Key Duplication Service in San Francisco, CA – FAQs

  • How Long Does a Key Duplication Service Take?

    Most standard keys are duplicated under 10 minutes, right while you wait. For high-security or specialty keys, the process may take a bit longer, especially if we need to verify authorization or program electronic components. But as your trusted Key Duplication Service in San Francisco, CA, we prioritize speed without sacrificing precision. Just bring your original key, and we’ll get you a working duplicate fast.

  • Is a Key Duplication Service Safe for High-Security Locks?

    Absolutely, when you work with a licensed professional like A-A Lock & Alarm Inc., High-security keys (like Medeco, Mul-T-Lock, or Schlage Primus) often require authorization, but we follow strict protocols to ensure every duplicate is legal, secure, and fully functional. Our Key Duplication Service in San Francisco, CA, never bypasses security features. Instead, we preserve them, so your lock system stays just as safe as the day it was installed.

  • Does a Key Duplication Service Work for Worn or Damaged Keys?

    Yes, but it depends on the condition. If your key is too worn, bent, or broken, copying it directly might produce a duplicate that doesn’t work well. In those cases, we use specialized tools to decode your lock and cut a fresh key from the original specs, not the damaged copy. That’s part of why locals trust us as their go-to Key Duplication Service in San Francisco, CA: we don’t just copy keys, we solve the real problem behind the request.

  • Can a Key Duplication Service Duplicate Electronic or Smart Keys?

    We can duplicate many types of electronic and transponder keys, but they require more than cutting. Most modern car and smart home keys need programming as well as physical duplication. At A-A Lock & Alarm Inc., we handle both steps on-site using dealer-level equipment. So whether it’s a transponder key, key fob, or smart entry device, our Key Duplication Service in San Francisco, CA has you covered with full functionality and security.
