straight from the 2nd GEN OM
"POWER DOOR LOCKS
Press the top of the control to
unlock all doors and the bottom to
lock all doors.
When the vehicle’s security system
is armed, the power door locks and
remote trunk release control are
disabled; these features will not
work until the security system is
disarmed."
I wonder if you could run it through it's passes on the following,
"Central locking/Two stage unlocking
When unlocking the driver door with the key, turn it once toward the
front of the vehicle to unlock that door only, if the two-stage unlocking is
enabled. Turn the key a second time to unlock all doors. When locking,
turn the key toward the back of the vehicle to lock all doors.
Two stage unlocking may be disabled and re-enabled (to allow all vehicle
doors to unlock simultaneously) by simultaneously pressing the lock
and unlock controls on the remote entry transmitter for four seconds.
Note: The turn lamps will flash twice to confirm that a change to the
feature has occurred."
... just in the event that it's somehow affecting the interior switches.
See if it starts working normal as it used to after performing that enable/disable operation ... Not sure.
You'd think the interior door switches would just work as they should once one of the doors has been opened.
Guess there is a possibility that it's not meant to work if the keys have been out of the ignition more then 2 minutes.
Never really thought about it or even tried it, I'll have to check it out some day.
In reality one would think that when disabling the alarm by using the FOB as you approach the car, once disabled and drivers door is opened, the interior door panel lock or unlock switches all should just work.
