How do you open trunk of a 1998 e36 if the lock is jammed?

If the trunk lock on a 1998 BMW E36 is jammed, you can try using a lubricant like WD-40 to spray into the lock mechanism to loosen any stuck components. If that doesn't work, you can access the trunk from the back seat by folding down the rear seats and reaching through to manually pull the trunk release lever or latch. If these methods fail, consider using a slim jim or a coat hanger to unlock the trunk, but be cautious to avoid damaging the vehicle. If all else fails, consulting a professional locksmith or mechanic may be necessary.
