fiat 500 key Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors or start the engine. The fob might stop working for a variety.

The most frequent cause of key fob malfunction is an inoperable coin battery. Other causes include water damage or a malfunctioning module and interference signals.

Dead Coin Battery

If your key fob's battery has failed, the initial step is to replace it. Use a button cell battery with the same voltage, size and specification as your old one.

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

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

Water Damage

If your key fob's battery has taken a bath in the puddle or pool or gone to the washing machine, you could be suffering some water damage. It's usually possible to get it back in working order by taking out the batteries and cleaning the circuit board using rubbing 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 reconfiguring it, you may have a faulty receiver module. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset your computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. If the chip is damaged, it can no longer transmit and receive signals to the vehicle. 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 repair it by cleaning the chip with isopropyl alcohol, or electronic cleaner.

However, if the key fob is still unable to not respond even after cleaning it it is likely that the receiver module is not functioning properly and will need to be replaced. A faulty receiver can also cause the key to stop working. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in the key fob is an important element of the anti-theft device in your vehicle. It sends out a signal the immobiliser device in your vehicle to tell it whether or not the key is valid. Your car won't start in the event that the chip has been damaged.

A defective chip can be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency as your vehicle. In this case it is likely that a new fob would be required.

Contacts of the battery may be damaged.

The battery contacts on the key fob could be damaged due to heavy use. If they're bent or damaged, the fob will not send any signals to receiver modules inside the vehicle.

Modern fobs come with rubber seals to keep out water. A splash of water or light rain is acceptable however, submerging them in salt water could damage the chip's electronic components.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle to start it. The system relies on cryptocoding systems in newer vehicles, or the old red key system for older models. If this chip is faulty it must be replaced.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob to function. The car's system will not recognize the remote if this occurs.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly the time is now to replace it.

Place an electrical load for a short period of time on the battery to determine its capacity. This will take away 1% of the surface charges. Then measure the voltage again. The longer a battery can hold its voltage more effectively, the greater its capacity. Ideally, it will remain at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most common reason for a key fob that stops sending signals to the car. This issue can be resolved by replacing the battery. However, it is crucial to buy a new battery with the same size and voltage as the original one.

Fobs aren't indestructible and can withstand a lot. The battery buttons and contacts are delicate, so they can get bent or damaged by rough usage.

Other transmitters or objects that use the same frequency can also disrupt the signal. A light-control system in your home, for example, may interfere with key fobs using the same frequency. This could cause interference with your car's remote control.

Afflicted OBDII Scan Tool

There are many reasons scanner tools may not function. Certain are more complicated than others.

Professional scan tools let a mechanic observe the car's network, and run various self-tests. These tools can save a lot of time, but are costly and not accessible to most DIYers.

If your OBD2 scanner doesn't work examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're all fine the fuse could have blown. This is the most typical reason for a scan tool to fail. It is often easy to fix the issue by replacing the fuse that has blown.
