Door lock beep/click

My daughter's 2004 Tundra has started random door lock beeping and clicking with the headlights flashing. Happens whether truck running or not.

 

Also ABS light comes on when it happens

 

Sounds like alarm or keyless module is going bad.

 

Having an 04, I'll ask if you have 2 remotes ?
Is this the same chirps/head light flashing when locking unlocking doors with remote ?

Lock doors....1 chirp/1 HL flash
Unlock....2 chirps/2 HL flashes
Wondering if your remote is being accidently pushed while in pocket or if 2 remotes, one is going south on ya !

 

We only have 1 remote. 2 beeps/flashes. It happens when engine off, when on, when driving and always with no warning. Tried new batteries and removed batteries from fob and made no difference.

 

Does it have an aftermarket alarm? I had to rescue my parents once whos aftermarket alarm randomly shit the bed in a parking lot and just kept going off disconnected it and everything was fine.

 

I agree. Picture of the remote would be helpful.
