Dead Coin Battery

Replace the battery in case your key fob has gone out of service. Use a new button cell battery with the same size, voltage, and specification as the old one.

If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. The best solution is to use a paper towel that has been soaked in isopropyl, or electronic cleaner.

If the key fob is not working despite not being exposed water, it could be due to a glitch in the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner could aid.

Water Damage

If your key fob took an immersion in the puddle or pool or gone through the washing machine, you may have some water damage. It is usually possible to be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's a good idea allow the fob to dry completely before putting in a brand new battery.

There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in the owner's guide. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob can cause this, as well as water exposure. If your fiat punto key replacement fob has stopped functioning due to water exposure it is possible fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.

If the fiat 500 replacement key cost fob won't respond to cleaning, it's possible that the module has an issue and should be replaced. A malfunctioning receiver could cause the key to stop working. This is usually due to electromagnetic interference.

A defective electronic chip

The chip inside your key fob plays a vital role in the anti-theft security system of your vehicle. It sends a message to the immobiliser in your car to inform it whether the key is legitimate. If the chip is damaged or broken, your car will not start.

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

Contacts to the battery are not working properly.

The battery contacts of the key fob could be damaged due to heavy use. If they're bent, or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs are made with rubber seals that keep out water. Submerging them in water even if it's just small splash or drizzle can harm the chip's electronic circuit.

The key fob is equipped with chip that communicates with the immobilizer system of the vehicle to begin it. The system utilizes the old red keys that were used in older vehicles as well as the cryptocoding system used in newer cars. The chip must be changed if it is faulty.

The 12 Volt Battery is faulty

A faulty battery can cause the remote to stop working. The car's computer may not recognize the remote when this occurs.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly then it's time to replace it.

Set an electrical load for a short time on the battery to check its capacity. This will remove one percent of the surface charges. After that, take the voltage again. The longer a battery can keep its voltage steady and the higher its capacity. Ideally, it should remain close to 12 volts several minutes.

Faulty Radio Signal

This is the most common reason for the key fob not sending signals to vehicles. The battery could be replaced to fix this issue. It is crucial to buy batteries that have the same voltage and dimensions as the original.

Fobs take a lot of abuse, but they're not indestructible. The battery contacts and buttons could be damaged through rough handling.

A signal can also be disrupted by other objects or transmitters who use the same frequency. For example, a light-control panel near your home may transmit interference on the same frequency that key fobs utilize. This could interfere with your car's remote control.

Faulty OBDII scan tool

There are many reasons a scanner tool may not function. Some are more complicated than others.

Professional scan tools let mechanics to look over the car's network, and run various self-tests. These are great time savers but they're also expensive, and out of the range of most DIYers.

If your OBD2 scanner won't start examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK it's likely that a fuse is blowing. This is one of the most common reasons for failure of the scanner. It is usually simple to fix the issue by replacing the fuse that has blown.
