Dead Coin Battery

A dead battery for a coin is the most typical cause of a seat arona key fob not locking or unlocking your vehicle. When it is dead, you will see a decrease in range or no power. It is easy to replace with a brand new one (CR2025) from a local store. Be aware that faulty or defective batteries could damage the key fob. Make sure that the replacement battery is the same size and voltage and has the same specifications.

If your fob was exposed to clean water, such as 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 with isopropyl Alcohol or an electronic cleaner to test if it helps, but it is most likely that the chip is damaged.

The most efficient solution is to get an entirely new key fob. The majority of major car dealers sell keys and can be installed by a skilled mechanic. They can also be purchased online from places like ebay. The best option is to work on a flat, level surface with adequate lighting. This makes it easier to work on the tiny parts inside. You will also be able to avoid placing something in the wrong place. Always work on your key fob in a location that is safe and secure.

Water Damage

If your key fob is soaked by dropping it in the pool or by slipping it in the wash you might think that it's gone but there's still hope. When the circuit board in the fob is exposed to water, it develops a conductor that shorts out the components. It also speeds up corrosion and rust.

This is an easy fix. Simply find something absorbent and place it inside the fob - paper towl or tissue can be used. Then apply an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board and other components to remove any residue of battery acid and contamination. Allow the board to dry for several days in a dry and warm environment.

After the fob has dried out, replace the battery with a new one of the same size and the same polarity ('+' with the upwards direction). It can be tricky to open the fob to access the battery, but if you have a small screwdriver that is flat available, it should be able to slide into easily. After the fob is reassembled and working, it should operate as usual. If it fails, you may have to program it again or replace the module.

Radio Interference

If a keyfob functions properly, it transmits a radio frequency that is picked up by a receiver module in your vehicle. If the signal is interrupted, your key fob will not function. This can be caused by objects such as weather conditions, objects, or other transmitters that operate at the same frequency close to your car.

This can cause your key fob's button to not work the vehicle's features like the ignition switch or the security system. It is best to replace the battery of your key fob.

A few LED lighting products that utilizes the same frequency as the remote control key fob could 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 you have a brand new battery on your key fob but the problem persists, it's likely that the antenna on your key fob is damaged or malfunctioning. This is since the antenna is responsible for transmitting an indication from the key fob to the receiver module. An OBDII scanner can help diagnose this issue by telling you what is wrong with the system. The scanner will ask you for details about your car, including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

The key fob has a receiver module that transmits the signals to lock and unlock. All electronic components that are on-board will cease to function if this module becomes inoperable. Reprogramming the key fob with an OBDII scan, or replacing it may help.

There are a few possible reasons for this problem, including an empty coin battery, water damage, or signal interference. You can reset the onboard computer if you disconnect the 12 volt batteries for 15 minutes. This will drain any remaining electricity that could be causing problems. Begin by removing your cable from the negative terminal first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order first, positive second.

The presence of dirt or water could damage the internal chip of the key fob. If the key fob you purchased stopped working after getting wet, wipe it with isopropyl, or an electronics cleaner. Then, you can reinstall the battery. If the key stopped working after being exposed to salted or soapy water, it's likely that the chip has been damaged and needs to be replaced.

Another possibility is an inoperable antenna module fuse that sends the signal to lock or unlock to the vehicle. Depending on the model the fuse can be located in a variety of locations such as the engine bay, on the side of the dashboard, beneath the rear seat car keyless entry, or in the trunk.
