fiat punto key fob Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car to unlock doors or start the motor. The fob might stop working due to a variety of reasons.

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

Dead Coin Battery

Replace the battery if your key fob is dead. Choose a new button battery with identical in size, voltage, and specification as the original.

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 the paper towel and soak it in isopropyl, or electronic cleaner.

If the key fob hasn't been exposed to water but still does not work, there may be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan could help in these instances.

Water Damage

If your key fob has taken immersed in a pool or puddle or even a trip down the washing machine, it could have some water damage. It is usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the circuit board completely dry before installing the battery.

If your key fob isn't working even after replacing the battery and programming it again, you might have a problem with the receiver module. You can find reprogramming procedures for most remote key fobs on YouTube or in the owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the car's system. This chip will stop sending and receiving signals to the car key Maker if damaged. This could be due to dropping the key fob or by water exposure. If the key fob you have purchased has stopped working due to exposure to water or water exposure, you might be able to fix it by attempting to clean the chip using electronic cleaner or isopropylethanol.

If the key fob doesn't respond to cleaning, it is likely that the module is in an issue and must be replaced. A malfunctioning receiver could cause the key to stop working. This is often caused by electromagnetic interference.

Faulty electronic chip

The electronic chip in your key fob is a crucial element of the anti-theft device in your car. It sends a signal to the immobiliser in your car to inform it whether the key is genuine. The car will not start in the event that the chip is damaged.

A damaged chip could be caused by interference from objects, bad weather or transmitters in the vicinity of your vehicle. In this case the replacement fob will be needed.

Contacts to the battery are not working properly.

The battery contacts in the key fob are delicate and could be damaged through repeated use. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals that block out water. A splash of water or light rain should be fine however, submerging them in saltwater can cause damage to the electronic chip.

The key fob contains an embedded chip that communicates to the immobilizer system of the vehicle to start it. This system makes use of cryptocoding systems in modern vehicles as well as the traditional red key system used in older models. If the chip is defective and needs to be replaced.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob to function. When this happens the car's computer cannot recognize that the remote is within the vehicle.

Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.

To test the battery's power to determine its capacity, put an electric load on it for a couple of minutes. This will take away 1% of the surface charges. Then, you can measure the voltage. The better the battery's capacity, the longer it can keep its voltage. The ideal scenario is to keep it close to 12 volts for several minutes.

Problems with Radio Signal

This is the main reason for a keyfob that stops sending signals to the car. This issue can be fixed by replacing the battery. It is essential to purchase a battery with the same voltage and dimensions as the original.

The buttons are not impervious to destruction and can be damaged by a lot. The battery buttons and contacts are delicate and are susceptible to being bent or damaged by excessive use.

Other transmitters or objects operating on the same frequency could also disrupt a signal. A light-control system in your home, for instance could interfere with key fobs that use the same bandwidth. This could affect the remote control of your car.

Faulty OBDII scan tool

There are many reasons why scanners may not perform. Some are more complicated than others.

Professional scan tools permit mechanics to look over the car's networks and conduct a variety self-tests. These can be real time savers but they are also extremely expensive, and beyond the reach of most DIYers.

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK it's likely that a fuse has blown. This is the most typical reason for a scan tool to fail. The easiest solution is to replace the blown fuse.
