Dead Coin Battery

A dead battery on a coin is the most typical cause of a key fob not locking or unlocking your car. It usually shows signs before it dies such as a decreased range or no power at any time. It is simple to replace with a new one (CR2025) from an area supermarket. Be aware that using the wrong or unsuitable batteries could cause damage to 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, such as rain or soapy tap water, it is likely that the electronic chip inside has been damaged due to corrosion. You can clean the chip with isopropyl or electronic cleaners to see if it can help, but that the chip has been damaged.

Water Damage

You may think your key fob is damaged if you drop it into an unintentional pool or accidentally wash it. But there's a way to salvage it. When the circuit board in the fob is exposed to water, it develops an electrical conductor, which shorts the components. It also speeds up corrosion and rust.

Fortunately, this is easy to fix. Find something absorbent to place inside the fob. A tissue or a paper towel will work. Use a cotton swab soaked in isopropyl for cleaning the circuit board as well as any other components. The fob should dry for a few days in a dry and warm environment.

When the fob has been drained, replace the battery with another one of the same size and the same polarity ('+' directed upwards). It isn't easy to open the fob to access the battery but if you have a small screwdriver with a flat head handy it should slide in easily.

Radio Interference

If a keyfob works properly, it broadcasts a radio signal that is received by a module inside your car. However, if the signal is disrupted in some way the key fob will not perform as it should. This could be due to objects or weather conditions, or other transmitters that operate at the same frequency close to your car.

This can cause your key fob to not be able to activate the vehicle's systems like the ignition switch or the security system. In this instance, it would be best to replace the battery in your key fob.

A few LED lighting products that utilizes the same frequency as a key fob for remote control may interfere with the signal, stopping it from reaching receiver modules. To avoid interference, the LED light must be turned off, or switched to a different frequency.

If you have a brand new battery in your key fob and the issue persists, it is possible that the key fob's antenna is damaged or malfunctioning. This is crucial since the antenna is responsible for sending signals from the key fob to the receiver module. A scan of the OBDII can help you identify the issue by revealing exactly what's wrong with your system. The scanner will ask you for details about your vehicle, including the make, model engine type, VIN number.

Faulty Receiver Module

The key fob has an encoder module that transmits the signals for locking and unlock. If this module is damaged that causes it to fail, the entire onboard electronics will stop working. Reprogramming the key fob by an OBDII scan, or replacing it may help.

This problem could be caused by a dead battery in the coin-cell either from water damage or signal interference. Try resetting the computer on board 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 of the battery first, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First, positive, then negative, and finally negative.

Dirt and water can cause damage to the internal chip of the key fob. If your key fob stops working after getting wet, wipe it with isopropyl or electronic cleaner. Then, reinstall the battery. If it has stopped working after exposure to soapy or salty water the chip may be fried and will need to be replaced.

A damaged antenna module fuse could also be the cause. It is the fuse that sends an electronic signal to the vehicle to lock or unlock. Depending on the model the fuse can be located in one of the many locations including the engine bay, the side of the dashboard, beneath the rear seat ibiza replacement key cost ibiza key fob not working (look at here), or in the trunk.
