Yes, you can. DIY is quick, simple, and cheap. To do this, pry apart the key fob and replace the coin battery inside with a new one.

For your remote key fob to work properly, it has to be connected to a receiver in the vehicle. When the battery in the fob is replaced, it can sometimes interfere with the paired connection between key and car, in which case you'll need to reset it.
