Dead Coin Battery

The most frequent reason for a key fob that does not lock or unlock your car is a dead coin battery. If it fails, you will notice a decrease in range or no power. It is simple to replace it with a brand new (CR2025) one from a local retailer. Be aware that using the wrong or non-compatible batteries could damage your key fob. Make sure that the new battery has the same size, specification and voltage as the old one.

If your device has been exposed to clean water, such as rainwater or soapy water from the tap It is probable that corrosion has caused damage to the electronic chip. You can try cleaning the chip using isopropyl alcohol or an electronic cleaner to see if it helps but it is likely that the chip has been damaged and fried.

The most efficient option is to buy a new key fob. The majority of major car dealers sell them and they can be installed by a seasoned mechanic. You can also buy them online, such as on eBay. It is recommended to work on a surface that is equipped with adequate lighting. It is much easier to work on small parts. It also allows you to avoid placing things in the wrong spot. Always keep your key fob in a place that is secure and safe.

Water Damage

You may think your seat key fob fob is destroyed if drop it into the water or accidentally wash it. However, there's still a chance. The issue begins when the circuit board in the fob comes into contact with water. It creates a fantastic conductor and cuts off components. It also speeds up the process of rust and corrosion.

This is an easy solution. Simply find something absorbent and place it inside the fob. A paper towl or tissue work well. Use a cotton swab with isopropyl to clean the circuit board and any other components. Let the fob air dry in a warm, dry environment for a few weeks.

After the fob has been drained and the battery is replaced with a new one (of the same size and the same polarity ('+' directed upwards). The fob may be difficult opening to access the battery, however when you have a flat head screwdriver it should be easy to insert. Once the fob is reassembled, it should work like normal. If it doesn't, you might require reprogramming it or replace the receiver module.

Radio Interference

When a keyfob is working correctly, it emits the radio frequency which is absorbed by a receiver module in your car. However, if the signal is distorted in any way the key fob won't function properly. This may be due to objects, weather conditions or other transmitters operating within the same frequency band near your car.

This could cause your key fob's button to not work the vehicle's systems such as the ignition switch or the security system. It is recommended to replace your key fob's battery.

Some LED lighting from the aftermarket that utilizes the same frequency as a remote key fob can interfere with the signal and prevent it from reaching the receiver modules. The LED's light source must be switched off or changed to a different frequency to keep out interference.

If you have a new battery in your key fob, and the issue persists, it is likely that the antenna of your key fob is damaged or has stopped working. This is because the antenna is responsible for transmitting a signal from the key fob to the receiver module. An OBDII scan will help you identify the issue by revealing exactly what's wrong with your system. The scanner will ask for information about your specific vehicle including the model and make of the vehicle, the type of engine, and VIN number.

Faulty Receiver Module

The key fob houses an encoder module that transmits the signals for locking and unlock. All electronic components on board will cease to function if this module develops a problem. Reprogramming the key fob using an OBDII scan, or replacing it may help.

This problem can be caused by a dead coin-cell either from water damage or signal interference. Try resetting the on-board computer by disconnecting the 12 volt battery for 15 minutes. This will flush out any residual electric current that could cause issues. Start by removing the cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.

The internal chip inside the key fob can be damaged by dirt or water. If your key quit working after it got wet, wash the electronic component using isopropyl alcohol or an electronic cleaner prior to installing the battery. If the key stops working after exposure to salted or soapy water, it's likely that the chip has been damaged and must be replaced.

A damaged antenna module fuse could also be the cause. It is the fuse that sends an alert to the vehicle to lock or unlock. The fuse may be located in a variety of locations, based on the model. For instance, it could be under the rear seat key or trunk, or the side of the dashboard.
