Dead Coin Battery

The most common reason for a key fob to not allow you to lock or unlock your car is due to a dead coin battery. After it has died you will see an increase in range, or no power. It is simple to replace it with a new (CR2025) one from a local retailer. Be aware that defective or defective batteries could damage the key fob. Make sure that the battery you purchase is identical in size, specifications and voltage as your old one.

If your fob was exposed to clean water, like rain or soapy tap water it is possible that the chip inside has been damaged by corrosion. You can clean the chip using isopropyl or electronic cleaners to see if it can help, but the chip is damaged.

A new key fob is the most straightforward solution. The majority of major car dealers sell keys and can be installed by a skilled mechanic. You can also purchase them online, like on eBay. The best option is to work on a level surface with adequate lighting. This makes it easier to work on the tiny parts inside. It also allows you to avoid putting things in the wrong spot. Always keep your key fob in an area that is secure and safe.

Water Damage

If your key fob gets wet from dropping it into the pool or by slipping it in the wash, you may think that it's lost but there's still hope. When the circuit board on the fob is exposed to water, it transforms into conductor that shorts the components. It also accelerates the process of rust and corrosion.

Luckily, this is a simple issue to fix. Find something absorbent to put inside the fob. A tissue or paper towel would work. Then you can use a cotton swab that has been soaked in isopropyl alcohol to wipe down the circuit board and other components to clean out any residues of acid from batteries and contamination. Allow the circuit board to air dry in a dry, warm environment for a few weeks.

Replace the battery after the fob has dried out by replacing it with a new one that is the same size and polarity ('+' (pointing upwards). The fob might be difficult to open in order to access the battery, however when you have a flat head screwdriver at hand it will be a breeze to insert. After the fob is reassembled it should function like a normal. If it doesn't work, you'll need to reprogram it or replace the receiver module.

Radio Interference

If a keyfob functions properly, it transmits the radio frequency which is received by a receiver module inside your car. If the signal is disrupted in any way your key fob will not perform as it should. This could be due to factors like weather conditions, objects, or other transmitters operating in the same frequency range near your vehicle.

This can cause your key fob to not activate the vehicle's features, such as the ignition switch or security system. It is recommended to replace the battery on your key fob.

Some LED lighting aftermarket that uses the same frequencies as key fobs for remote control could interfere with the signal, stopping it from reaching receiver modules. To avoid interference, the LED lights should be turned off or to the opposite frequency.

If the issue continues to persist after replacing the battery, the antenna on your key fob may be damaged or malfunctioning. The antenna is responsible for transmitting a signal between the key fob and the receiver module. An OBDII scanner can aid in identifying the issue by telling you what is wrong with the system. The scanner will ask you for details about your vehicle, including the make, model, engine type and VIN number.

Faulty Receiver Module

The key fob houses an electronic receiver that sends the signals for lock and unlock. If the receiver module is damaged that causes it to fail, the entire onboard electronic components will stop functioning. If this happens, reprogramming with an OBDII scanner or replacing the key fob itself could help.

There are a few possibilities for the cause of this problem that could be the cause, such as a dead coin battery, water damage, or signal interference. You can reset the on-board computer if you disconnect the 12 volt batteries for 15 minutes. This will flush out any residual electric current that could cause issues. Begin by removing the cable from the negative terminal first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order first, positive second.

The presence of dirt or water could cause damage to the internal chip of the key fob. If your key fob stopped functioning after getting wet, wipe it with isopropyl or electronic cleaner. Then, reinstall the battery. If it stops working after exposure to soapy or salty water the chip could be damaged and should be replaced.

A faulty antenna module fuse could also be the reason. It's the fuse that transmits an alert to the vehicle to lock or unlock. Based on the model you have the fuse could be located in a variety of locations, such as the engine bay, the side of the dashboard, beneath the rear seat, or trunk.
