2005 nissan altima dei 451m

What is the make and model of your after market system? Since your factory door locks are controlled by low current negative pulses you probably do not need the 451M in the 05 Altima.Installer, IT support, and FFL. I need less hobbies.

Viper 771xv with remote start

No need to use the 451M....your unit offers negative pulse outputs for door locks.
