If the key fob has been exposed to water, for example a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. The best solution is to use an old towel soaked in isopropyl, or electronic cleaner.

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 in the internal electronic chip. In these situations it is possible to re-programme the key fob with an OBDII scanner might help.

Water Damage

It is possible to get water damage if your key fob was submerged in a puddle, pool or washing machine. It is usually possible to repair it by taking the batteries off and cleaning the circuit board with rubbing alcohol. It is recommended to allow the device to completely dry prior to installing the battery.

Dropping the key fob can result in this, as can water exposure. If the key fob stops functioning after exposure to water, it is possible to fix the issue by cleaning the chip using isopropyl alcohol or an electronic cleaner.

If the Key Fiat - Http://Guide08.Awardspace.Biz, fob does not respond after cleaning it it is likely that the component is damaged and will need to be replaced. A malfunctioning receiver could cause the key to stop working. This is often caused by electromagnetic interference.

Faulty electronic chip

The electronic chip in your key fob is a crucial component of the anti-theft system in your vehicle. It sends a message to the immobiliser inside your car that tells it whether the key is genuine. Your car won't start when the chip is damaged.

A defective chip can be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency near your car. In this scenario an upgrade to the fob will be needed.

Contacts of the battery may be damaged.

The battery contacts inside a key fob are very fragile and are susceptible to damage when used for long periods of time. If they are bent, or damaged, the fob will not send any signals to receiver modules in the vehicle.

Modern fobs come with rubber seals to keep out water. A splash of water or light rain should be fine, but submerging them in saltwater could harm the electronic chip.

The key fob is equipped with an electronic chip that communicates with the vehicle's immobilizer system to start it. It uses the red keys of older vehicles, or the cryptocoding system found in the latest vehicles. If the chip is not working properly and needs to be replaced.

Faulty 12 Volt Battery

A faulty battery can cause the remote to cease to function. When this happens the car's computer will not be able to recognize that the remote is in the vehicle.

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

To test the battery's power test the battery's capacity by placing an electrical load on it for a couple of minutes. This will remove about 1% of the charge on the surface. Then, you can measure the voltage. The better the battery's capacity and the longer it can keep its voltage. The ideal scenario is to keep it close to 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the main reason for the key fob not sending signals to the car. The battery can be replaced to solve this issue. However, it how much is a new fiat 500 key important to buy a new battery that is the same voltage and size as the original one.

Fobs endure a lot of abuse, but they're also not indestructible. Contacts and buttons on batteries can be damaged through rough handling.

The signal could also be impacted by other transmitters or objects that operate on the same frequency. A light-control panel in your home, for instance can interfere with key fobs that have the same frequency. This could interfere with the remote control in your car.

Afflicted OBDII Scan Tool

There are a number of reasons why a scan tool may not work. Some are more complex than others.

Professional scan tools enable mechanics to look over the car's network and run various self-tests. These are real time savers, however they can be expensive, and beyond the budget of most DIYers.

If your OBD2 scanner won't start make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine the fuse could have been blown. This is among the most common causes of scan tool failure. It is typically easy to fix the issue by replacing the fuse that has blown.
