10 Things Your Competitors Can Teach You About Fiat 500 Keys
fiat key cover contain an transponder chip that transmits a signal to your car to open the doors or start the engine. The fob can stop functioning due to a variety of reasons.
A dead battery for the coin is the most frequent cause of key fob malfunctions. Other causes include water damage a faulty receiver module, and signal interference.
Dead Coin Battery
Replace the battery if your key fob is dead. Use a brand new button battery that is the same voltage, size, and specification like the previous 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 method is to use a paper towel that has been soaked in isopropyl or an electronic cleaner.
If the key fob hasn't been exposed to water but remains inoperable it could be a problem with the receiver module or an internal electronic chip. In these instances it is possible that reprogramming the key fob with an OBDII scanner can help.
Water Damage
If your key fob's battery has taken submerged in a puddle or pool, or taken a trip to the washing machine, you might have some water damage. It's possible to repair it by taking out the batteries and cleaning the circuit board with rubbing alcohol. It's a good idea to allow the fob to dry completely before installing a new battery.
You could have a damaged module in the event that your key fob stops working after replacing the battery or updating. You can find reprogramming procedures for the majority of vehicles' remote key fobs 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 contains a chip that communicates with the vehicle's system. If this chip becomes damaged, it can no longer transmit or receive signals to the vehicle. Dropping the key fob could cause this, as can water exposure. If your key fob has stopped working due to exposure to water or water exposure, you might be able fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.
However, if the key fob does not respond following cleaning, you can be sure that the component is damaged and must be replaced. A defective receiver can cause the key to not work. This is usually due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip inside your key fob is a vital function in the anti-theft security system of your vehicle. It sends a signal to the immobiliser inside your car to inform it whether the key is genuine. If the chip is damaged or broken, your vehicle won't start.
A malfunctioning chip can be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this scenario the replacement fob will be needed.
Contacts for the battery that are damaged
The battery contacts on the key fob are fragile and are susceptible to damage by repeated use. If they're damaged or bent, the key fob will not be able to send any signals to the receiver modules in the car.
Modern fobs come with rubber seals that block out water. A splash of water or a light rain should be fine However, submerging them in saltwater may harm the chip's electronic components.
The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. This system uses crypto coding systems in modern vehicles as well as the traditional red key system for older models. If this chip is faulty, it will need to be replaced.
Faulty 12 Volt Batterie
A defective battery can cause the key fob not to work. The car's computer will not recognize the remote when this happens.
Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading decreases significantly then it's time to replace the battery.
To test the battery's power, place an electrical load on it for a couple of minutes. This will take away 1% of the surface charges. Then, you can measure the voltage again. The longer the battery is able to keep its voltage steady more effectively, the greater its capacity. The ideal scenario is to keep it at 12 volts or less for several minutes.
Faulty Radio Signal
This is the most common reason for a key fob that ceases to send signals to the car. The battery could be replaced to fix this problem. It is important to buy a battery that has the same dimensions and voltage as the original.
The buttons are not impervious to destruction and can withstand a lot. The battery contacts and buttons are delicate and can be bent or broken with the force of.
Other transmitters or objects that use the same frequency may also interfere with the signal. A light control panel in your home, for instance could interfere with key fobs that use the same bandwidth. This could interfere with the remote control of your car.
The tool is not working properly. OBDII scan tool
There are many reasons why scanner tools may not function. Some are more complex than others.
Professional scan tools let mechanics to observe the car's network and perform various self-tests. They can be huge time savers, however they are also extremely expensive, out of the budget of many DIYers.
If your OBD2 scan tool fails to turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are OK the chances are that a fuse has been blown. This is the main reason for a scan tool to fail. It is usually easy to fix the issue by replacing the fuse that has blown.
