I recently had a new starter installed on my 2000 Tacoma with the factory alarm/security system.
Since that time, the alarm system is behaving annoyingly.
If I shut the truck off and do not lock the vehicle with the remote after a short period of time (one minute, perhaps?) then the truck will "beep" and the alarm system will arm itself, but the doors do not lock.
If I open the door without "unlocking" it with the remote, thus deactivating the alarm, the alarm sounds.
This is highly annoying. I do not remember setting the system not to arm itself in this matter after I bought the truck, but perhaps I did.
Anyway, I can't figure out how to disable this annoying "feature" and the owner's manual is packed away somewhere. Anyone have any ideas?
