Beware Of This Common Mistake With Your Fiat 500 Keys

Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder which transmits a signal from the fob to the car in order to unlock doors or turn on the motor. The fob can stop functioning due to a variety of reasons.

A dead coin battery is the most common reason for the malfunction of a key fob. Other causes include water damage, the receiver module is defective and signal interference.

Dead Coin Battery

Replace the battery if the key fob is dead. Use a new button cell battery that has the same size, voltage and specifications like the previous one.

If the key 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 can be used again. The best method is to use an old towel soaked in isopropyl or electronic cleaner.

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

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It is usually possible to restore it's functionality by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to allow the device to completely dry prior to installing a battery.

You could have a damaged module in the event that your key fob stops working after replacing the battery or changing the programming. There are reprogramming guidelines for most remote key fobs on YouTube or in the owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob has the chip that communicates 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 by water exposure. If the key fob stopped working after water exposure it may be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob does not respond to cleaning, it is likely that the module is in issues and needs to be replaced. A damaged receiver module may also cause the remote control key to cease functioning. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an important part of the anti-theft system in your car. It transmits a message to the immobiliser in your car to determine whether the key is genuine. If the chip is damaged or broken, the car won't start.

A malfunctioning chip could be caused by interference signals from other objects or weather conditions that are bad, or transmitters operating on the same frequency close to your vehicle. In this scenario, you will need a new key fob.

Faulty Battery Contacts

The battery contacts on a key fob are very delicate and may be damaged through repeated use. If they're broken or bent, the fob will not transmit any signals to the receiver modules inside the car.

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

The key fob has an embedded chip that communicates to the immobilizer system of the vehicle to begin it. This system uses crypto coding systems in vehicles that are more modern or the red key system for older ones. If the chip is not working properly it will have to be replaced.

Problematic 12 Volt Battery

A damaged battery could cause the key fob to function. The car's computer will not recognize the remote when this happens.

Before fiat ducato key replace the battery, test it using a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly, it's time to replace it.

Place an electrical load for a short period of time on the battery to gauge its capacity. This will take off approximately 1% of the surface charge. Then take another measurement of the voltage. The longer the battery can hold its voltage and the higher its capacity. Ideal is that it stays close to 12 volts over several minutes.

Problems with Radio Signal

This is the most typical reason for a keyfob that stops sending signals to the car. The battery can be replaced to fix this problem. It is essential to purchase batteries that have the same dimensions and voltage as the original.

Fobs take a lot of punishment, and aren't indestructible. The battery contacts and buttons are delicate which means they could be bent or broken with the force of.

The signal could also be disrupted by other objects or transmitters which use the same frequency. For example, a light-control panel that is near your home could transmit interference using the same bandwidth that key fobs utilize. This can interfere with the remote control in your car.

Problems with OBDII Scan Tool

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

Professional scan tools enable mechanics to examine the car's systems and run a variety of self-tests. These can be real time savers, but they can be expensive, and out of the budget of most DIYers.

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine the fuse could have blown. This is among the most common causes of scan tool failure. The simple fix is usually to replace the fuse that is blowing up.
