Fiat Panda Key Fob Replacement

fiat replacement key fob Panda key fobs contain a transponder chip which sends a signal to your car to unlock the doors or start the engine. The fob could stop working due to a variety reasons.

The most common cause of key fob failure is an inoperable coin battery. Other causes are water damage, the receiver module is defective, and signal interference.

Dead Coin Battery

Replace the battery if the key fob is dead. Use a brand new button battery with exactly the same size, voltage and specification as the original.

If the key fob has been exposed to water, for example a splash of rain or salt water at the beach, it needs to be cleaned before it can be used again. The trick is to use the paper towel and soak it in isopropyl, or electronic cleaner.

If the key fob hasn't been exposed to water, but still does not work it could be due to a problem with the receiver module or an internal electronic chip. In these instances you can reprogramme the key fob with an OBDII scanner could aid.

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 again by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob completely dry prior to installing batteries.

If your key fob has stopped working even after replacing the battery and changing the program fiat 500 key fob, you could have a malfunctioning receiver module. You can find instructions for reprogramming most vehicles' remote keys on YouTube, or consult the owner's manual. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob has the chip that communicates with the car's system. This chip will stop sending and receiving signals to the car when it is damaged. This could be due to dropping the key fob or due to exposure to water. If your key fob has stopped functioning due to water exposure it is possible to fix it if clean the chip with electronic cleaner or isopropylethanol.

However, if the key fob does not respond after cleaning it you can be sure that the module is faulty and needs to be replaced. A defective receiver can cause the key to stop working. This is usually due to electromagnetic interference.

A defective electronic chip

The electronic chip in the key fob is a vital component of the anti-theft system in your car. It sends a signal the immobiliser unit in your car to inform it whether or not the key is in fact valid. Your car will not start when the chip is damaged.

A damaged chip could be caused by interference from other objects, weather conditions or transmitters in the vicinity of your vehicle. In this situation you'll require a new key fob.

Contacts of the battery may be damaged.

The battery contacts on the key fob are fragile and are susceptible to damage when used for long periods of time. If they're bent or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.

Modern fobs come with rubber seals that block out water. Submerging them in water even if it's only an occasional drizzle or splash could harm the electronic chip.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle, allowing it to start it. This system makes use of cryptocoding systems in newer vehicles as well as the traditional red key system used in older models. If the chip is damaged it must be replaced.

The 12 Volt Battery is faulty

A malfunctioning battery could cause the key fob to cease to function. The fiat car key cutting's computer won't recognize the remote if this happens.

Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly the time is now to replace it.

To test the battery's power test the battery's capacity by placing an electrical load on it for a couple of minutes. This will eliminate about 1 percent of the surface charge. Then measure the voltage again. The longer the battery can hold its voltage and the higher its capacity. The ideal scenario is to keep it close to 12 volts for several minutes.

Problems with Radio Signal

This is the most common reason for keys not sending signals to a car. This problem can be solved by replacing the battery. But, it is essential to purchase a battery with the same voltage and size as the original.

Fobs aren't impervious to damage and can be damaged by a lot. Contacts on batteries and buttons can be damaged by rough handling.

A signal can also be affected by other objects or transmitters which use the same frequency. For instance, a light-control panel in your home could send interference over the same frequency as fiat punto key replacement fobs utilize. This can interfere with the remote control in your car.

Incorrect OBDII scan tool

There are a number of reasons why a scanner might not work. Some are more complex than others.

Professional scan tools enable mechanics to observe the car's network and perform various self-tests. These can be real time savers, but they can be expensive, and out of the budget of most DIYers.

If your OBD2 scan tool doesn't turn on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it's possible that a fuse has failed. This is among the most common causes of a scan tool failing. The simple fix is usually to replace the fuse that has been blown.
