fiat ducato key fob Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends a signal to your car to open the doors and start the engine. The fob can stop functioning due to a variety of reasons.
The most common reason for key fob malfunction is a dead coin battery. Other causes include water damage malfunctioning receiver modules and signal interference.
Dead Coin Battery
If your key fob's battery has died, 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 was exposed to water (such as rain or saltwater at the beach) It must be cleaned prior to being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can do the trick.
If the key fob has not been exposed to water but isn't working it could be due to a problem with the receiver module or an internal electronic chip. In these situations, reprogramming the fiat 500 spare key cut fob with an OBDII scanner may help.
Water Damage
There could be water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to get it working by getting rid of the batteries and cleaning the circuit board with ruby alcohol. It is a good idea to allow the fob to dry completely before putting in a brand new battery.
It could be that you have a defective module if your key fob stops working after replacing the battery or replacing it with. You can find instructions for reprogramming most vehicles' remote fiat van keys on YouTube or in your owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.
Faulty Receiver Module
The key fob's chip is the chip that communicates with the car's system. If the chip is damaged, it will be unable to longer transmit and receive signals to the vehicle. A key fob falling off can cause this, as can water exposure. If the key fob stops working after exposure to water, it is possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or an electronic cleaner.
However, if the key fob still does not respond even after cleaning it then it is likely that the module is faulty and must be replaced. A damaged receiver can cause the key to cease to function. This is usually due to electromagnetic interference.
Faulty Electronic Chip
The chip inside your key fob plays a vital role in the anti-theft system of your vehicle. It sends a message to the immobiliser inside your car that tells it if the fiat doblo key fob programming is valid. Your car won't start in the event that the chip is damaged.
A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency near your vehicle. In this scenario you'll need a new key fob.
Faulty Battery Contacts
The battery contacts on a key fob are very delicate and may be damaged through repeated use. If they're broken or bent, the fob will not transmit any signals to the receiver modules in the car.
Modern fobs come with rubber seals that block out water. Submerging them in water even if just small splash or drizzle could harm the electronic chip.
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 that is used in newer vehicles. If this chip is faulty, it will need to be replaced.
Problems with 12 Volt Batteries
A defective battery can cause the remote to stop working. The car's computer will not recognize the remote if this occurs.
Before you replace the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly the time is now to replace it.
To test the battery's capacity to determine its capacity, put an electric load on it for a couple of minutes. This will eliminate one percent of the surface charges. After that, measure the voltage. The longer the battery is able to keep its voltage steady greater is its capacity. Ideal is to hold at or near 12 volts 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. The issue can be fixed by replacing the battery. But, it is essential to purchase a battery with the same voltage and size as the original one.
The buttons are not impervious to destruction and can withstand a lot. The battery buttons and the contacts are fragile and are susceptible to being bent or damaged from rough usage.
Other transmitters or objects operating on the same frequency could also disrupt a signal. For instance, a light-control panel close to your home can send interference on the same frequency as key fobs utilize. This could affect the remote control of your car.
Problems with OBDII Scan Tool
There are many reasons scanners may not function. Some are more complex than others.
Professional scan tools let mechanics to monitor the fiat car keys's network and run various self-tests. These are real time savers but they are also extremely expensive, out of the budget of many DIYers.
If your OBD2 scan tool won't power on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK, a fuse may have ruptured. This is among the most common reasons for failure of the scanner. The easiest fix is to replace the blown fuse.
