Key issue(s)

[Sleeper4SHO]

Forgive me if there's a thread on this already. I'm at work trying to use the search function on my phone and its fighting me damn it!

2 different key issues maybe related...

Key #1 is recognized by the car and allows me to start it. Problem is as of yesterday the lock/unlock/trunk functions won't work on the key. Worked fine when I left work Tuesday AM, 15 mins later when I got home none of the buttons work!?! Smdh

Key #2 is not recognized by the car so I replaced the battery. The lock/unlock/trunk functions all work on the key but its still not recognized by the car. "No key detected" when I try to start it

Damn electronics!

TRY checking the fuse box compartment under the steering wheel to the left,you may have to remove a trim panel to access it,check #9,10,or 18,fuse,,do you hear anything when in accessory mode??

I'm in the same boat, i've replaced batteries twice now. Still finicky, car will start then "no key detected" error pops up at least once to twice a week... Thought about taking to the dealer, but i forsee them saying "buy a new key-fob or change the battery...DUH"

when i first got my SHO (its a 2011 non-pp) i could just hop in the car with the key in my pocket and start it, no problems. Now lately if the key is not in the cup holder, it doesn't want to start and gives me the "No Key Detected"

this recently started happening to me. I bought the car used under a year ago so i just assume its the battery. Ive some tsb problems but they never show themselves again like the sticky speedo. one day did it never again.

Guys I've had issues with the key fob, in one instance it lost complete reprogramming and I couldn't use it to start the car. I went on the web and found another MKS with the same issue and they unplugged the battery for 20-30 minutes which cleared out all issues. Tried it as well with success, just a free solution if it works.

I'll have to give it a whirl! My biggest gripe with it lately has either been 1 of 2 things

1. Hop in car, key in pocket, start car, 5 seconds after car starts... "No Key Detected"

2. Go to hit trunk button by license plate.... nothing. Stretch my arm out with key in hand close to the right tail light/gas tank door.... trunk pops open when i hit the button by the licensee plate.... I also have the same results when i hit the trunk button on my Key Fob.

Try to see if the other key fob acts the same way,sometimes a low level battery will cause the key fob to work intermitenly,only if our key fob had a led light built in showing the status of the battery life would be great.

Hmm, I'll have to give this a try. 

Last weekend neither of my keys would work, couldn't even start the car with the keys in the "safety position".  A trip into the dealer after I was finally able to get the car started and they re-programmed both keys and replaced the batteries.  I was told, "hopefully that fixes your problem, and we don't see you again".

Well, fast forward to this past weekend and again, the same thing one key was completely dead, couldn't start the car with key in the console.

I did have to replace the car battery a few weeks back, as it went completely dead randomly.  I wonder in the module didn't go to sleep or wake up properly when the car battery died and this is causing it? 

It also seems to be related to temperature, and the temperature in which the remote is subjected to.  Both instances when this happened the remotes were subjected to temps @ or below 40°F for hours.  In the last case I ran inside to the good remote (inside the warm house), and it worked fine, but not the colder one.

Regardless my comfort feeling is not too high with my local dealer (which is in Metro-Detroit).

I picked my SHO up from Tom Holzer Ford in Farmington Hills. They were pretty solid with customer service, might not hurt to give them a call.

Since then I've moved to Cincinnati and the dealer i go to thats right next to my work is.... meh, they're alright

That's precisely who the car went to when this whole ordeal happened. I work a mile up the road for a major auto supplier.  I had to give them direction in their own system to find TSB's similar to my issue.

First time there they were overly assertive to fix my windshield (which is fine), rather than change my oil like I requested.  This time I got the greenhorn writer that had no authority or clue what was going on. 

Albeit my problem is intermittent, and out of warranty.  But I know the Ford tech hotline system well enough, I call should have been made to them, and I guarantee this was never done.  I've seen the tech hotline solve issues like this in literally seconds.

Its kind of upsetting to know how out of touch these supposedly Ford techs are regarding our SHO,there more familiar and have more knowledge with pickup trucks so it seems.

Had my key not work the other day after letting it sit in the cold garage for a few hours.

There goes that myth about putting batteries in the freezer...lol

Keys (like reptiles) seek warm, cozy places like palms or pockets

I had a similar problem last month, then both keys would not be recognized by the car. Took the car to the dealer, they replaced the module and both fobs under Ford ESP. I also had a PTU replaced, a trans position sensor, and front brake job while there. Total cost was $296 out of pocket.
