Make use of a small screwdriver with a flat head or a thumbnail (A) to pry up the battery compartment cover on the key fob (B). Replace the CR2025 coin battery, making sure it is in the correct direction and in the right polarity.
Dead Coin Battery
A dead battery on a coin is the most common reason of a key fob not locking or unlocking your vehicle. It will usually show warning signs prior to dying like a decrease in range or no power at any time. It is simple to replace it with a new (CR2025) one from your local store. It is important to be aware that using the wrong or incompatible batteries could damage your key fob. Be sure that the replacement 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 by corrosion. You can clean the chip using isopropyl or electronic cleaners to determine if that helps, but it's likely the chip is fried.
A new key fob is the easiest solution. Most major car seat key dealers sell key fobs and they can be installed by a seasoned mechanic. You can also purchase them on the internet, for instance on eBay. The best way to work is to work on a level surface with adequate lighting. It makes it easier to work with small parts. You will also be able to avoid placing something in the wrong place. Always work on the key fob in a secured and safe place.
Water Damage
You might think that your key fob is destroyed if drop it in the pool or accidentally wash it. However, there's still a chance. When the circuit board on the fob is exposed to water, it transforms into a conductor that shorts out the components. It also accelerates the process of corrosion and rust.
This is a simple solution. Find something absorbent to place inside the fob. A tissue or paper towel will be ideal. Then, use the cotton swab, dipped in isopropyl alcohol and wipe down the circuit board and other components to get rid of any residue of battery acid and contamination. Allow the circuit board to air dry in a warm, dry environment for several weeks.
Replace the battery when the fob is dry with a fresh one that has the same size and polarity ('+' (pointing upwards). It can be tricky to open up the fob to access the battery but if you have a small screwdriver that is flat handy it should slide in easily. Once the fob has been rebuilt, it should operate just as normal. If it doesn't, then you'll need to reprogramme it or replace the receiver module.
Radio Interference
When a key fob functioning properly, it sends the radio frequency signal which is interpreted by the receiver module inside your seat car key cover. If the signal is disrupted, your key fob will not work. This can be caused by objects or weather conditions, or other transmitters operating on the same frequency near your vehicle.
This can cause your key fob to not be able to activate the vehicle's functions for example, the ignition switch or the security system. In this instance it is best to replace the battery inside your key fob.
Some aftermarket LED lighting that utilizes the same frequency as a remote key fob might interfere with the signal, preventing it from reaching the receiver modules. To avoid interference, the lighting must be switched off or switched to a different frequency.
If you have a brand new battery in your key fob, and the issue persists, it is likely that the antenna on your key fob is damaged or not functioning properly. The antenna is responsible for transmitting signals between the key fob and the receiver module. The OBDII scanner is able to aid in diagnosing the issue by telling you what is wrong with the system. The scanner will ask for details about your vehicle including the make, model, engine type and VIN number.
Faulty Receiver Module
The key fob is equipped with the receiver module which transmits the signals needed to lock and unlock. All on-board electronic components will cease to function if this module develops a problem. If this happens then reprogramming the module using an OBDII scanner or replacing the key fob may help.
This problem could be caused by a dead coin-cell battery either from water damage or signal interference. It is possible to reset the on-board computer by disconnecting the 12 Volt batteries for 15 mins. This will draw out any remaining power that could be causing issues. Start by removing the cable from the negative terminal first, then the positive terminal. After 15 minutes, reconnect your battery in reverse order. First, positive and then negative the next.
The internal chip in the key fob can also be damaged by dirt or water. If your key's function stopped after it got wet, wash the electronic component with isopropyl Alcohol or an electronics cleaner before installing the battery. If it stops working after exposure to salty or soapy water the chip may be damaged and must be replaced.
Another possibility is a damaged antenna module fuse that is sending the lock and unlock signal to the vehicle. The fuse can be found in a variety of places, based on the type of vehicle. For instance, it could be under the rear Seat mii replacement key, or in the trunk, or the side of the dashboard.
