Question 1

What is the cheapest way to handle all-keys-lost on my 2006 Fusion?

Accepted Answer

Call a mobile locksmith before you call the dealer. An all-keys-lost situation at a Ford dealer typically means a tow to get there, then OEM fob costs plus programming labor, and the total can climb fast before you factor in wait time. A mobile locksmith handles the same job on-site: decode the lock or use the VIN for the key cut, erase the old stored keys, program at least two new remote head keys in a single session, and test everything before leaving. You get a price on the phone and that's the price you pay. No tow bill, no service bay markup.

One thing to know about the 2006 specifically: Ford's immobilizer requires a minimum of two keys programmed during an all-keys-lost reset. You can't just do one and call it done. Plan for two keys from the start.

Question 2

Can you delete a lost or stolen key from my Fusion so it can't start the car anymore?

Accepted Answer

Yes, but the way it works is a full wipe, not a selective delete. The immobilizer doesn't let you pull one key out of the list while keeping the rest. The reset clears everything, and then you re-register only the keys you authorize right then in that session.

The stolen fob's transponder is dead after that. It will not start the engine. The physical blade is a different story: if someone has a cut key, that can still open the door lock mechanically. It just won't get the car running. If you've had keys stolen, a police report for your records and a full reprogram done same day is the right move.

Question 3

Does my 2006 Fusion remote head key have a hidden emergency blade inside it?

Accepted Answer

No, not in the way some newer Ford fobs do. The 2006 Fusion uses a remote head key, meaning the blade is fixed and permanently attached, not a folding or hidden insert. The key blade sticks out of the fob body as one integrated piece. You use that same blade for the door lock and the ignition. There's no release button, no slide-out blade to go hunting for.

If the fob battery dies, you still have the blade in hand and can physically turn the ignition. The remote functions just won't work until you get a fresh CR2032 in there.

Question 4

I bought a replacement fob online for my 2006 Fusion. Can I program it myself at home?

Accepted Answer

There is a self-programming sequence that works on some older Ford remote head keys if you already have a working programmed key in hand. The process involves a specific series of ignition and door lock steps done in a timed sequence. A lot of Fusion owners have found it on forums and tried it.

Here's where it gets complicated: the remote buttons can sometimes be enrolled that way for the keyless entry functions, but the transponder chip inside the fob still needs to be properly paired to the immobilizer. If the chip isn't registered, the fob will lock and unlock your doors just fine and then not start the car. That's the part that trips people up. They think the programming worked because the locks responded, then they're stranded in a parking lot.

If you're not certain whether the fob you bought includes the right transponder and whether it was registered correctly, have a locksmith verify both before you rely on it.

Question 5

My Fusion starts fine but the remote buttons stopped working. Is the fob bad or is something wrong with the car?

Accepted Answer

Start with the CR2032. A remote head key on this car can have enough juice left in the battery to start the engine via the transponder but not enough output to fire the radio frequency signal for lock and unlock. It's a common split failure and it almost always turns out to be the battery.

If a fresh CR2032 doesn't fix it, the next thing to check is whether you're within reasonable range when you try the buttons. These fobs don't have extreme range. Then look at whether both buttons are dead or just one. A single dead button is usually a worn contact pad inside the fob. Both buttons dead after a battery swap points toward a failed receiver module on the car side or a fob that needs to be re-enrolled. That's a quick diagnostic, not a major job.
