How can the security sensors in the roof liner be taken off without breaking anything? Thanks - Daniel

 

You mean the ones over B pillars? They are secured with plastic retainers, similar to the ones used on door trim. You can't really save them or at least its going to be difficult as hell, they are too brittle at this point and you'll need to replace them. I've pulled mine with the headlining off and still mangled them badly and one retainer snapped You can get new ones though and they are cheap and sensors with brackets are of course reusable and will be fine.
