fiat 500 key replacement cost Panda Key Fob Replacement

fiat 500 key fob replacement Panda keyfobs are equipped with a transponder that transmits an electronic signal from the fob to the car in order to unlock doors or turn on the motor. However, the key fob may stop working due to a variety of causes.

The most common reason for key fob failure is the battery of the coin is dead. Other causes include water damage malfunctioning receiver modules and signal interference.

Dead Coin Battery

If the battery in your key fob is dead, the first step is to replace it. Make use of a button cell battery with the same voltage, size and specification as your old one.

If the key fob has been exposed to water, for example a splash of rain or salt water on the beach, it needs to be cleaned before it can be used again. The best solution is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob doesn't 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 cases you can reprogramme the key fob with an OBDII scanner can assist.

Water Damage

If your key fob's battery has taken submerged in a puddle or pool or even a trip to the washing machine, reprogram it could have some water damage. It's usually possible to get it working by taking the batteries off 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 stopped working even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find the instructions for the reprogramming of most remote keys on YouTube, or consult the owner's manual. You can also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with the chip that communicates the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. This can be caused by dropping the key fob, or by water exposure. If the key fob stops working after exposure to water it could be 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 component has an issue and must be replaced. A faulty receiver module can also cause the remote control key to stop working. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is a crucial component of the anti-theft systems in your vehicle. It sends out a signal the immobiliser unit inside your car to determine whether the key is legitimate. Your car won't start if the chip is damaged.

A faulty chip can also be caused by interference signals from other objects, bad weather conditions or transmitters operating on the same frequency as your vehicle. In this situation the replacement fob will be needed.

Contacts for the battery that are defective

The battery contacts of the key fob are fragile and are susceptible to damage with hard usage. If they're bent, or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs come with rubber seals that keep out water. Immersing them in water, even if just an occasional drizzle or splash could damage the electronic chip.

The key fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. This system uses crypto coding systems in newer vehicles and the older red key system for older models. This chip will need to be replaced if malfunctioning.

Poor 12 Volt Battery

A defective battery can cause the key fob to function. When this occurs, the car's computer system cannot recognize that the remote is in the vehicle.

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

To test the battery's power, place an electrical load on it for a couple of minutes. This will remove about 1% of the charge on the surface. Then take another measurement of the voltage. The higher the capacity of the battery is, the longer it will keep its voltage. Ideal is to hold close to 12 volts during several minutes.

Radio Signal Faulty Radio Signal

This is the most frequent reason for keys not sending signals to the car. The battery can be replaced to fix this problem. But, it is essential to choose a battery with the same voltage and size as the original one.

Fobs take a lot of abuse, and they aren't impervious to destruction. Contacts on batteries and buttons can be damaged through rough handling.

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

Afflicted OBDII scan tool

There are many reasons why a scan tool might not work. Some are more complex than others.

Professional scan tools enable mechanics to monitor the car's networks and run various self-tests. These can be real time savers, but they're also expensive and are out of the reach of most DIYers.

If your OBD2 scanner won't start make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK, a fuse may have ruptured. This is one of the most common reasons for failure of the scanner. The easiest solution is to replace the fuse which has blown.
