How to get into my car have lost key?
A good locksmith will help you, I am sure. I found very good one at https://replacementcarkey.org/ , he did his job for rather reasonable price, it took me some time before I found this company. Good luck, hope you solve your problem asap.
There are good ways and bad ways to do this, If you have the time and money call AAA or a local tow guy, they will come out and do this for a small fee, The bad ways can cause you to mess up your car or your window, but basically you find something small and thin, like a flat jack or a coat hanger and put it in near the window of the car it is an art to find the right place and not mess up the trim of the car, or mess up the window using a wedge.
