How do you open front door on citroen C4 when handle is broken?

If the handle on your Citroën C4 is broken, you can try using the key to unlock the door manually. If that doesn't work, you may need to access the door through the rear door or the trunk to reach the internal mechanism. Alternatively, you can use a flat tool to gently pry open the door frame and manipulate the locking mechanism from inside. If these methods fail, it's advisable to consult a professional locksmith or a mechanic for assistance.
