Dead Coin Battery
A dead coin battery is the most typical cause of a key fob that isn't locking or unlocking your vehicle. Before it dies, you will notice an increase in range, or no power. It is simple to replace it with a brand new (CR2025) one at your local grocery store. 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 battery you choose to replace is the same size and voltage and that it is the same specification.
If your device has been exposed to clean water, like rainwater or soapy water from the tap It is probable that corrosion has caused damage to the chip's electronic components. You can clean the chip using isopropyl or electronic cleaners to see if it can help, but the chip is damaged.
A new key fob is a simple solution. They are available from most major dealerships and can be installed by a qualified mechanic. They can also be purchased on ebay. The best thing to do is to work on a flat, level surface with good lighting. It is easier to work with small pieces. You will also be able to avoid putting things in the wrong spot.

Water Damage
If your key fob gets damaged by dropping it in the pool or slipping it in the wash, you may think that it's gone but there's still hope. The issue begins when the circuit board in the fob comes into contact with water. It is a great conductor and cuts off components. It also increases corrosion and rust.
This is a simple fix. Find something absorbent to place inside the fob. A tissue or paper towel will work well. Use a cotton swab that contains isopropyl for cleaning the circuit board as well as any other components. Let the fob air dry in a dry, warm environment for a few weeks.
Replace the battery when the fob is dry by replacing it with a new one with the same size and the same polarity ('+' (pointing upwards). It isn't easy to open up the fob to reach the battery, however if you have a small flat-head screwdriver at hand, it will slide in easily. Once the fob is reassembled and working, it should operate like normal. If it doesn't work it may be necessary to program it again or replace the module.
Radio Interference
When a keyfob operates correctly, it emits an audio frequency that is received by a receiver module inside your vehicle. If the signal is not received the key fob will not function. This can be caused by objects or weather conditions, or other transmitters operating at the same frequency close to your car.
In this case it is best to replace the battery in your key fob. In this situation it's best to replace the battery on your key fob.
Some aftermarket LED lighting that uses the same frequency as a remote key fob can interfere with the signal, preventing it from reaching the receiver modules. The LED's lighting needs to be turned off or switched to a different frequency in order to keep out interference.
If you have a brand new battery on your key fob but the issue persists, it's possible that the antenna on the key fob is damaged or inoperable. This is since the antenna is responsible for sending an indication from the key fob to the receiver module. An OBDII scan can help you identify the issue by telling you exactly what's wrong with the system. The scanner will ask you for details about your car, including the model, make engine type, VIN number.
Faulty Receiver Module
The key fob comes with a receiver module that transmits signals for locking and unlocking. All on-board electronic components will cease to function if this module is affected by a malfunction. If this happens it is possible to reprogramme the module using an OBDII scanner or replacing the key fob itself could aid.
There are a few possibilities for the cause of this problem that could be the cause, such as a dead coin battery, water damage, or signal interference. You can try resetting the computer on board by disconnecting the battery 12 volts for 15 minutes. This will drain any remaining power that could be causing problems. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First positive, then negative, and finally negative.
seat car key cover or dirt can also affect the internal chip inside the key fob. If the key fob you purchased stopped working after being wet, wash it with isopropyl or electronic cleaner. Then, you can reinstall the battery. If it has stopped working after exposure to soapy or salty water the chip may be damaged and must be replaced.
Another possibility is an inoperable antenna module fuse that transmits the signal to lock or unlock to the vehicle. The fuse may be located in a variety of locations, based on the model. For instance, it could be under the rear seat or trunk, or the side of the dashboard.
