To replace the battery in the key fob of the Bentley Arnage, the following tools are required:
- Large Flat Head Screwdriver
- Very Small Flat Head Screwdriver
The battery size required is CR1620. Follow the instructions in the video for more details.
I was able to purchase a 5-pack of these batteries on Amazon for $3.94. That breaks down to $0.79 for a single battery to fix the dead keyless entry remote. If all my other service items cost anything like this, this whole Bentley ownership should be a cakewalk.
