fiat Grande Punto key Panda Key Fob replacement fiat 500 key fob

fiat 500 spare key cut Panda key fobs contain an transponder chip that transmits signals to your car to open the doors or start the engine. However, the fob could not function due to a variety of reasons.

A dead coin battery is the most common cause of a key fob malfunction. Other reasons include water damage, an inoperative receiver module, and signal interference.

Dead Coin Battery

Replace the battery if the key fob has failed. Use a button cell battery that has the same voltage, size and specifications as your previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned before using again. The best method is to use a paper towel that has been soaked in isopropyl or an electronic cleaner.

If the key fob is not working even though it is not exposed to water it could be due a malfunction in the receiver module or internal electronic chip. Reprogramming the keyfob using an OBDII scan could aid in these situations.

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 fix it by removing the batteries and cleaning the circuit board with rubbing alcohol. It is best to allow the device to completely dry prior to installing a battery.

It could be that you have a defective module if your key fob stops working after replacing the battery or reprogramming. You can find the instructions for the reprogramming of most remote keys on YouTube or consult the owner's manual. You can also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with the chip that communicates the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob could cause this, as well as water exposure. If your key fob stopped working due to water exposure and you are unable to fix it if clean the chip using electronic cleaner or isopropylethanol.

However, if the key fob is still unable to not respond even after cleaning it then it is likely that the component is damaged and needs to be replaced. A defective receiver module could also cause the remote control key to stop working. This is usually caused by electromagnetic interference.

A defective electronic chip

The chip inside your key fob plays an important part in the anti-theft security system in your car. It sends out a signal the immobiliser unit of your car to determine whether or not the key is in fact valid. If the chip is damaged or broken, your vehicle will not start.

A defective chip can be caused by interference signals from other objects or weather conditions that are bad, or transmitters operating on the same frequency as your car. In this situation you'll need a fiat 500 new key cost uk key fob.

Contacts to the battery are not working properly.

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

Modern fobs feature rubber seals that block out water. Immersing them in water, even if it's only small splash or drizzle can harm the electronic chip.

The key fob has an electronic chip that communicates with the immobilizer system of the vehicle to begin it. The system uses the red keys of older vehicles as well as the crypto coding system in newer cars. If this chip is faulty and needs to be replaced.

Problematic 12 Volt Battery

A malfunctioning battery could cause the remote to stop working. The car's computer won't recognize the remote when this occurs.

Before replacing the battery, test it by using a the voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly then it's time to replace it.

Place an electrical load for a short time on the battery to gauge its capacity. This will remove one percent of the surface charges. After that, take the voltage once more. The higher the capacity of the battery is, the longer it will maintain its voltage. Ideal is to hold close to 12 volts during several minutes.

Faulty Radio Signal

This is the most common reason for a key fob to stop sending signals to the car. This issue can be fixed by replacing the battery. It is crucial to buy a battery that has the same voltage and dimensions as the original.

Fobs can take a lot abuse, but they're also not impervious to destruction. Contacts on batteries and buttons can be damaged by rough handling.

Other transmitters or objects operating on the same frequency can disrupt the signal. For example, a light-control panel in your home could send interference over the same frequency that fiat 500 key fobs use. This could interfere with the remote control of your car.

Problems with OBDII Scan Tool

There are many reasons scanners don't work. Some are more complex than others.

Professional scan tools enable mechanics to monitor the car's network, and run various self-tests. These are great time-savers, but they are also extremely expensive and are out of the range of most DIYers.

If your OBD2 scan tool fails to turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present it's possible that a fuse is blowing. This is the most frequent reason for failures of the scanner. The easiest solution is to replace the fuse that is blowing up.
