It looks like that remote start system has the ability to be involved in the dome light function. It also naturally has to be involved in the passlock security wiring. It is possible that this system is involved in all of your issues and may be quite complicated. The wiring possibilities along with added relays and severed wires is extensive.

This will give you an idea of how extensively your remote start unit may be integrated into your vehicle wiring. A sample of the systems that it may be attached to/interrupt are starter, ignition, passlock, door locks, door switches, dome lights, trunk release, HVAC system, horn, lights, etc:

it all worked before with my remote I even tried a new ignition switch and key cylinder with new keys that didn't work !

I have it run start crank park lights heater radio and the over ride oh and the door locks they all lock but the driver door won't ! unlock

oh and the domes used to work with the key lock and unlock oh and my drl s stopped working !

This may be your problem The passlock system needs to see the same resistor value from the remote start hack and the key cylinder. If the key cylinder has a new value and the passlock system has learned the value set by the 7200 then the key will not start the vehicle. You need to measure the new key cylinder value and then set the dip switches on the 7200 module to be the same and then perform a passlock relearn.

We are swimming all over the place and adding new info during each post and I have no clear idea of what the history is here. You need to provide a timeline with the changes/adds/modifications and symptoms. If you can lay out the history clearly, I will try to help you. Additionally, Its beginning to sound like all of your problems are related to the remote start addition. Perhaps the forum at the manufacturer might be helpful in addition to what we can do here. There will be many people there with similar problems.


George

ive had the remote in for 6 or 7 years this just happened about two months ago

So what's the timeline of your symptoms (no start, no dome lights, no locks ...), and your attempts at repairing them (new key cylinder, ...)?


George

hey George how can I get the value I need off the 7200 ?
