How to Unlock a Car Door That's Been Locked from the Inside?

[FrankAnn]

Find the spare key provided by the 4S store when you bought the car or retrieve the spare key, which is the simplest and least costly method. You can contact a locksmith company to unlock the door, which allows you to open the lock without damaging the vehicle itself, though it may cost some money. For safety reasons, you can contact the local 110 for assistance in recommending a qualified locksmith company.

I've got experience with this situation! Don't panic yet, try pressing the unlock button on the remote key fob three to five times in a row. If the remote doesn't respond, it's most likely the key battery is dead. Take out the metal part of your spare key - there's a small indentation or keyhole above the driver's side door handle. Insert the key and turn it half a circle to open. Can't find the keyhole? Use a long hook or wire, slide it along the gap at the top of the window seal (don't worry about marks, the rubber seal is flexible), and gently hook the interior door handle to pull it up. Older cars often have hidden keyholes in the rearview mirror base - turn clockwise to open in emergencies. If all else fails, call a locksmith - much cheaper than forcing the lock!
