Hey, I've been having excellent luck unlocking the CAS3 keys. Unfortunately the HUF 315Mhz F-series key is giving me problems. It completes the job just fine and unlocks the key. The problem is that remote and comfort access are not working on the unlocked keys. They are only working when held to the column. I figured this was just a bad key, so I tested with additional keys and cars. I have now tested with 3 different cars and half a dozen OEM keys, all with the same issue.
I tested the RF frequency, and all of the unlocked keys are in the 313mhz range, while the original working keys are in the 314-315mhz range. Is there an issue with the key firmware?
