Ford key replacement in San Diego follows the key technology: PATS transponder, remote head, or proximity fob. Dealers quote from the parts counter and usually need the vehicle on site. A mobile locksmith, when their Ford software covers the truck or car, programs at the parked vehicle.

Ford key types
| Key type | What it is | Locksmith work | Dealer notes |
|---|---|---|---|
| PATS transponder | Chip in the head, no remote | Cut blade, program chip | Service department |
| Remote head key | Chip plus lock/unlock buttons | Program immobilizer and remote separately | Parts may need to be ordered |
| Smart proximity fob | Hands-free entry, push-button start | Pair rolling-code fob | Common on later F-150, Explorer, Edge, Expedition, Escape |
PATS (Passive Anti-Theft System) has been on Fords since 1996. Wrong chip signal, the engine will not run. Cutting without programming is not enough.
Remote head keys combine chip and buttons in one unit. Both electronics pair separately.
Smart fobs on many F-150s from around 2011 onward, plus push-to-start Explorers and similar, use rolling codes at the door handles.
The F-150 is extremely common in this county, so many automotive locksmiths stock compatible blanks. Confirm your year and trim anyway.
Adding a key when you still have working keys
If you still have working keys, check the owner’s manual for this VIN before you try any add-a-key steps. Ford procedures differ by year, trim, and whether the truck uses PATS, a remote head, or a smart fob. Ask the locksmith whether two remaining keys allow add-a-key on this vehicle, or whether the job needs a programming tool.
Do not treat a sequence from the internet as a universal Ford recipe. Push-to-start smart fobs generally need shop equipment. If you are down to one key, or all keys are lost, you need a locksmith or dealer who can confirm tool coverage.
The locksmith or dealer confirms whether the new key trained. Do not use a security light as a site diagnosis.
Dealer vs locksmith
Dealer advantages: brand-new model years, warranty coverage, a few encrypted platforms with limited third-party access.
Mobile locksmith advantages: work at the truck, no tow on supported PATS and smart-fob jobs, often shorter wait than a dealer parts order.
See lost car keys: dealer vs locksmith.
All keys lost
Owner-manual add-a-key is off. The locksmith talks to the PCM through OBD, generates a new code, and pairs keys when tools cover it. Bring license, registration, and VIN. No reputable locksmith cuts without ownership checks.
F-150 SecuriCode keypad
Many F-150s and some other Fords have a five-button door keypad. It unlocks the cab without a key. Factory code is in the manual or a dealer VIN lookup. You can set a personal code once inside. It does not start the truck. Use it to get in, then have a key programmed.
Fob reprogram vs replacement
If the car still runs and the fob lost sync after a battery swap or a vehicle jump, key fob programming may be enough. Check the coin cell first: key fob troubleshooting.

The locksmith quotes after key type and whether any programmed keys remain. Swift Key does not publish ranges.
Can I program a Ford key myself?
Follow the owner’s manual for this year and VIN. Ask the locksmith whether remaining keys allow add-a-key, or whether a programming tool is required. Smart fobs generally need a tool. This site does not publish a timed recipe.
Can a locksmith replace an F-150 key on site?
Usually, for PATS and common smart fobs. All-keys-lost is still an OBD job at the truck when tools cover it.
