Dead Coin Battery

The most frequent reason for a key fob to not lock or unlock your car is a dead coin battery. Before it dies you'll notice an increase in range, or no power. It is easy to replace it with a new (CR2025) one from a local retailer. It is important to be aware that using the wrong or non-compatible batteries can cause damage to your key fob. Make sure that the new battery has 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 possible that the chip inside has been damaged by corrosion. You can clean the chip with isopropyl or electronic cleaners to see if this can help, but that the chip has been damaged.

The simplest option is to buy an entirely new key fob. Most major car dealers sell them and they can be installed by a seasoned mechanic. You can also buy them online, such as on eBay. The best option is to work on a flat surface that has excellent lighting. It is easier to work with small parts. You'll also be able to avoid placing something in the wrong place. Always work on your key fob in a place that is safe and secure.

Water Damage

You might think that your key fob is lost if you drop it in an unintentional pool or accidentally wash it. But there's a way to salvage it. The problem begins when the circuit board inside the fob comes in contact with water. It creates a fantastic conductor, and it shorts out the components. It also accelerates the process of corrosion and rust.

Luckily, this is simple to fix. Find something absorbent to place inside the fob. A tissue or paper towel would be ideal. Then apply an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board and other components to get rid of any battery acid residue and contamination. Let the fob air dry in a dry, warm environment for several weeks.

Replace the battery when the fob has dried out with a fresh one that is the same size and polarity ('+' (pointing upwards). It isn't easy to open up the fob to get access to the battery, but if you have a small flat-head screwdriver at hand, it will slide in easily. After the fob has been reassembled it should function as usual. If it doesn't, you may need to reprogram it or replace the receiver module.

Radio Interference

When a keyfob is working properly, it broadcasts the radio frequency which is picked up by a receiver module in your car. If the signal is disrupted in any way the key fob will not work properly. This could be due to objects or weather conditions, or other transmitters that operate at the same frequency as your car.

This can cause your key fob not to be able to trigger the vehicle's functions for example, the ignition switch or security system. It is recommended to replace the battery of your key fob.

Some aftermarket LED lighting 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 light must be turned off or switched to a different frequency in order to be able to avoid interference.

If you've just replaced the battery in your key fob, and the issue persists, it's possible that the antenna of your key fob is damaged or inoperable. This is since the antenna is responsible for sending a signal from the key fob to the receiver module. An OBDII scan will assist in diagnosing the issue by revealing exactly what's wrong with your system. The scanner will request details about the vehicle you own including the model and make, engine type, and VIN number.

Faulty Receiver Module

The key fob contains the receiver module which transmits the signals for lock and unlock. All on-board electronic components will stop working if this module has a problem. Reprogramming the key fob using an OBDII scan or replacing it could help.

There are a few possibilities for the cause of this problem which could be due to an empty coin battery, water damage, or signal interference. You can reset your on-board computer if you disconnect the 12 Volt batteries for 15 minutes. This will remove any remaining electricity that could be causing issues. Begin by removing the cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order first: positive, then negative second.

The internal chip inside the key fob could be damaged by water or dirt. If your key has stopped working after it got wet, clean the electronic component with isopropyl alcohol or an electronic cleaner prior to reinstalling the battery. If it stops working after exposure to salty or soapy water, the chip is probably damaged and should be replaced.

Another possibility is a defective antenna module fuse that sends the lock or unlock signal to the vehicle. Depending on your model, the fuse is located in one of the many locations like the engine bay, side of the dashboard, beneath the rear seat replacement car key seat exeo key programming Key Programming (Sweeney-Nixon-3.Technetbloggers.De), or trunk.
