Do Not Forget Fiat 500 Keys: 10 Reasons Why You No Longer Need It

Fiat Panda Key Fob fiat doblo replacement key

fiat remote key Panda key fobs contain transponder chips that send a signal to your car to unlock the doors or start the engine. The fob might stop working due to a variety reasons.

A dead coin battery is the most common reason for key fob malfunctions. Other reasons include water damage, malfunctioning receiver modules 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 brand new button battery that has exactly the same size, voltage, and specification as the original.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned before being used again. The best method is to use an old towel soaked in isopropyl, or electronic cleaner.

If the fiat bravo key fob is not working despite not being exposed water it could be due a malfunction in the receiver module, or even in the internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner may help.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's possible to repair it by removing the batteries and cleaning the circuit board with ruby alcohol. It is recommended to let the circuit board 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. You can find instructions for the reprogramming of most remote keys on YouTube or refer to your owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. This could be due to dropping the key fob, or through exposure to water. If your fiat key case replacement fob stopped working due to water exposure and you are unable to fix it if clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob continues to not respond even after cleaning it you can be sure that the receiver module is not functioning properly and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is usually due to electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip that is in your key fob plays a vital role in the anti-theft system of your vehicle. It sends out a signal the immobiliser unit of the vehicle to determine whether the key is legitimate. Your car will not start if the chip is damaged.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this case it is likely that a new fob would be required.

Faulty Battery Contacts

The battery contacts of the fob's key can be damaged by excessive usage. If they're damaged or bent, the fob will not transmit any signals to the receiver modules in the car.

Modern fobs are constructed with rubber seals in order to keep out water. Submerging them in water, even if it's only an occasional drizzle or splash could harm the chip's electronic components.

The key fob has a chip which communicates with the immobilizer system of the vehicle in order to start it. It uses the red keys of older vehicles, or the cryptocoding system used in newer cars. If the chip is defective it must be replaced.

Faulty 12 Volt Battery

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

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

Set an electrical load for a short period of time on the battery to gauge its capacity. This will eliminate 1% of the surface charges. Then take another measurement of the voltage. The greater the battery's capacity, the longer it can keep its voltage. The ideal is to keep it close to 12 volts during several minutes.

Radio Signal Faulty Radio Signal

This is the main reason for a key fob to stop sending signals to the car. This problem can be solved by replacing the battery. However, it is important to purchase a battery that has the same voltage and size as the original one.

The buttons are not impervious to destruction and are susceptible to damage. The battery contacts and buttons could be damaged through rough handling.

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

The tool is not working properly. OBDII scan tool

There are a variety of reasons why scanners may not work. Certain are more complicated than others.

Professional scan tools enable mechanics to look over the car's networks and run a range of self-tests. These tools can save you a lot of time, but are costly and not accessible to most DIYers.

If your OBD2 scanner won't start Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK, it's likely that a fuse has failed. This is the most common reason for failure of the scan tool. The simple fix is usually to replace the blown fuse.
