Dead Coin Battery

A dead battery on a coin is the most common reason of a key fob that isn't locking or unlocking your car. After it has died you will see a decrease in range or no power. It is easy to replace with a brand new one (CR2025) from an area supermarket. You should be aware that using the wrong or non-compatible batteries can damage your key fob. Make sure the battery you replace has the same size and voltage, as well as the same specifications.

If your fob was exposed to clean water, like rain or soapy tap water it is possible that the electronic chip inside has been damaged due to corrosion. You may try cleaning the chip using isopropyl alcohol or an electronic cleaner to see if it helps but it is more likely that the chip has been damaged and fried.

The most efficient option is to buy an entirely new key fob. Most major car dealers offer key fobs and they can be installed by a seasoned mechanic. They can also be purchased on the internet from sites like ebay. It is best to work on a surface that has adequate lighting. It is much easier to work on the small parts. This also helps you to avoid putting something back in the wrong place. Always keep the key fob in a secured and safe location.

Water Damage

If your fob's key gets submerged after dropping it into the pool or slipping it in the wash, you may think it's a goner but there's a chance. The issue begins when the circuit board inside the fob is in contact with water - it creates a fantastic conductor, and it shorts out the components. It also increases corrosion and rust.

This is a simple solution. Find something absorbent to place inside the fob. A paper towel or tissue will work well. Then make use of a cotton swab dipped in isopropyl alcohol to clean the circuit board and other components to clean out any residue of battery acid and contamination. Allow the circuit board to air dry in a dry, warm environment for several weeks.

When the fob has dried out then replace the battery with a new one (of the same size and the same polarity ('+' directed upwards). It can be difficult to open the fob in order to access the battery but if you have a small flat-head screwdriver that you have at hand, it will be able to insert easily. After the fob is repaired, it should function like a normal. If it doesn't, then you'll require reprogramming it or replace the receiver module.

Radio Interference

If a key fob is functioning properly, it emits the radio frequency signal which is interpreted by the receiver module in your car. If the signal is not received, your key fob won't work. This could be due to objects like weather conditions or other transmitters that operate on the same frequency in close proximity to your vehicle.

This could cause your key fob to not be able to activate the vehicle's functions like the ignition switch or the security system. In this case it's best to replace the battery on your key fob.

A few LED lights that are aftermarket and uses the same frequency as the remote key fob may interfere with the signal, preventing it from reaching the receiver modules. To prevent G28 , the LED light must be turned off, or to another frequency.

If you have a brand new battery on your key fob but the problem persists, it's likely that the antenna on the key fob is damaged or inoperable. This is crucial because the antenna is responsible for transmitting signals from the key fob to the receiver module. A scan of the OBDII can help you identify the issue by revealing what's wrong with the system. The scanner will ask for details about your vehicle, including the model, make, engine type and VIN number.

Faulty Receiver Module

The key fob comes with a receiver module that sends signals to lock and unlock the key fob. If this module develops a fault and the on-board electronics will cease to function. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob may assist.

There are several possible reasons for this problem such as a dead coin battery water damage, or signal interference. Try resetting the computer on board by disconnecting the battery 12 volts for 15 minutes. This will flush out any residual electricity that could be causing issues. Begin by removing your cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order: positive first, negative second.

Dirt and water can damage the internal chip of the key fob. If your key stopped working when it was wet, wash the electronic component using isopropyl alcohol or an electronic cleaner prior to installing the battery. If it stopped working after exposure to salty or soapy water the chip may be damaged and must be replaced.

Another possibility is a damaged antenna module fuse that transmits the lock and unlock signal to the vehicle. The fuse can be located in a variety of locations, based on the type of vehicle. For example it could be under the rear seat, or in the trunk, or the side of the dashboard.
