Fiat Panda Key Fob replacement fiat 500 key

Fiat Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car to open doors or turn on the motor. The fob might stop working due to a variety of reasons.

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

Dead Coin Battery

If your key fob battery has gone out of service, the first thing to do is replace it. Use a button cell battery with the same voltage, size, and specification as your old one.

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to being used again. The best solution is to use the paper towel and soak it in isopropyl, or electronic cleaner.

If the key fob hasn't been exposed to water but isn't working, there may be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan may assist in these situations.

Water Damage

You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's possible to get it back in working order by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It's best to let the board completely dry prior to installing batteries.

If your key fob has stopped working, even after replacing the battery and changing the program, you could have a problem with the receiver module. There are instructions for reprogramming most vehicles' remote keys 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 is equipped with an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit and receive signals to the vehicle. Dropping the key fob can cause this, as well as exposure to water. If the key fob stops functioning after exposure to water, it could be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or an electronic cleaner.

If the key fob won't respond to cleaning, it is possible that the receiver module has issues and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to cease functioning. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob plays a vital part in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car to inform it whether the key is legitimate. Your car won't start in the event that the chip is damaged.

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

Contacts to the battery are not working properly.

The battery contacts in a key fob are very delicate and could be damaged when used for long periods of time. If they're bent or damaged, the fob will not transmit any signals to receiver modules in the vehicle.

Modern fobs are designed with rubber seals that keep out water. Submerging them in water, even if it's just an occasional drizzle or splash could harm the electronic chip.

The key for fiat 500 (http://xilubbs.xclub.tw/space.php?uid=238975&do=profile) fob has chips that communicate with the vehicle's immobilizer to allow it to allow it to start. It uses the old red keys that were used in older vehicles or the cryptocoding system that is used in modern vehicles. If this chip is faulty it must be replaced.

Faulty 12 Volt Battery

A damaged battery could cause the key fob to work. When this occurs the car's computer won't recognize that the remote is in the vehicle.

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly then it's time to replace it.

Put an electrical load for a short time on the battery to check its capacity. This will eliminate about 1% of the surface charge. Then, you can measure the voltage. The better the battery's capacity, the longer it can maintain its voltage. It is ideal to maintain close to 12 volts over several minutes.

Problems with Radio Signal

This is the most frequent reason for a keyfob that stops sending signals to the car. The issue can be fixed by replacing the battery. It is important to buy an identical battery voltage and dimensions as the original.

Fobs endure a lot of abuse, but they're also not indestructible. The battery buttons and the contacts are fragile which means they could be bent or damaged by excessive use.

A signal can also be interrupted by other objects or transmitters which use the same frequency. A light-control panel at your home, for example, may interfere with key fobs that use the same bandwidth. This can affect the remote control of your car.

Incorrect OBDII Scan Tool

There are a variety of reasons why a scanner tool may not perform. Certain are more complicated than others.

Professional scan tools let mechanics to look over the car's network and perform various self-tests. These are great time savers, but they are also extremely expensive and are out of the budget of most DIYers.

If your OBD2 scan tool doesn't turn on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the chances are that a fuse is blowing. This is among the most frequent causes of a scan tool failing. The easiest solution is to replace the fuse that is blowing up.
