Standard Motor ProductsInc. - Lock Cylinder (US-23LT)

This Lock Cylinder is like a Chinese puzzle. Once you figure it out it is simple but you have to do it right.#1. The lock cylinder fits into the ignition cylinder US85.#2 But the lock does not fit all the way in the cylinder.#3. Here is the trick. There is a pin on the rim of the ignition cylinder. Insert the paper clip down through the tiny hole in the top of the lock cylinder when you move the key to center it over the pin.#4. Move left or counterclockwise the key past the pin.#5. Now force the lock down in the clylinder making sure the bottom tab is lined up with the bottom recess of the cylinder.#6. Then move the key clockwise and you are all set.#7. If you installed it right the key will spring back from the far right postion. Just like it should when starting a car or truck.#8. If you didn't do it right the key will just act dead instead of springing back. I know because I did it wrong several times. I wrongly set the lock with the key far right instead of left past the pin.#9 This seems to be an old Ford generic key lock set up. I installed mine in a 1995 Ford L8000 which is a semi truck. I suspect a lot of old Fords of various models had the same set up.#10 It may take a while but don't give up. It was aggravating at first because I could not remove the key. You can only remove the key once it is set in the cylinder. But keep in mind you can set it wrong and still remove the key. It is only set right when the key springs back as if you were starting the vehicle.#11. Good luck.

Perfect fit 👍

Not much else to say, other than it fit my '72 F100 perfectly. Came with 2 keys.

Worked great and was easy to install

Fit perfect

Put it in my 71 F100. Ignore the instructions and watch YouTube videos. It is incredibly frustrating to get it in and out, until you figure out the pin hole/twist combination. Then it falls right into place.

This is advertised as fitting 66 Mustang but it doesnt

Good product
