Keyless lock not turn off headlights
 

It used to work. Lock the car, press 3 times, it would horn and all lights off.

But after I changed an auto-dimming mirror, no matter how many times press the lock button, it only flashes the turning light with small beep sounds, headlights and foglights still on, never off, and no horn.

What's the problem and how to solve here? The only thing I can imagine is somehow related to disconnected the battery while I was changing the mirror.

Thanks.

Did you accidentally switch the lights from Auto to the On mode?

Nope.

Did you do anything to the car prior to the lights not working? The feature can be activated by the dealership from what I was told. Or just turn it off manually before you step out of the car.

I have the "smart" key access on my FRS, but my lights turn off after 2 presses on the lock. Horn never sounds.

I only say "smart" because it's not really that smart....
