on my 2001 BMW X5, the entry key is not working and now the cylinder on the car is broken; i can not get in my car....Any suggestion?

Call a company like AAA to slimjim the door open and book vehicle in to dealership to get the key fob and cylinder replaced and coded to the car.

Thanks, unfortunately I called a locksmith and charged me too much and broke my lock trying to open; I had to help him to open it. I should had called AAA.
