Dead Coin Battery

The most common reason for a key fob that does not lock or unlock your vehicle is a dead coin battery. If it fails, you will see a decrease in range or no power. It is simple to replace it with a new one (CR2025) from a local store. It is important to be aware that using the wrong or incompatible batteries could damage your key fob. Make sure the battery you choose to replace is the same size and voltage as well as the same specifications.

If your fob was exposed to pure water, such as rainwater or soapy tap water, it is likely that corrosion has damaged the chip's electronic components. You could try cleaning the chip with alcohol or an electronic cleaner to test if it helps, but it is likely the chip has been damaged and fried.

The simplest solution is to get an entirely new key fob. They are available at most major car dealers and can be fitted by an experienced mechanic. You can also buy them online, such as on eBay. The best option is to work on a level surface with good lighting. This makes it easier to work on small parts inside. You will also be able to avoid putting things in the wrong place. Always work on the key fob in a secured and safe place.

Water Damage

If your key fob gets soaked by dropping it in the pool or throwing it in the wash, you may think that it's gone but there's a chance. When the circuit board on the fob is exposed to water, it turns into conductor that shorts the components. It also speeds up corrosion and rust.

This is a simple fix. Find something absorbent to put inside the fob. A tissue or paper towel would be ideal. Use a cotton swab with isopropyl to cleanse the circuit board, and any other components. Let the circuit board dry for a few days in a warm and dry environment.

Once the fob is dried out it is time to replace the battery another one of the same size and the same polarity ('+' pointing upwards). It isn't easy to open the fob to reach the battery, but if have a small screwdriver with a flat head at hand, it will slide in easily. After the fob is put back together, it should work just as normal. If it doesn't work, you'll require reprogramming it or replace the receiver module.

Radio Interference

If a key fob is functioning correctly, it transmits the radio frequency signal which is picked up by the receiver module in your car. If the signal is disrupted the key fob won't work. This may be due to objects, weather conditions or other transmitters operating within the same frequency band close to your car.

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

Some LED lighting aftermarket that utilizes the same frequencies as key fobs for remote control may interfere with the signal, stopping it from reaching receiver modules. The LED lighting must be turned off or switched to a different frequency in order to avoid interference.

If the issue persists after installing a new battery, the antenna on your key fob could be damaged or inoperable. The antenna is responsible to transmit a signal between the key fob and the receiver module. A scan of the OBDII can help you identify the issue by telling you exactly what's wrong with the system. The scanner will ask for details about your vehicle, such as the model and make along with the engine type and VIN number.

Faulty Receiver Module

The key fob has an electronic receiver that transmits signals for locking and unlocking. All electronic components that are on-board will cease functioning if this component has a problem. Reprogramming the key fob with an OBDII scan, or replacing it may help.

There are a few possible causes that could be the cause, such as a dead coin battery, water damage, or signal interference. You can try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will remove any remaining electrical energy that could be causing problems. Begin by removing your cable from the negative terminal first, followed by the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. Positive first, then negative, and finally negative.

The presence of dirt or water could damage the internal chip of the key fob. If the key fob you purchased stopped working after being soaked, clean it with isopropyl or electronics cleaner. Then, you can reinstall the battery. If it stops working after exposure to salty or soapy water, the chip is probably damaged and must be replaced.

A faulty antenna module fuse could also be the cause. It is the fuse that transmits an electronic signal to the vehicle to lock or unlock. Depending on the model the fuse could be located in one of several locations like the engine bay, on the side of the dashboard, under the rear seat, or trunk.
