Why You Should Focus On Enhancing Fiat 500 Keys
Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that sends an indication from the fob to the car to unlock doors or turn on the motor. However, the fob can stop working due to a variety of causes.

A dead coin battery is the most common reason for malfunctioning keys. Other causes include water damage the receiver module is defective, and signal interference.

Dead Coin Battery

If your key fob battery has gone out of service, the first thing to do is replace it. Use a new button cell battery that has the same size, voltage and specification as the old one.

If the key fob was exposed to water, such as a splash of rain or salt water on the beach, it will need to be cleaned before it is able to be used again. A paper towel soaked in alcohol or electronic cleaner can do the trick.

If the key fob has not been exposed to water, but it is still not working it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob through an OBDII scan may assist in these situations.

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's possible to get it working by taking out the batteries and cleaning the circuit board with rubbing alcohol. It's a good idea let the fob dry completely before putting in a brand new battery.

If your key fob isn't working even after replacing the battery and changing the program, you could have a defective receiver module. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in the owner's manual. 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. If the chip is damaged, it can no longer transmit and receive signals to the vehicle. Dropping the key fob could cause this, as well as water exposure. If the key fob stopped working after exposure to water it is possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.

However, if the key fob is still unable to not respond after cleaning it, it is likely that the component is damaged and must be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is an important element of the anti-theft device in your car. It transmits a message the immobiliser inside your car to determine whether the key is legitimate. If the chip is damaged or broken, your car will not start.

A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters operating on the same frequency near your car. In this instance you'll need a new key fob.

Contacts with the battery may be damaged.


The battery contacts inside a key fob are very delicate and can get damaged by repeated use. If they are bent or broken the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs feature rubber seals that keep out water. Submerging them in water, even if it's only the slightest splash or drizzle could harm the electronic chip.

The key fob is equipped with chip that communicates with the immobilizer system of the vehicle to start it. The system relies on cryptocoding systems in vehicles that are more modern as well as the traditional red key system used in older ones. If this chip is faulty it will have to be replaced.

Problematic 12 Volt Battery

A damaged battery could cause the key fob to work. When this happens, the car's computer system will not be able to recognize that the remote is inside the vehicle.

Before you replace the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly the time is now to replace it.

Install an electrical charge for a few seconds on the battery to check its capacity. This will take off about 1 percent of the surface charge. Then, you can measure the voltage again. The greater the battery's capacity is, the longer it will maintain its voltage. Ideal is to hold close to 12 volts over several minutes.

fiat ducato key replacement is the main reason for a key fob that ceases to send signals to the car. The battery can be replaced to fix this issue. It is important to buy batteries that have the same dimensions and voltage as the original.

Fobs aren't impervious to damage and can be damaged by a lot. Contacts and buttons on batteries can be damaged by rough handling.

Other transmitters or objects operating on the same frequency can disrupt the signal. A light control panel in your home, for example could interfere with key fobs that use the same frequency. This can affect the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons why a scan tool could not work. Certain are more complicated than others.

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

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's possible that a fuse has blown. This is the main reason for failure of the scan tool. The simple fix is usually to replace the fuse that has been blown.
