Modern cars are full of electronics, and a key fob is no exception. Inside, it has an electronic chip that works as a transmitter; it transmits the signal when you press the button to open the door. The key fob is powered by a little battery. The battery may last for 2-3 years in a smart key fob and for 4-6 years in a regular fob with the key.The reason for this difference is that the smart key fob also has a receiver and has to communicate with the car more often when it’s inside or near the car. In most cars, a key fob battery is not rechargeable, and must be replaced once it loses its charge.As the fob battery becomes weaker, the transmitter loses its range. This means that you have to be closer to the car for the fob to work. In cars with a push button start, a vehicle may not always recognize a smart key fob in your pocket or purse if the fob battery is weak. In some cars, a warning message “key fob battery low” may also pop up on the driver’s display.In most cars, the security (immobilizer) chip inside the fob works without a battery, but only from a very close range. So even if the fob has a weak battery, it should still start the car. You may have to hold the smart fob closer to the “Start” button or insert it into a special slot to start the engine. Check your owner’s manual for directions. A conventional mechanical key might also be stored inside the fob. This key can open the driver’s door in case the fob battery is dead or if the main battery in a car is discharged.In many cars, a key fob has a little LED light that illuminates when pressing any of the fob buttons. If the LED light doesn’t light up at all, the fob battery is dead or there is some other problem with the fob. If you already have the fob battery out, you can check its voltage with a voltmeter. The voltage is marked on the battery.If it’s a 3-Volt battery, and it shows less than 3 Volts, it’s weak. For example, this 3-Volt battery in the photo shows only 2.8 Volts; it’s bad and must be replaced.What kind of a battery does a key fob take? Different cars use different batteries. The most common types are CR2025 and CR2032 3-Volt batteries. You can find the exact type in the owner’s manual. Batteries like this are sold in any electronics store or at a dealership.Changing the fob battery is not very difficult. Check the owner’s manual for the instruction and precautions. There are plenty of Youtube videos on how to do it too. You might need a small flat or Phillips screwdriver.For example, to open the key fob in the top photo, we pried it open with a little flat screwdriver in places indicated in the owner’s manual. Be careful; the plastic tabs that hold the parts of the fob together break easily. In some cars, there could be some tiny screws or other parts that are easy to lose.When replacing the battery, watch for the way it’s installed. One side of the battery is marked with the “+” sign. It’s important to install the new battery the same way, or it won’t work.If you are not mechanically inclined, visit your dealer; they should be able to change the key fob battery for you. Typically it doesn’t take more than a few minutes. We checked with several dealers and the prices we got were within $10. A key fob doesn’t need any programming if only a fob battery is replaced.

How To Change Keyless Remote Battery

Changing your car’s low remote batteries can be very easy, but you must ensure that you get the appropriate battery for the remote and fix it correctly so that it can work. These steps will help you change your car’s low or dead keyless remote battery.

Step 1: Open the fob/remote: Once you get the correct battery for your car’s keyless remote from a reliable automobile accessories dealer, the first step is to open the remote. It’s pretty easy to know how to open the key fob to replace the battery.

To do this, use an object that can help you to pry the remote open carefully. You probably may not be able to open it with your hands. Ensure first to loosen the screw holding the two parts together (if any).

Step 2: Remove the old battery: After opening the remote, ensure to check how the original battery is placed, taking note of the positioning and the signs facing up on the battery. The batteries are typically round and fixed in a rounded position.

Once you note the correct position of the battery, remove the old battery by first sliding it out (if there is an open space by the side). If that doesn’t work, check out for any clips that may be holding the battery in place; then, carefully push the clips aside, and slide out the old battery.

Step 3: Fix the new battery: After removing the old battery, fix the new one with the old battery’s same order. You see why you needed to take note of the position of the old battery!

Step 4: Close/lock the keyless remote/fob: Once you correctly fix the new battery, proceed to reverse the process you used in opening the remote to enable you to lock it back. Ensure that you observe the holes and the sides pointing into them to fix them correctly.
