Why You Should Focus On The Improvement Of Fiat 500 Keys Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car to unlock doors or start the motor. The fob could stop working due to a variety of reasons.

A dead coin battery is the most frequent reason for key fob malfunctions. Other causes include water damage, an inoperative receiver module and signal interference.

Dead Coin Battery

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

If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned prior to being used again. The best solution is to use a paper towel soaked with isopropyl, or electronic cleaner.

If the key fob is not working despite not being exposed to water it could be due a malfunction in the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob with an OBDII scanner can help.

Water Damage

If your key fob's battery has taken an immersion in the pool or puddle or gone to the washing machine, it could have some water damage. It is usually possible to get it working by taking the batteries off and cleaning the circuit board with rubbing alcohol. It is a good idea to allow the fob to dry completely before installing a new battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or updating. Reprogramming instructions are available for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This could be due to dropping the key fob or by water exposure. If the key fob stopped functioning after exposure to water, it may be possible to fix it by cleaning the chip with isopropyl alcohol or an electronic cleaner.


If the key fob is still unable to not respond after cleaning it there is a good chance that the component is damaged and will need to be replaced. A faulty receiver module can also cause the remote control key to stop working. This is often caused by electromagnetic interference.

A defective electronic chip

The electronic chip in your key fob plays a vital part in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car to determine that the key is valid. If the chip is damaged or broken, the car will not start.

A defective chip could be caused by interference from objects, bad weather or transmitters near your vehicle. In this situation you'll require a new key fob.

Faulty Battery Contacts

The battery contacts in a key fob are very delicate and may be damaged with hard usage. If they are broken or bent, the fob will not send any signals to the receiver modules in the car.

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

The key fob contains chip that communicates with the immobilizer system of the vehicle to begin it. It uses the old red keys that were used in older vehicles or the cryptocoding system that is used in the latest vehicles. The chip must be replaced if damaged.

Problematic 12 Volt Battery

A defective battery can cause the remote to cease to function. If this happens the car's computer will not be able to recognize that the remote is within the vehicle.

Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it is time to replace the battery.

To test a battery's capacity to determine its capacity, put an electric load on it for a few minutes. This will eliminate 1percent of the surface charges. Then, measure the voltage again. The longer the battery is able to hold its voltage greater is its capacity. The ideal is to keep it close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason for a key fob to stop sending signals to cars. This problem can be solved by replacing the battery. It is crucial to purchase an identical battery dimensions and voltage as the original.

Fobs can take a lot abuse, and they aren't impervious to destruction. Contacts and buttons on batteries can be damaged through rough handling.

A signal can also be affected by other transmitters or objects who use the same frequency. A light-control panel in your home, for instance can interfere with key fobs using the same frequency. This could interfere with the remote control of your car.

Incorrect OBDII scan tool

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

Professional scan tools let mechanics to look over the car's network and run various self-tests. These tools can save you a lot of time, but they're expensive and are out of reach for the majority of DIYers.

If your OBD2 scanner isn't turning on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If replacement fiat key fob 're all fine, a fuse may have blown. This is the main reason for failures of the scanner. The easiest solution is to replace the fuse which has blown.
