fiat multipla key Panda key fobs contain a transponder chip which sends a signal to your car to unlock the doors or start the engine. However, the fob may stop working due to a variety of causes.

The most common reason for key fob malfunction is a dead coin battery. Other causes include water damage an inoperative receiver module and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has failed. Make use of a button cell battery that has the same voltage, size, and specifications as the old one.

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 best method is to use a paper towel that has been soaked in isopropyl or an electronic cleaner.

If the key fob hasn't been exposed to water, but isn't working it could be because of an issue with the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob using an OBDII scanner might aid.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the board completely dry before putting in the battery.

You may have a faulty module when your key fob ceases working after replacing the battery or reprogramming. You can find reprogramming instructions for most vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. Dropping the key fob could cause this, as could water exposure. If the fiat multipla key fob stopped working after exposure to water it is possible to fix the issue by cleaning the chip with isopropyl alcohol or electronic cleaner.

However, if the key fob still does not respond after cleaning it, there is a good chance that the module is defective and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in your key fob is a crucial component of the anti-theft system in your vehicle. It sends a signal to the immobiliser in your car to determine if the key is valid. The car will not start when the chip is damaged.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this scenario you'll need an entirely new key fob.

Contacts for the battery that are damaged

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

Modern fobs have rubber seals that keep out water. A splash of water or light rain is acceptable but submerging them into saltwater can cause damage to the chip's electronic components.

The key fob comes with an embedded chip that communicates to the immobilizer system of the vehicle to start it. This system makes use of cryptocoding systems in newer vehicles or the red key system in older models. This chip will need to be replaced if it's malfunctioning.

Faulty 12 Volt Batterie

A damaged battery can cause the key fob to stop working. When this happens, the car's computer system cannot recognize that the remote is within the vehicle.

Before replacing the battery, test it with an voltmeter for determining its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly it's time to change it.

To test a battery's capacity put an electrical load on it for a couple of minutes. This will eliminate approximately 1 percent of the charge on the surface. Then, measure the voltage once more. The longer the battery is able to hold its voltage more effectively, the greater its capacity. Ideally, it should remain close to 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the main reason for the key fob to stop sending signals to a car. The battery could be replaced to fix this problem. It is essential to purchase a battery with the same voltage and dimensions as the original.

Fobs can take a lot punishment, and aren't impervious to destruction. The battery buttons and contacts are brittle, so they can get bent or damaged by rough usage.

A signal can also be disrupted by other transmitters or objects which use the same frequency. For instance, a lighting control panel that is near your home could transmit interference using the same frequency as key fobs utilize. This could cause interference with the remote control of your car.

The tool is not working properly. OBDII scan tool

There are a variety of reasons why scanners may not perform. Certain are more complicated than others.

Professional scan tools permit mechanics to examine the car's systems and conduct a variety self-tests. These tools can save a lot of time, but are expensive and not accessible to most DIYers.

If your OBD2 scanner won't start Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape it's possible that a fuse has failed. This is the main cause of scan tool failure. It is generally easy to fix the issue by replacing the fuse that was blown.
