor the car's networks and run various self-tests. These tools can save time, but they are costly and not accessible to the majority of DIYers.

If your OBD2 scan tool won't power on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are OK the chances are that a fuse has been blown. This is one of the most frequent causes of a scan tool failing. The simple fix is usually to replace the fuse that has been blown.
