Good afternoon, I’ve have the pass key issue. I’ve replaced the ignition. I’ve also tried soldering a resister to the ignition side of the unit still to no prevail. It’s intermittent however it doesn’t work when I need it the most. Is there anything I can do to fix this? I don’t want to rig and then it stop working again. Is there a permanent fix? This car is the Brougham model.

Good morning.

On the old pas-key system, the ignition switch has two wires that off of it. It was common for the wires to fray or break causing a no start.

The correct procedure is to replace the lock cylinder with a new one if that is the issue.
