What We Do

Modern key fobs use Radio Frequency Identification (RFID) and rolling-code technology to wirelessly communicate with your vehicle’s Body Control Module (BCM). S.A. Locksmith & Security provides complete key fob replacement, programming, cloning, and battery replacement for all fob types: standard remote fobs, remote-head keys (key + remote combined), smart proximity fobs (push-to-start), and flip key remotes. We carry OEM and quality aftermarket fobs for Ford, Chevrolet, GMC, Toyota, Honda, Nissan, Hyundai, Kia, BMW, Mercedes-Benz, Audi, Volkswagen, Chrysler, Dodge, Jeep, Ram, Lexus, Acura, Infiniti, Subaru, Mazda, Mitsubishi, and more. Our programming tools include Autel IM608 Pro, VVDI Key Tool Max, SmartPro, and AutoProPAD.

Frequently Asked Questions

How much does key fob replacement cost?

Key fob replacement typically costs $150-$450 depending on the vehicle and fob type. Push-to-start smart fobs cost more than basic remotes. Call (210) 348-3677 for your quote.

Can you program a key fob without the dealer?

Yes. We have professional diagnostic tools (Autel, VVDI, SmartPro) that perform dealer-level fob programming for all makes and models.

Do you carry key fobs in stock?

Yes. Our mobile units carry OEM and quality aftermarket fobs for most popular vehicles. For rare or luxury fobs, we can source and program them same-day in most cases.

My key fob buttons stopped working. Do I need a new one?

Not always. It could be a dead battery ($5-$15 fix), worn button contacts, or a programming issue. We diagnose the problem before recommending replacement.

Can you program a key fob I bought online?

In many cases, yes. However, some aftermarket fobs may not be compatible. Call us first to verify before purchasing.
