fiat key Panda Key Fob fiat replacement car keys

fiat ducato key Panda keyfobs are equipped with a transponder, which sends a signal from the fob to the car in order to unlock doors or start the motor. The fob may stop working due to a variety reasons.

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

Dead Coin Battery

Replace the battery if the key fob has failed. Use a button cell that has the same voltage, size and specification as your old one.

If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned before being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner can work wonders.

If the key fob hasn't been exposed to water, but it is still not working, there may be an issue with the receiver module or an internal electronic chip. In these situations you can reprogramme the key fob using an OBDII scanner may help.

Water Damage

You might have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's generally possible to get it back in working order by taking the batteries off and cleaning the circuit board with ruby alcohol. It's best to allow the device to completely dry before putting in a battery.

If your fiat punto evo key fob isn't working, even after replacing the battery and reconfiguring it, you may have a defective receiver module. You can find the instructions for reprogramming most vehicles' remote keys on YouTube or in your owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob has an electronic chip that communicates with the car's system. The chip will stop sending and receiving signals to the car when it is damaged. This can be caused by dropping the key fob, or by exposure to water. If the key fob has stopped working after water exposure it is possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.

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

A malfunctioning electronic chip

The electronic chip inside the fiat punto key fob is a crucial component of the anti-theft system in your car. It sends a signal the immobiliser unit inside your car to inform it whether the key is genuine. The car will not start in the event that the chip has been damaged.

A defective chip could be caused by interference from objects, bad weather or transmitters close to your vehicle. In this case, you will need a new key fob.

Contacts for the battery that are defective

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

Modern fobs are equipped with rubber seals that keep out water. A splash of water or a light rain is fine however, submerging them in saltwater could damage the chip's electronic components.

The key fob has an electronic chip that communicates with the immobilizer system of the vehicle to start it. This system utilizes cryptocoding systems in the latest vehicles and the older red key system for older ones. If this chip is faulty it will have to be replaced.

Poor 12 Volt Battery

A defective battery can cause the key fob not to work. When this happens, the car's computer system won't recognize that the remote is in the vehicle.

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

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

Problems with Radio Signal

This is the most typical reason for the key fob not sending signals to cars. The battery could be replaced to fix this problem. It is crucial to buy an identical battery voltage and dimensions as the original.

Fobs aren't impervious to damage and can withstand a lot. The battery buttons and contacts are delicate and can be bent or broken with rough use.

A signal may also be impacted by other objects or transmitters that use the same frequency. A light-control panel at your home, for example, may interfere with key fobs using the same bandwidth. This can interfere with the remote control of your car.

The tool is not working properly. OBDII scan tool

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

Professional scan tools allow a mechanic to observe the car's networks and run a range of self-tests. These can be real time savers but they are also extremely expensive, and out of the reach of most DIYers.

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK, a fuse may have failed. This is the main cause of scan tool failure. The easiest solution is to replace the fuse that has been blown.
