fiat 500 replacement remote key Cost fiat panda key fob replacement Key Fob Replacement

fiat bravo key Panda key fobs contain an transponder chip that transmits the signal to your vehicle to open the doors and start the engine. However, the fob can be inoperable due to various reasons.

The most commonly cited reason for key fob failure is an inoperable coin battery. Other reasons include water damage, malfunctioning receiver modules and signal interference.

Dead Coin Battery

If the battery in your key fob is dead, the first thing to do is replace it. 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 a splash of rain or salt water at the beach, it will need to be cleaned before it is able to be used again. The best method is to use a paper towel soaked with isopropyl or electronic cleaner.

If the key fob isn't working even though it is not exposed to water it could be due a malfunction in the receiver module or in the internal electronic chip. In these situations you can reprogramme the key fob using an OBDII scanner could assist.

Water Damage

If your key fob has taken submerged in a puddle or pool, or taken a trip down the washing machine, you may have some water damage. It's usually possible to get it working again by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to allow the device to completely dry before installing the battery.

You may have a faulty module in the event that your remote stops working after replacing the battery or replacing it with. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. If the chip is damaged, it cannot longer transmit and receive signals to the vehicle. Dropping the key fob could cause this, as could exposure to water. If the key fob has stopped working after exposure to water, it is possible to fix the issue by cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob still does not respond after cleaning it you can be sure that the component is damaged and needs to be replaced. A defective receiver module could also cause the remote control key to not function. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in your key fob is an important component of the anti-theft system in your car. It sends a signal the immobiliser unit of your car to determine whether or not the fiat key fobs is legitimate. Your car will not start if the chip is damaged.

A faulty chip can also be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency close to your car. In this scenario you'll require an entirely new key fob.

Faulty Battery Contacts

The battery contacts inside the key fob are delicate and may be damaged by repeated use. If they are bent or broken the fob will not send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals that keep out water. In the event of submerging them in water, even if it's only the slightest splash or drizzle could harm the chip's electronic circuit.

The key fob has an embedded chip that communicates to the immobilizer system of the vehicle to start it. It uses the old red fiat punto keys that were used in older vehicles, or the crypto coding system in the latest vehicles. If the chip is not working properly, it will need to be replaced.

Problems with 12 Volt Batteries

A damaged battery can cause the key fob to cease to function. When this happens the car's computer cannot recognize that the remote is in the vehicle.

Before replacing the battery, test it with an voltmeter to gauge its capacity. A fully charged battery will read 12.6 volts. If the reading drops dramatically the time is now to replace it.

To test a battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away 1% of the surface charges. Then, you can measure the voltage. The greater the battery's capacity, the longer it can maintain its voltage. Ideal is to hold close to 12 volts over several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for a keyfob that ceases to send signals to the car. The battery could be replaced to fix this problem. However, it is crucial to purchase a battery that is the same voltage and size as the original.

Fobs are subject to a lot of abuse, and they aren't indestructible. Contacts and buttons on batteries can be damaged through rough handling.

Other transmitters or objects using the same frequency could also interfere with the signal. A light-control panel at your home, for instance can interfere with key fobs which use the same frequency. This could affect the fiat punto remote key replacement control of your car.

Problems with OBDII Scan Tool

There are a number of reasons why a scan tool might not work. Certain are more complicated than others.

Professional scan tools enable mechanics to monitor the car's network and run a variety 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 both are in good condition it could be that a fuse has ruptured. This is the most common cause of scan tool failure. The simple fix is usually to replace the fuse that has been blown.
