fiat punto key programming Panda key fobs contain transponder chips that send a signal to your car to open the doors and start the engine. The fob may stop working due to a variety reasons.

The most frequent cause of key fob failure is an inoperable coin battery. Other causes include water damage, a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery if the key fob has failed. Make use of a new button battery with exactly the same size, voltage, and specification as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to using it again. The trick is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water but still does not work it could be due to 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 may aid.

Water Damage

If your key fob's battery has taken a bath in the puddle or pool, or taken a trip to the washing machine, you may have some water damage. You can usually get it working again 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 has stopped working, even after replacing the battery and programming it again, you might have a faulty receiver module. You can find the instructions for reprograming the majority of remote keys on YouTube or in the owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that communicates with the car's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or by exposure to water. If the key fob has stopped functioning after exposure to water, it may be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner.

However, if the key fob still does not respond following cleaning, you can be sure that the receiver module is not functioning properly and must be replaced. A damaged receiver can cause the key to not work. This is usually due to electromagnetic interference.

A defective electronic chip

The chip that is embedded in your key fob is an essential component of the anti-theft systems in your vehicle. It transmits a message to the immobiliser in your car to inform it that the key is valid. If the chip is damaged or broken, your car won't start.

A faulty chip may also be caused by interference from objects, bad weather or transmitters near your vehicle. In this situation it is likely that a new fob would be needed.

Contacts to the battery are not working properly.

The battery contacts of the key fob are delicate and can get damaged by repeated use. If they're bent or broken, the fob won't send any signals to receiver modules in the vehicle.

Modern fobs come with rubber seals in order to keep out water. Immersing them in water, even if it's only an occasional drizzle or splash can harm the chip's electronic circuit.

The key fob has a chip that communicates with the vehicle's immobilizer to allow it to begin it. It uses the old red keys for older vehicles or the crypto coding system in modern vehicles. This chip will have to be replaced if malfunctioning.

Faulty 12 Volt Battery

A defective battery can cause the key fob to work. The car's system will not recognize the remote if this occurs.

Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly, it is time to replace the battery.

To test the battery's power test the battery's capacity by placing an electrical load on it for a few minutes. This will eliminate about 1 percent of the surface charge. Then, you can measure the voltage. The better the battery's capacity and the longer it can keep its voltage. It should be at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for the key fob to stop sending signals to the car. This problem can be solved by replacing the battery. It is crucial to purchase a battery that has the same dimensions and voltage as the original.

Fobs are not indestructible and are susceptible to damage. The battery contacts and buttons are delicate and are susceptible to being bent or damaged from rough use.

A signal may also be impacted by other objects or transmitters which use the same frequency. A light-control panel at your home, for instance, may interfere with key fobs using the same bandwidth. This could interfere with your car's remote control.

Incorrect OBDII Scan Tool

There are a number of reasons why a scan tool might not work. Certain are more complicated than others.

Professional scan tools enable mechanics to examine the car's systems and run a variety of self-tests. These are great time-savers, but they can be expensive, and out of the budget of most DIYers.

If your OBD2 scan tool won't power on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the fuse could have ruptured. This is one of the most frequent reasons for failure of the scanner. The most straightforward fix is to replace the fuse that is blowing up.
