fiat doblo key fob replacement Panda key fobs contain a transponder chip that sends a signal to your car to open the doors or start the engine. However, the fob can stop working due to a variety of causes.
The most frequent cause of key fob failure is the battery of the coin is dead. Other causes are water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
Replace the battery in case your key fob has failed. Use a button cell battery with the same voltage, size, and specifications as your previous one.
If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned before being used again. A paper towel soaked in alcohol or electronic cleaner can work wonders.
If the key fob is not working despite being not exposed to water it could be due to a problem in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob with an OBDII scan can aid in these situations.
Water Damage
You might have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's usually possible to repair it by removing the batteries and cleaning the circuit board with rubbing alcohol. It is recommended to let the fob completely dry before putting in batteries.
If your key fob stopped working, even after replacing the battery and reconfiguring it, you may have a malfunctioning receiver module. You can find the instructions for reprogramming most vehicles' remote locked Keys in fiat 500 on YouTube or consult your owner's manual. You can also reset your computer in your car with the OBDII scanner tool.
Faulty Receiver Module
The key fob contains a chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob could cause this, as well as exposure to water. If the key fob has stopped working after exposure to water, it could be possible to fix it by cleaning the chip with isopropyl ethanol or electronic cleaner.
If the key fob continues to not respond after cleaning it, it is likely that the module is faulty and must be replaced. A defective receiver can cause the key to stop working. This is typically caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob plays a crucial role in the anti-theft system of your vehicle. It sends a signal the immobiliser unit in your vehicle to tell it whether the key is genuine. Your car will not start when the chip is damaged.
A malfunctioning chip can be caused by interference from objects, bad weather or transmitters close to your vehicle. In this instance you'll require a new key fob.
Contacts of the battery may be damaged.
The battery contacts on the fob's key can be damaged due to heavy use. If they are damaged or bent, the key fob won't send any signals to the receiver modules in the car.
Modern fobs come with rubber seals that keep out water. A splash of water or light rain is acceptable However, submerging them in salt water could damage the electronic chip.
The key fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. This system makes use of cryptocoding systems in newer vehicles or the red key system for older models. This chip will have to be replaced if it's malfunctioning.
The 12 Volt Battery is faulty
A faulty battery may cause the key fob to function. The car's system will not recognize the remote when this happens.
Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly the time is now to replace it.
To test the battery's capacity put an electrical load on it for a couple of minutes. This will remove 1percent of the surface charges. Then take another measurement of the voltage. The better the battery's capacity is, the longer it will keep its voltage. The ideal is to keep it close to 12 volts for several minutes.
Problems with Radio Signal
This is the main reason for a keyfob that stops sending signals to the car. The battery can be replaced to fix this problem. It is important to buy a battery with the same dimensions and voltage as the original.
Fobs aren't impervious to damage and are susceptible to damage. The battery buttons and contacts are brittle, so they can get bent or damaged by rough use.
Other transmitters or objects operating on the same frequency can disrupt a signal. For example, a light-control panel in your home could transmit interference using the same frequency as key fobs use. This can affect the remote control of your car.
Incorrect OBDII scan tool
There are a number of reasons why a scanner could not function. Some are more complicated than others.
Professional scan tools enable mechanics to observe the car's networks and run various self-tests. They can be huge time-savers, but they can be expensive, and out of the reach of most DIYers.
If your OBD2 scanner doesn't work, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's likely that a fuse has failed. This is one of the most frequent causes of failures in the scan tool. It is usually easy to fix the issue by replacing the blown fuse.
