fiat van keys Panda key fobs contain transponder chips that send an alert to your car to open the doors or start the engine. However, the fob can stop working due to a variety of causes.

A dead coin battery is the most common cause of malfunctioning keys. Other reasons include water damage, a faulty receiver module and signal interference.

Dead Coin Battery

If the battery in your key fob is dead, the first thing to do is replace it. Use a button cell battery with the same voltage, size, and specification as your old one.

If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can do the trick.

If the key fob hasn't been exposed to water, but remains inoperable it could be because of a problem with the receiver module or an internal electronic chip. In these cases it is possible to re-programme the key fob using an OBDII scanner may assist.

Water Damage

If your key fob has taken a bath in the pool or puddle or gone through the washing machine, you might have some water damage. It is usually possible to get it working by removing the batteries and cleaning the circuit board with ruby alcohol. It is a good idea to let the fob dry completely before putting in a new battery.

You may have a faulty module when your fiat 124 spider key fob not working fob ceases working after replacing the battery or changing the programming. You can find the instructions for reprograming the majority of remote keys on YouTube or in your owner's manual. You can also reset your computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. The key fob being dropped can cause this, as well as water exposure. If your key fob isn't functioning due to exposure to water it is possible to fix it by attempting to clean the chip using electronic cleaner or Fiat 500 electric key isopropyl alcohol.

If the key fob is still unable to not respond following cleaning, then it is likely that the module is faulty and will need to be replaced. A faulty receiver can also cause the key to cease to function. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob plays a vital role in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car to tell it whether the key is genuine. If the chip is damaged or damaged, your car will not start.

A defective chip could be caused by interference from other objects, weather conditions or transmitters in the vicinity of your vehicle. In this case it is likely that a new fob would be needed.

Contacts with the battery may be damaged.

The battery contacts of the fob's battery can be damaged by excessive usage. If they're bent or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.

Modern fobs feature rubber seals to keep out water. A splash of water or a light rain is acceptable but submerging them into salt water could harm the electronic chip.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle to begin it. The system uses the old red keys for older vehicles as well as the cryptocoding system found in newer cars. The chip must be replaced if faulty.

Faulty 12 Volt Batterie

A damaged battery can cause the key fob to stop working. The car's computer won't recognize the remote when this happens.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly then it's time to replace the battery.

Put an electrical load for a short period of time on the battery to test its capacity. This will take off approximately 1% of the charge on the surface. Then, you can measure the voltage. The longer the battery can hold its voltage more effectively, the greater its capacity. Ideally, it should remain at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most typical reason behind a key fob that stops sending signals to the car. The battery can be replaced to fix this problem. However, it is crucial to buy a new battery that has the same size and voltage as the original.

Fobs can take a lot punishment, and aren't indestructible. The battery contacts and buttons are delicate and can be bent or damaged from the force of.

A signal can also be interrupted by other transmitters or objects which use the same frequency. For instance, a light control panel that is near your home could send interference on the same frequency as key fobs use. This can interfere with the remote control of your car.

Problems with OBDII Scan Tool

There are many reasons why a scanner tool may not work. Some are more complicated than others.

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

If your OBD2 scanner doesn't work Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK, it's likely that a fuse has blown. This is among the most common causes of a scan tool failing. The easiest solution is to replace the fuse that is blowing up.
