fiat 500 locked keys in car Panda Key Fob Replacement

Fiat Key Cutting Panda keyfobs are equipped with a transponder which transmits a signal from the fob to the car in order to unlock doors or start the motor. The fob could stop working for a variety of reasons.

A dead battery for the coin is the most frequent reason for a key fob malfunction. Other causes include water damage, the receiver module is defective, and signal interference.

Dead Coin Battery

If your key fob's battery is dead, 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 has been exposed to water, like a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. The best way to do this is using an old towel soaked in isopropyl or an electronic cleaner.

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 internal electronic chip. Reprogramming the keyfob using an OBDII scan can aid in these situations.

Water Damage

If your key fob has gotten submerged in a pool or puddle or gone down the washing machine, it could 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's best to let the fob dry completely prior to installing a new battery.

If your key fob has stopped working even after replacing the battery and reprogramming it, you may have a faulty receiver module. You can find information on reprograming the majority of remote keys on YouTube or consult your owner's manual. 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 the chip is damaged, it can no longer send and receive signals to the vehicle. This could be due to dropping the key fob or by exposure to water. If the key fob is not functioning after exposure to water, it is possible to fix it by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob doesn't respond to cleaning, it's possible that the module has issues and needs to be replaced. A defective receiver can cause the key to cease to function. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip that is in your key fob plays a vital role in the anti-theft security system in your car. It sends a signal to the immobiliser in your car to inform it if the key is valid. Your car will not start in the event that the chip has been damaged.

A malfunctioning chip could be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency in close proximity to your car. In this instance you'll require a new key fob.

Contacts of the battery may be damaged.

The battery contacts on the key fob are delicate and can get damaged through repeated use. If they are damaged or bent, the key fob won't send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals to keep out water. Submerging them in water, even if just the slightest splash or drizzle can harm the chip's electronic components.

The key fob has a chip that communicates with the vehicle's immobilizer to allow it to begin it. The system utilizes the old red keys for older vehicles as well as the cryptocoding system used in modern vehicles. If the chip is not working properly, it will need to be replaced.

Faulty 12 Volt Battery

A damaged battery can cause the remote to stop working. The car's computer will not recognize the remote if this occurs.

Before you replace the battery, test it with an voltmeter to gauge its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly it's time to change it.

To test the battery's capacity to determine its capacity, put an electric load on it for a couple of minutes. This will take off approximately 1 percent of the charge on the surface. Then, you can measure the voltage. The better the battery's capacity and the longer it can maintain its voltage. Ideal is to hold close to 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason for a key fob to stop sending signals to the car. The battery can be replaced to solve this issue. It is essential to purchase an identical battery voltage and dimensions as the original.

Fobs endure a lot of punishment, and aren't impervious to destruction. The battery buttons and contacts are brittle and can be bent or broken by excessive use.

Other objects or transmitters using the same frequency can interfere with the signal. For instance, a light control panel near your home may send interference over the same frequency as key fobs utilize. This could affect the remote control of your car.

Afflicted OBDII scan tool

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

Professional scan tools allow a mechanic to look over the car's networks and run a variety of self-tests. These tools can save you a lot of time, but are costly and are out of reach for most DIYers.

If your OBD2 scan tool doesn't turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they are all OK there is a chance that a fuse has failed. This is the most common reason for failures of the scanner. It is often easy to fix the issue by replacing the fuse that was blown.
