fiat doblo key programming Panda keyfobs are equipped with a transponder that transmits signals from the fob to the car to unlock doors or turn on the motor. However, the key fob may stop working for several reasons.

308785165_499195788347328_5859105632268553197_nlow.jpgThe most commonly cited reason for key fob failure is the battery of the coin is dead. Other causes include water damages, a faulty module, and interference signals.

Dead Coin Battery

If your key fob's battery is dead, the first thing to do is replace it. Make use of a new button battery that has the same size, voltage and specifications as the original.

If the key fob has been exposed to water, for example a splash of rain or salt water on the beach, it will have to be cleaned before it can be used again. The trick is to use the paper towel and soak it in isopropyl or electronic cleaner.

If the key fob is not working despite not being exposed to water it could be due to a malfunction in the receiver module, or even in the internal electronic chip. In these instances, reprogramming the key fob using an OBDII scanner might help.

Water Damage

If your key fob has gotten an immersion in the pool or puddle, or taken a trip to the washing machine, you may have some water damage. It's generally possible to get it back in working order by getting rid of the batteries and cleaning the circuit board with ruby alcohol. It is a good idea to allow the fob to dry completely before putting in a brand new battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or replacing it with. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is an electronic chip that 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. Dropping the key fob can result in this, as can water exposure. If the key fob you have purchased has stopped functioning due to exposure to water and you are unable to fix it if you clean the chip with electronic cleaner or isopropylethanol.

If the key fob does not respond to cleaning, it is possible that the module has an issue and should be replaced. A faulty receiver can also cause the key to not work. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in the key fob is a vital component of the anti-theft systems in your vehicle. It sends a signal to the immobiliser unit in your vehicle to tell it whether the key is in fact valid. Your car won't start in the event that the chip is damaged.

A malfunctioning chip can be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this situation you'll need a new key fob.

Contacts for the battery that are damaged

The battery contacts of a key fob can be damaged due to heavy use. If they are broken or bent, the fob will not send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals in order to keep out water. A splash of water or a light rain should be fine however, submerging them in saltwater could damage the chip's electronic components.

The fiat a602 key fob has a chip which communicates with the immobilizer system of the vehicle in order to start it. The system utilizes the old red keys that were used in older vehicles or the cryptocoding system found in newer cars. This chip will have to be replaced if faulty.

The 12 Volt Battery is faulty

A damaged battery could cause the key fob not to work. When this occurs, the car's computer system won't recognize that the remote is within the vehicle.

Before replacing the battery, test it with the voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls dramatically it is 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 few minutes. This will take away about 1 percent of the surface charge. After that, take the voltage once more. The longer the battery can keep its voltage steady greater is its capacity. The ideal scenario is to keep it at 12 volts or less for several minutes.

Radio Signal Faulty Radio Signal

This is the most typical reason for keys not sending signals to the car. The battery can be replaced to fix this problem. It is important to buy batteries that have the same dimensions and voltage as the original.

Fobs can take a lot abuse, but they're also not indestructible. The battery buttons and contacts are delicate and can be bent or damaged by rough usage.

The signal could also be disrupted by other transmitters or objects that operate on the same frequency. A light-control panel at your home, for instance can interfere with key fobs that have the same frequency. This could affect the remote control of your car.

The tool is not working properly. OBDII scan tool

There are many reasons scanners may not function. Some are more complicated than others.

Professional scan tools enable mechanics to observe the car's networks and run various self-tests. These are real time savers, however they are also extremely expensive and are out of the budget of most DIYers.

If your OBD2 scan tool fails to turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, it's likely that a fuse has blown. This is among the most frequent causes of a scan tool failing. The easiest solution is to replace the fuse that has been blown.
