    So hook the ECU uplink connection to your internet feed and let the factory VPN in and reprogram. ;)

    (When a computer costs that much, doesn't it come with an "integrated lights-out" connection? :p)

    The odd thing is that the battery was always fully charged and after the clutch was replaced the car was started without issue many times. It was driven almost 200 miles. Strangely when shut off in my driveway it wouldn't start 5 minutes later and shows keys locked out.

    Dear Ferraristi,

    Gee.....I remember back-in-the-day ( not too too long ago ) you had to put the key in a slot just near the door handle and turn it to actually "lock" the door.

    ...the alarm system was the bouncer at the club or restaurant you were attending saying....move along folks...move along.

    ...ah, the good ol days :D

    You may have used up the battery, Jim. Running, it was OK, early it had enough voltage to start and run, but charge failed. Could be bad alternator or ground too. Try code, but check battery/ground first. If battery shut down BTW, the ECU has to relearn some parameters, so a 10-15 min. drive best, and use it like you normally would.

    Always start with the most simple things. Today's cars are so electronic dependent, that problem batts can cause all sorts of whacky behavior. Good luck, I'm sure you will get it back up & running fine soon.

    OK, I think I know the answer to this.

    If the battery is indeed ok, something is causing interference. The fix is to move the car to a different location, and simply press your key. So, you need to flat-bed your car a mile or more in several directions away from your house and see if the keys work before you resort to deeper surgery/fancy procedures.

    You could also try it in your garage with the doors closed, as the doors plus the lift tracks plus the house wiring and plumbing (if it's metal) might act as a bit of a Faraday cage and block out the interference. Obviously, don't leave the car running without opening the garage doors.

    Did any fancy telecommunications or AV gear or some other electronic doodad get installed recently at your place, or your neighbors'?

    Let me know if I am right. Good luck.

    Lee the battery is fully charged. It's the ecu.

    That's a long shot, but it might be a possibility. I had tons of (intermittent) problems with my garage door remote when I lived near the DEC chip plant (until Intel took it over).

    But I wouldn't expect a lot of electronic chip factories in a neighborhood where you'd park a P4/P5. ;)

    But it might be something new in the environment. Did your 'hood just get FiOS?

    On the other hand, the interference might be local -- from another key on the same keyring. Have you tried using the key by itself off the keyring, with the cell phone and any smart cards kept far away?

    One thing you can do yourself that could be the problem is to check all of the grounds. Sometimes a ground connection isn't good and while the battery is fully charged, the ground to the ECU has high resistance, and you can get a low voltage across the ECU...

    It is worth a try to trouble shoot that and make sure it isn't a grounding issue.

    Chris,

    Very, very funny. But I believe that Jim is referring to a "different dialect" of Greek that cannot be interpreted by mere mortals.

    Yes, but something could have changed...neighbor installed something, new cell phone tower/repeater, even in your own house, new electronics, etc.

    This is a known issue near a certain lighthouse in France. Exotic owners pull up to take pics, then can't get their cars restarted. Local tow truck operator takes their car a mile away, and all is well again.

    There seems to be all kinds of universal problems with the factory integrated alarms. There are a million Fchat alarm threads. I started this one:

    http://ferrarichat.com/forum/showthread.php?p=138143764#post138143764


    I think we need to solve this problem once and for all for all post 1995 Ferrari owners. With so many people involved even if someone needed to be hired to figure it out many would contribute to the cause. I bet there is someone here on fchat who has the know how to do it.

    I had a very similar problem. In my case, the ECU would not power up. I had a power junction that was not tightened after servicing, after a few hundred miles it loosened to the point that I got a no start condition. The key code light failed to go out, indicating recognition. The key code failed to recognize the keys because the ECU was not powering up at all.

    So, if any power junctions were touched during the clutch replacement, review for tightness.

    I'm going to reply here at the risk of looking real stupid. I know why some cars with transponder based keys 'lock up' and drop the programed keys. I know this happens to Ford, Chrysler and Honda. The car can't "see" more than one key at a time. I had a tech admit it to me, but the dealership wouldn't acknowledge it. Someone has two programmed keys on the same key ring, and if the moon is right and the stars align the car will "see" both keys and they are stranded. I don't even know if Ferrari uses a transponder system in their vehicles but I would imagine so.
