fiat 500 key not working Panda keyfobs are equipped with a transponder that sends signals from the fob to the car Where To Get A Fiat Key Cut open doors or start the motor. The fob could stop working due to a variety reasons.

A dead battery for the coin is the most common cause of malfunctioning keys. Other causes include water damage as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery if your key fob has failed. Make use of a new button battery that has identical in size, voltage and specifications as the original.

If the key fob has been exposed to water, like a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will do the trick.

If the key fob has not been exposed to water, but still does not work it could be because of a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan can aid in these situations.

Water Damage

If your spare key for fiat 500 fob has gotten a bath in the puddle or pool or even a trip down the wash machine, you might have some water damage. It is usually possible to get it back to working by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It’s a good idea allow the fob to dry completely before putting in a new battery.

If your key fob stopped working even after replacing the battery and programming it again, you might have a malfunctioning receiver module. You can find information on reprogramming most vehicles’ remote keys on YouTube or in your owner’s manual. You can also try resetting the car’s onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that connects to the car’s system. If the chip is damaged, it can no longer send and receive signals to the vehicle. This could be due to dropping the key fob, or by exposure to water. If your key fob has stopped functioning due to exposure to water it is possible fix the issue if you clean the chip with electronic cleaner or isopropyl alcohol.

However, if the key fob continues to not respond after cleaning it it is likely that the module is defective and needs to be replaced. A malfunctioning receiver could cause the key to not work. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential part of the anti-theft system in your car. It transmits a message the immobiliser in your car to determine whether the key is genuine. The car won’t start when the chip is damaged.

A malfunctioning chip could be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency as your car. In this instance it is likely that a new fob would be required.

Contacts of the battery may be damaged.

The battery contacts of the key fob could be damaged by excessive usage. If they’re bent or damaged, the fob will not send any signals to the receiver modules inside the vehicle.

Modern fobs have rubber seals that block out water. Submerging them in water, even if it’s only the slightest splash or drizzle could harm the electronic chip.

The key fob houses an electronic chip that communicates with the vehicle’s immobilizer in order to allow it to start. The system relies on cryptocoding systems in modern vehicles or the red key system for older models. If the chip is not working properly, it will need to be replaced.

Problems with 12 Volt Batteries

A faulty battery can cause the remote to stop working. If this happens the car’s computer will not be able to recognize that the remote is in the vehicle.

Before you replace the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly then it’s time to replace the battery.

Place an electrical load for a few seconds on the battery to determine its capacity. This will remove one percent of the surface charges. Then, you can measure the voltage. The longer the battery can keep its voltage steady more effectively, the greater its capacity. The ideal is to keep it at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most typical cause of a key fob that ceases to send signals to the car. The battery can be replaced to fix this issue. It is important to buy a battery that has the same voltage and dimensions as the original.

Fobs take a lot of abuse, but they’re also not indestructible. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with rough use.

Other objects or transmitters using the same frequency could also disrupt the signal. For instance, a lighting control panel that is near your home could send interference over the same frequency that key fobs utilize. This can interfere with the remote control in your car.

Incorrect OBDII scan tool

There are many reasons why scanners don’t function. Some are more complicated than others.

Professional scan tools enable mechanics to observe the car’s network and run various self-tests. These tools can save time, but they are costly and are out of reach for most DIYers.

If your OBD2 scanner isn’t turning on examine the voltage at 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 among the most frequent causes of a scan tool failing. The easiest fix is to replace the fuse that has been blown.
