Fiat Panda Key Fob Replacement

fiat 500 spare key Panda key fobs contain a transponder chip that sends a signal to your car to open the doors and start the engine. However, the key fob may 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 causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Make use of a new button battery that is exactly the same size, voltage, and specification like the previous one.

If the key fob has been exposed to water, like a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked in alcohol or electronic cleaner can be the solution.

If the key fob isn't working despite not being exposed water it could be due to a malfunction in the receiver module or in the internal electronic chip. Reprogramming the keyfob through an OBDII scan can assist in these situations.

Water Damage

It is possible to get water damage if your key fob was submerged in a pool, puddle or washing machine. It's possible to fix it by taking the batteries off and cleaning the circuit board using rubbing alcohol. It's best to let the circuit board completely dry before putting in batteries.

If your key fob isn't working, even after replacing the battery and changing the program, you could have a problem with the receiver module. You can find information on reprograming the majority of remote keys on YouTube or in your owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with 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 could be due to dropping the key fob or due to exposure to water. If the key fob is not working after exposure to water, it could be possible to repair it by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob does not respond to cleaning, it is possible that the component has a fault and needs to be replaced. A defective receiver module could also cause the remote control key to not function. This is usually caused by electromagnetic interference.

A defective electronic chip

The electronic chip inside your key fob is a vital part in the anti-theft security system of your vehicle. It transmits a message the immobiliser in your car to tell it whether the key is genuine. If the chip is damaged or damaged, your car won't start.

A damaged chip could be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency near your car. In this situation, you will need a new key fob.

Contacts to the battery are not working properly.

The battery contacts of a key fob can be damaged due to heavy use. If they're bent, or damaged, the fob will not send any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals to keep out water. A splash of water or light rain should be fine However, submerging them in salt water could cause damage to the chip's electronic components.

The key fob contains a chip that communicates with the vehicle's immobilizer in order to allow it to start. This system utilizes cryptocoding systems in the latest vehicles and the older red key system for older ones. If the chip is not working properly and needs to be replaced.

Faulty 12 Volt Batterie

A malfunctioning battery could cause the remote to cease working. If this happens, the car's computer system will not be able to recognize that the remote is inside the vehicle.

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly the time is now to replace it.

To test a battery's capacity to determine its capacity, put an electric load on it for a couple of minutes. This will remove 1percent of the charges. Then, you can measure the voltage again. The higher the capacity of the battery, the longer it can maintain its voltage. It is ideal to maintain at or near 12 volts for several minutes.

Problems with Radio Signal

This is the most common reason for the key fob not sending signals to vehicles. The battery could be replaced to fix this problem. It is however important to choose a battery that has the same size and voltage as the original.

The buttons are not impervious to destruction and can take a lot. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with excessive use.

Other transmitters or objects using the same frequency can also disrupt a signal. A light-control panel in your home, for example, may interfere with key fobs that use the same frequency. This can interfere with your car's remote control.

Incorrect OBDII Scan Tool

There are a number of reasons why a scanner could not work. Some are more complicated than others.

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

If your OBD2 scan tool isn't turning on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition there is a chance that a fuse has failed. This is one of the most frequent reasons for failure of the scanner. It is generally simple to fix the issue by replacing the fuse that has blown.
