fiat 500 spare key cut Panda key fobs contain a transponder chip that sends signals to your car to open the doors or start the engine. The fob might stop working due to a variety of reasons.

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

Dead Coin Battery

If your key fob's battery is dead, the first step is to replace it. Choose a new button battery that has the same voltage, size and specifications as the original.

If the key fob was exposed to water, for example 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 isopropyl alcohol or electronic cleaner can help.

If the key fob has not been exposed to water but it is still not working it could be an issue with the receiver module or an internal electronic chip. In these situations you can reprogramme the key fob using an OBDII scanner might 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 possible to fix it by taking the batteries off and cleaning the circuit board using rubbing alcohol. It is best to let the fob completely dry prior to installing the battery.

You could have a damaged module when your key fob ceases working after replacing the battery or changing the programming. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in your owner's guide. You could also try resetting the fiat 500 car key replacement's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip that connects to the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. The fiat key replacement cost fob being dropped can cause this, as can exposure to water. If the key fob stops working after water exposure it could be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob does not respond after cleaning it, then it is likely that the component is damaged and will need to be replaced. A malfunctioning receiver could cause the key to not work. This is often caused by electromagnetic interference.

Electronic chip that is malfunctioning

The chip that is embedded in your key fob is an important component of the anti-theft systems in your vehicle. It sends a signal the immobiliser unit of your car to inform it whether the key is in fact valid. If the chip is damaged or broken, the car will not start.

A damaged chip could be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency as your car. In this situation it is likely that a new fob would be needed.

Contacts for the battery that are defective

The battery contacts in a key fob are very delicate and may be damaged by repeated use. If they are bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs are made with rubber seals to keep out water. Submerging them in water even if it is just small splash or drizzle could harm the chip's electronic components.

The key fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle to start it. This system uses crypto coding systems in newer vehicles and the older red key system in older models. If the chip is defective, it will need to be replaced.

Faulty 12 Volt Battery

A defective battery can cause the key fob not to function. The car's computer may 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 decreases significantly then it's time to replace the battery.

To test the battery's capacity to determine its capacity, put an electric load on it for a couple of minutes. This will remove approximately 1 percent of the surface charge. Then, you can measure the voltage once more. The longer a battery is able to keep its voltage steady and the higher its capacity. Ideal is that it stays close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. It is crucial to purchase a battery that has the same voltage and dimensions as the original.

Fobs aren't impervious to damage and are susceptible to damage. The battery buttons and contacts are delicate and can be bent or damaged from rough usage.

Other transmitters or objects using the same frequency can also disrupt the signal. A light-control panel at your home, for instance could interfere with key fobs which use the same frequency. This could affect the remote control of your car.

The tool is not working properly. OBDII scan tool

There are a number of reasons why a scan tool might not work. Certain are more complicated than others.

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

If your OBD2 scan tool doesn't turn on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the fuse could have ruptured. This is the most typical reason for failure of the scan tool. The most straightforward fix is to replace the fuse that is blowing up.
