Mobile Ford Key Service
Cut and Programmed at Your Truck

PATS is short for Passive Anti-Theft System, Ford's transponder-based immobilizer. It launched on the 1999 F-150 and rolled out across the rest of the Ford lineup over the next few model years. If your Ford is a 1999 or newer, the answer is almost certainly yes. The system reads the chip inside the key on insertion or presentation, and if it doesn't recognize that chip the fuel pump and starter never engage. A blank cut to the right pattern but without a programmed chip will turn in the ignition fine, but the engine won't crank. We program PATS keys mobile using OBD tools, anywhere in San Diego County, no dealer slot to book.

Yes. The F-150 is the single highest-volume Ford we service across San Diego County. Broken out by era: 1999 through 2014 trucks get the full job at your location using the correct transponder chip and OBD programming. 2015 and newer F-150s on the HU101 keyway with the 128-bit ID46 chip get the high-security blade cut at the truck and the flip fob or smart key programmed through the OBD port. All-keys-lost on any F-150 generation requires a PIN pulled from the instrument cluster, and our tools handle that automatically.

Ford flip keys arrived in 2015 starting with the F-150. The cut blade folds into the fob body and springs out when you push a button, but you still have to insert it into the ignition cylinder to start the vehicle. Smart keys came three years later in 2018, aimed at push-to-start trucks. They carry a small emergency blade inside the shell, but the blade only handles manual door unlock if the proximity system isn't responding, the truck reads the smart key wirelessly and the start button does the rest. We program both flavors at your location.

Almost certainly not. For most Fords from 1999 through 2023, all-keys-lost is a job we run at your location, not at the dealer. Our OBD tools pull a security PIN from the instrument cluster or PCM, then program new keys without erasing memory until at least two new keys are ready. There's a Ford-specific quirk worth knowing: the system requires a minimum of two new programmed keys to finalize the all-keys-lost workflow. For the 2021 F-150 Lightning and other newer EV Fords, we verify tool compatibility on the phone first before dispatching anywhere in San Diego County.

Start with the fob battery, that's by far the most common cause. Most Ford fobs use a CR2032, and the dashboard throws a key battery low warning before the battery dies all the way. If a fresh battery doesn't restore detection, move to the BCM sync question. The fob can fall out of sync after its battery runs flat or after the truck's main battery gets disconnected for service. On pre-2018 Fords the workaround is a vehicle battery disconnect for 15 to 30 minutes. On 2018 and newer trucks the BCM changed and the resync needs an OBD tool. We handle either path at your truck.

Every push-to-start Ford ships with a backup method for exactly this. The location varies by model, though, so check yours: Explorer drivers place the fob in the small pocket at the front of the center console. Focus owners (2015 and newer) lift the center console armrest, pull out the storage tray, and lay the fob on the symbol inside. Edge owners (2020 and newer) use the shelf at the bottom of the center console. On older nameplates like Fiesta and C-Max, hold the fob against the steering column right where the old ignition cylinder used to live. In every case the next steps are the same: brake firmly, push the start button. The truck reads the passive transponder chip directly, no fob battery required.

For most 2000 through 2018 Fords, yes, as long as the FCC ID on the new key matches what your truck expects. Quick reference: the CWTWB1U331 platform covers a broad range of F-Series, Explorer, Fusion, and Escape remote head keys through 2016. The N5F-A08TAA covers 2015 to 2016 flip keys on F-150, Explorer, and Fusion. For 2018 and newer smart keys running the M3N-A2C93142300 FCC, compatibility tightens up significantly and we strongly recommend checking before any purchase. Send us the year, model, and the FCC ID printed on your existing fob, and we'll tell you whether the one you bought will actually work before you spend money on it.
