Dead Coin Battery

The most frequent reason for a key fob to not be able to lock or unlock your car is a dead coin battery. When it is dead, you will notice an increase in range or no power. It is simple to replace with a new one (CR2025) from a local supermarket. It is important to be aware that using the wrong or non-compatible batteries could damage your key fob. Make sure the replacement seat car key battery is the same size and voltage, and also the same specification.

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 due to corrosion. You might try cleaning your chip with alcohol or an electronic cleaner to see if it helps but it is more likely that the chip has been fried.

Water Damage

If your key fob gets wet from dropping it into the pool or by slipping it in the wash, you may think that it's lost but there's a chance. When the circuit board inside the fob is exposed to water, it becomes a conductor that 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 will be a good choice. Use a cotton swab with isopropyl to wash the circuit board and any other components. Allow the board to dry for several days in a dry, warm environment.

After the fob has dried out then replace the battery with an alternative of the same size and polarity ('+' that is pointing upwards). The fob might be difficult to open to get to the battery, but if you keep a flat-head screwdriver it should be easy to insert. Once the fob is reassembled and working, it should operate as normal. If it doesn't, you may require reprogramming it or replace the receiver module.

Radio Interference

If a keyfob functions correctly, it emits a radio frequency that is absorbed by a receiver module inside your vehicle. However, if the signal is distorted in some way your key fob will not work properly. This can be caused by objects such as weather conditions, objects, or other transmitters that operate at the same frequency close to your car.

Some LED lighting from the aftermarket that utilizes the same frequency as a remote key fob could interfere with the signal, preventing it from reaching the receiver modules. To prevent interference, the LED light must be turned off, or to another frequency.

If the issue continues to persist after replacing the battery, the antenna on the key fob might be damaged or inoperable. The antenna is responsible for transmitting a signal between the key fob and the receiver module. Using an OBDII scanner can help diagnose this issue by revealing what's wrong with the system. The scanner will ask to provide information about your vehicle, including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

The key fob comes with an electronic receiver that transmits signals for locking and unlocking. If this module is damaged then all the on-board electronics will cease to function. Reprogramming the key fob using an OBDII scan or replacing it can help.

This issue could be caused by a dead coin cell battery, water damage or signal interference. You can reset the on-board computer by disconnecting the 12 Volt batteries for 15 minutes. This will drain any residual electricity that could be causing problems. Begin by removing your cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order: positive first, negative second.

The internal chip in the key fob may be damaged by dirt or water. If your key has stopped working after getting wet, clean the electronic component using isopropyl alcohol or an electronic cleaner prior to installing the battery. If it stopped working after exposure to salty or soapy water the chip may be fried and will need to be replaced.

Another possibility is an inoperable antenna module fuse that sends the lock or unlock signal to the vehicle. The fuse can be found in a variety of locations, based on the type of vehicle. For instance it could be under the rear seat car key replacement or trunk, or on the side of the dashboard.
