fiat key duplication Panda Key Fob Replacement

Fiat 500X Key Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car to open doors or start the motor. The fob could stop working due to a variety reasons.

The most frequent cause of key fob malfunction is an inoperable coin battery. Other causes include water damage, a faulty module, and interference signals.

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Make use of a new button battery with exactly the same size, voltage, and specification as the previous 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. The best solution is to use an old towel soaked in isopropyl, or electronic cleaner.

If the key fob has not been exposed to water, but still does not work it could be a problem with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner may aid.

Water Damage

There could be water damage if your key fob was submerged in a puddle, pool or washing machine. You can usually get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely prior to installing a new battery.

It could be that you have a defective module when your key fob ceases working after replacing the battery or reprogramming. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip which communicates with the vehicle's system. If the chip is damaged, it will be unable to longer transmit or receive signals to the vehicle. This could be due to dropping the key fob, or by exposure to water. If the key fob has stopped working after exposure to water, it may be possible to fix it by cleaning the chip using isopropyl alcohol or electronic cleaner.

However, if the key fob does not respond even after cleaning it it is likely that the module is faulty and will require to be replaced. A defective receiver can cause the key to not work. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is a crucial part of the anti-theft system in your car. It sends out a signal the immobiliser device in your car to determine whether or not the key is valid. Your car will not start if the chip is damaged.

A damaged chip could be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this situation you'll require an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts on the key fob could be damaged due to heavy use. If they are bent, or broken, the fob won't transmit any signals to receiver modules inside the vehicle.

Modern fobs come with rubber seals that keep out water. A splash of water or a light rain should be fine but submerging them into salt water could cause damage to the chip's electronic components.

The key fob comes with chip that communicates with the immobilizer system of the vehicle, allowing it to start it. This system uses crypto coding systems in modern vehicles, or the old red key system used in older ones. If the chip is defective it will have to be replaced.

Problematic 12 Volt Battery

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

Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically, it's time to replace it.

To test the battery's power put an electrical load on it for a couple of minutes. This will remove about 1% of the surface charge. Then, you can measure the voltage. The better the battery's capacity, the longer it can maintain its voltage. Ideally, it will remain close to 12 volts several minutes.

Problems with Radio Signal

This is the main reason for a keyfob that ceases to send signals to the car. This problem can be solved by replacing the battery. It is however important to choose a battery with the same size and voltage as the original.

Fobs take a lot of abuse, and they aren't impervious to destruction. The battery contacts and buttons are delicate and are susceptible to being bent or broken by the force of.

Other transmitters or objects that use the same frequency can interfere with the signal. For example, a light-control panel near your home may send interference on the same frequency as key fobs use. This could interfere with the remote control of your car.

Faulty OBDII scan tool

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

Professional scan tools enable mechanics to observe the car's networks and conduct a variety self-tests. These tools can help save time, but they are costly and out of reach for the majority of DIYers.

If your OBD2 scanner doesn't work Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's likely that a fuse has been blown. This is the most common reason for failure of the scan tool. It is usually easy to fix the problem by replacing the fuse that was blown.
