fiat keys replacement Panda key fobs contain transponder chips that send signals to your car to open the doors and start the engine. The fob might stop working due to a variety of reasons.

A dead coin battery is the most common reason for a key fob malfunction. Other causes are water damage or a damaged module and interference signals.

Dead Coin Battery

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

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned before using again. A paper towel soaked in isopropyl alcohol or electronic cleaner can work wonders.

If the key fob hasn't been exposed to water but still does not work, there may be 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

There could be water damage to your key fob if it was submerged in a puddle, pool or washing machine. You can usually get it working again by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob completely dry prior to installing a battery.

You may have a faulty module if your key fob stops working after replacing the battery or changing the programming. There are instructions for changing the programming of most remote keys on YouTube or in your owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that connects to the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This can be caused by dropping the key fob, or due to exposure to water. If the key fob has stopped working after water exposure it is possible to fix it by cleaning the chip with isopropyl ethanol or electronic cleaner.

If the key fob doesn't respond to cleaning, it's likely that the module is in issues and needs to be replaced. A malfunctioning receiver could cause the key to stop working. This is typically caused by electromagnetic interference.

Faulty electronic chip

The electronic chip in your key fob is an important component of the anti-theft systems in your vehicle. It sends out a signal the immobiliser device in your car to determine whether the key is valid. If the chip is damaged or broken, the car will not start.

A faulty chip may also be caused by interference from objects, bad weather or transmitters close to your vehicle. In this situation you'll require a new key fob.

Contacts for the battery that are damaged

The battery contacts inside a key fob are very delicate and could be damaged when used for long periods of time. If they're damaged or bent, the fob will not transmit any signals to the receiver modules in the car.

Modern fobs feature rubber seals that block out water. Submerging them in water, even if it is just a light drizzle or splash could harm the chip's electronic circuit.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to start it. The system is based on the old red keys in older vehicles, or the cryptocoding system used in newer vehicles. If the chip is defective, it will need to be replaced.

Faulty 12 Volt Battery

A malfunctioning battery could cause the remote to cease working. When this happens, the car's computer system cannot recognize that the remote is in the vehicle.

Before you replace the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly the time is now to replace it.

Place an electrical load for a short time on the battery to test its capacity. This will eliminate approximately 1% of the charge on the surface. After that, measure the voltage. The better the battery's capacity and the longer it can keep its voltage. Ideally, it will remain close to 12 volts several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for a key fob to stop sending signals to cars. The battery can be replaced to solve this issue. It is however important to choose a battery that has the same size and voltage as the original one.

Fobs are subject to a lot of abuse, but they're not indestructible. The battery buttons and contacts are brittle which means they could be bent or damaged from rough usage.

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

Incorrect OBDII scan tool

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

Professional scan tools allow a mechanic to examine the car's systems and perform a variety of self-tests. They can be huge time savers but they are also extremely expensive, and beyond the reach of most DIYers.

If your OBD2 scan tool doesn't turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, it's likely that a fuse is blowing. This is the most common cause of scan tool failure. It is usually simple to fix the issue by replacing the blown fuse.
