A:AnswerYou can actually still use your old key to get in your car after installation. And yes, there is trunk unlocking feature on this one , but it might depend on your car as well.
A:AnswerI would call up your local BB. Some of them are not scheduling still due to covid. I called to ensure I would get my free install since I received no notification after online order. I found out that my local BB does not yet do installs due to covid so I scheduled it for the next town over. The BB rep told me as long as it was ordered off their site, the install is free. Good luck!
