Let’s see how to change the battery in the key of an Opel Astra (or Corsa, the procedure is the same). As this is a German video, our YouTuber is very meticulous and tests the battery with a voltmeter after removing it from the remote.

To do this, he only had to lever with a small screwdriver to pop off the top cover. The internal battery is a common CR 2032, which you can easily find at a newsagent or supermarket for a few pounds.

When replacing the new battery, pay attention to the polarity. Then close the key, and the job is complete.
