fiat 500 replacement key Panda Key Fob Replacement

Fiat Keys (Dnpaint.Co.Kr) Panda key fobs contain transponder chips that send a signal to your car to unlock the doors or start the engine. However, the fob can stop working for several reasons.

The most common cause of key fob failure is an inoperable coin battery. Other causes include water damage or a malfunctioning module and interference signals.

Dead Coin Battery

If your key fob battery has gone out of service, the first step is to replace it. Use a button cell with the same voltage, size and specifications as your previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to using it again. A paper towel soaked with isopropyl alcohol or electronic cleaner can be the solution.

If the key fob has not been exposed to water but isn't working it could be because of a problem with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner could help.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to get it working again by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob dry completely before putting in a brand new battery.

You could have a damaged module when your key fob ceases working after replacing the battery or reprogramming. There are reprogramming guidelines for most vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if damaged. Dropping the key fob can cause this, as can water exposure. If the key fob stopped working after water exposure it is possible to repair it by cleaning the chip using isopropyl alcohol or electronic cleaner.

However, if the key fob is still unable to not respond after cleaning it it is likely that the component is damaged and needs to be replaced. A defective receiver can cause the key to stop working. This is usually due to electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob plays an important part in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car that tells it that the key is valid. If the chip is damaged or broken, your car will not start.

A faulty chip can also be caused by interference signals from other objects like bad weather conditions or transmitters operating on the same frequency in close proximity to your car. In this case, a new fob will be needed.

Contacts with the battery may be damaged.

The battery contacts on a key fob are very delicate and could be damaged when used for long periods of time. If they are damaged or bent, the key fob will not send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals that keep out water. Submerging them in water even if it is just small splash or drizzle, can damage the chip's electronic components.

The key fob houses a chip that communicates with the vehicle's immobilizer system in order to activate it. It uses the old red keys that were used in older vehicles, or the crypto coding system in modern vehicles. The chip must be replaced if malfunctioning.

A faulty 12 Volt battery

A faulty battery can cause the key fob to cease working. When this happens the car's computer cannot recognize that the remote is in the vehicle.

Before you replace the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly, it is time to replace the battery.

To test the battery's power, place an electrical load on it for a few minutes. This will eliminate 1percent of the surface charges. Then, measure the voltage once more. The longer a battery can keep its voltage steady more effectively, the greater its capacity. The ideal is to keep it close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most common cause of a key fob that ceases to send signals to the car. This issue can be resolved by replacing the battery. It is essential to purchase batteries that have the same dimensions and voltage as the original.

Fobs can take a lot abuse, but they're also not impervious to destruction. Battery contacts and buttons can be damaged by rough handling.

The signal could also be interrupted by other transmitters or objects that use the same frequency. A light-control panel in your home, for instance can interfere with key fobs that use the same frequency. This can interfere with the remote control of your car.

Afflicted OBDII scan tool

There are many reasons why a scan tool could not work. Some are more complicated than others.

Professional scan tools let mechanics to observe the car's network and run various self-tests. These tools can save you a lot of time, but are expensive and not accessible to the majority of DIYers.

If your OBD2 scanner won't start examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present the chances are that a fuse has failed. This is among the most frequent causes of a scan tool failing. It is usually easy to fix the issue by replacing the fuse that has blown.
