Key types by year, side by side
Both vehicles changed key technology over their runs, so the right blank, chip, and programmer depend entirely on your model year. Here is what each one uses:
Ford F-250 Super Duty
H75 blade with 80-bit PATS transponder chip.
H92 blade, 4D63 80-bit PATS chip.

Which is simpler or quicker to key?
Neither the Ford F-250 Super Duty nor the Ford F-350 typically needs a dealer for routine key work. Both are mobile, on-site jobs: a spare comes from a working key in a single visit, and a lost-all-keys situation means reading the immobilizer PIN through the OBD-II port before enrolling the new key.
The quirk that trips people up on each
- 80-bit cut precision. The F-250's H75 and H92 80-bit blades need exact cutting, and a loose aftermarket cut can wear the cylinder or break off in the field.
- 80-bit high-security cuts. The F-350's HU101 high-security blade needs precise cutting; a sloppy aftermarket cut binds in the cylinder and can break off.
How a key job runs on either one
The path works the same way on both. The simplest job on either vehicle is a planned spare made while you still have a working key, because that key acts as the authentication seed and the work is short. A lost-all-keys situation takes more steps on either one, since the programmer has to read the immobilizer PIN before it can enroll a new key. We confirm the exact part by VIN before we dispatch, so the right blank, chip, and programmer are on the truck when we arrive.

Frequently asked: Ford F-250 Super Duty vs Ford F-350 keys
Is the Ford F-250 Super Duty or the Ford F-350 simpler to make a key for?
They are comparable. A spare made from a working key is the simplest path on either vehicle; a lost-all-keys situation takes more steps because we read the immobilizer PIN first. We confirm the exact path by VIN before dispatching.
Can you make a key for both on-site in Statesboro?
Yes. Both the Ford F-250 Super Duty and the Ford F-350 are handled by our mobile unit at your location for the large majority of year ranges. Any exception that needs dealer coordination is flagged on the phone when we confirm your VIN, so the work is set up correctly before we arrive.
Do I need the original key to get a replacement?
No. With a working key we make a spare in a single visit because the original acts as the authentication seed. With no key at all, we read the immobilizer PIN and build a key from your VIN. Both vehicles support both paths.
