To remove the outer door handle on a 2008 Saturn Aura, first, ensure the door is open and locate the screws securing the handle, typically found in the door panel. Use a screwdriver to remove these screws, then carefully pry off the door panel to access the handle mechanism. Disconnect any linkage attached to the handle, and finally, slide the handle out of its housing. Reassemble in reverse order after replacing or repairing as needed.

To unlock a Saturn Aura with keys inside, you can use a slim jim or a lockout tool to try and manipulate the locking mechanism through the door frame. Alternatively, if you have access to a coat hanger, you can attempt to reach the lock or door handle. If these methods are unsuccessful, calling a locksmith or roadside assistance is advisable to avoid damaging the vehicle. Always ensure to check local laws regarding vehicle entry.
