I think the simplest solution is too get rid of the SKREEM altogether, toss it out the window. It being replaced with a gizmo that cares nothing about key codes, chips and halos etc. It just connects all the systems to get the car running. A simple kill switch hidden away and the car unlocked manually with just a key with no fob. The pump in the trunk just unlocking all of the locks at once. No lights fading away seconds after locking the car. Back to basics.
What I say above may be harder than I think but .....
I guess it is OK for me to say this as I do have a spare SKREEM, two keys and too many years on my time clock. Which reminds me I have to take the mandatory driving licence test for old geezers in a month. So if a SRT comes up for sale you’ll know why. 🙄
