Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends the signal to your vehicle to open the doors and start the engine. The fob might stop working for a variety of reasons.
The most frequent cause of key fob malfunction is a dead coin battery. Other causes include water damage, a faulty module, and interference signals.
Dead Coin Battery
If your key fob's battery has died, the first thing to do is replace it. Use our source that has the same size, voltage and specifications like the previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned before using again. A paper towel soaked in isopropyl alcohol or electronic cleaner can work wonders.
If the key fob has not been exposed to water, but it is still not working it could be due to a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan could assist in these situations.
Water Damage
If your key fob has gotten submerged in a puddle or pool or walked down the wash machine, it could have some water damage. It is usually possible to restore it's functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the circuit board completely dry prior to installing a battery.
You could have a damaged module if your key fob stops working after replacing the battery or changing the programming. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.
Faulty Receiver Module
The key fob's chip is an electronic chip that communicates with the car's system. This chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob can result in this, as can exposure to water. If your key fob stopped working due to water exposure or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropylethanol.
If the key fob is still unable to not respond after cleaning it, there is a good chance that the component is damaged and will need to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This is usually due to electromagnetic interference.
Electronic chip that is malfunctioning
The electronic chip that is in your key fob plays an important part in the anti-theft security system of your car. It sends a signal to the immobiliser in your car to inform it that the key is valid. If the chip is damaged or damaged, your car won't start.
A damaged chip could be caused by interference from other objects, weather conditions or transmitters close to your vehicle. In this situation an upgrade to the fob will be needed.
Contacts with the battery may be damaged.
The battery contacts inside the key fob are delicate and could be damaged with hard usage. If they are bent, or broken, the fob won't send any signals to the receiver modules inside the vehicle.
Modern fobs are designed with rubber seals to keep out water. A splash of water or a light rain is acceptable but submerging them into saltwater could cause damage to the chip's electronic components.
The key fob houses an electronic chip that communicates with the vehicle's immobilizer in order to activate it. The system uses the red keys of older vehicles, or the cryptocoding system used in modern vehicles. If the chip is damaged and needs to be replaced.
A faulty 12 Volt battery
A damaged battery could cause the key fob to function. When this happens the car's computer cannot recognize that the remote is within the vehicle.
Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls dramatically then it's time to replace the battery.
Put an electrical load for a short time on the battery to test its capacity. This will remove approximately 1 percent of the charge on the surface. After that, measure the voltage. The longer the battery is able to hold its voltage and the higher its capacity. Ideally, it should remain close to 12 volts several minutes.
Radio Signal Faulty Radio Signal
This is the most frequent reason for the key fob to stop sending signals to cars. This issue can be resolved by replacing the battery. It is important to buy a battery that has the same dimensions and voltage as the original.
Fobs are not indestructible and can withstand a lot. The battery contacts and buttons are delicate and are susceptible to being bent or broken by the force of.
Other objects or transmitters using the same frequency can disrupt a signal. A light control panel in your home, for example could interfere with key fobs which use the same bandwidth. This could interfere with the remote control of your car.
Faulty OBDII scan tool
There are many reasons why a scan tool could not work. Some are more complex than others.
Professional scan tools enable a mechanic observe the car's network, and run various self-tests. These are real time savers, however they're also expensive, and beyond the reach of 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're all fine there is a chance that a fuse has been blown. This is among the most common reasons for failure of the scanner. The easiest solution is to replace the blown fuse.
