My F-350/F450 Car Key Is Not Detected
A major cause of a “key not detected” message is interference from other devices. Perhaps you have another key with you which uses the same technology as your key.
The foreign key may be blocking your key’s signal. Other devices like a smart phone or something with a transmitter can also cause the same problem.
Try moving the items as far away from each other as possible, then start your car again.
Sometimes, there might be no device that could’ve caused the interference around you. In such cases, it is likely as a result of a damaged transmitter in your key fob.
Your key battery may be displaced in your fob due to agitation. This mostly affects fobs with no extra cover on their batteries.
If the problem persists, have your key and the ignition checked by a professional.

What to Do When Key Is Stuck in the Ignition?
A truck with automatic transmission will lock the key if you don’t set the gear lever to Park. This keeps your truck from taking a stroll while you’re away.
If that’s the case with you, make sure you adjust your gear lever and pull your key out.
A rusted or worn key is another likely culprit. Lubricate the ignition and pull your key out or call your locksmith to get it out if lubrication doesn’t work.
Have him/her cut or program you a new key as soon as possible.
If the problem is from the ignition, the ignition should be changed.
However, it is most likely due to the key or a locked steering wheel. Turn your steering left and right and gently pull your key till it’s out.

How to Find Key Codes for Lost Keys
You can get your key code from your owner’s manual.
A Ford dealership or registered locksmith can also get you your key code by providing your Vehicle Identification Number (VIN).
However, your truck’s ignition may have been changed in the past for some reason. In that case, the current key code of your current ignition cylinder cannot be gotten from your VIN.
The VIN would only provide the code of the original ignition cylinder that came with the truck.
The locksmith who fixed the new ignition cylinder should have the code. Sometimes they may not.
Not to worry, the locksmiths can always find your key code no matter the circumstance.
You just have to show your documents to prove that you’re the owner of the truck.

What to Do If the Key Won’t Turn?
This happens when your car battery is too weak to engage the ignition cylinder to function properly. The solution is to recharge your car battery.
After charging your battery, the key and ignition should function properly.
It could be that your ignition lock cylinder is damaged and needs to be replaced. Before that happens, you may have to provide your VIN to the locksmith depending on the policy in your location.
A locked steering wheel can also prevent your key from turning. Likewise, your key won’t turn if you use an automatic transmission and it is not in Park.
My Key Won’t Go in the Ignition
The problem is probably with your key; it might be deformed due to extreme heat or cold. It may simply be bent because of rough handling, and would need to be replaced.
Straightening your key with a hammer can be a temporary solution if you use a non-transponder key.
A broken key should not even be inserted into the ignition switch in the first place. It should be discarded at once or kept for reference purposes when getting a replacement.
If accumulated particles on your key over time is the source of the problem, clean your key thoroughly with alcohol. Avoid habits that attract dirt to your key.
You may have accidentally enabled the anti-theft feature of your car. Anti-theft system immobilizes your engine and may cause your key hole to be inaccessible.
Pressing the panic button on your key fob should disable the anti-theft feature momentarily.
What to Do If Keys Are Locked Inside a Ford F-350/F450?
Although modern trucks are equipped with features that prevent owners from locking their keys in the car, we assume you use an earlier model for the sake of this question.
The police or fire service can get it open for free. However, something tells us you do not want that option.
Call your locksmith to the spot; he/she would charge quite a sum (say $50). It is still cheaper compared to the towing costs you’ll pay if you were to take the car to the dealer.
You might also be able to use a car door wedge and a wire hanger to unlock your truck and get your key out.
Ford F-350/F450 MyKey Explained
A new F-350/F-450 comes with two keys. You can program your truck to distinguish between the two keys the same way it’d recognize a new replacement key.
MyKey limits certain features on the truck. One of both keys can be inserted and programmed to be a MyKey.
You can set a maximum speed limit of say 80 MPH, or choose not to set a speed limit at all.
Your truck can be configured to chime when the speed gets to 75, 90, or 105 MPH. You can also set a limit for the radio volume.
After configuring the MyKey settings to your taste, pull out your key. It’ll function according to the set limits whenever you start the truck with it.
When you start the truck with a MyKey, you have to buckle up your seatbelts to unmute the radio. If you try going past the maximum speed, the car simply maintains the set speed.
The “low fuel” warning also appears sooner when using a MyKey. That way, the teenager driving has more time to refuel.
The other key would now act as the administrative key. Only the administrative key can be used to clear the MyKey settings.
