Most locksmiths, but not all, will let you back in your car should you lock your keys inside. Like I said in an earlier post, the average response time is between 15 and 25 min. give or take based on traffic. When you call we will get a detailed description of the vehicle and where it is located. When our tech arrives he will first locate the vehicle, then when located and positive ID made will look inside to see if the keys are visible, "NOTE" if the keys are visible he will then open the car and remove the keys. YES even if you are not at the vehicle. The reason for this is YOUR protection, there are a lot of crooks out there that would break the window and drive away in your car. So I strongly suggest that you not leave your car unattended. If you must leave, to get to a phone, to call a locksmith then try to have someone else watch your car for you or after you call get back to your car as soon as possible or at least be in a place where you can watch your car. I can't STRESS this STRONGLY enough, HERE'S WHY - Back in 1997 I was called out to unlock a guys car, upon arrival I found the car and saw the keys in the ignition, then went into the office building to locate the owner. When the owner and I returned outside the car was gone with only a pile of glass on the ground. The car had been stolen. So now it is our policy that if the keys are visible and there is nobody around, We will unlock the car and remove the keys. Then try to locate the customer or will wait by the car until the customer returns.
