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

Dead Coin Battery

If your key fob's battery is dead, the first step is to replace it. Use a button cell that has the same voltage, size and specifications as the old one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned before being used again. The trick is to use an old towel soaked in isopropyl or electronic cleaner.

If the key fob is not working even though it is not exposed to water it could be due to a malfunction in the receiver module, or even in the internal electronic chip. In these instances you can reprogramme the key fob using an OBDII scanner may help.

Water Damage

If your key fob has taken submerged in a pool or puddle or walked down the wash machine, you could be suffering some water damage. It's generally possible to get it working by removing the batteries and cleaning the circuit board using rubbing alcohol. It is a good idea to let the fob dry completely before putting in a new battery.

It could be that you have a defective module in the event that your remote stops working after replacing the battery or updating. You can find information on the reprogramming of most remote keys on YouTube or consult the 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 which communicates with the vehicle's system. If the chip is damaged, it can no longer transmit or receive signals to the vehicle. This could be due to dropping the key fob or by exposure to water. If the key fob is not working after exposure to water, it is possible to repair it by cleaning the chip using isopropyl ethanol or electronic cleaner.

If the key fob is still unable to not respond following cleaning, then it is likely that the module is defective and must be replaced. A malfunctioning receiver module could also cause the remote control key to stop functioning. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip that is in your key fob plays a vital function in the anti-theft security system of your vehicle. It sends a signal the immobiliser unit in your car to determine whether the key is in fact valid. The car will not start in the event that the chip is damaged.

A defective chip could be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this situation it is likely that a new fob would be required.

Faulty battery contacts

The battery contacts on a key fob can be damaged due to heavy use. If they are damaged or bent, the key fob won't send any signals to the receiver modules inside the car.

Modern fobs have rubber seals to keep out water. Submerging them in water, even if it is just the slightest splash or drizzle could damage the chip's electronic circuit.

The key fob is equipped with a chip that communicates with the vehicle's immobilizer system in order to start it. The system utilizes the old red keys for older vehicles as well as the cryptocoding system that is used in the latest vehicles. The chip must be changed if it is faulty.

The 12 Volt Battery is faulty

A faulty battery may cause the key fob to function. If this happens the car's computer will not recognize that the remote is inside the vehicle.

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

Put an electrical load for a short time on the battery to check its capacity. This will remove 1percent of the surface charges. Then measure the voltage again. The better the battery's capacity is, the longer it will maintain its voltage. Ideally, it should remain close to 12 volts for several minutes.

Problems with Radio Signal

This is the most typical cause of a key fob that ceases to send signals to the car. The battery could be replaced to fix this problem. However, it is crucial to purchase a battery with the same voltage and size as the original one.

Fobs endure a lot of abuse, but they're also not impervious to destruction. Battery contacts and buttons can be damaged through rough handling.

Other transmitters or objects that use the same frequency can interfere with a signal. For instance, a light-control panel in your home could transmit interference using the same bandwidth that key fobs use. This could interfere with the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons why a scanner could not function. Certain are more complicated than others.

Professional scan tools let a mechanic observe the car's networks and run various self-tests. These tools can save time, but they are costly and out of reach for the majority of DIYers.

If your OBD2 scan tool doesn't turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine it could be that a fuse has failed. This is the most frequent reason for failures of the scanner. The simple fix is usually to replace the fuse which has blown.
