Battery

Switching the battery on your key fob is one of the most straightforward fixes.

Make sure to use a new battery. Batteries that are old can damage the circuit boards and become less useful.

Install the screwdriver into the seams on both sides of the fob, and lift the clips that hold it in place. They are very easy to break therefore, proceed slowly and with care.

After replacing the battery replace the fob, then check to see if everything is working just as it should. If it's still not working try pressing the button several times and checking whether the contacts are clear.

It could be a worn button, for example. This would only cause the button to function only occasionally, not all the time.

Interference

The key fob is powered by a tiny transmitter that sends out the signal in a short distance to a receiver located in your car. Its goal is to enable your vehicle to recognize the key fob and open its doors when you come close to it, and begin when you press the ignition button.

Interference may sometimes hinder communication. For instance, if are using your second-generation Apple Pencil charged while you're holding the fob, it could hinder you from unlocking your car (via iGeneration).

Other electronic devices that operate on the same frequency as the fob could interfere with the signal. This can include garage door openers, as well as tire pressure monitoring systems. Even a transmitter at your home could be causing interference however this isn't easy for an expert to test.

It's possible that your fob needs to be reprogrammed. The transmitter on the fob you have purchased must be recognized by the mini lost key's receiver. A unique code is then generated for each pairing. The fob needs to be programmed after being disconnected or replaced after you purchase a replacement or in some cases, when the battery is changed. Follow the steps in your owner's manual to change the programming of a key fob. You can also ask a dealer for assistance.

Chips that aren't working

Modern electronic key fobs provide convenience and performance over traditional manual keys, however they can also be more susceptible to damage. A defective chip is among the most common issues that can prevent the key fob from working properly. It is usually a simple fix.

If your car key fob doesn't seem to turn on, it could be an indication of a defective chip. The issue can be solved by replacing the battery, which is affordable and easy to find at an hardware store or big-box retailer. Be sure to buy the right replacement battery compatible with the model of your car to avoid further issues.

The fob shouldn't be exposed to water or soapy residue. Water can cause corrosion and affect the circuitry. If this is the case it is necessary to clean the board with isopropyl and electronic cleaner prior to installing an entirely new battery.

When the old battery is replaced, it is recommended to test the functionality of the fob before driving the car. With a voltmeter, test the voltage of the replacement battery to see whether it's at a safe level. If not then it may be necessary to replace the entire chip in the remote.
