Why No One Cares About Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder which transmits a signal from the fob to the car that allows it to unlock doors or turn on the motor. However, the fob can stop working for several reasons.
The most common reason for key fob failure is a dead coin battery. Other causes are water damage or a damaged module and interference signals.
Dead Coin Battery
If your key fob's battery has gone out of service, the first step is to replace it. Use a new button cell battery that has the same size, voltage, and specification as the previous one.
If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to being used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will do the trick.
If the key fob has not been exposed to water, but still does not work, there may be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan may aid in these situations.
Water Damage
If your key fob took a bath in the pool or puddle or walked to the washing machine, you could be suffering some water damage. It's usually possible to get it back in working order by taking the batteries off and cleaning the circuit board using ruby alcohol. It is a good idea to allow the fob to dry completely prior to installing a new battery.
You could have a damaged module in the event that your remote stops working after replacing the battery or reprogramming. You can find reprogramming instructions for most remote key fobs on YouTube or in your owner's guide. You can also reset your computer of your car using the OBDII scanner tool.
thekeylab.co.uk is an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it will be unable to longer transmit and receive signals to the vehicle. The key fob being dropped can cause this, as could water exposure. If the key fob is not working after water exposure it is possible to repair the issue by cleaning or cleaning the chip using isopropyl alcohol or an electronic cleaner.
If the key fob continues to not respond following cleaning, it is likely that the component is damaged and will require to be replaced. A defective receiver can cause the key to stop working. This is typically caused by electromagnetic interference.
Electronic chip that is malfunctioning
The electronic chip in your key fob is an essential element of the anti-theft device in your car. It sends a signal to the immobiliser in your car that tells it whether the key is legitimate. If the chip is damaged or broken, your vehicle will not start.
A faulty chip can also be caused by interference signals from objects, bad weather conditions or transmitters on the same frequency near your vehicle. In this situation an upgrade to the fob will be needed.
Contacts for the battery that are defective
The battery contacts of the key fob are delicate and could be damaged with hard usage. If they're damaged or bent, the fob will not send any signals to the receiver modules in the car.
Modern fobs have rubber seals that keep out water. Immersing them in water, even if just small splash or drizzle, can damage the chip's electronic components.
The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle to start it. The system utilizes the old red keys for older vehicles as well as the crypto coding system in newer cars. If the chip is not working properly, it will need to be replaced.
Faulty 12 Volt Battery
A malfunctioning battery could cause the key fob to stop working. The car's computer won't recognize the remote if this occurs.
Before you replace the battery, test it with an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly then it's time to replace it.
Put an electrical load for a few seconds on the battery to gauge its capacity. This will remove approximately 1% of the surface charge. Then, test the voltage again. The higher the capacity of the battery and the longer it can maintain its voltage. Ideally, it should remain close to 12 volts for several minutes.
Faulty Radio Signal
This is the most common reason behind a key fob that stops sending signals to the car. The battery is able to be replaced to resolve this issue. It is crucial to buy batteries that have the same dimensions and voltage as the original.
Fobs endure a lot of abuse, but they're not impervious to destruction. The battery buttons and the contacts are fragile which means they could be bent or damaged from the force of.
Other transmitters or objects operating on the same frequency could also interfere with the signal. A light-control panel at your home, for example could interfere with key fobs that use the same frequency. This can interfere with the remote control of your car.
Afflicted OBDII scan tool
There are many reasons why a scan tool might not work. Some are more complex than others.
Professional scan tools enable mechanics to monitor the car's network and perform a variety of self-tests. These tools can save a lot of time, but are expensive and out of reach for most DIYers.
If your OBD2 scan tool doesn't turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK the fuse could have been blown. This is the most frequent cause of scan tool failure. It is generally easy to fix the problem by replacing the fuse that has blown.
