Dead Coin Battery
The most common reason for a key fob that does not be able to lock or unlock your vehicle is a dead coin battery. It usually shows symptoms before it dies like a decrease in range or no power at all. It is easy to replace it with a brand new (CR2025) one from a local retailer. Be aware that using the wrong or incompatible batteries can cause damage to your key fob. Make sure that the new battery has identical in size, specifications and voltage as your old one.
If your fob has been exposed to clean water, for example rainwater or soapy tap water It is likely that corrosion has damaged the chip's electronic components. You could clean the chip with isopropyl or electronic cleaners to determine if that helps, but the chip is damaged.
The most efficient solution is to get an entirely new key fob. They are available from most major car dealers and are installed by a qualified mechanic. You can also buy them online, like on eBay. The best method is to work on a flat surface with good lighting. It is much easier to work on small pieces. It also allows you to avoid putting something in the wrong place. Always work on your key fob in a location that is secure and safe.
Water Damage
You may think your key fob is damaged if you drop it in the pool or accidentally wash it. There's a chance. When the circuit board inside the fob is exposed to water, it develops a conductor which shorts the components. It also speeds up corrosion and rust.
This is an easy solution. Simply locate something absorbent and put it inside the fob - a paper towl or tissue work well. Use a cotton swab that contains isopropyl to wash the circuit board, as well as any other components. Let replacement seat key dry out for several days in a warm and dry environment.
Once the fob is been drained, replace the battery with a new one of the same size and polarity ('+' that is pointing upwards). The fob can be difficult to open in order to access the battery, but if you keep a flat-head screwdriver in your toolbox, it should be easy to insert. After the fob is reassembled it should function in a normal manner. If it does not work then you might need to program it again or replace the module.
Radio Interference
If a key fob is functioning correctly, it transmits a radio frequency signal, which is received by the module inside your car. If the signal is not received, your key fob will not work. This may be due to things, weather conditions or other transmitters operating within the same frequency band close to your car.
In this instance it is recommended to replace the battery in your key fob. In this instance it is recommended to replace the battery in your key fob.
Some aftermarket LED lighting that utilizes the same frequency as a remote key fob could interfere with the signal and stop it from reaching the receiver modules. The LED's lighting needs to be turned off or switched to a different frequency to be able to avoid interference.
If the issue is still present after installing a new battery, the antenna of the key fob might be damaged or not functioning properly. The antenna is responsible for transmitting a signal between the key fob and the receiver module. An OBDII scanner can aid in identifying the issue by telling you what is wrong with the system. The scanner will ask you to provide information about your vehicle, including the make, model, engine type and VIN number.
Faulty Receiver Module
The key fob has a receiver module which transmits signals to lock and unlock the key fob. All electronic components on board will cease functioning if this component develops a problem. Reprogramming the keyfob using an OBDII scan, or replacing it can help.
There are several possible causes which could be due to the battery of the coin is dead, water damage or signal interference. You can reset the on-board computer by disconnecting the 12 volt batteries for 15 minutes. This will eliminate any remaining electric current that could cause issues. Start by removing the cable from the negative terminal first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order: positive first, negative second.
Dirt and water can harm the internal chip of the key fob. If your key quit working after getting wet, you need to clean the electronic component with isopropyl ethanol or an electronics cleaner before reinstalling the battery. If the key stopped working after exposure to soapy or salted water, it's likely that the chip is damaged and must be replaced.
Another possibility is an inoperable antenna module fuse, which transmits the signal to lock or unlock to the vehicle. The fuse could be found in several places, depending on the type of vehicle. For instance it could be beneath the rear seat, or in the trunk, or the side of the dashboard.
