Fiat scudo key Replacement Panda Key Fob Replacement

fiat car key replacement Panda keyfobs are equipped with a transponder, which sends signals from the fob to the car that allows it to unlock doors or start the motor. The fob might stop working for a variety of reasons.

A dead battery for the coin is the most common reason for a key fob malfunction. Other causes are water damage, a faulty receiver module and signal interference.

Dead Coin Battery

If your key fob's battery has gone out of service, the first step is to replace it. Use a new button cell battery that is the same voltage, size, and specification like the previous one.

If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it needs to be cleaned before it can 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 remains inoperable it could be due to a problem with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner can assist.

Water Damage

If your key fob's battery has taken a bath in the puddle or pool, or taken a trip down the washing machine, you could be suffering some water damage. It's usually possible to get it back in working order by taking the batteries off and cleaning the circuit board using rubbing alcohol. It's best to let the fob completely dry before installing the battery.

It could be that you have a defective module in the event that your key fob stops working after replacing the battery or changing the programming. You can find the instructions for the reprogramming of most remote keys on YouTube, or consult your owner's manual. You can also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. If this chip becomes damaged, it can no longer be able to send or receive signals to the vehicle. This can be caused by dropping the key fob, or by water exposure. If the key fob you have purchased has stopped working due to exposure to water it is possible to fix it if clean the chip using electronic cleaner or isopropyl alcohol.

However, if the key fob is still unable to not respond even after cleaning it it is likely that the module is faulty and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is often caused by electromagnetic interference.

A defective electronic chip

The electronic chip in your key fob is an important element of the anti-theft device in your car. It sends a signal to the immobiliser in your car to tell it whether the key is genuine. Your car will not start if the chip is damaged.

A malfunctioning chip can be caused by interference from objects, bad weather or transmitters close to your vehicle. In this situation you'll require a new key fob.

Faulty battery contacts

The battery contacts on the key fob could be damaged by heavy usage. If they are bent, or broken, the fob won't send any signals to the receiver modules in the vehicle.

Modern fobs are designed with rubber seals to keep out water. A splash of water or light rain is fine but submerging them into salt water could damage the chip's electronic components.

The key fob is equipped with a chip that communicates with the vehicle's immobilizer system to allow it to start. This system makes use of cryptocoding systems in the latest vehicles and the older red key system in older ones. This chip will need to be replaced if it's malfunctioning.

Faulty 12 Volt Batterie

A malfunctioning battery could cause the key fob not to function. The car's computer won't recognize the remote when this occurs.

Before you replace the battery, test it by using a an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly the time is now to replace it.

Install an electrical charge for a few seconds on the battery to check its capacity. This will eliminate about 1% of the charge on the surface. Then measure the voltage again. The longer the battery is able to hold its voltage greater is its capacity. Ideal is to hold close to 12 volts during several minutes.

Problems with Radio Signal

This is the most common reason for a key fob to stop sending signals to cars. The issue can be fixed by replacing the battery. It is however important to purchase a battery that has the same voltage and size as the original one.

Fobs aren't indestructible and can take a lot. Contacts and buttons on batteries can be damaged by rough handling.

A signal can also be disrupted by other transmitters or objects that operate on the same frequency. A light-control system in your home, for instance can interfere with key fobs that have the same bandwidth. This could affect the remote control in your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scan tool could not work. Some are more complex than others.

Professional scan tools let a mechanic observe the car's networks and run various self-tests. These tools can save a lot of time, but they're expensive and are out of reach for the majority of DIYers.

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's likely that a fuse has failed. This is among the most frequent causes of a scan tool failing. It is typically simple to fix the issue by replacing the fuse that has blown.
