How to Replace the Key Fob Battery on the Opel Astra?

Model: Vauxhall Astra Astra H - Years 2004-2010
Part: Key

The key fob of the Opel Astra has a silver plastic top. This consists of two different parts clipped to the body of the fob. To replace the battery, you need to remove both parts, starting with the one on the back that can be detached by pressing the button just below it. Extract the mechanical key blade and then move to the front plastic part, which bears the Opel logo. Remove it with a gentle force, being careful not to break it, and then replace the battery (type CR2032) located underneath.
