20 Resources That Will Make You Better At Fiat 500 Keys

Fiat Panda key fobs contain a transponder chip that sends a signal to your car to unlock the doors or start the engine. The fob might stop working due to a variety reasons.

A dead coin battery is the most frequent reason for key fob malfunctions. Other reasons include water damage, the receiver module is defective, and signal interference.

Dead Coin Battery

Replace the battery if your key fob is dead. Use a brand new button battery with exactly the same size, voltage, and specification as the original.

If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned prior to using it again. The best method is to use an old towel soaked in isopropyl, or electronic cleaner.

If the key fob isn't working even though it is not exposed to water it could be due a malfunction in the receiver module or in the internal electronic chip. In these instances it is possible to re-programme the key fob using an OBDII scanner may help.

Water Damage

There could be water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's generally possible to repair it by taking the batteries off and cleaning the circuit board with ruby alcohol. It is best to let the circuit board completely dry before installing batteries.

You could have a damaged module if your key fob stops working after replacing the battery or updating. You can find instructions for reprograming the majority of remote keys on YouTube or in your owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. If the chip is damaged, it cannot longer transmit and receive signals to the vehicle. Dropping the key fob can result in this, as can water exposure. If your key fob has stopped working due to water exposure it is possible to fix it if clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob doesn't respond to cleaning, it is possible that the receiver module has a fault and needs to be replaced. A faulty receiver module can also cause the remote control key to not function. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is an important element of the anti-theft device in your car. It sends out a signal the immobiliser unit of your car to inform it whether or not the key is valid. The car won't start when the chip is damaged.

A defective chip can be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency in close proximity to your car. In this instance an upgrade to the fob will be required.

Faulty Battery Contacts

The battery contacts on the fob's battery can be damaged through heavy use. If they're broken or bent, the fob won't send any signals to the receiver modules inside the car.

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

The key fob contains the chip that connects to the vehicle's immobilizer system in order to start it. This system utilizes cryptocoding systems in vehicles that are more modern, or the old red key system in older models. This chip needs to be changed if it is damaged.

Faulty 12 Volt Battery

A damaged battery can cause the remote to stop working. The car's system will not recognize the remote when this occurs.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically then it's time to replace it.

To test a battery's capacity to determine its capacity, put an electric load on it for a few minutes. This will take away 1% of the surface charges. Then, you can measure the voltage. The better the battery's capacity is, the longer it will keep its voltage. The ideal scenario is to keep it at or near 12 volts for several minutes.

Problems with Radio Signal

This is the most frequent reason for keys not sending signals to vehicles. The battery could be replaced to fix this issue. However, it is important to choose a battery that has the same size and voltage as the original.

Fobs take a lot of abuse, and they aren't impervious to destruction. Battery contacts and buttons can be damaged by rough handling.

Other transmitters or objects operating on the same frequency may also disrupt a signal. A light control panel in your home, for instance, may interfere with key fobs which use the same bandwidth. This could affect the remote control of your car.

Afflicted OBDII scan tool

There are many reasons scanners may not perform. Some are more complicated than others.

Professional scan tools allow a mechanic to observe the car's networks and run a range of self-tests. These are real time savers but they're also expensive, and beyond the budget of many DIYers.

If your OBD2 scanner won't turn on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition, it's likely that a fuse has blown. This is the main cause of scan tool failure. It is typically simple to fix the issue by replacing the blown fuse.
