Dead Coin Battery
A dead battery on a coin is the most typical cause of a key fob that isn’t locking or unlocking your car. After it has died, you will notice an increase in range or no power. It is simple to replace it with a new (CR2025) one from your local store. You should be aware that using the wrong or unsuitable batteries could damage your key fob. Make sure that the new battery is identical in size, specifications and voltage as your old one.
If your fob was exposed to clean water like rain or soapy tap water, it is possible that the electronic chip inside has been damaged by corrosion. You can try cleaning the chip using isopropyl alcohol or an electronic cleaner to check if it works but it is likely that the chip has been damaged and fried.
The simplest solution is to get an entirely new key fob. They are available at most major car dealers and can be fitted by an experienced mechanic. You can also purchase them online, such as on eBay. It is recommended to work on a surface that is equipped with adequate lighting. This will make it easier to work on the small parts inside. This can also help to avoid placing anything back in the wrong location. Always work on your key fob in an area that is secure and safe.
Water Damage
You may think your key fob is ruined if you drop it into a pool or accidentally wash it. But there’s a way to salvage it. When the circuit board on the fob is exposed to water, it turns into a conductor which shorts the components. It also accelerates corrosion and rust.
This is a simple solution. Find something absorbent to put inside the fob. A tissue or a paper towel will work. Use a cotton swab with isopropyl for cleaning the circuit board as well as any other components. The fob should dry for some time in a warm and dry environment.
Replace the battery once the fob has dried by replacing it with a new one that is the same dimensions and the same polarity (‘+’ (pointing upwards). It can be difficult to open the fob in order to access the battery, however if you have a small screwdriver that is flat that you have at hand, it will be able to insert easily. Once the fob is reassembled, it should work as normal. If it doesn’t, you may require reprogramming it or replace the receiver module.
Radio Interference
When a keyfob is working properly, it transmits a radio signal that is absorbed by a receiver module inside your car seat key. If the signal is interrupted, your key fob will not function. This may be due to weather conditions, objects or other transmitters operating on the same frequency band close to your vehicle.
In this situation it is recommended to replace the battery on your key fob. It is best to replace the battery in your key fob.
Some aftermarket LED lighting that utilizes the same frequency as the remote key fob may 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 the issue is still present after replacing the battery, the antenna on your key fob could be damaged or not functioning properly. The antenna is responsible for transmitting signals between the key fob and the receiver module. Using an OBDII scanner can aid in diagnosing the issue by revealing what’s wrong with the system. The scanner will ask for details about your particular vehicle including the make and model as well as the engine type and VIN number.
Faulty Receiver Module
The key fob is equipped with a receiver module that sends signals for locking and unlocking. All on-board electronic components will stop working if the receiver module becomes inoperable. Reprogramming the key fob using an OBDII scan or replacing it could help.
There are a few possible causes such as a dead 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 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, connect the battery in reverse order beginning with positive first, and negative second.
Dirt and water can harm the internal chip of the key fob. If your key quit working after being wet, you need to clean the electronic component with isopropyl alcohol or an electronic cleaner prior to installing the battery. If it is not working after exposure to soapy or salty water the chip may be fried and will need to be replaced.
A faulty antenna module fuse may also be the cause. It is the fuse that transmits an indication to the vehicle to lock or unlock. The fuse can be found in various places, based on the type of vehicle. For instance it could be under the rear seat, or in the trunk, or on the side of the dashboard.
