What do homeowners ask about Key Fobs?
Why do key fobs need programming?
Modern fobs use rolling-code encryption paired with your car's immobilizer. When you replace or add a fob, the car's computer needs to learn the new fob's ID. Without programming, a factory-fresh fob is just plastic, it won't start the car or unlock the doors.
Can I program a fob myself?
On some older vehicles (pre-2010 Ford, GM, Chrysler), yes, there's a sequence of ignition turns and button presses in the owner's manual. On everything newer and on luxury makes, no, the programming requires a tool that talks to the car over OBD. That's what we carry.
Can you program a fob I bought on Amazon or eBay?
Sometimes. If the fob is a genuine OEM or a high-quality aftermarket blank with the right chip, yes. If it's a knockoff with a cloned chip, no, most won't pair. We can usually tell when we see it. If it won't pair, we provide a known-good blank and credit your time.
My remote start stopped working. Can you fix it?
If it's factory remote start, usually yes, it's a programming issue or a fob battery. Aftermarket remote start (Viper, Compustar) we diagnose and point you to the right fix; we don't currently install new aftermarket systems.
How much does key fob programming cost in San Diego?
Reprogramming an existing fob that lost sync runs $75 to $125. Cutting and programming a brand-new fob runs $150 to $300 for most domestic and Japanese makes. Luxury and European fobs (BMW, Mercedes, Audi) run $250 to $400. We quote a firm number before we start. Most jobs run 20 to 45 minutes.
Where can I get a key fob programmed near me in San Diego?
A dealer and a mobile locksmith are the two real options. Dealers charge more and require you to bring the car in, which can mean a tow if you have no working keys. We come to your location anywhere in San Diego County, usually same day, and carry programming tools for most makes. Call us and we'll confirm your vehicle before we dispatch.
Can you program a fob for any car make?
We cover the vast majority of domestic and import makes, including Toyota, Honda, Ford, GM, Nissan, Hyundai, Kia, Subaru, Mazda, VW, BMW, Mercedes, and Audi. A small number of newer luxury models require dealer-only programming due to locked security modules. We tell you upfront if that's the case so you don't waste a service call.

Locked keys in the car at Target parking lot on a Sunday afternoon. Called and the tech was there in 25 minutes. Used some kind of inflatable wedge and a rod, no damage to the door. Paid what they quoted, no surprises.
Just bought our first house and wanted all the locks rekeyed. Four doors, keyed alike, done in under an hour. The tech explained everything and even showed us how a rekey works. Way cheaper than replacing all the locks like we thought.
My late father's safe had been sitting locked for ten years, we had no combination. Swift Key opened it non-destructively, then helped me change the combo so I could actually use it. Took about 90 minutes. Professional and careful with the safe.
