Update. How to disable keyless entry chirp?

Is it possible to disable the lock/unlock chirp sound?

Update*** Nevermind, I think I have the answer which is, no and yes. Yes if you have the Toyota Techstrem SW and J1962 cable. I'll see what the dealer says when I go in for the 1st oil change.

Or you can get a stereo unit that supports iDatalink Maestro and that way you can adjust all of your factory features via your stereo. That's what I did, check it out:

Yes, the dealership is the answer. There's other things that you can customize as well, the list is in the manual.
