fiat key programmer fiat panda key Key Fob Replacement

fiat 500x key not detected Panda key fobs contain a transponder chip which sends a signal to your car to open the doors or start the engine. However, the fob could not function due to a variety of reasons.

A dead coin battery is the most frequent reason for the malfunction of a key fob. Other reasons include water damage, an inoperative receiver module, and signal interference.

Dead Coin Battery

If your key fob battery has failed, the initial step is to replace it. Use a button cell battery with the same voltage, size, and specifications as the old one.

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

If the key fob is not working despite not being exposed to water it could be due a malfunction in the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob using an OBDII scanner can help.

Water Damage

If your key fob took immersed in a puddle or pool, or taken a trip down the wash machine, it could have some water damage. You can usually 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 a good idea to let the fob dry completely before installing a new battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or changing the programming. Reprogramming instructions are available for most remote key fobs on YouTube or in your owner's guide. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. If the chip is damaged, it can no longer be able to send or receive signals to the vehicle. The key fob being dropped can cause this, as well as exposure to water. If your key fob stopped functioning due to water exposure it is possible to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob won't respond to cleaning, it's likely that the module is in an issue and must be replaced. A damaged receiver module may also cause the remote control key to stop working. This is usually caused by electromagnetic interference.

Electronic chip that is malfunctioning

The chip that is embedded in the key fob is a vital component of the anti-theft systems in your vehicle. It sends a message to the immobiliser in your car to inform it whether the fiat 500 key fob replacement is genuine. The car will not start in the event that the chip is damaged.

A damaged chip could be caused by interference signals from other objects like bad weather conditions or transmitters operating on the same frequency near your vehicle. In this situation the fiat punto replacement key fob will be required.

Contacts with the battery may be damaged.

The battery contacts on the fob's battery can be damaged by heavy usage. If they are broken or bent, the fob won't send any signals to the receiver modules in the car.

Modern fobs come with rubber seals to keep out water. A splash of water or light rain is acceptable but submerging them into salt water could damage the electronic chip.

The key fob has chip that communicates with the immobilizer system of the vehicle, allowing it to start it. This system utilizes cryptocoding systems in the latest vehicles as well as the traditional red key system in older ones. The chip must be changed if it is defective.

A faulty 12 Volt battery

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

Test the battery using the voltmeter before replacing it 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 capacity, place an electrical load on it for a few minutes. This will take away 1percent of the charges. Then, you can measure the voltage again. The higher the capacity of the battery, the longer it can keep its voltage. Ideal is that it stays close to 12 volts during several minutes.

Problems with Radio Signal

This is the main reason for fiat 500 all keys lost not sending signals to a car. The battery can be replaced to solve this problem. However, it is important to choose a battery that is the same voltage and size as the original.

Fobs are not indestructible and can be damaged by a lot. Contacts on batteries and buttons can be damaged by rough handling.

Other transmitters or objects using the same frequency can also interfere with the signal. For instance, a light-control panel near your home may send interference over the same frequency as key fobs use. This could affect the remote control in your car.

Faulty OBDII scan tool

There are a variety of reasons why scanners don't work. Some are more complex than others.

Professional scan tools enable mechanics to look over the car's network, and run various self-tests. These tools can save you a lot of time, but are costly and are out of reach for the majority of DIYers.

If your OBD2 scanner won't start make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse has been blown. This is the most frequent reason for a scan tool to fail. The easiest fix is to replace the fuse that is blowing up.
