What to Do If You Lose Your Car Electronic Key?

[ArabellaLee]

First, notify the 4S dealership to deactivate the original car key. Once deactivated, the original key can no longer start the engine. If only the key is lost and you still have the vehicle's registration certificate and your driver's license with you, you can try calling a locksmith to open the car door. If all your documents are locked inside the car, have someone watch the car while you quickly retrieve the spare key. Finally, if you can't find the spare key either, you'll need to get a replacement key. You can have a new key made at the 4S dealership or at a small roadside repair shop.
