fiat spare key Panda Key Fob Replacement

fiat 500 key programming fiat panda key replacement keyfobs are equipped with a transponder that sends an electronic signal from the fob to the car in order to unlock doors or start the motor. However, the fob could be inoperable due to various reasons.

A dead coin battery is the most common reason for malfunctioning keys. Other causes include water damages or a damaged module and interference signals.

Dead Coin Battery

Replace the battery if the key fob has died. Use a new button cell battery that is exactly the same size, voltage and specification as the previous one.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned before using again. The best method is how to get a new fiat 500 key use an old towel soaked in isopropyl, or electronic cleaner.

If the key fob hasn't been exposed to water, but remains inoperable it could be due to an issue with the receiver module or an internal electronic chip. In these situations it is possible to re-programme the key fob with an OBDII scanner can help.

Water Damage

You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to allow the fob to dry completely before installing a new battery.

If your key fob has stopped working, even after replacing the battery and programming it again, you might have a faulty receiver module. You can find the instructions for reprogramming most vehicles' remote keys on YouTube or consult the owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob can cause this, as can water exposure. If your key fob has stopped functioning due to water exposure it is possible fix the issue if you clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob does not respond to cleaning, it is possible that the module has issues and needs to be replaced. A damaged receiver module may also cause the remote control key to stop working. This is usually due to electromagnetic interference.

A malfunctioning electronic chip

The chip inside your key fob plays a crucial function in the anti-theft security system in your car key cover fiat 500. It transmits a signal to the immobiliser device in your car to determine whether the key is in fact valid. If the chip is damaged or broken, your vehicle will not start.

A malfunctioning chip can be caused by interference from objects, bad weather or transmitters in the vicinity of your vehicle. In this case, a new fob will be required.

Contacts with the battery may be damaged.

The battery contacts on the fob's battery can be damaged through heavy use. If they are damaged or bent, the key fob will not be able to send any signals to the receiver modules in the car.

Modern fobs are constructed 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 circuit.

The key fob contains an electronic chip that communicates with the vehicle's immobilizer in order to start it. This system uses crypto coding systems in the latest vehicles as well as the traditional red key system used in older models. If the chip is damaged it will have to be replaced.

A faulty 12 Volt battery

A malfunctioning battery could cause the key fob to work. When this occurs, the car's computer system won't recognize that the remote is within the vehicle.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly then it's time to replace the battery.

To test the battery's capacity put an electrical load on it for a couple of minutes. This will remove 1percent of the surface charges. After that, take the voltage again. The longer a battery can keep its voltage steady, the better its capacity. Ideal is to hold close to 12 volts during several minutes.

Problems with Radio Signal

This is the most typical reason for the key fob to stop sending signals to a car. The issue can be fixed by replacing the battery. It is however important to choose a battery that has the same size and voltage as the original.

Fobs aren't impervious to damage and can withstand a lot. Contacts on batteries and buttons can be damaged by rough handling.

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

Incorrect OBDII scan tool

There are a number of reasons why a scanner might not work. Some are more complicated 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 expensive and are out of reach for most DIYers.

If your OBD2 scan tool won't power on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's likely that a fuse has failed. This is the most common reason for failure of the scan tool. It is often simple to fix the issue by replacing the fuse that was blown.
