Fiat Panda Key Fob Replacement

fiat ducato replacement key Panda keyfobs are equipped with a transponder, which sends signals from the fob to the car in order to unlock doors or start the motor. The fob can stop functioning due to a variety of reasons.

A dead coin battery is the most frequent reason for a key fob malfunction. Other causes include water damages as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery if your key fob has gone out of service. Use a new button cell battery with exactly the same size, voltage, and specification as the original.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned prior to being used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will help.

If the key fob doesn't working despite not being exposed to water it could be due to a malfunction in the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan may help in these cases.

Water Damage

If your key fob took immersed in a pool or puddle or even a trip to the washing machine, it could have some water damage. It's usually possible to restore it's functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the board completely dry before installing a battery.

If your key fob has stopped working, even after replacing the battery and changing the program, you could have a malfunctioning receiver module. Reprogramming instructions are available for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob could cause this, as could exposure to water. If the key fob you have purchased has stopped working due to water exposure or water exposure, you might be able to fix it if you clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob still does not respond even after cleaning it then it is likely that the module is defective and needs to be replaced. A malfunctioning receiver could cause the key to stop working. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob is a vital function in the anti-theft security system of your vehicle. It sends a signal the immobiliser device in your car to determine whether or not the key is legitimate. If the chip is damaged or broken, the car won't start.

A damaged chip could be caused by interference from objects, bad weather or transmitters near your vehicle. In this situation an upgrade to the fob will be required.

Contacts for the battery that are defective

The battery contacts of the key fob are delicate and can get damaged through repeated use. If they're bent or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs are equipped with rubber seals that keep out water. Submerging them in water even if just the slightest splash or drizzle could harm the electronic chip.

The key fob has an electronic chip that communicates with the immobilizer system of the vehicle, allowing it to start it. This system uses crypto coding systems in vehicles that are more modern and the older red key system in older models. If this chip is faulty, it will need to be replaced.

Faulty 12 Volt Batterie

A defective battery can cause the remote to cease working. When this happens the car's computer will not be able to recognize that the remote is inside the vehicle.

Before you replace the battery, you should test it with a the voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly the time is now to replace it.

Set an electrical load for a short period of time on the battery to gauge its capacity. This will remove approximately 1% of the surface charge. Then, you can measure the voltage once more. The better the battery's capacity and the longer it can keep its voltage. Ideal is that it stays at or near 12 volts for several minutes.

Problems with Radio Signal

This is the most common reason for a keyfob that stops sending signals to the car. This problem can be solved by replacing the battery. It is important to buy an identical battery dimensions and voltage as the original.

Fobs take a lot of punishment, and aren't indestructible. Contacts and buttons on batteries can be damaged by rough handling.

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

Incorrect OBDII Scan Tool

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

Professional scan tools allow a mechanic to examine the car's systems and run a variety of self-tests. These are great time savers but they're also expensive, and out of the budget of most DIYers.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's likely that a fuse has failed. This is among the most frequent causes of scan tool failure. It is typically simple to fix the issue by replacing the fuse that was blown.
