fiat keys Panda keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car in order to unlock doors or start the motor. However, the fob could be inoperable due to various reasons.
The most common reason for key fob failure is an inoperable coin battery. Other causes include water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
Replace the battery in case your key fob has died. Make use of a button cell battery that has the same voltage, size and specifications as the previous one.
If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned before being used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can help.
If the key fob isn't working despite not being exposed water, it could be due to a problem in the receiver module or internal electronic chip. In these situations you can reprogramme the key fob using an OBDII scanner may assist.
Water Damage
It is possible to get water damage if your fiat punto key replacement cost fob was submerged in a pool, puddle or washing machine. It is usually possible to get it back to working by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to allow the fob to dry completely before installing a new battery.
If your key fob has stopped working, even after replacing the battery and changing the program, you could have a problem with the receiver module. Reprogramming instructions are available for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset your computer of your car using the OBDII scanner tool.
Faulty Receiver Module
The key fob contains the chip that communicates with the car's system. If the chip is damaged, it cannot longer transmit or receive signals to the vehicle. A key fob falling off can result in this, as can water exposure. If your key fob has stopped functioning due to exposure to water and you are unable to fix it if you clean the chip with electronic cleaner or isopropyl alcohol.
If the key fob continues to not respond after cleaning it it is likely that the module is faulty and will need to be replaced. A damaged receiver can cause the key to cease to function. This is usually caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip in your key fob is a crucial element of the anti-theft device in your vehicle. It sends a message to the immobiliser in your spare car key Fiat 500 to determine whether the key is genuine. Your car will not start when the chip is damaged.
A defective chip could be caused by interference from objects, bad weather or transmitters near your vehicle. In this case it is likely that a new fob would be needed.
Contacts of the battery may be damaged.
The battery contacts on the fob's key can be damaged by heavy usage. If they're damaged or bent, the key fob will not transmit any signals to the receiver modules inside the car.
Modern fobs come with rubber seals that block out water. A splash of water or a light rain is fine but submerging them into saltwater could cause damage to the chip's electronic components.
The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle to start it. It uses the old red keys for older vehicles or the cryptocoding system found in modern vehicles. This chip will need to be replaced if malfunctioning.
Faulty 12 Volt Batterie
A malfunctioning battery could cause the remote to cease working. The car's computer will not recognize the remote if this happens.
Before replacing the battery, test it using 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.
To test a battery's capacity put an electrical load on it for a few minutes. This will take away approximately 1% of the surface charge. Then measure the voltage again. The better the battery's capacity is, the longer it will keep its voltage. It is ideal to maintain close to 12 volts for several minutes.
Problems with Radio Signal
This is the main reason for the key fob not sending signals to cars. This issue can be fixed by replacing the battery. But, it is essential to buy a new battery that has the same size and voltage as the original one.
Fobs aren't indestructible and can withstand a lot. Contacts and buttons on batteries can be damaged by rough handling.
Other transmitters or objects using the same frequency can also disrupt a signal. A light-control system in your home, for example can interfere with key fobs using the same frequency. This could affect your car's remote control.
Afflicted OBDII Scan Tool
There are a number of reasons why a scanner might not work. Some are more complicated than others.
Professional scan tools allow a mechanic to look over the car's networks and perform a variety of self-tests. They can be huge time savers, however they can be expensive, out of the budget of many DIYers.
If your OBD2 scan tool fails to turn on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape, it's likely that a fuse has been blown. This is the most common reason for failure of the scan tool. It is typically easy to fix the problem by replacing the fuse that has blown.
