It could be a worn-out button, as an example. This will only make the button work infrequently and not always.

Interference

The key fob is powered by a small transmitter that sends out an extremely short-range signal to a receiver located in your car. Its goal is to enable your car to recognize the key fob and open its doors as you approach it, and then start when you press the ignition button.

Interference can sometimes interfere with communication. For instance, if you have your second-generation Apple Pencil charged while you're holding the fob, it might stop you from unlocking your car (via iGeneration).

Other electronic devices that operate on the same frequency may also interfere with the fob's signal. This can include garage door openers, as well as tire pressure monitoring systems. It's even possible that an RF receiver inside your home might be interfering with the fob's signal, however, this is difficult to pinpoint without an examination by a professional.

Your key fob might need to be reprogrammed. The transmitter on your key fob has to be recognized by mini keys's receiver. A unique code is used for each pairing. Fobs need to be reprogrammed after they have been disconnected or replaced after you buy a new one and in some cases when the battery is changed.

The issue is usually fixed by replacing the battery which is affordable and easy to find at a hardware store or big-box retailer. Make sure to purchase the right replacement battery compatible with your specific model of car to avoid recurring issues.

It is also important to ensure that the fob isn't exposed to water or soapy residue. Water can cause corrosion and interfere with the circuitry. If this is the case, you will have to wash it by using isopropyl or electronic cleaner before putting in an entirely new battery.

It is a good practice to test the functioning of the fob prior to driving the vehicle. Using a voltmeter, check the voltage of the replacement battery to determine whether it's at a safe level. If not, you might require replacing the entire remote chip. A trained technician from a dealership can help you choose the best solution for your vehicle.
