Can a locksmith replace a car key?

In today's world the method above is slightly outdated. The real answer is; it truly depends on what car you have. If you have a newer model (2005 or higher) you may need a professional locksmith to program the chip to the new car key. If you have an older model you will need a locksmith to look up your key code to make you a new car key. You can call your automobile dealership but they will charge you 5X the amount than anyone or anywhere else. If you have a push start, that can be tricky. BMW, Mercedes and luxury cars may have proprietary car keys so you will need to check with a professional to get an exact answer.
