A Brief History Of The Evolution Of Fiat 500 Keys

fiat multipla key Panda Key Fob Replacement

fiat 500x key fob programming Panda key fobs contain a transponder chip that sends the signal to your vehicle to open the doors and start the engine. However, the fob can be inoperable due to various reasons.

The most common reason for key fob failure is the battery of the coin is dead. Other causes include water damages, a faulty module, and interference signals.

Dead Coin Battery

Replace the battery if the key fob is dead. Make use of a button cell 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 should be cleaned before using again. A paper towel soaked with isopropyl alcohol or electronic cleaner can be the solution.

If the key fob hasn't been exposed to water but still does not work it could be due to an issue with the receiver module or an internal electronic chip. In these instances it is possible that reprogramming the key fob with an OBDII scanner can assist.

Water Damage

If your key fob's battery has taken submerged in a pool or puddle, or taken a trip through the washing machine, you could be suffering some water damage. It is usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea allow the fob to dry completely before putting in a brand new battery.

If your fiat key replacement fob stopped working, even after replacing the battery and reconfiguring it, you may have a malfunctioning receiver module. You can find instructions for the reprogramming of most remote keys on YouTube, or consult the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the car's system. This chip will stop sending and receiving signals to the car if damaged. The key fob being dropped can result in this, as can exposure to water. If the key fob has stopped working after exposure to water, it could be possible to fix the issue by cleaning the chip with isopropyl alcohol or electronic cleaner.

However, if the key fob does not respond after cleaning it, there is a good chance that the component is damaged and must be replaced. A defective receiver module could also cause the remote control key to not function. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob is a crucial component of the anti-theft system in your vehicle. It transmits a signal to the immobiliser unit inside the vehicle to determine whether or not the key is in fact valid. The car will not start when the chip is damaged.

A defective chip can be caused by interference signals from objects, bad weather conditions or transmitters on the same frequency near your car. In this case the replacement fob will be needed.

Faulty battery contacts

The battery contacts on the fob's key can be damaged by heavy usage. If they're bent or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs are designed with rubber seals to keep out water. A splash of water or a light rain is fine However, submerging them in saltwater may cause damage to the chip's electronic components.

The key fob comes with an electronic chip that communicates with the immobilizer system of the vehicle to start it. The system utilizes the red fiat 500 locked keys in car of older vehicles or the cryptocoding system that is used in the latest vehicles. The chip must be changed if it is faulty.

Poor 12 Volt Battery

A defective battery can cause the remote to stop working. When this happens the car's computer will not recognize that the remote is inside the vehicle.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls dramatically, it is time to replace the battery.

To test a battery's capacity, place an electrical load on it for a couple of minutes. This will remove approximately 1 percent of the surface charge. Then, measure the voltage once more. The longer the battery is able to hold its voltage greater is its capacity. Ideal is to hold close to 12 volts over several minutes.

Problems with Radio Signal

This is the most frequent cause of a key fob that stops sending signals to the car. This issue can be fixed by replacing the battery. It is however important to choose a battery with the same voltage and size as the original.

Fobs endure a lot of abuse, but they're also not indestructible. The battery contacts and buttons could be damaged by rough handling.

Other transmitters or objects operating on the same frequency may also disrupt a signal. For instance, a lighting control panel near your home may send interference on the same frequency that key fobs utilize. This could affect the remote control of your car.

The tool is not working properly. OBDII scan tool

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

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

If your OBD2 scan tool won't power on, test the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK it could be that a fuse has blown. This is the most typical reason for failure of the scan tool. It is usually easy to fix the problem by replacing the blown fuse.
