Battery

The most simple way to fix the battery on your key fob is to replace it. The device uses a small coin-shaped 3V battery (CR2032 or CR2025) that is available in general stores and home improvement stores, and some auto parts stores. You should use a new battery. Old batteries can cause damage to the circuit boards and become less useful.

Begin by opening the fob. You may have to make use of a flat screwdriver to split the two halves. Install the screwdriver into the seams on both sides of the fob and lift the clips that hold it. They are easily broken so be cautious and work slowly.

After replacing the battery, reassemble the fob and examine it to determine if everything is functioning as it should. If it isn't working after pressing the button a few times, check that the contacts are clean. You can also try it with a spare key fob to determine if the issue is isolated to that particular key. If not, then there could be another reason for the key fob to not function. It could be due to a worn button, for example. This would trigger the button only occasionally, not all the time.

Interference

The key fob is a tiny transmitter to send an audio signal that is short-range to a receiver inside your vehicle. Its purpose it to allow your vehicle to recognize the key fob and open its doors when you are near it and start when you press the ignition button.

The issue is that interference can interfere with the transmission. 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 at the same frequency can also interfere with the fob's signal. This includes garage door openers, as well as tire pressure monitoring systems. A transmitter in your home could be causing interference, but this would be difficult for a professional to test.

It's also possible that your key fob needs to be reset. The transmitter in the fob you have purchased must be recognized by mini key fobs (resource for this article)'s receiver. A unique code is then generated for each pairing. The fobs will typically need to be changed when they're removed or replaced, if you purchase a new one or, in certain cases, when a battery is changed. Follow the steps in the owner's manual for how to change the programming of a key fob. You can also seek assistance from a dealer.

Chips that aren't working

Modern electronic key fobs offer more convenience and functionality than traditional manual keys. However they also are more prone to damage. One of the most common issues is a damaged chip that can stop your device from functioning properly. Fortunately, it's usually an easy fix.

If your car key fob isn't able to start up it could be the result of a faulty chip. The issue can be fixed by replacing the battery which is cheap and easy to find at an hardware store or big-box retailer. Make sure you purchase the right replacement battery compatible with your specific model of vehicle to avoid any further issues.

It is also important to make sure that the fob is not exposed to water or soapy residue. Water will often cause corrosion, which can cause interference with the circuit board. If this is the case, you'll need to clean it with isopropyl alcohol or electronic cleaner before putting in the new battery.

It is a good practice to test the operation of the fob prior driving the vehicle. Using a voltmeter, check the voltage of the replacement battery to determine whether it is at a safe level. If not, it could be necessary to replace the entire chip in the remote. A qualified dealership technician can help you determine the best solution for your car.
