What can I do if I locked my car key inside my car?

Do you have a spare key?  Can you get inside the car in any other way?  I recommend calling a locksmith, if you can find one on your way home.

Yes, those are all plausible solution. Did you know on newer cars you can actually call a customer service line and have them remotely unlock your car if you can prove you're the owner?

Yes, that's an interesting and useful feature!  Do you know which of the cars you own has that feature?

That’s a good idea!  It’s also possible to call a locksmith and have him open your car with a specific code, if you give him your phone number.
