Frequently Asked Questions

  • A licensed automotive locksmith can program most key fobs on-site — no dealership visit needed. National Lock & Key uses professional-grade equipment to program replacement and spare fobs for most vehicle makes and models, including Toyota, Honda, Ford, Chevy, Lexus, Nissan, Hyundai, Kia, Jaguar, Land Rover, and more. We come to your home, office, or roadside location anywhere in Northern Virginia and Washington D.C.

  • Both are key fobs, but they work differently. A standard fob requires you to press a button to lock and unlock your vehicle. A smart key (also called a proximity key) detects your presence automatically — your car unlocks when you touch the handle without pressing anything. National Lock & Key programs both types for most vehicle makes and models.

  • In most cases, key fob programming takes 45 to 60 minutes on-site. The time depends on the vehicle make, model, and year, and whether we're programming a new fob from scratch or syncing an additional spare. We carry OEM and aftermarket fob options, so most jobs are completed in a single visit.

  • Yes — same-day appointments are available based on technician availability. We serve Fairfax, Arlington, Alexandria, McLean, Reston, Herndon, Chantilly, Centreville, Sterling, Great Falls, and surrounding areas. Call (571) 449-6495 to check availability for your location.
