fiat key Fob replacement Panda Key Fob Replacement

fiat 500 replacement key cost Panda keyfobs are equipped with a transponder, which sends a signal from the fob to the car that allows it to unlock doors or turn on the motor. The fob may stop working due to a variety reasons.

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

Dead Coin Battery

Replace the battery in case your key fob is dead. Choose a button battery with the same voltage, size, and specifications as the old one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned before being used again. The trick is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob hasn't been exposed to water but it is still not working it could be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan may help in these instances.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. It is usually possible to restore it's functionality by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is recommended to let the board completely dry before putting in a battery.

If your key fob stopped working even after replacing the battery and reconfiguring it, you may have a defective receiver module. There are instructions for changing the programming of most remote keys on YouTube, or consult the owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. Dropping the key fob can cause this, as could water exposure. If the key fob is not functioning after exposure to water, it may be possible to repair it by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob still does not respond after cleaning it, there is a good chance that the module is defective and needs to be replaced. A defective receiver module could also cause the remote control key to cease functioning. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip that is in your key fob is a vital function in the anti-theft security system of your vehicle. It sends a message to the immobiliser inside your car to determine whether the key is genuine. If the chip is damaged or damaged, your car will not start.

A damaged chip could be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this scenario, a new fob will be required.

Contacts to the battery are not working properly.

The battery contacts of a key fob can be damaged due to heavy use. If they're bent or broken the fob won't send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals that block out water. A splash of water or a light rain should be fine, but submerging them in saltwater may damage the chip's electronic components.

The key fob comes with an embedded chip that communicates to the immobilizer system of the vehicle to begin it. The system utilizes the old red keys for older vehicles as well as the cryptocoding system found in the latest vehicles. The chip must be replaced if it's faulty.

A faulty 12 Volt battery

A malfunctioning 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 significantly then it's time to replace the battery.

Place an electrical load for a short period of time on the battery to test its capacity. This will eliminate about 1% of the surface charge. Then take another measurement of the voltage. The longer the battery is able to hold its voltage more effectively, the greater its capacity. Ideal is to hold close to 12 volts over several minutes.

Faulty Radio Signal

This is the main reason for keys not sending signals to cars. This problem can be solved by replacing the battery. It is however important to purchase a battery that has the same size and voltage as the original.

Fobs are subject to a lot of punishment, and aren't impervious to destruction. The battery contacts and buttons are delicate and are susceptible to being bent or broken by rough usage.

A signal can also be affected by other objects or transmitters that operate on the same frequency. A light-control panel at your home, for example could interfere with key fobs that use the same frequency. This can affect the remote control of your car.

Incorrect OBDII scan tool

There are a number of reasons why a scanner could not work. Certain are more complicated than others.

Professional scan tools allow a mechanic to monitor the car's network and run a variety of self-tests. These are real time savers but they are also extremely expensive, out of the budget of many DIYers.

If your OBD2 scan tool isn't turning on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it's likely that a fuse has blown. This is the most typical reason for a scan tool to fail. It is typically easy to fix the issue by replacing the fuse that was blown.
