Fiat Panda Key Fob Replacement

replacement fiat 500 key Panda key fobs contain transponder chips that send signals to your car to unlock the doors or start the engine. However, the fob could stop working due to a variety of causes.

The most common reason for key fob failure is a dead coin battery. Other causes are water damage, a faulty module, and interference signals.

Dead Coin Battery

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

If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned prior to using it again. A paper towel soaked in alcohol or electronic cleaner can help.

If the key fob hasn't been exposed to water, but remains inoperable it could be because of an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan could aid in these situations.

Water Damage

If your key fob's battery has taken immersed in a pool or puddle, or cost taken a trip down the wash machine, it could have some water damage. It is usually possible to get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the circuit board completely dry prior to installing batteries.

If your key fob stopped working, even after replacing the battery and reconfiguring it, you may have a faulty receiver module. There are reprogramming guidelines for most vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. If the chip is damaged, it can no longer transmit or receive signals to the vehicle. Dropping the key fob can cause this, as well as water exposure. If the key fob is not working after water exposure it may be possible to repair it by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob continues to not respond after cleaning it then it is likely that the component is damaged and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is often caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside your key fob is a crucial part of the anti-theft system in your car. It sends a message to the immobiliser in your car to determine if the key is valid. The car will not start if the chip is damaged.

A defective chip could be caused by interference caused by objects, bad weather or transmitters close to your vehicle. In this instance, you will need an entirely new key fob.

Contacts for the battery that are defective

The battery contacts of the key fob are delicate and can get damaged when used for long periods of time. If they're bent or broken, the fob won't send any signals to the receiver modules inside the vehicle.

Modern fobs feature rubber seals to keep out water. A splash of water or light rain should be fine However, submerging them in saltwater could damage the electronic chip.

The key fob houses chips that communicate with the vehicle's immobilizer in order to activate it. It uses the old red keys for older vehicles or the cryptocoding system found in the latest vehicles. This chip will need to be replaced if faulty.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob not to work. The car's computer may not recognize the remote if this occurs.

Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly, it's time to replace it.

Put an electrical load for a few seconds on the battery to determine its capacity. This will take away 1% of the surface charges. After that, measure the voltage. The better the battery's capacity and the longer it can keep its voltage. The ideal is to keep it close to 12 volts for several minutes.

This is the main reason for the key fob to stop sending signals to cars. The battery is able to be replaced to resolve this issue. It is crucial to purchase a battery that has the same voltage and dimensions as the original.

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

A signal can also be disrupted by other transmitters or objects who use the same frequency. For instance, a lighting control panel near your home may send interference over the same frequency as key fobs utilize. This could affect the remote control of your car.

Incorrect OBDII scan tool

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

Professional scan tools enable mechanics to look over the car's network and run various self-tests. These are great time savers, however they can be expensive, and beyond 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 they're all fine it could be that a fuse has ruptured. This is the most common reason for failures of the scanner. It is often easy to fix the issue by replacing the blown fuse.
