fiat 124 spider key fob not working Panda Key Fob Replacement

Fiat 500 spare Key cost Panda keyfobs are equipped with a transponder that sends signals from the fob to the car to open doors or start the motor. However, the fob can stop working for several reasons.

A dead coin battery is the most common cause of key fob malfunctions. Other reasons include water damage, the receiver module is defective and Fiat 500 spare key Cost signal interference.

Dead Coin Battery

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

If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it will need to be cleaned before it can be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will work wonders.

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

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's usually possible to repair it by taking out the batteries and cleaning the circuit board using rubbing alcohol. It's best to allow the device to completely dry before installing a battery.

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

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This could be due to dropping the key fob, or through exposure to water. If the key fob stopped working after water exposure it may be possible to repair it by cleaning the chip using isopropyl ethanol or electronic cleaner.

However, if the key fob continues to not respond after cleaning it, you can be sure that the component is damaged and must be replaced. A defective receiver module could also cause the remote control key to not function. This is usually caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside your key fob plays an important role in the anti-theft security system of your vehicle. It sends out a signal the immobiliser unit in the vehicle to determine whether the key is in fact valid. Your car will not start if the chip is damaged.

A faulty chip may also be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this situation the replacement fob will be needed.

Contacts for the battery that are damaged

The battery contacts on a key fob can be damaged by excessive usage. If they're bent, or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.

Modern fobs have rubber seals that block out water. A splash of water or light rain should be fine, but submerging them in saltwater may cause damage to the chip's electronic components.

The key fob comes with a chip which communicates with the immobilizer system of the vehicle in order to start it. This system utilizes cryptocoding systems in the latest vehicles as well as the traditional red key system in older models. If the chip is not working properly it must be replaced.

Faulty 12 Volt Batterie

A damaged battery could cause the key fob to work. The car's computer will not recognize the remote if this occurs.

Test the battery using the help of a 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 it.

To test the battery's capacity put 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 the battery is able to keep its voltage steady more effectively, the greater its capacity. It should be close to 12 volts for several minutes.

Problems with Radio Signal

This is the most typical cause of a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. It is essential to purchase a battery that has the same voltage and dimensions as the original.

Fobs take a lot of punishment, and aren't impervious to destruction. The battery contacts and buttons could be damaged by rough handling.

A signal may also be affected by other transmitters or objects which use the same frequency. A light control panel in your home, for instance can interfere with key fobs which use the same frequency. This can interfere with the remote control in your car.

Incorrect OBDII scan tool

There are a variety of reasons why scanners don't function. Certain are more complicated than others.

Professional scan tools let mechanics to look over the car's network and perform various self-tests. These tools can save you a lot of time, but they're expensive and out of reach for the majority of DIYers.

If your OBD2 scan tool doesn't turn on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's possible that a fuse has failed. This is the main reason for failures of the scanner. The easiest fix is to replace the blown fuse.
