Most modern cars won't run with out the master key
(they have a transponder chip inside the key that the car recognizes when you try to start it)
If your worried about the car and you don't already have an alarm you could get an after-market alarm fitted, reason being you can double lock the car
(first with your own key and then with the remote control from the new alarm)
Getting locks changed on a newer car can be very expensive, not worth it really
plus an after-market alarm is a great re-sale pointHow much does it cost and where can i get my car door locks changed?
Why don't you just get the key back?How much does it cost and where can i get my car door locks changed?
Go to a car parts store and get a new lock set, do it yourself and save.
or go to your dealer and get screwed over like your X
