Passenger Side Door Won't Open from Outside?

[LeArabella]

Possible causes for the passenger side door not opening from outside: 1. Central locking system is engaged: Try unlocking/locking twice with the key, then press the unlock button on the master control panel (located on the driver's side front door trim). 2. Child lock is activated: Always check child lock status before closing doors. If stuck, use a flathead screwdriver to deactivate it. 3. Door lock cable failure: This prevents both interior/exterior access as it directly disables the locking mechanism. 4. Door hinge/lock post deformation: External impacts may cause structural misalignment. 5. Door check strap malfunction: Requires replacement of the entire door check assembly.
