fiat bravo key Panda Key Fob Replacement

Fiat Punto Remote Key Panda key fobs contain a transponder chip which sends signals to your car to open the doors or start the engine. However, the key fob may be inoperable due to various reasons.

A dead coin battery is the most common cause of the malfunction of a key fob. Other causes include water damage malfunctioning receiver modules and signal interference.

Dead Coin Battery

Replace the battery if the key fob has died. Choose a new button battery that is exactly the same size, voltage and specification as the old one.

If the fiat key cover fob was exposed to water, like a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. The best solution is to use the paper towel and soak it in isopropyl or electronic cleaner.

If the key fob doesn't working despite being not exposed to water, it could be due to a problem in the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan may assist in these situations.

Water Damage

You might have water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to allow the device to completely dry prior to installing batteries.

If your key fob has stopped working, even after replacing the battery and reconfiguring it, you may have a malfunctioning receiver module. Reprogramming instructions are available for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. This can be caused by dropping the key fob, or through exposure to water. If your key fob isn't working due to exposure to water and you are unable to fix it if clean the chip with electronic cleaner or isopropylethanol.

If the key fob won't respond to cleaning, it's possible that the receiver module has a fault and needs to be replaced. A defective receiver can cause the key to cease to function. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob plays a crucial part in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car to tell it whether the key is genuine. If the chip is damaged or broken, your car won't start.

A malfunctioning chip can be caused by interference from other objects, bad weather or transmitters in the vicinity of your vehicle. In this situation an upgrade to the fob will be needed.

Contacts to the battery are not working properly.

The battery contacts on the key fob are delicate and can get damaged when used for long periods of time. If they are broken or bent, the fob will not transmit any signals to the receiver modules in the car.

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

The key fob is equipped with chips that communicate with the vehicle's immobilizer to allow it to activate it. This system makes use of cryptocoding systems in the latest vehicles, or the old red key system used in older models. If the chip is not working properly it must be replaced.

A faulty 12 Volt battery

A faulty battery may cause the key fob to work. When this occurs, the car's computer system cannot recognize that the remote is within the vehicle.

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly, it's time to replace it.

Place an electrical load for a short period of time on the battery to check its capacity. This will eliminate approximately 1% of the surface charge. Then, measure the voltage again. The better the battery's capacity is, the longer it will keep its voltage. The ideal is to keep it at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most frequent reason for a fiat 500 spare key cost uk fob to stop sending signals to the car. The battery could be replaced to fix this problem. However, it is important to select a replacement battery that has the same size and voltage as the original one.

The buttons are not impervious to destruction and can take a lot. The battery contacts and buttons are delicate, so they can get bent or damaged by excessive use.

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

Incorrect OBDII scan tool

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

Professional scan tools enable mechanics to observe the car's network and perform various self-tests. These can be real time savers, but they can be expensive and are out of the reach 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, it's likely that a fuse has blown. This is one of the most frequent causes of a scan tool failing. The easiest fix is to replace the fuse that is blowing up.
