fiat punto remote key replacement Panda Key Fob fiat 500 replacement remote key cost

fiat 500 key fob Panda key fobs contain a transponder chip that sends an alert to your car to open the doors and start the engine. The fob can stop functioning for a variety of reasons.

The most common reason for key fob failure is a dead coin battery. Other reasons include water damage, a faulty receiver module, and signal interference.

Dead Coin Battery

If your key fob battery has died, the first step is to replace it. Make use of a new fiat 500 key button battery that is exactly the same size, voltage, and specification like the previous one.

If the key fob was exposed to water, such as a splash of rain or salt water at the beach, it will need to be cleaned before it can be used again. A paper towel soaked in alcohol or electronic cleaner can do the trick.

If the key fob doesn't working despite not being exposed water it could be due a malfunction in the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner can help.

Water Damage

If your key fob's battery has taken submerged in a puddle or pool or walked down the wash machine, you may have some water damage. It's possible to get it back in working order by removing the batteries and cleaning the circuit board using rubbing alcohol. It is a good idea to let the fob dry completely before putting in a brand new battery.

If your key fob stopped working, even after replacing the battery and changing the program, you could have a faulty receiver module. You can find instructions for reprograming the majority of remote keys on YouTube or refer to the owner's manual. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip that connects to the vehicle's system. The chip will stop sending and receiving signals to the car when it is damaged. The key fob being dropped can cause this, as can water exposure. If your key fob isn't working due to water exposure, you may be able to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob is still unable to not respond following cleaning, there is a good chance that the module is defective and needs to be replaced. A damaged receiver can cause the key to not work. This usually happens due to electromagnetic interference.

A defective electronic chip

The electronic chip inside your key fob is an essential element of the anti-theft device in your vehicle. It sends out a signal the immobiliser unit in the vehicle to determine whether the key is in fact valid. The car won't start in the event that the chip is damaged.

A malfunctioning chip can be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this case an upgrade to the fob will be required.

Contacts for the battery that are damaged

The battery contacts on a key fob can be damaged through heavy use. If they're bent or broken the fob will not be able to send any signals to the receiver modules in the car.

Modern fobs feature rubber seals that block out water. Submerging them in water even if it's just a light drizzle or splash can harm the chip's electronic components.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle, allowing it to start it. It uses the red keys of older vehicles as well as the cryptocoding system that is used in newer vehicles. This chip will have to be replaced if defective.

Faulty 12 Volt Batterie

A faulty battery can cause the remote to cease working. When this happens, the car's computer system won't recognize that the remote is inside the vehicle.

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

To test a battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away about 1% of the surface charge. Then, measure the voltage again. The longer a battery can hold its voltage greater is its capacity. Ideally, it should remain close to 12 volts for several minutes.

Problems with Radio Signal

This is the most common reason for keys not sending signals to vehicles. The battery could be replaced to fix this problem. It is however important to select a replacement fiat panda key battery with the same voltage and size as the original one.

Fobs endure a lot of abuse, and they aren't indestructible. The battery buttons and the contacts are fragile and can be bent or broken with rough usage.

Other transmitters or objects using the same frequency can also interfere with the signal. For instance, a light-control panel close to your home can send interference on the same frequency that key fobs use. This could interfere with your car's remote control.

Faulty OBDII scan tool

There are many reasons why a scanner may not work. Some are more complex than others.

Professional scan tools let a mechanic observe the car's network and perform various self-tests. These are real time savers, but they can also be very expensive, and out of the range of most DIYers.

If your OBD2 scanner won't start Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's possible that a fuse has been blown. This is the most typical reason for failures of the scanner. It is typically easy to fix the issue by replacing the fuse that has blown.
