Change the Battery
It may be time to change the battery in your key fob if it no longer works as it should.

The most common kind of battery that is found in a keyfob is the button cell that is similar to the ones used in watches and remotes. These batteries are available at Walgreens, Energizer and other stores for less than $5 for a pack of two.
Once you are aware of the type of battery your key fob is using you can open it and remove the old battery. You can open most key fobs by using your fingers or a flat tool like a screwdriver, at the notch or seam where they connect. After the key fob has been opened, the battery will be released. You can then replace it in the same orientation. The majority of key fobs are powered by CR2032 3V batteries, which are easily accessible at a variety of retailers that sell AAA and AA batteries.

If your car is not responding to the key fob, it may be necessary to reprogram your key fob and establish an electronic connection between the two. This is a relatively easy process that requires your phone or a different device.
Reprogram your key fob
If you're experiencing issues with your key fob, and you think it's time to replace it however, it may not be required to replace it. Instead the old battery might require reprogramming. This procedure is different for every car so the best way to find out is to consult the owner's manual (usually accessible in PDF format on the automaker's website) or search YouTube for videos on how to do this.
The majority of modern automobiles require a particular procedure to put the vehicle in "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 specified time. This is how the fob communicates its digital identification code to the car, which saves it in its memory. Once the fob is programmed, it can behave as normal keys.
It is important to remember that changing the programming of a key fob will erase any other key fobs which have been previously programmed. Therefore, if you want to keep other fobs, they must be reprogrammed with care and speed following the initial one.
Sometimes you can find replacement batteries for car key fobs at hardware stores, large retailers, or even online. However, you must be aware of the model and make of your car prior to purchasing a battery for your fob because the correct type of battery can be difficult to locate.

Certain European automobiles, like the ones manufactured by Audi and BMW generally require a dealer to get this service due to the fact that they have special security features that can only be reset by the manufacturer. Certain dealers, like those at Toyota and Lexus were willing to reprogramme the key fob in a replacement if you knew the exact model and brand of your vehicle.
