Wagon R remote car key battery change

[depisode]

Aoa,
What's the standard procedure to change any car remote battery? Do I take it to the dealership? Or to my auto electrician (trustworthy person) or do people usually change it themselves at home?
[Edit] just to make it clear , this is the battery in the car key I am talking about.
Thank you

You can take it to the dealership, You can take it to your electrician or you can do it yourself. Most of the watch shops will also replace it, Whichever way you go just make sure to use a good quality battery. If you're going to do it yourself then watch the following video for instructions: https://www.youtube.com/watch?v=TBA_4Z_7hMk
