Dead Coin Battery

A dead coin battery is the most frequent cause of a key fob that isn't locking or unlocking your car. It usually shows warning signs prior to dying like a lower range or no power at any time. It is easy to replace with a brand new one (CR2025) from the local supermarket. Be aware that using the wrong or non-compatible batteries can cause damage to your key fob. Make sure that the new battery has the same size, specification and voltage as the old one.

If your fob was exposed to clean water, like rainwater or soapy tap water it is possible that corrosion has caused damage to the chip's electronic circuit. You could try cleaning the chip with isopropyl Alcohol or an electronic cleaner to try to see if this helps but it is likely that the chip has fried.

The most efficient solution is to get a new key fob. Major car dealers sell them and they can be installed by a skilled mechanic. You can also buy them online, for example on eBay. The best way to work is to work on a flat surface that has good lighting. It is much easier to work on the smaller parts. You will also be able to avoid placing things in the wrong place. Always keep the key fob in a secured and safe area.

Water Damage

You may think your key fob is destroyed if drop it into an unintentional pool or accidentally wash it. But there's still hope. The problem starts when the circuit board within the fob comes in contact with water - it creates an excellent conductor, and it shorts out the components. It also speeds up corrosion and rust.

Fortunately, this is not difficult to fix. Find something absorbent to place inside the fob. A paper towel or tissue will work well. Then you can use an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board as well as other components to eliminate any residue of battery acid and contamination. The fob should dry for a few days in a dry, warm environment.

Replace the battery after the fob has dried out by a new one that is the same dimensions and polarity ('+' (pointing upwards). It can be tricky to open up the fob to reach the battery but if you have a small screwdriver with a flat head available, it should be able to slide into easily. After the fob is reassembled, it should work as normal. If it does not work, you may have to program it again or replace the module.

Radio Interference

If a key fob is functioning properly, it emits a radio frequency signal that is received by the receiver module in your car. If the signal is not received the key fob will not work. This could be due to objects, weather conditions or other transmitters operating within the same frequency band near your vehicle.

In this scenario it is recommended to replace the battery in your key fob. In this instance, it would be best to replace the battery in your key fob.

A few LED lighting aftermarkets that utilizes the same frequencies as a remote control key fob may interfere with the signal, preventing it from reaching receiver modules. The LED's light source must be turned off or switched to a different frequency in order to be able to avoid interference.

If the issue persists after installing a new battery, the antenna of your key fob could be damaged or not functioning properly. This is because the antenna is responsible for transmitting a signal from the key fob to the receiver module. An OBDII scan can assist in diagnosing the issue by telling you exactly what's wrong with your system. The scanner will request details about your vehicle, such as the make and model along with the engine type and VIN number.

Faulty Receiver Module

The key fob is equipped with an electronic receiver that transmits signals for locking and unlocking. If this module fails then all the on-board electronics will stop working. Reprogramming the key fob by an OBDII scan, or replacing it can help.

There are a variety of possible causes for this issue that could be the cause, such as the battery of the coin is dead, water damage or signal interference. You can reset the on-board computer by disconnecting the 12 Volt batteries for 15 minutes. This will flush out any residual electric current that could cause issues. The cable should be removed first from the negative terminal, then from the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First, positive and then negative the next.

The internal chip of the key fob can be damaged by water or dirt. If your key stopped working after getting wet, wash the electronic component with isopropyl Alcohol or an electronics cleaner before reinstalling the battery. If the key ceases to function after being exposed to salted or soapy water, it is likely that the chip has been fried and needs to be replaced.

Another possibility is a damaged antenna module fuse, which transmits the lock or unlock signal to the vehicle. The fuse could be found in several places, depending on the model. For instance it could be under the rear seat car keys, or in the trunk, or the side of the dashboard.
