Car Key Replacement and Safety Tips

It is expensive to replace the car key for newer model vehicles. Some dealerships charge $200 and up to replace a key. The expense is not from cutting the car key, which only costs a dollar or two in time and parts, but from programming the electronic chip in your vehicle's key. If you have a perfectly cut key without the programming for the chip, you can put it in the ignition and turn the car key but the car's engine will not start.
