2008 Pontiac Solstice GXP
Partially correct. The difference between master and valet key is hardware, and is not dependent on the order the keys are learned.
incorrect. There is 0 difference between a physical valet key and a normal key other then what it can unlock. The transponder pellet inside functions identically.
This is not a debate you want to get into, I helped design transponder bypass modules made by Trilogics (XPressKit now owned by DEI) and also idata link (Compustar). I have installed 10's of thousands of remote starters and I have most main stream vehicles wiring that is used to start the vehicle memorized, location and color. These are the module names for a couple of manufacturers that handle the transponder (immobilizer) TDM (GM), SKIM (Chrysler), PATS (Ford) IA or IKT, VSA (Honda), ECU (Toyota). I am now 45 years old I retired about 4 years ago.. I worked in the automotive electronics and electrical field since I was 18 years old. before that I was active duty Army for 2 years and before that I messed around installing audio systems and other electronics into peoples cars, since I was about 14 years old.
When transponders first started to show their ugly head (1996) Ford Expedition I believe was the first, could be the first domestic vehicle, it was the first vehicle that I saw with a transponder. They started taking off in popularity in 2000. I figured out how to bypass the system in 1996 by using copper wire and a relay. wrap the wire around the handle of the key 13 times and then wrap the wire around the front of the key cylinder 7 times. This is something that is now manufactured and provides a nice black plastic box to put a key into and gets stuck up under the dashboard, it is called a 556U. And yes back then that was how the system got bypassed, we would take a key from the customer that they would not get back. The key would be up under the dashboard. The plastic piece that the key got inserted into would get popped off and under it is where the wire needed to get coiled. The 2 ends of the copper wire got connected to pins 30 and 87 on the relay. pin 85 went to a constant wire and pin 86 went to the negative activation output from the remote starter. Back then if the system could read the key it would keep the vehicles computers awake even tho the key sense and the ignitions were in the off position. This was a parasitic draw and would kill the battery. A relay MUST be used.
