fiat car keys Panda Key Fob fiat replacement car keys

Fiat Panda key fobs contain a transponder chip which sends signals to your car to open the doors and start the engine. However, the fiat spare key fob may stop working for several reasons.

The most frequent cause of key fob malfunction is the battery of the coin is dead. Other causes include water damage or a damaged module and interference signals.

Dead Coin Battery

Replace the battery if your key fob has failed. Make use of a new button battery that is exactly the same size, voltage and specification like the previous one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it's going to need to be cleaned before it can be used again. A paper towel soaked in alcohol or electronic cleaner will be the solution.

If the key fob hasn't been exposed to water but still does not work it could be due to a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan could help in these instances.

Water Damage

If your key fob has taken an immersion in the pool or puddle, or taken a trip through the washing machine, you may have some water damage. It's usually possible to restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob completely dry prior to installing the battery.

If your key fob stopped working even after replacing the battery and reconfiguring it, you may have a defective receiver module. You can find reprogramming procedures for most vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. If this chip becomes damaged, it can no longer be able to send or receive signals to the vehicle. Dropping the key fob could cause this, as can exposure to water. If your key fob stopped working due to exposure to water it is possible to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

However, if the key fob does not respond after cleaning it it is likely that the module is faulty and needs to be replaced. A damaged receiver can cause the key to cease to function. This is usually due to electromagnetic interference.

A malfunctioning electronic chip

The chip that is embedded in your key fob is a vital component of the anti-theft systems in your car. It sends a signal to the immobiliser in your car to tell it whether the key is genuine. The car will not start if the chip is damaged.

A defective chip can be caused by interference signals from objects such as weather conditions, objects or transmitters operating on the same frequency as your car. In this situation you'll require an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts on the key fob are delicate and can get damaged when used for long periods of time. If they're bent, or broken, the fob won't send any signals to receiver modules in the vehicle.

Modern fobs are constructed with rubber seals that keep out water. Submerging them in water even if just small splash or drizzle could harm the electronic chip.

The key fob contains an embedded chip that communicates to the immobilizer system of the vehicle to begin it. The system is based on the old red locked keys in car boot fiat punto for older vehicles, or the cryptocoding system found in the latest vehicles. If the chip is defective, it will need to be replaced.

The 12 Volt Battery is faulty

A damaged battery can cause the key fob to stop working. When this occurs the car's computer will not be able to recognize that the fiat ducato remote key replacement is within the vehicle.

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

Place an electrical load for a short period of time on the battery to test its capacity. This will take off about 1% of the charge on the surface. After that, take the voltage again. The longer a battery can hold its voltage, the better its capacity. It should be at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most frequent reason for a key fob to stop sending signals to vehicles. This issue can be fixed by replacing the battery. It is crucial to purchase an identical battery voltage and dimensions as the original.

Fobs are not indestructible and can withstand a lot. The battery contacts and buttons are delicate and are susceptible to being bent or broken by the force of.

A signal can also be interrupted by other transmitters or objects who use the same frequency. A light-control panel in your home, for instance, may interfere with key fobs using the same bandwidth. This could affect the remote control in your car.

The tool is not working properly. OBDII scan tool

There are many reasons why a scan tool may not work. Some are more complicated than others.

Professional scan tools enable mechanics to look over the car's network and perform various self-tests. These tools can save a lot of time, but they're expensive and are out of reach for the majority of DIYers.

If your OBD2 scan tool isn't turning on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, it's likely that a fuse is blowing. This is the most frequent cause of scan tool failure. It is typically easy to fix the problem by replacing the blown fuse.
