Fiat Panda Key Fob Replacement

fiat 500 key replacement Panda keyfobs are equipped with a transponder that transmits an electronic signal from the fob to the car that allows it to unlock doors or turn on the motor. However, the key fob may not function due to a variety of reasons.

A dead battery for the coin is the most common cause of the malfunction of a key fob. Other causes include water damages or a malfunctioning module and interference signals.

Dead Coin Battery

If your key fob battery has died, the first step is to replace it. Use a new button cell battery that has identical in size, voltage and specifications as the original.

If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can be the solution.

If the key fob is not working even though it is not exposed to water it could be due a malfunction in the receiver module, or even in the internal electronic chip. In these situations you can reprogramme the key fob with an OBDII scanner can assist.

Water Damage

You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It is usually possible to get it working by removing the batteries and cleaning the circuit board using rubbing alcohol. It is recommended to let the fob completely dry before putting in a battery.

If your key fob has stopped working, even after replacing the battery and changing the program, you could have a faulty receiver module. There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer of your vehicle using the OBDII scanner 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 no longer be able to send or receive signals to the vehicle. This can be caused by dropping the key fob, or through exposure to water. If the key fob stopped functioning after exposure to water, it is possible to fix it by cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob still does not respond after cleaning it, there is a good chance that the receiver module is not functioning properly and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to stop working. This is usually due to electromagnetic interference.

Electronic chip that is malfunctioning

The chip inside your key fob plays a crucial part in the anti-theft security system of your car. It sends a message to the immobiliser inside your car to tell it whether the key is genuine. If the chip is damaged or damaged, your car will not start.

A faulty chip can also be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency close to your car. In this case you'll require a new key fob.

Contacts to the battery are not working properly.

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

Modern fobs are constructed with rubber seals to keep out water. A splash of water or a light rain should be fine but submerging them into saltwater may harm the electronic chip.

The key fob houses chips that communicate with the vehicle's immobilizer system to begin it. It uses the red keys of older vehicles, or the crypto coding system in newer cars. If the chip is damaged, it will need to be replaced.

Faulty 12 Volt Batterie

A faulty battery can cause the remote to cease to function. When this happens, the car's computer system cannot recognize that the remote is in the vehicle.

Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops 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 few minutes. This will remove approximately 1 percent of the charge on the surface. Then, measure the voltage again. The greater the battery's capacity and the longer it can maintain its voltage. It is ideal to maintain at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most typical reason for a key fob to stop sending signals to vehicles. This problem can be solved by replacing the battery. It is important to buy a battery that has the same dimensions and voltage as the original.

Fobs take a lot of abuse, but they're also not impervious to destruction. The battery buttons and contacts are delicate and are susceptible to being bent or broken with excessive use.

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

Faulty OBDII Scan Tool

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

Professional scan tools let mechanics to look over the car's network and run various self-tests. These are real time savers, but they can be expensive, and beyond the range of most DIYers.

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present, it's likely that a fuse has failed. This is among the most frequent causes of failures in the scan tool. The easiest solution is to replace the fuse that is blowing up.
