Sorry to revive this thread, but I've been having persistent issues with my Ultimate Key. I received mine several months ago. Had the key cut and programmed the key myself without issue. The key seemed to work fine initially, but then became very unreliable. Ignition has always worked, but the button functions became more and more sporadic. I naturally thought it was simply a dying battery. I replaced the battery which didn't help. Contacted Andrew who, after trying to track down other causes, sent me a new circuit board. Reprogrammed the key successfully (i.e. got all the requisite 'honks') but still nothing. As a test, I switched out the board from one of my OEM keys into the Ultimate Key and it worked fine.
Next step is Andrew will be sending me an OEM Ford circuit board.
Now if this doesn't work, what else can we do here? Ben, did you ever get yours figured out?
One suggested problem is that the car has too many keys programmed. I'm the second owner, but I'm pretty sure the first didn't program any other keys. Besides, I was able to successfully complete the programming sequence and the key did work (albeit intermittently) at first.
Clinton, do you know how many keys can be programmed before you need to get the car 'reset'? I assume this process is a simple affair for any dealer? If I need to take my car in for this, last thing I need is for some young tech scratching his head and bricking my ECU trying to figure out this process.
