Lost Car Key Replacement
in Auburn, WA

Lost your only car key — or every key you ever had? Auburn Lock & Car Keys makes new keys from scratch on-site for most vehicles. No working key required. Way cheaper than a dealer tow and 24/7 mobile across Auburn.

"All Keys Lost" Is a Specialty Service

Replacing a car key when you have a working spare is one job. Making a brand-new car key when you have nothing — no working key, no spare, nothing — is a different (and more involved) job. In the locksmith trade this is called "all keys lost" and not every shop can do it.

Auburn Lock & Car Keys is set up for it. We carry the equipment, the blanks, and the programming tools needed to make car keys from scratch on most vehicles, on-site, without towing.

Why It's More Complex Without an Existing Key

When you have a working key, programming a new one is easy: the car's computer trusts the existing key's authority to add new keys. Without that authority, we have to bypass or reset the car's security system through the OBD-II port, which involves:

  • Connecting to the vehicle's immobilizer through diagnostic equipment
  • Authenticating with manufacturer-level security access
  • Often waiting through a manufacturer-imposed security timer (10-60 minutes on some vehicles)
  • Programming new keys into a fresh authorization slot
  • Optionally deactivating any "lost" keys still floating around

Common "All Keys Lost" Situations

  • Genuinely lost the only working key — Single-key household, key disappeared, no backup
  • Both keys lost / stolen — The whole house got cleaned out, or you lost the originals years ago and never replaced them
  • Bought a used car with no working keys — Common at estate sales, repos, abandoned vehicles, online auctions, even some private sales
  • Inherited a vehicle — Family member passed, you got the car, no one knows where the keys went
  • Old vehicle that sat for years — Family vehicle in storage with the keys long forgotten
  • Vehicle from a tow yard / impound — Recovered theft cases, abandoned vehicles, etc.

What We Need From You

  • Year, make, and model of the vehicle
  • VIN — helps us pre-load programming software and the right blank. Find it on the dashboard at the windshield, on the driver's door jamb sticker, or on the title / registration
  • Proof of ownership — Title, registration, or recent bill of sale matching your photo ID. This is non-negotiable. We don't make keys for vehicles without proof of ownership.
  • The vehicle in a reasonable location — Driveway, parking lot, anywhere we can park next to it and work for an hour or two

What We Can Handle vs. What Requires a Dealer

Most vehicles — we handle on-site. Some specialty European luxury vehicles (newer Mercedes, BMW G-series, some Audi / Range Rover 2018+) still require dealer programming for all-keys-lost situations because the security systems are designed to only respond to manufacturer-authenticated tools. We'll tell you upfront based on your VIN whether we can do yours or whether a dealer tow is your only option. Call (253) 796-8550 to find out.

FAQ

Lost Car Key Replacement Questions

All-keys-lost pricing is higher than standard duplication because of the extra programming work. Basic transponder all-keys-lost: $185-$385. Remote / flip key all-keys-lost: $235-$485. Smart proximity key all-keys-lost: $325-$685. Still significantly cheaper than dealer pricing (which typically requires a tow on top).
For most vehicles, yes. Modern mobile auto locksmiths have the diagnostic equipment to access a vehicle's security system and program new keys without needing an existing one. Some high-end European vehicles (2018+ Mercedes, BMW G-series, current Range Rovers, some Audis) still require dealer programming for all-keys-lost — we'll know based on your VIN.
Typical timing: basic transponder all-keys-lost 45-90 minutes; remote key 60-120 minutes; smart proximity key 90-180 minutes including any manufacturer security delays built into the programming. Not slow work — the wait is just the car's anti-theft timer running.
Title, registration, or recent bill of sale — matching your photo ID. We need to verify you actually own the vehicle before making keys to it. This protects you from anyone trying to make keys to your car, and protects us from helping someone steal a vehicle. No proof of ownership = no keys. Period.
In most cases, yes — on request. When we program new keys, we can simultaneously deactivate any old / lost keys so they no longer start the vehicle even if found. This is important for stolen-key scenarios. We always ask before doing this since some customers want the old keys to still work if recovered.
Yes, as long as the tow yard / lot authorizes our access, you have proof of ownership, and we can park near the vehicle for the duration of the work. We've done all-keys-lost service at impound lots, tow yards, auction houses, and self-storage facilities throughout the Auburn area.
