06 Corolla w/keyless do headlights flash???

Hi guys, i'm in a situation where a customer claims that on his 2006 fully loaded corolla that when he hit the lock button on his keyless remote the parking lights aswell as the headlights would flash! I know that the parking lights flash but never paid attention to the headlights, so if someone could please let me know if the headlights are supposed to flash!!!

Thanks in advance.

May be apples and oranges but, my 06 RAV 4 headlights don't flash. Just the parking lights.

I have a 2006 Corolla with keyless entry. The headlights do not flash. I asked the dealer about the horn chirp and he said that it could be programmed to do that. Maybe the headlights can be programmed to flash when you hit the lock button also.
