08 expedition el. When locking or unlocking the vehicle using the remote entry device, the horn chirps multiple times for verification. Could someone refer me to a manual (other than the owner's guide) that will give directions on how to remove the chirping sounds when locking/unlocking the vehicle? Thank you

 

I don't have an after market alarm just factory with that said, if the rear gate glass or any door ajar, the horn chirps a few times to notify you.

This has been my experience with my 2007 XP EL
Hope this helps.
