When I unlock my truck the interior lights and bed light turn on, but the parking lights do not flash. The parking lights flash when I lock it. That's good because I can't stand having the horn beep when I lock it and I turned that off.
Hold both the LOCK and UNLOCK button on your remote for a few seconds.
That will toggle between light flash or horn sound (this is for LOCK only).
Light flash or horn sound does not happened on UNLOCK.
My '05 always flashed the parking lights when I unlocked the doors and beeped the horn when I locked them. Now a week ago both have stopped. The horn thing I'm OK with but I liked the light flash when unlocking to know it registered. I tried the holding both buttons down thing but no change. Ideas?
