fiat Doblo key replacement Panda Key Fob Replacement

fiat 500x key fiat panda key fob keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car to unlock doors or turn on the motor. The fob could stop working for a variety of reasons.

The most common cause of key fob failure is an inoperable coin battery. Other causes are water damage or a malfunctioning module and interference signals.

Dead Coin Battery

If the battery in your key fob has gone out of service, the first step is to replace it. Choose a button battery with the same voltage, size, and specification as your old one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it needs to be cleaned before it can be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can be the solution.

If the key fob isn't working despite not being exposed to water it could be due to a malfunction in the receiver module or an internal electronic chip. In these instances it is possible that reprogramming the key fob with an OBDII scanner might assist.

Water Damage

If your key fob has taken an immersion in the puddle or pool or walked down the washing machine, you might have some water damage. It's possible to fix it by removing the batteries and cleaning the circuit board using rubbing alcohol. It's best to allow the device to completely dry before putting in batteries.

If your key fob has stopped working even after replacing the battery and programming it again, you might have a defective receiver module. You can find information on changing the programming of most remote keys on YouTube or consult your owner's manual. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. Dropping the fiat van key replacement fob could cause this, as could water exposure. If your key fob has stopped working due to exposure to water, you may be able to fix it if clean the chip with electronic cleaner or isopropylethanol.

If the key fob is still unable to not respond even after cleaning it it is likely that the component is damaged and must be replaced. A malfunctioning receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob is a vital part in the anti-theft security system of your car. It sends a signal to the immobiliser unit in your vehicle to tell it whether the key is valid. The car won't start when the chip is damaged.

A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency near your car. In this situation it is likely that a new fob would be required.

Contacts of the battery may be damaged.

The battery contacts in the key fob are delicate and can get damaged by repeated use. If they're bent or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs are constructed with rubber seals that keep out water. A splash of water or a light rain is fine However, submerging them in saltwater may harm the chip's electronic components.

The key fob has a chip which communicates with the immobilizer system of the vehicle to begin it. The system utilizes the red keys of older vehicles or the cryptocoding system that is used in modern vehicles. If the chip is not working properly, it will need to be replaced.

Problems with 12 Volt Batteries

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

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

Place an electrical load for a short time on the battery to determine its capacity. This will remove 1percent of the charges. Then, test the voltage again. The longer the battery can hold its voltage, the better its capacity. Ideal is to hold close to 12 volts for several minutes.

Faulty Radio Signal

This is the main reason for a keyfob that ceases to send signals to the car. The battery can be replaced to solve this issue. But, it is essential to purchase a battery that is the same voltage and size as the original.

Fobs can take a lot abuse, but they're also not indestructible. Contacts on batteries and buttons can be damaged through rough handling.

Other transmitters or objects that use the same frequency could also interfere with the signal. For instance, a lighting control panel that is near your home could transmit interference using the same frequency that key fobs utilize. This could affect the remote control of your car.

Afflicted OBDII scan tool

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

Professional scan tools let a mechanic observe the car's network, and run various self-tests. These tools can save time, but are expensive and out of reach for most DIYers.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition, a fuse may have blown. This is one of the most frequent causes of scan tool failure. The easiest solution is to replace the fuse that is blowing up.
