fiat 500 key replacement Panda keyfobs are equipped with a transponder which transmits an indication from the fob to the car to unlock doors or start the motor. However, the key fob may stop working for several reasons.

A dead coin battery is the most frequent reason for the malfunction of a key fob. Other causes are water damage, a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has gone out of service. Choose a button battery that has the same voltage, size, and specifications as your previous one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it will have to be cleaned before it can be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will help.

If the key fob is not working despite not being exposed to water it could be due to a malfunction in the receiver module or internal electronic chip. Reprogramming the keyfob by using an OBDII scan could help in these instances.

Water Damage

It is possible to get water damage if your key fob was submerged in a pool, puddle or washing machine. It is usually possible to get it working again by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is best to let the board completely dry before installing a battery.

You may have a faulty module in the event that your key fob stops working after replacing the battery or updating. There are reprogramming guidelines for most vehicles' remote key fobs on YouTube or in the owner's guide. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. A key fob falling off can cause this, as could exposure to water. If the key fob stopped working after exposure to water, it could be possible to fix it by cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob does not respond to cleaning, it is likely that the module is in an issue and should be replaced. A malfunctioning receiver module could also cause the remote control key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

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

A defective chip can be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency near your car. In this situation, you will need a new key fob.

Contacts for the battery that are defective

The battery contacts on a key fob are very delicate and can get damaged through repeated use. If they're bent or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs come with rubber seals that keep out water. In the event of submerging them in water, even if it's just the slightest splash or drizzle could damage the chip's electronic components.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to start it. This system utilizes cryptocoding systems in modern vehicles and the older red key system for older ones. If the chip is not working properly and needs to be replaced.

Poor 12 Volt Battery

A defective battery can cause the remote to cease to function. When this occurs, the car's computer system cannot recognize that the remote is within the vehicle.

Before you replace the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery will read 12.6 volts. If the reading drops significantly, it is time to replace the battery.

Set an electrical load for a few seconds 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 is able to hold its voltage greater is its capacity. Ideally, it should remain at 12 volts or less for several minutes.

Faulty Radio Signal

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

Fobs take a lot of abuse, but they're not impervious to destruction. The battery buttons and contacts are brittle and are susceptible to being bent or broken by rough use.

Other transmitters or objects using the same frequency may also interfere with the signal. For instance, a light-control panel that is near your home could send interference over the same frequency that key fobs use. This could cause interference with the remote control of your car.

The tool is not working properly. OBDII scan tool

There are a number of reasons why a scanner may not work. Certain are more complicated than others.

Professional scan tools enable a mechanic observe the car's network and perform various self-tests. These can be real time savers, but they can be expensive, and out of the budget of most DIYers.

If your OBD2 scan tool won't power on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's likely that a fuse is blowing. This is the most common reason for failure of the scan tool. It is generally easy to fix the problem by replacing the fuse blowing up.
