2011 Ford Transit Connect (FTC) with possible Passive Anti-Theft System (PATS) no-start after battery drained and some rain got in. If two unique keys are needed to reprogram but we only have one, should we completely avoid resetting the Instrument Cluster (IC) or the Powertrain Control Module (PCM), or is there some way to back-up the lost 2nd key info from the IC or PCM to re-write it when resetting both the IC and PCM with the remaining 1st key?
