fiat ducato key fob programming Panda Key Fob Replacement

fiat key programmer Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car to unlock doors or turn on the motor. However, the fob can not function due to a variety of reasons.

The most commonly cited reason for key fob failure is a dead coin battery. Other causes are water damage, the receiver module is defective and signal interference.

Dead Coin Battery

If the battery in your key fob has died, the first step is to replace it. Choose a new button battery with the same size, voltage, and specification as the old one.

If the key fob has been exposed to water, like a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will work wonders.

If the key fob doesn't working despite not being exposed water it could be due to a problem in the receiver module or in the internal electronic chip. In these situations it is possible to re-programme the key fob with an OBDII scanner could assist.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to allow the device to completely dry prior to installing the battery.

If your key fob stopped working even after replacing the battery and programming it again, you might have a problem with the receiver module. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. If this chip becomes damaged, it can no longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or due to exposure to water. If the spare key for fiat 500 fob you have purchased has stopped functioning due to water exposure and you are unable fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.

If the fiat multipla key fob won't respond to cleaning, it is possible that the receiver module has issues and needs to be replaced. A defective receiver can cause the key to not work. This is usually caused by electromagnetic interference.

A defective electronic chip

The electronic chip that is in your key fob is a vital part in the anti-theft security system of your car. It transmits a signal to the immobiliser unit of your car to determine whether the key is in fact valid. If the chip is damaged or broken, the car won't start.

A defective chip can be caused by interference signals from other objects or weather conditions that are bad, or transmitters on the same frequency as your vehicle. In this situation you'll require a new key fob.

Faulty Battery Contacts

The battery contacts in a key fob are very fragile and are susceptible to damage through repeated use. If they're damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals in order to keep out water. Submerging them in water, even if it's just the slightest splash or drizzle could damage the chip's electronic circuit.

The key fob houses an electronic chip that communicates with the vehicle's immobilizer system to allow it to start. It uses the old red keys for older vehicles or the cryptocoding system used in the latest vehicles. The chip must be replaced if damaged.

A faulty 12 Volt battery

A faulty battery may cause the key fob not to function. The car's system will not recognize the remote if this occurs.

Before replacing the battery, test it using a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly it's time to change it.

Set an electrical load for a short time on the battery to determine its capacity. This will remove about 1 percent of the surface charge. After that, take the voltage once more. The better the battery's capacity and the longer it can maintain its voltage. It is ideal to maintain at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for the key fob not sending signals to vehicles. This problem can be solved by replacing the battery. However, it is important to buy a new battery that has the same voltage and size as the original.

Fobs can take a lot abuse, and they aren't indestructible. Battery contacts and buttons can be damaged by rough handling.

Other transmitters or objects that use the same frequency could also interfere with the signal. For instance, a light control panel in your home could transmit interference on the same bandwidth that key fobs use. This could cause interference with your car's remote control.

Faulty OBDII scan tool

There are many reasons why a scanner could not function. Some are more complex than others.

Professional scan tools let mechanics to observe the car's network and perform various self-tests. These are great time savers, but they are also extremely expensive, and beyond the range of most DIYers.

If your OBD2 scan tool won't power on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it could be that a fuse has been blown. This is the most frequent reason for a scan tool to fail. It is generally easy to fix the problem by replacing the blown fuse.
