fiat 500x key fob Panda Key Fob Replacement

fiat punto key fob replacement Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car in order to unlock doors or start the motor. The fob may stop working due to a variety of reasons.

The most commonly cited reason for key fob failure is the battery of the coin is dead. Other reasons include water damage, an inoperative receiver module and signal interference.

Dead Coin Battery

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

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

If the key fob has not been exposed to water but still does not work it could be an issue with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner could aid.

Water Damage

If your key fob took submerged in a puddle or pool, or taken a trip to the washing machine, it could have some water damage. It is usually possible to restore it's functionality by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is best to let the board completely dry before putting in batteries.

If your key fob stopped working even after replacing the battery and reconfiguring it, you may have a faulty receiver module. There are instructions for changing the programming of most fiat punto remote key price keys on YouTube or consult the owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. This can be caused by dropping the key fob, or by exposure to water. If the key fob has stopped functioning after exposure to water, it could be possible to fix it by cleaning the chip with isopropyl alcohol or electronic cleaner.

However, if the key fob is still unable to not respond after cleaning it there is a good chance that the module is faulty and must be replaced. A damaged receiver can cause the key to stop working. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob plays a crucial role in the anti-theft security system of your car. It sends a signal to the immobiliser unit of your vehicle to tell it whether the fiat 500 key fob not working is legitimate. Your car won't start in the event that the chip is damaged.

A defective chip could be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this case, you will need a new key fob.

Faulty battery contacts

The battery contacts on the fob's battery can be damaged by excessive usage. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs are equipped with rubber seals that block out water. Submerging them in water, even if just a light drizzle or splash can harm the chip's electronic components.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. The system relies on cryptocoding systems in the latest vehicles as well as the traditional red key system for older models. If this chip is faulty it must be replaced.

Problematic 12 Volt Battery

A malfunctioning battery could cause the key fob to cease to function. The fiat car key's computer may not recognize the remote if this happens.

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

Install an electrical charge for a short time on the battery to check its capacity. This will take away about 1% of the surface charge. Then, test the voltage again. The longer a battery can keep its voltage steady and the higher its capacity. Ideal is to hold at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

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

Fobs take a lot of abuse, and they aren't 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 system in your home, for instance can interfere with key fobs that have the same bandwidth. This could interfere with the remote control of your car.

Incorrect OBDII Scan Tool

There are a number of reasons why a scanner could not work. Some are more complicated than others.

Professional scan tools enable mechanics to look over the car's network, and run various self-tests. These are great time savers, however they are also extremely expensive, and beyond the budget of many 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 both are in good condition it's possible that a fuse has failed. This is among the most common reasons for failure of the scanner. The most straightforward fix is to replace the fuse that has been blown.
