Finding yourself locked out of your car is a terrible feeling. Matters are much worse when you only have the one key. You must find out if your car has an electronic chip in the key before you get into this situation.
Read over the information in your car’s owner’s manual. It should give you information about your car’s ignition system and whether or not your car keys contain an electronic chip.
Call the car dealership where you bought your car. Your salesperson should be able to give you information about your specific car keys.
