fiat 500x key fob replacement Panda fiat punto key replacement cost Fob replacement fiat 500 key

fiat punto key fob Panda key fobs contain an transponder chip that transmits the signal to your vehicle to unlock the doors or start the engine. The fob may stop working due to a variety reasons.

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

Dead Coin Battery

Replace the battery if your key fob has gone out of service. Use a button cell battery with the same voltage, size and specifications as the old one.

If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. The best solution is to use the paper towel and soak it in isopropyl or electronic cleaner.

If the key fob doesn't 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 through an OBDII scan could help in these cases.

Water Damage

If your key fob has taken a bath in the puddle or pool or gone down the wash machine, you may have some water damage. It's usually possible to repair it by getting rid of the batteries and cleaning the circuit board using ruby alcohol. It's best to let the fob dry completely before putting in a new battery.

If your key fob stopped working, even after replacing the battery and reprogramming it, you may have a problem with the receiver module. You can find the instructions for changing the programming of most remote fiat punto keys on YouTube, or consult your owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer be able to send or receive signals to the vehicle. The key fob being dropped can cause this, as can water exposure. If the spare key fiat 500 fob stopped working after water exposure it could be possible to repair it by cleaning the chip using isopropyl alcohol or an electronic cleaner.

If the key fob does not respond to cleaning, it is possible that the component has an issue and should be replaced. A defective receiver module could also cause the remote control key to not function. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is a vital role in the anti-theft security system in your car. It sends a signal the immobiliser unit inside your car to inform it whether the key is valid. The car will not start when the chip is damaged.

A faulty chip may also be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this instance you'll need a new key fob.

Faulty Battery Contacts

The battery contacts on the fob's key can be damaged through heavy use. If they're damaged or bent, the fob will not send any signals to the receiver modules in the car.

Modern fobs are made with rubber seals that keep out water. Submerging them in water even if it is just a light drizzle or splash could damage the electronic chip.

The key fob is equipped with chip that communicates with the immobilizer system of the vehicle, allowing it to start it. The system uses the old red keys that were used in older vehicles or the cryptocoding system found in newer cars. If the chip is not working properly it must be replaced.

Problematic 12 Volt Battery

A faulty battery may cause the key fob to work. The car's computer will not recognize the remote if this occurs.

Before you replace the battery, you should test it with a a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly then it's time to replace the battery.

Set an electrical load for a short time on the battery to check its capacity. This will remove 1% of the surface charges. Then measure the voltage again. The better the battery's capacity and the longer it can maintain its voltage. Ideal is to hold close to 12 volts during several minutes.

Problems with Radio Signal

This is the most common reason for keys not sending signals to vehicles. The issue can be fixed by replacing the battery. It is important to buy a battery with the same dimensions and voltage as the original.

Fobs aren't impervious to damage and can be damaged by a lot. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with rough usage.

A signal can also be interrupted by other objects or transmitters that operate on the same frequency. A light-control system in your home, for instance, may interfere with key fobs which use the same frequency. This can interfere with the remote control of your car.

Afflicted OBDII scan tool

There are many reasons why a scan tool could not function. Some are more complicated than others.

Professional scan tools allow a mechanic to examine the car's systems and run a range of self-tests. These tools can save a lot of time, but they are costly and not accessible to most DIYers.

If your OBD2 scan tool fails to turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're all fine the fuse could have been blown. This is the most common cause of scan tool failure. It is usually simple to fix the issue by replacing the blown fuse.
