replacement fiat panda keyfiat keys replacement Panda key fobs contain transponder chips that send an alert to your car to unlock the doors or start the engine. The fob may stop working for a variety.
The most common cause of key fob malfunction is the battery of the coin is dead. Other causes include water damage malfunctioning receiver modules, and signal interference.
Dead Coin Battery
Replace the battery if the key fob is dead. Choose a button battery with the same voltage, size, and specifications as the old one.
If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned prior to being used again. The best solution is to use a paper towel soaked with isopropyl or electronic cleaner.
If the key fob hasn't been exposed to water but isn't working it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan may help in these instances.
Water Damage
If your key fob took an immersion in the puddle or pool or even a trip through the washing machine, you could be suffering some water damage. It is usually possible to get it back to working by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's a good idea let the fob dry completely before putting in a new battery.
You may have a faulty module in the event that your key fob stops working after replacing the battery or changing the programming. You can find information on reprogramming most vehicles' remote keys on YouTube or consult the owner's manual. You can also reset your car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob has an electronic chip that communicates with the car's system. This chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob could result in this, as can exposure to water. If the key fob stopped functioning after exposure to water, it may be possible to fix it by cleaning the chip using isopropyl alcohol or electronic cleaner.
If the key fob does not respond to cleaning, it is possible that the module has an issue and must be replaced. A faulty receiver module can also cause the remote control key to not function. This is usually due to electromagnetic interference.
A defective electronic chip
The electronic chip inside your key fob is a crucial component of the anti-theft systems in your vehicle. It sends a signal to the immobiliser in your car to determine whether the key is legitimate. If the chip is damaged or broken, your car will not start.
A damaged chip could be caused by interference signals from objects like bad weather conditions or transmitters operating on the same frequency near your car. In this scenario an upgrade to the fob will be needed.
Contacts to the battery are not working properly.
The battery contacts of the fob's key can be damaged through heavy use. If they're damaged or bent, the key fob will not be able to send any signals to the receiver modules inside the car.
Modern fobs come with rubber seals to keep out water. A splash of water or a light rain is acceptable, but submerging them in saltwater may damage the chip's electronic components.
The key fob is equipped with a chip that communicates with the vehicle's immobilizer system in order to begin it. The system uses the red keys of older vehicles as well as the cryptocoding system found in modern vehicles. This chip needs to be changed if it is malfunctioning.
A faulty 12 Volt battery
A faulty battery can cause the key fob to cease to function. When this occurs, the car's computer system won't recognize that the remote is in the vehicle.
Before replacing the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly it's time to change it.
Install an electrical charge for a few seconds on the battery to gauge its capacity. This will eliminate 1percent of the surface charges. Then measure the voltage again. The longer the battery can hold its voltage, the better its capacity. Ideally, it should remain at or near 12 volts for several minutes.
Problems with Radio Signal
This is the most typical reason for a key fob that stops sending signals to the car. The battery can be replaced to solve this problem. However, it is crucial to purchase a battery with the same size and voltage as the original.
Fobs are subject to a lot of abuse, but they're also not impervious to destruction. The battery contacts and buttons could be damaged through rough handling.
The signal could also be interrupted by other objects or transmitters who use the same frequency. A light-control panel in your home, for example, may interfere with key fobs that have the same bandwidth. This could interfere with the remote control of your car.
Faulty OBDII Scan Tool
There are many reasons why a scan tool may not work. Some are more complex than others.
Professional scan tools let mechanics to observe the car's network and run various self-tests. These tools can save time, but they are costly and out of reach for most DIYers.
If your OBD2 scan tool won't power on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are both present it's possible that a fuse has failed. This is the main reason for failures of the scanner. The easiest solution is to replace the fuse which has blown.
