Dead Coin Battery

A dead battery for a coin is the most common cause of a key fob that isn't locking or unlocking your vehicle. It is likely to show indications before it dies, such as a decreased range or no power at all. It is easy to replace it with a new one (CR2025) from an area supermarket. You should be aware that using the wrong or non-compatible batteries could damage your key fob. Make sure that the new battery is identical in size, specifications and voltage as the older one.

If your device was exposed to clean water, such as rain or soapy tap water it is likely that the chip inside has been damaged by corrosion. You can clean the chip using isopropyl or electronic cleaners to determine if that aids, but that the chip has been damaged.

A new key fob is the most straightforward solution. They are readily available from major seat car key cover dealers and are installed by a qualified mechanic. They can also be purchased on the internet through sites like ebay. It is recommended to work on a work surface that has adequate lighting. It makes it easier to work with small parts.

Water Damage

You may think that your key fob is lost if you drop it into an unintentional pool or accidentally wash it. But there's still hope. When the circuit board on the fob is exposed to water, it develops a conductor which shorts the components. It also speeds up the process of corrosion and rust.

Fortunately, this is not difficult to fix. Find something absorbent, and place it inside the fob - a paper towl or tissue is ideal. Use a cotton swab that contains isopropyl to wash the circuit board as well as any other components. Let the circuit board dry for a few days in a warm and dry environment.

After the fob has dried out then replace the battery with a new one (of the same size and the same polarity ('+' that is pointing upwards). The fob may be difficult to open to get to the battery, but when you have a flat head screwdriver, it should be easy to slide in. After the fob is repaired, it should function just as normal. If it doesn't work, you'll need to reprogram it or replace the receiver module.

Radio Interference

If a key-fob is working correctly, it sends a radio frequency signal that is picked up by the receiver module inside your car. If the signal is disrupted the key fob will not work. This could be caused by weather conditiominal of the battery first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order first, positive second.

The internal chip inside the key fob may be damaged by dirt or water. If your key fob stops working after being wet, wash it with isopropyl or electronic cleaner. Then, you can reinstall the battery. If your key seat has stopped working after being exposed to salted or soapy water, it's likely that the chip has been damaged and must be replaced.

A defective fuse for the antenna module could be a cause. This is the fuse that sends an alert to the vehicle to lock or unlock. The fuse can be found in a variety of places, based on the model. For example it could be under the rear seat arona key, or in the trunk, or on the side of the dashboard.
