Hi all,
Recently picked up my second 01 GTS and the previous owner had an Audiovoxx APS400 alarm system installed but it isn't functional.
My last Celica had a dealer installed unit that was essentially a "factory alarm" and controlled locks, etc.

My question is: if i remove this APS400 alarm altogether, does the GTS have programming where I can lock / unlock all locks at once using the key hole and does it auto-lock when in "drive" and then unlock when in "park"?

Right now it looks like it randomly locks/unlocks when using the key but sometimes all locks unlock and other times only the drivers door.
When I stop and park, all locks unlock regardless of if they were in lock or unlock state before.

Thanks for your feedback! Great forum!
