A dead battery for the coin is the most frequent cause of the malfunction of a key fob. Other causes are water damage, a faulty receiver module and signal interference.

Dead Coin Battery

If the battery in your key fob has gone out of service, the first thing to do is replace it. Use a button cell battery with 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 being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can help.

If the key fob hasn't been exposed to water, but still does not work, there may be a problem with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner might help.

Water Damage

If your key fob has taken a bath in the pool or puddle or walked down the wash machine, it could have some water damage. It is usually possible to restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the fob completely dry before installing the battery.

It could be that you have a defective module in the event that your key fob stops working after replacing the battery or changing the programming. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the car's system. If the chip is damaged, it will be unable to longer transmit and receive signals to the vehicle. Dropping the key fob can cause this, as well as water exposure. If your key fob stopped functioning due to exposure to water it is possible fix the issue if you clean the chip using electronic cleaner or isopropyl ethanol.

However, if the key fob still does not respond after cleaning it it is likely that the module is faulty and must be replaced. A damaged receiver module may also cause the remote control key to cease functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an important component of the anti-theft system in your car. It transmits a signal to the immobiliser device in your car to determine whether or not the key is valid. If the chip is damaged or damaged, your car won't start.

A faulty chip can also be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency close to your vehicle. In this situation an upgrade to the fob will be needed.

Faulty battery contacts

The battery contacts on a key fob can be damaged through heavy use. If they are damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs feature rubber seals that keep out water. A splash of water or a light rain should be fine, but submerging them in saltwater may harm the electronic chip.

The key fob has an electronic chip that communicates with the vehicle's immobilizer to allow it to start it. This system makes use of cryptocoding systems in modern vehicles as well as the traditional red key system used in older models. If the chip is damaged, it will need to be replaced.

The 12 Volt Battery is faulty

A damaged battery can cause the remote to cease to function. When this happens the car's computer cannot recognize that the remote is within the vehicle.

Before you replace the battery, test it by using a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly it is time to replace the battery.

To test the battery's power to determine its capacity, put an electric load on it for a couple of minutes. This will eliminate about 1 percent of the charge on the surface. Then take another measurement of the voltage. The higher the capacity of the battery and the longer it can maintain its voltage. The ideal scenario is to keep it close to 12 volts for several minutes.

Faulty Radio Signal

This is the most frequent cause of a key fob that stops sending signals to the car. The battery can be replaced to solve this issue. It is however important to buy a fiat 500 new key cost uk battery that is the same size and voltage as the original.

Fobs endure a lot of punishment, and aren't impervious to destruction. The battery contacts and buttons are delicate and are susceptible to being bent or broken with rough usage.

Other objects or transmitters using the same frequency can also interfere with the signal. For example, a light-control panel close to your home can send interference over the same bandwidth that key fobs use. This could affect the remote control of your car.

Faulty OBDII scan tool

There are many reasons why scanners may not function. Certain are more complicated than others.

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

If your OBD2 scanner won't turn on Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape it's possible that a fuse has blown. This is the most typical reason for failures of the scanner. The simple fix is usually to replace the fuse that is blowing up.
