Smart / Proximity Key Programming in Union City, CA.

If you need smart / proximity key programming in Union City, this is how One & Only Locksmith handles it.

Proximity (smart) keys unlock and start the car without leaving your pocket. The fob talks to the vehicle's smart-key module over low-frequency and UHF radio, and the car only responds to fobs that have been enrolled in that module. Smart key programming is the enrollment of a new or replacement fob, plus cutting the emergency blade hidden inside it so you can still open the door when a battery dies.

The technician comes to your address in Union City, in the East Bay. The dispatch line at (888) 492-0666 is answered around the clock, and the dispatcher confirms the details and an ETA before anyone is sent.

• Exact fob matching by year, make, model, trim and the FCC ID or part number on your existing fob (frequency and feature set vary even within one model year)
• Enrollment of the fob into the smart-key module through the OBD port using manufacturer-specific software
• Emergency blade cut to the vehicle's key code so the fob opens the driver's door mechanically
• Remote function test: lock, unlock, trunk or hatch, panic, and remote start or power doors where the fob supports them
• Push-button start test from inside the cabin and, where the car allows it, a dead-fob start with the fob held against the button
• Confirmation of how many fobs the vehicle now has stored

• Photo ID plus registration or insurance card
• Year, make, model, trim and VIN
• A photo of the back of a working fob showing the FCC ID and part number, if you have one
• All working fobs; some enrollment procedures need every fob present or re-enroll them in one session
• Whether the car has features tied to the fob such as remote start, power liftgate, power sliding doors or a driver memory profile
• A car with a healthy 12V battery, parked where we can reach the OBD port

Typically 30-60 minutes to add a smart key next to a working one. All-keys-lost enrollment on some makes includes a built-in security wait and runs 60-120 minutes, and certain European models need an extended session or module-level work that we confirm by phone.

• Late-model premium makes are often dealer-only: most Mercedes with FBS4 (roughly 2015 and newer), many 2020-and-newer BMW, Audi, Porsche and Range Rover models, and some current Volvo and Jaguar systems. We tell you before dispatch
• Many 2018-and-newer Chrysler, Dodge, Jeep and Ram vehicles sit behind a security gateway that needs authorization before the smart-key module can be reached
• Toyota and Lexus models with the newest smart-key generations may require specific tool support or a longer reset; we confirm by year
• A fob with the wrong FCC ID will program and then fail to work, or will not program at all; this is why we match the part before we arrive
• A dead 12V battery or a car that has been in storage can stop the module from responding during enrollment
• Tesla uses key cards and phone keys paired from the touchscreen with an existing card rather than a programmed fob

The quote depends on the make and year (premium European smart keys cost more and take longer than mainstream Japanese and domestic ones), on whether you still have a working fob or need all-keys-lost enrollment, on OEM versus quality aftermarket fob, on how many fobs you want enrolled, and on the time of day. You see the price in writing before programming begins.

The dispatcher gives you a range on the phone, and the technician confirms a written quote before any work starts.

Payment is by Cash, Credit Card, Debit Card, Apple Pay and Google Pay, and you receive an itemized receipt listing what was done.

• Toyota and Lexus smart keys (board types by generation; emergency blades TOY48 and TOY51)
• Honda and Acura smart keys with the HON66 emergency blade
• Nissan and Infiniti Intelligent Keys (NSN14 blade)
• Hyundai and Kia smart keys (HY22, KIA7, KIA9 and later blades)
• Ford and Lincoln Intelligent Access fobs, GM keyless fobs, Mazda advanced keyless fobs, Subaru smart keys
• VW and Audi keyless fobs (HU66 and HU162T blades), BMW Comfort Access and Mercedes Keyless-Go where the model year allows on-site programming
