Fiat 500 spare key cost uk Panda keyfobs are equipped with a transponder, which sends signals from the fob to the car in order to unlock doors or turn on the motor. However, the fob can stop working for several reasons.
A dead coin battery is the most frequent reason for malfunctioning fiat 500 keys. Other causes include water damages, a faulty module, and interference signals.
Dead Coin Battery
If the battery in your key fob is dead, the first thing to do is replace it. Use a button cell battery with the same voltage, size and specifications as the previous one.
If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will work wonders.
If the key fob is not working despite not being exposed to water, it could be due to a malfunction in the receiver module or internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner could aid.
Water Damage
You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's possible to fix it by getting rid of the batteries and cleaning the circuit board using ruby alcohol. It's best to let the board completely dry prior to installing batteries.
There could be a problem with the module in the event that your remote stops working after replacing the battery or changing the programming. You can find instructions for reprograming the majority of remote keys on YouTube or in your owner's manual. You can also reset your car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob contains a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. The key fob being dropped can cause this, as well as water exposure. If the key fob you have purchased has stopped working due to water exposure, you may be able fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.
However, if the key fob still does not respond after cleaning it, it is likely that the module is faulty and must be replaced. A damaged receiver module may also cause the remote control key to not function. This is usually caused by electromagnetic interference.
A defective electronic chip
The chip that is embedded in your key fob is a crucial component of the anti-theft systems in your car. It sends a message to the immobiliser inside your car to tell it that the key is valid. If the chip is damaged or broken, the car will not start.
A defective chip can be caused by interference signals from objects like bad weather conditions or transmitters on the same frequency near your fiat punto car key replacement. In this case you'll require a new key fob.
Contacts for the battery that are defective
The battery contacts of the key fob are delicate and could be damaged through repeated use. If they are damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.
Modern fobs are designed with rubber seals in order to keep out water. Immersing them in water, even if it's only an occasional drizzle or splash could damage the electronic chip.
The key fob comes with a chip which communicates with the immobilizer system of the vehicle in order to start it. The system utilizes the old red keys that were used in older vehicles or the cryptocoding system that is used in newer cars. This chip will need to be changed if it is faulty.
A faulty 12 Volt battery
A malfunctioning battery could cause the key fob not to function. The car's system will not recognize the remote if this occurs.
Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly, it is time to replace the battery.
Place an electrical load for a few seconds on the battery to determine its capacity. This will eliminate one percent of the surface charges. After that, measure the voltage. The higher the capacity of the battery and the longer it can keep its voltage. Ideal is to hold close to 12 volts over several minutes.
Faulty Radio Signal
This is the most common reason for a keyfob that ceases to send signals to the car. The battery could be replaced to fix this issue. It is however important to buy a new battery that is the same voltage and size as the original one.
Fobs aren't impervious to damage and can take a lot. The battery buttons and contacts are brittle and can be bent or broken by rough usage.
A signal can also be interrupted by other transmitters or objects that use the same frequency. For instance, a light-control panel close to your home can send interference on the same bandwidth that key fobs use. This can affect the remote control of your car.
Incorrect OBDII Scan Tool
There are many reasons why a scanner might not work. Certain are more complicated than others.
Professional scan tools enable mechanics to observe the car's network, and run various self-tests. They can be huge time savers, however they can also be very expensive, and out of the budget of many DIYers.
If your OBD2 scan tool fails to turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the fuse could have been blown. This is one of the most common causes of a scan tool failing. The easiest solution is to replace the fuse that has been blown.
