you could check here, Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car to unlock doors or start the motor. However, the fob may stop working due to a variety of causes.
The most common cause of key fob failure is the battery of the coin is dead. Other causes include water damage or a malfunctioning module and interference signals.
Dead Coin Battery
Replace the battery if your key fob has died. Use a new button cell battery that has identical in size, voltage and specification as the old one.
If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it will need 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 be the solution.
If the key fob has not been exposed to water, but it is still not working it could be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan may help in these cases.
Water Damage
You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually get it working again by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is a good idea to allow the fob to dry completely before putting in a brand new battery.
If your key fob isn't working even after replacing the battery and programming it again, you might have a defective receiver module. You can find the instructions for changing the programming of most remote keys on YouTube or refer to 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 contains a chip that connects to the car's system. If the chip is damaged, it will be unable to longer be able to send or receive signals to the vehicle. Dropping the key fob can cause this, as well as exposure to water. If the key fob is not working after exposure to water it could be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol, or electronic cleaner.
If the key fob does not respond to cleaning,

Fiat Car Keys Cut must be replaced. A faulty receiver module can also cause the remote control key to not function. This is usually due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip inside the key fob is a crucial component of the anti-theft system in your car. It transmits a message to the immobiliser inside your car to determine whether the key is genuine. If the chip is damaged or broken, your vehicle will not start.
A faulty chip may also be caused by interference caused by objects, bad weather or transmitters close to your vehicle. In this situation, you will need a new key fob.
Contacts for the battery that are defective
The battery contacts on a key fob are very delicate and could be damaged when used for long periods of time. If they are bent, or damaged, the fob will not send any signals to the receiver modules inside the vehicle.
Modern fobs are designed with rubber seals that keep out water. Submerging them in water, even if it's just small splash or drizzle could harm the chip's electronic components.
The key fob contains chips that communicate with the vehicle's immobilizer in order to activate it. This system utilizes cryptocoding systems in newer vehicles or the red key system used in older ones. If the chip is defective and needs to be replaced.
Faulty 12 Volt Batterie
A faulty battery can cause the key fob to stop working. If this happens, the car's computer system will not recognize that the remote is inside the vehicle.
Before replacing the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading falls dramatically, it is time to replace the battery.
Set an electrical load for a short time on the battery to gauge its capacity. This will take off approximately 1% of the surface charge. Then, you can measure the voltage. The longer a battery is able to hold its voltage and the higher its capacity. Ideally, it should remain at 12 volts or less for several minutes.
Problems with Radio Signal
This is the most frequent reason for a key fob that ceases to send signals to the car. This issue can be resolved by replacing the battery. However, it is crucial to purchase a battery with the same size and voltage as the original.
Fobs are not indestructible and can withstand a lot. Battery contacts and buttons can be damaged by rough handling.
A signal can also be affected by other transmitters or objects that operate on the same frequency. A light-control panel at your home, for instance can interfere with key fobs which use the same frequency. This can interfere with your car's remote control.
Faulty OBDII scan tool
There are many reasons why scanner tools may not work. Some are more complicated than others.
Professional scan tools allow a mechanic to observe the car's networks and run a variety of self-tests. These tools can save a lot of time, but they are costly and not accessible to the majority of DIYers.
If your OBD2 scanner doesn't work make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're all fine it could be that a fuse has ruptured. This is the most typical reason for a scan tool to fail. The simple fix is usually to replace the fuse that is blowing up.
