The first thing you'll need to do is find out what kind of battery your key fob uses. This information is typically found on the manufacturer's website or by looking at the key fob. Generally, the most common battery that is used in key fobs is a button cell that is similar to the ones used in watches and remote controls. These types of batteries are found at stores such as Walgreens and Energizer and can be bought for less than $5 for a set of two.
You can take the old battery off your key fob after you know the type of battery it has. Most key fobs are designed with a notch or seam between them and can be opened by using your fingers or with a flat tool like a screwdriver. When the fob is opened, the battery should be able to pop out and you can then insert the new one in the same direction as the old one. Many key fobs are powered by CR2032 batteries. These batteries can be found at stores that sell AAA or AA batteries.

Reprogram the Key Fob
If your key fob won't work and you think it's time to replace it the fact is that it might not require the replacement of a battery, but instead the old one has to be reprogrammed. This procedure varies for each vehicle and the best option is to read the owner's manual (usually available in PDF format on the site of the automaker) or look on YouTube for videos that explain how to accomplish this.
The majority of modern vehicles require a specific procedure to put the vehicle into 'programming mode,' which is usually done by pressing the power button on the driver's side door or ignition several times while pressing a button on the fob within a specific time period. This is how the fob sends its digital identity code to the vehicle, and it stores it in memory. The fob functions as a regular key after it is programmed.
It is important to remember that changing the programming of a key fob will wipe out any other key fobs which have been previously programmed. If you wish to keep the other fobs after the first, then they should be programmed quickly and with care.
Sometimes, you can find replacement batteries for car key fobs in hardware stores, big retailers, or even online. It is important to know the make and model before you purchase a fob because it can be difficult to locate the right battery.
