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 vehicle. It will usually show indications before it dies, such as a decreasing range or no power at any time. It is easy to replace it with a brand new (CR2025) one from your local store. You should be aware that using the wrong or unsuitable batteries could damage your key fob. Make sure that the new battery has the same size, specification 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 due to corrosion. You could try cleaning the chip using isopropyl alcohol or an electronic cleaner to see if it helps but it is most likely that the chip is damaged.
The simplest solution is to purchase a new key fob. Most major car dealers offer keys and can be installed by a skilled mechanic. You can also buy them online, such as on eBay. The best option is to work on a flat surface with excellent lighting. This will make it easier to work on the smaller parts inside. You'll also be able to avoid placing things in the wrong spot. Always keep the key fob in a secured and safe area.
Water Damage
You may think that your key fob is damaged if you drop it in a pool or accidentally wash it. There's a chance. If the circuit board inside the fob is exposed to water, it turns into conductor that shorts the components. It also speeds up corrosion and rust.
Fortunately, this is easy to fix. Simply locate something absorbent and place it inside the fob - a paper towl or tissue work well. Then you can use the cotton swab, dipped in isopropyl alcohol and wipe down the circuit board and other components to clean out any battery acid residue or contamination. Allow the circuit board to air dry in a dry, warm environment for a few weeks.
Replace the battery after the fob is dry by replacing it with a new one that is the same size and the same polarity ('+' (pointing upwards). The fob might be difficult to open to access the battery, but If you have a flat-head screwdriver it should be easy to slide in. After the fob has been reassembled, it should work as usual. If it doesn't, you might 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 picked up by the receiver module inside your car. If the signal is interrupted the key fob will not work. This could be caused by factors like weather conditions, objects, or other transmitters operating on the same frequency near your vehicle.
This can cause your key fob to not activate the vehicle's features for example, the ignition switch or the security system. It is best to replace your key fob's battery.
A few LED lighting aftermarkets that utilizes the same frequency 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 prevent interference.
If the problem persists after replacing the battery, the antenna of your key fob could be damaged or is malfunctioning. This is significant because the antenna is responsible for transmitting an indication from the key fob to the receiver module. The OBDII scanner is able to assist in diagnosing the problem by telling you what is wrong with the system. The scanner will ask you for details about your car including the make, model engine type, and VIN number.
Faulty Receiver Module
The
seat key fob comes with a receiver module that sends signals to lock and unlock the key fob. All on-board electronic components will cease to function if this module has a problem. Reprogramming the key fob with an OBDII scan, or replacing it may help.
This issue could be caused by a dead coin-cell 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 remove any remaining power that could cause issues. The cable should be removed first from the negative terminal, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First positive, then negative next.
The presence of dirt or water could harm the internal chip of the key fob. If your key has stopped working when it was wet, clean the electronic component using isopropyl alcohol or an electronic cleaner prior to reinstalling the battery. If it has stopped working after exposure to salty or soapy water, the chip is probably fried and will need to be replaced.
A damaged antenna module fuse may also be the cause. This is the fuse that transmits an electronic signal to the vehicle to lock or unlock. Depending on your model the fuse can be found in a variety of locations such as the engine bay, on the side of the dashboard, beneath the rear
