Make use of a small screwdriver with a flat head or a thumbnail (A) to pry up the battery compartment cover of the key fob (B). Replace the CR2025 coin battery and ensure it is in the correct direction and polarity.

Dead Coin Battery

The most frequent reason for a key fob that does not unlock or lock your car is a dead coin battery. It usually displays symptoms before it dies such as a decreased range or no power at any time. It is simple to replace it with a new (CR2025) one from a local retailer. It is important to be aware that using the wrong or incompatible batteries could damage your key fob. Make sure the battery you replace is the same size and voltage and also the same specifications.

If your fob was exposed to pure water, such as rainwater or soapy tap water It is probable that corrosion has caused damage to the electronic chip. You could clean the chip with isopropyl or electronic cleaners to see if it helps, but it's likely the chip is fried.

The most efficient solution is to buy an entirely new key fob. The majority of major car dealers sell key fobs and they can be installed by a skilled mechanic. You can also purchase them online, such as on eBay. It is best to work on a work surface that has good lighting. It is easier to work with the smaller parts. You'll also be able to avoid placing things in the wrong place. Always keep the key fob in a secure and safe space.

Water Damage

If your key fob gets soaked by dropping it in the pool or fumbling it in the wash, you may think it's a goner but there's hope. When the circuit board in the fob is exposed to water, it develops a conductor that shorts out the components. It also speeds up the process of rust and corrosion.

This is a simple fix. Find something absorbent to put inside the fob. A tissue or paper towel would be a good choice. Then, use an alcohol-soaked cotton swab and a cotton swab isopropyl ethanol to wipe down the circuit board and other components to remove any residues of acid from batteries and contamination. Allow the circuit board to air dry in a dry, warm environment for several weeks.

Once the fob is dried out and the battery is replaced with another one of the same size and the same polarity ('+' that is pointing upwards). It can be difficult to open the fob to reach the battery, however if you have a small screwdriver with a flat head available, it should be able to slide into easily. Once the fob is reassembled, it should work as normal. If it fails, you may have to program it again or replace the module.

Radio Interference

If a key-fob is functioning correctly, it transmits an audio frequency signal that is picked up by the receiver module inside your car. If the signal is not received the key fob won't function. This can be caused by objects such as weather conditions, objects, or other transmitters operating on the same frequency near your vehicle.

This can cause your key fob to not be able to activate the car's systems such as the ignition switch or security system. In this case, it would be best to replace the battery inside your key fob.

A few LED lights that are aftermarket and uses the same frequency as the remote key fob may interfere with the signal, preventing it from reaching the receiver modules. The LED's light source must be turned off or switched to a different frequency in order to avoid interference.

If you've got a new battery on your key fob but the issue persists, it's possible 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. An OBDII scan will assist in diagnosing the issue by revealing exactly what's wrong with the system. The scanner will ask for details about your particular vehicle including the make and model along with the engine type and VIN number.

Faulty Receiver Module

The key fob has an electronic receiver that sends the signals for locking and unlock. If the receiver module fails and the on-board electronic components will stop functioning. If this happens, reprogramming with an OBDII scanner or replacing the seat key fob could help.

There are a few possible reasons for this problem that could be the cause, such as a dead coin battery water damage, or signal interference. You can try resetting the on-board computer by disconnecting the 12 volt battery for 15 minutes. This will remove any remaining electric current that could cause problems. Begin by removing your cable from the negative terminal first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.

The internal chip in the key fob can be damaged by dirt or water. If the key fob you purchased stopped working after being wet, wash it using isopropyl or an electronic cleaner. Then, you can reinstall the battery. If the key ceases to function after being exposed to salted or soapy water, it is likely that the chip has been damaged and needs to be replaced.

A defective antenna module fuse could be a cause. This is the fuse that sends an indication to the vehicle to lock or unlock. The fuse could be found in various places, based on the type of vehicle. For example it could be located under the rear Seat key transponder programming, or in the trunk, or the side of the dashboard.
