This system is very troublesome. I bought it to put in my Infiniti G37, thinking it would make the install easier. Unfortunately for me, after 20+ hours of being at a Certified Viper installation center, they said that they were unable to get the DLPK working properly with the Viper 5901.
I ended up having to suck up the cost of the Viper 5901, the DLPK, and over[..] in non-refundable labor. After that, they put in a Hornet 727T which worked right out of the box, installed in less than two hours with all the extra modules i bought.
All in all, this DLPK module is not recommended for Infiniti g37's, although it says full compatibility on the [...] website.
Don't be fooled like i was.Get more detail about Xpresskit Optimax Series DLPK Canbus Door Lock and Passkey Interface.
