fiat key Panda key fobs contain a transponder chip which sends signals to your car to open the doors or start the engine. However, the key fob may not function due to a variety of reasons.

The most common cause of key fob failure is an inoperable coin battery. Other causes include water damage as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery in case your key fob has failed. Use a brand new button battery with the same voltage, size and specification like the previous one.

If the key fob was exposed to water, such as a splash of rain or salt water at the beach, it will need to be cleaned before it can be used again. The trick is to use a paper towel that has been soaked in isopropyl or electronic cleaner.

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

Water Damage

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

You may have a faulty module when your key fob ceases working after replacing the battery or reprogramming. You can find information on changing the programming of most remote keys on YouTube or in your owner's manual. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob could cause this, as could water exposure. If your key fob stopped functioning due to water exposure it is possible to fix it if clean the chip with electronic cleaner or isopropyl alcohol.

However, if the key fob continues to not respond after cleaning it there is a good chance that the component is damaged and must be replaced. A defective receiver module could also cause the remote control key to cease functioning. This is often caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob plays a crucial function in the anti-theft security system of your vehicle. It sends a signal to the immobiliser inside your car that tells it that the key is valid. If the chip is damaged or broken, your vehicle will not start.

A malfunctioning chip can be caused by interference from other objects, bad weather or transmitters in the vicinity of your vehicle. In this instance you'll need a new key fob.

Contacts to the battery are not working properly.

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

Modern fobs are constructed with rubber seals in order to keep out water. A splash of water or a light rain is acceptable, but submerging them in saltwater could damage the electronic chip.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. This system uses crypto coding systems in the latest vehicles, or the old red key system used in older ones. If the chip is defective, it will need to be replaced.

Problematic 12 Volt Battery

A defective battery can cause the remote to cease to function. When this occurs the car's computer won't recognize that the remote is inside the vehicle.

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

To test the battery's capacity, place an electrical load on it for a few minutes. This will eliminate 1% of the surface charges. Then take another measurement of the voltage. The longer the battery is able to keep its voltage steady and the higher its capacity. Ideally, it should remain close to 12 volts several minutes.

Problems with Radio Signal

This is the most common reason for a keyfob that stops sending signals to the car. The issue can be fixed by replacing the battery. It is crucial to purchase a battery that has the same dimensions and voltage as the original.

The buttons are not impervious to destruction and can withstand a lot. The battery buttons and contacts are delicate and can be bent or broken with the force of.

A signal may also be impacted by other objects or transmitters that operate on the same frequency. A light-control panel in your home, for example could interfere with key fobs using the same bandwidth. This could interfere with your car's remote control.

Problems with OBDII Scan Tool

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

Professional scan tools permit mechanics to observe the car's networks and perform a variety of self-tests. These tools can save time, but are costly and out of reach for the majority of DIYers.

If your OBD2 scan tool fails to turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it could be that a fuse has blown. This is one of the most frequent reasons for failure of the scanner. It is often easy to fix the issue by replacing the fuse that has blown.
