fiat 500 replacement key Panda Key Fob Replacement

fiat stilo key Panda keyfobs are equipped with a transponder that sends an indication from the fob to the car to open doors or turn on the motor. However, the fob may be inoperable due to various reasons.

The most commonly cited reason for key fob malfunction is the battery of the coin is dead. Other causes include water damage or a damaged module and interference signals.

Dead Coin Battery

If your key fob's battery has died, the first step is to replace it. Make use of a button cell battery with the same voltage, size and specifications as your previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to using it again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can help.

If the key fob isn't working despite being not exposed to water, it could be due to a glitch in the receiver module or an internal electronic chip. In these situations it is possible to re-programme the key fob using an OBDII scanner could help.

Water Damage

If your key fob has taken immersed in a pool or puddle or walked to the washing machine, it could have some water damage. It's usually possible to restore it's functionality by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is recommended to let the fob completely dry before putting in the battery.

If your key fob stopped working, even after replacing the battery and changing the program, you could have a defective receiver module. You can find reprogramming instructions for most remote key fobs on YouTube or in your owner's guide. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. The key fob being dropped can cause this, as could water exposure. If your key fob isn't working due to water exposure, you may be able fix the issue if you clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob doesn't respond to cleaning, it is possible that the receiver module has an issue and should be replaced. A defective receiver module could also cause the remote control key to cease functioning. This is usually caused by electromagnetic interference.

Electronic chip that is malfunctioning

The chip that is embedded in your key fob is a crucial component of the anti-theft systems in your car. It sends out a signal the immobiliser unit inside the vehicle to determine whether or not the key is genuine. If the chip is damaged or broken, the car will not start.

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

Contacts to the battery are not working properly.

The battery contacts on the fob's battery can be damaged by heavy usage. If they are damaged or bent, the key fob will not send any signals to the receiver modules in the car.

Modern fobs come with rubber seals that keep out water. A splash of water or light rain is fine, but submerging them in saltwater could harm the electronic chip.

The key fob houses an electronic chip that communicates with the vehicle's immobilizer in order to begin it. The system uses the red keys of older vehicles or the cryptocoding system used in newer vehicles. This chip will have to be replaced if it's damaged.

The 12 Volt Battery is faulty

A damaged battery could cause the key fob not to function. The car's system will not recognize the remote if this happens.

Test the battery with 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.

Place an electrical load for a few seconds on the battery to check its capacity. This will take off about 1% of the charge on the surface. Then, test the voltage once more. The better the battery's capacity, the longer it can keep its voltage. It is ideal to maintain close to 12 volts over several minutes.

Radio Signal Faulty Radio Signal

This is the most typical reason for a key fob to stop sending signals to vehicles. This issue can be resolved by replacing the battery. It is crucial to purchase an identical battery voltage and dimensions as the original.

Fobs take a lot of abuse, and they aren't impervious to destruction. Contacts on batteries and buttons can be damaged by rough handling.

A signal can also be impacted by other transmitters or objects that use the same frequency. For instance, a light control panel in your home could transmit interference using the same frequency that key fobs use. This could affect the remote control of your car.

Faulty OBDII scan tool

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

Professional scan tools let mechanics to look over the car's network, and run various self-tests. These tools can save you a lot of time, but are expensive and are out of reach for 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 both present, it's likely that a fuse is blowing. This is one of the most common causes of a scan tool failing. The easiest fix is to replace the blown fuse.
