Ten Things Your Competitors Teach You About Fiat 500 Keys Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends signals to your car to open the doors and start the engine. The fob could stop working due to a variety reasons.

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

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Use a button cell that has 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 prior to being used again. The best solution is to use a paper towel soaked with isopropyl, or electronic cleaner.

If the key fob hasn't been exposed to water, but isn't working it could be due to an issue with the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner might help.

Water Damage

If your key fob's battery has taken an immersion in the pool or puddle or even a trip down the wash machine, you could be suffering some water damage. It's usually possible to get it working again by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the circuit board completely dry prior to installing batteries.

It could be that you have a defective module in the event that your key fob stops working after replacing the battery or updating. There are instructions for reprogramming most vehicles' remote keys on YouTube or in your 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 which communicates with the vehicle's system. If this chip becomes damaged, it can no longer transmit and receive signals to the vehicle. This can be caused by dropping the key fob, or by exposure to water. If your key fob isn't functioning due to exposure to water it is possible to fix it if clean the chip using electronic cleaner or isopropyl ethanol.

If the key fob still does not respond even after cleaning it then it is likely that the receiver module is not functioning properly and needs to be replaced. A malfunctioning receiver could cause the key to not work. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip that is in your key fob plays a vital function in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car that tells it that the key is valid. If the chip is damaged or broken, your car won't start.

A malfunctioning chip can be caused by interference from other objects, weather conditions or transmitters close to your vehicle. In this scenario it is likely that a new fob would be needed.

Contacts to the battery are not working properly.

The battery contacts of the fob's battery can be damaged due to heavy use. If they are bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs come with rubber seals to keep out water. A splash of water or a light rain should be fine but submerging them into 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 allow it to start. The system utilizes the old red keys for older vehicles or the cryptocoding system found in the latest vehicles. If this chip is faulty it will have to be replaced.

Problematic 12 Volt Battery

A damaged battery could cause the key fob to work. When this happens, the car's computer system will not recognize that the remote is within the vehicle.

Before you replace the battery, test it with a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops dramatically the time is now to replace it.

Place an electrical load for a few moments on the battery to test its capacity. This will take away 1percent of the charges. Then take another measurement of the voltage. The longer the battery can hold its voltage greater is its capacity. Ideal is that it stays 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. This issue can be fixed by replacing the battery. It is crucial to purchase a battery that has the same dimensions and voltage as the original.

The buttons are not impervious to destruction and can take a lot. The battery contacts and buttons are delicate and can be bent or broken with excessive use.

The signal could also be interrupted by other objects or transmitters that operate on the same frequency. A light-control panel at your home, for instance, may interfere with key fobs which use the same bandwidth. This could interfere with the remote control of your car.

Problems with OBDII Scan Tool

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

Professional scan tools let mechanics to monitor the car's networks and run various self-tests. These tools can save a lot of time, but they're expensive and out of reach for the majority of DIYers.

If your OBD2 scanner isn't turning on, check the voltage on 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 most common reason for failure of the scan tool. fiat 500 key fob is usually to replace the fuse that is blowing up.
