10 Things Your Competitors Learn About Fiat 500 Keys
fiat 500 spare key cost uk contain an transponder chip that transmits a signal to your car to open the doors or start the engine. The fob might stop working due to a variety of reasons.
The most common cause of key fob malfunction is a dead coin battery. Other causes include water damage, an inoperative receiver module and signal interference.
Dead Coin Battery
If your key fob's battery has died, the first thing to do is replace it. Use a button cell battery with the same voltage, size and specifications as the old one.
If the key fob has been exposed to water, such as a splash of rain or salt water at the beach, it's going to need to be cleaned before it can be used again. The trick is to use the paper towel and soak it in isopropyl or electronic cleaner.
If the key fob is not working despite not being exposed 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
It is possible to get water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to allow the fob to dry completely before putting in a new battery.
You may have a faulty module if your key fob stops working after replacing the battery or reprogramming. Reprogramming instructions are available for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.
Faulty Receiver Module
The key fob is equipped with the chip that communicates the vehicle's system. If the chip is damaged, it will be unable to longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or by water exposure. If your key fob isn't working due to water exposure or water exposure, you might be able to fix it by attempting to clean the chip with electronic cleaner or isopropyl ethanol.
However, if the key fob still does not respond after cleaning it you can be sure that the module is faulty and needs to be replaced. A faulty receiver can also cause the key to not work. This is usually due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob is a vital role in the anti-theft system of your car. It transmits a message the immobiliser in your car to inform it whether the key is legitimate. If the chip is damaged or damaged, your car will not start.
A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters operating on the same frequency in close proximity to your vehicle. In this situation you'll need a new key fob.
Contacts to the battery are not working properly.
The battery contacts on the key fob could be damaged due to heavy use. If they're bent, or broken, the fob won't send any signals to the receiver modules inside the vehicle.
Modern fobs come with rubber seals to keep out water. A splash of water or a light rain should be fine, but submerging them in saltwater can damage the electronic chip.
The key fob has an electronic chip that communicates with the vehicle's immobilizer system in order to allow it to start. This system utilizes cryptocoding systems in the latest vehicles or the red key system for older models. If the chip is not working properly, it will need to be replaced.
The 12 Volt Battery is faulty
A faulty battery can cause the key fob to stop working. The car's computer may not recognize the remote when this occurs.
Test the battery with an voltmeter prior to replacing it 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.
Install an electrical charge for a few moments on the battery to determine its capacity. This will take away 1percent of the surface charges. Then, test the voltage again. The better the battery's capacity and the longer it can keep its voltage. Ideally, it will remain at 12 volts or less for several minutes.
Problems with Radio Signal
This is the main reason for a keyfob that ceases to send signals to the car. The battery could be replaced to fix this problem. It is essential to purchase a battery that has the same dimensions and voltage as the original.
Fobs are subject to a lot of punishment, and aren't indestructible. The battery buttons and the contacts are fragile and can be bent or broken with rough use.
The signal could also be affected by other objects or transmitters who use the same frequency. A light-control panel in your home, for example, may interfere with key fobs using the same frequency. This can interfere with the remote control of your car.
Incorrect OBDII scan tool
There are many reasons scanners don't function. Some are more complex than others.
Professional scan tools allow mechanics to look over the car's networks and perform a variety of self-tests. They can be huge time-savers, but they are also extremely expensive, and out of the reach of most DIYers.
If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK it could be that a fuse has failed. This is one of the most common causes of a scan tool failing. It is usually easy to fix the problem by replacing the fuse blowing up.
