What is key fob programming?
Modern keys aren’t just cut metal — they carry an electronic chip or remote that must be programmed to your vehicle’s immobilizer before the car will recognize them. Programming pairs the fob’s unique code with the vehicle’s security system, allowing it to unlock the doors and start the engine. Without it, even a perfectly cut key won’t start the car.
Types of keys we program
- Remote fobs — lock/unlock remotes, including remote-head keys
- Transponder/chip keys — keys with an immobilizer chip
- Smart keys / push-to-start — proximity keys for keyless ignition
When do you need FOB programming?
- Adding a spare fob so you’re never stranded
- Replacing a lost, broken, or water-damaged fob
- A fob that stopped working after a battery change or repair
- Buying a used car that came with only one key (or none)
- All keys lost — a new key must be originated and programmed
Mobile locksmith vs. dealer for fob programming
A mobile locksmith programs your fob at your location, usually faster and without the dealership markup or a tow. The dealer is mainly worth it for brand-new models whose key software isn’t yet available outside the dealer network. See the full comparison in Dealer vs. Locksmith for Car Keys.

What Others Say About Us & Our Services
The website was easy to navigate and I found the service I needed and was able to book the perfect time between work. The technician messaged me a day early letting me know that he would be in the area and gave me the option to get it taken care of early but unfortunately I was working. If I hadn't been that would have been amazing to get it done ahead of time. He was on time and very pleasant. Worked quickly and got my problem taken care of. It was such a better experience than sitting in a waiting room with strangers or having to take an Uber back and forth to avoid such situation. I'm already recommending them to my friends because of how easy it was. Why go to a shop to get your car fixed at the shop can just come to you?
