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.
