If your car already comes with a keyless entry or remote car starter system, you might want to check your dealer regarding the coverage of their warranty and insurance. Most dealers include free battery replacement to their customers. This way, you won’t have to spend money for new batteries plus, a professional from the shop will do the replacement job for you. All you need to do is to bring your transmitters.

Know the battery number of your remote car starter

If the warranty or coverage does not include battery replacement, then resort to replacing them by yourself. To make sure that you are buying the right battery for your remote, it is better to read what is written on the previous battery. First, open the key fob on the back and remove the battery. See to it that you are opening the fob the right way because every model differs. Also, remember that not all battery cells will work on the same remote or fobs. So, once you get the battery out, look for the unique code on the cover or outside of the battery. The common code of lithium ion cell is CR2025. If you cannot find it, you can research online or call your dealer.

Buy the same battery model

The safest way to avoid making a mistake when replacing batteries is to buy the exact same model. You can bring the old batteries to the local shop and let the dealer take care of finding them for you. If you buy a battery made by a different brand without checking the codes, it might not work with your remote and cause problems like leakage. For example, all 3-volt cell batteries have the same size and can fit in one fob, but it doesn’t mean that they are the ones you are looking for.

Use rechargeable batteries or buy in bulk

If you never want your remote car starter to run out of batteries, then buy them in bulk. They are cheaper that way and you don’t have to run to your local shop every now and then. Aside from this, the batteries will surely work with other electronics, so buying in bulk actually makes sense. Store the batteries properly in a cool and dry area to preserve the battery life. Another option you have is to use rechargeable batteries.

Now that you’ve purchased a new battery for your remote, it’s time to learn how you actually replace it. The first step is to remove the back cover or wherever the battery cover is found. Most models are found at the back, and you have to use a coin as a screwdriver to remove it. If yours is different, then you might need an actual screwdriver to open it.

After removing the cover, study how the dead battery is placed before removing it so that you know how you should place the new one.

Once you replace the battery, put the cover back in place then try pressing the buttons to see if the car will respond.
