Fiat Panda Key Fob Replacement

fiat 500 key replacement uk Panda key fobs contain a transponder chip which sends signals to your car to open the doors or start the engine. The fob may stop working for a variety of reasons.

The most frequent cause of key fob malfunction is the battery of the coin is dead. Other causes include water damage a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery if the key fob has gone out of service. Use a new button cell battery with the same voltage, size and specification as the original.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned prior to being used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will be the solution.

If the key fob has not been exposed to water, but it is still not working it could be because of an issue with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner can assist.

Water Damage

If your key fob's battery has taken a bath in the pool or puddle, or taken a trip down the washing machine, you might have some water damage. You can usually get it back to working by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the board completely dry before installing the battery.

If your key fob has stopped working even after replacing the battery and reconfiguring it, you may have a faulty receiver module. There are instructions for changing the programming of most remote keys on YouTube or in your owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. If the chip is damaged, it will no longer send and receive signals to the vehicle. This could be due to dropping the key fob, or by exposure to water. If the key fob stops working after water exposure it is possible to repair it by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob does not respond after cleaning it, there is a good chance that the module is faulty and must be replaced. A damaged receiver can cause the key to cease to function. This is usually caused by electromagnetic interference.

Faulty electronic chip

The electronic chip that is in your key fob plays a vital role in the anti-theft security system of your car. It transmits a signal to the immobiliser unit in your vehicle to tell it whether or not the key is in fact valid. Your 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 instance you'll require a new key fob.

Contacts for the battery that are defective

The battery contacts on the key fob could be damaged due to heavy use. If they're damaged or bent, the key fob won't send any signals to the receiver modules in the car.

Modern fobs come with rubber seals in order to keep out water. In the event of submerging them in water, even if it's only an occasional drizzle or splash could harm the electronic chip.

The fiat key fob programming fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. This system utilizes cryptocoding systems in newer vehicles or the red key system for older models. The chip must be replaced if damaged.

Problematic 12 Volt Battery

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

Before replacing the battery, test it with an voltmeter for determining its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly, it's time to replace it.

To test the battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away 1percent of the surface charges. Then, test the voltage once more. The higher the capacity of the battery, the longer it can keep its voltage. The ideal scenario is to keep it close to 12 volts for several minutes.

Faulty Radio Signal

This is the most frequent reason behind a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. It is however important to select a replacement battery that has the same size and voltage as the original one.

Fobs are subject to a lot of abuse, but they're not impervious to destruction. The battery buttons and contacts are brittle and are susceptible to being bent or broken with rough use.

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

Afflicted OBDII scan tool

There are many reasons a scanner tool may not work. Some are more complicated than others.

Professional scan tools permit mechanics to observe the car's networks and perform a variety of self-tests. These can be real time savers, however they can be expensive, out of the range of most DIYers.

If your OBD2 scan tool isn't turning on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the chances are that a fuse has blown. This is among the most common causes of failures in the scan tool. The easiest fix is to replace the blown fuse.
