Use a small flat-head screwdriver or a thumbnail (A) to open the battery compartment cover of the key fob (B). Replace the CR2025 coin battery to ensure that it is placed in the proper direction and polarity.

Dead Coin Battery

The most frequent reason for a key fob to not be able to lock or unlock your vehicle is a dead coin battery. It usually displays indications before it dies, like a decrease in range or no power at all. It is simple to replace it with a fresh one (CR2025) from an area supermarket. It is important to be aware that using the wrong or incompatible batteries could damage your key fob. Be sure that the battery you replace is the same size and voltage, and that it is the same specifications.

If your device was exposed to clean water like rain or soapy tap water it is likely that the electronic chip inside has been damaged by corrosion. You could try cleaning the chip with alcohol or an electronic cleaner to test if it helps, but it is more likely that the chip is damaged.

A new key fob is the simplest solution. They can be purchased from a variety of major car dealers and can be installed by a qualified mechanic. You can also buy them online, like on eBay. The best way to work is to work on a flat surface with good lighting. This makes it easier to work on the small parts inside. This will also help you to avoid putting something back in the wrong location. Always keep your key fob in a place that is safe and secure.

Water Damage

If your key fob gets submerged after dropping it into the pool or by slipping it in the washing machine, you may think it's over, but there's still hope. If the circuit board inside the fob is exposed to water, it transforms into conductor that shorts the components. It also speeds up corrosion and rust.

Luckily, this is a simple issue to fix. Find something absorbent to place inside the fob. A tissue or paper towel will work. Then make use of the cotton swab, dipped in isopropyl alcohol and wipe down the circuit board and other components to get rid of any battery acid residue or contamination. Allow the circuit board to air dry in a warm, dry environment for several weeks.

Replace the battery when the fob is dried out with a fresh one that has the same dimensions and the same polarity ('+' (pointing upwards). The fob isn't easy to open to access the battery, however If you have a flat-head screwdriver it will be a breeze to insert. After the fob is rebuilt, it should operate like a normal. If it doesn't work it may be necessary to re-program it or replace the module.

Radio Interference

If a key-fob is functioning properly, it emits a radio frequency signal that is received by the module in your car key programming Cost. If the signal is not received, your key fob won't function. This can be caused by objects such as weather conditions, objects, or other transmitters that operate on the same frequency in close proximity to your vehicle.

This can cause your key fob to not be able to activate the vehicle's functions like the ignition switch or security system. In this situation, it would be best to replace the battery on your key fob.

A few LED lighting products that utilizes the same frequency as a key fob for remote control may interfere with the signal, stopping it from reaching receiver modules. To prevent interference, the LED lights should be turned off or switched to the opposite frequency.

If the issue continues to persist after replacing the 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 for details about your vehicle, including the model, make engine type, VIN number.

Faulty Receiver Module

The key fob is equipped with an encoder module that transmits the signals for locking and unlock. All electronic components that are on-board will stop working if this module has a problem. If this is the case, reprogramming with an OBDII scanner or replacing the key fob itself could help.

There are several possible reasons for this problem such as a dead coin battery, water damage, or signal interference. You can reset your on-board computer if you disconnect the 12 Volt batteries for 15 minutes. This will draw out any remaining power that could cause issues. Remove the cable first from the negative terminal, then the positive terminal. After 15 minutes, reconnect your battery in reverse order. Positive first, then negative second.

The internal chip in the key fob can also be damaged by water or dirt. If your key fob stopped functioning after being soaked, clean it with isopropyl, or an electronics cleaner. Then, you can reinstall the battery. If the key stops working after exposure to soapy or salted water, it is likely that the chip has been fried and needs to be replaced.

Another possibility is a defective antenna module fuse, which transmits the lock or unlock signal to the vehicle. Depending on the model the fuse can be located in a variety of locations like the engine bay, the side of the dashboard, beneath the rear seat replacement key, or in the trunk.
