The auto lock function on my 18 ASPEC hasn't worked properly, almost, since I bought it new in April of 18. I have changed the battery on the fob and that has helped, however, it still doesn't lock automatically from time to time and my local Acura dealer is absolutely useless. Occasionally when I shut the door, leaving, it immediately sounds a very quick successive beep. (When working it's just one beep) I have to reopen and shut the door or lock it with the fob. It's left me fairly paranoid to just walk away, after closing the door. I find myself waiting to hear what kind of beep it's going to emit Any suggestions? The dealer, of course, says they can't replicate it.
