Retail Preventive

Duplicate Keys & Spare Keys

A spare key is the best insurance against an all-keys-lost situation. We duplicate transponder keys, remote head keys, and proximity fobs with full programming to your vehicle's immobilizer system.

Benefits

  • Significantly lower cost than all-keys-lost service
  • Factory-quality key blanks and professional cutting
  • Transponder and remote programming included
  • Peace of mind for families sharing one vehicle

Common Situations

  • Only one key came with the vehicle at purchase
  • Spouse or teen driver needs their own key
  • Work key and personal key separation
  • Proactive backup before travel or relocation
Retail Programming

Key Programming

Modern vehicle keys require programming to communicate with your immobilizer and control modules. Whether you need a replacement key, a spare, or reprogramming after module work, we handle transponder pairing, remote functions, and immobilizer synchronization on-site.

Benefits

  • Transponder and remote programming in one visit
  • Compatible with OEM and quality aftermarket keys and fobs
  • Re-sync existing keys after battery or module changes
  • Mobile programming at your location

Common Situations

  • Replacement key or fob needs programming
  • Vehicle not detecting key or remote functions stopped working
  • After BCM, ECM, or receiver module replacement
  • Adding a key to a vehicle with existing keys
Retail Repair

Ignition Repair & Replacement

Worn ignition cylinders, stuck keys, and damaged ignition switches prevent starting and can leave you stranded. We repair and replace ignition systems and re-sync keys to the new cylinder.

Benefits

  • Ignition cylinder repair and full replacement
  • Key extraction from broken or stuck ignitions
  • Re-keying to work with existing keys when possible
  • Mobile service reduces downtime

Common Situations

  • Key won't turn in ignition cylinder
  • Key broken off inside ignition
  • Ignition feels loose or wobbly
  • Vehicle won't crank despite good battery
Advanced Commercial

ECM Programming

The Engine Control Module (ECM) manages engine operation and communicates with the immobilizer system. ECM replacement or reflash requires specialized programming to match your vehicle's VIN, security keys, and configuration data.

Benefits

  • VIN-matched ECM programming and configuration
  • Immobilizer pairing after ECM replacement
  • Support for repair shops and collision facilities
  • Dealer-level diagnostic equipment on-site or at your shop

Common Situations

  • ECM replaced after engine repair or failure
  • Vehicle won't start after ECM swap
  • Immobilizer light on after control module work
  • Used ECM needs VIN programming
Advanced Commercial

BCM Programming

The Body Control Module (BCM) manages lighting, locks, windows, and keyless entry systems. BCM replacement requires configuration programming and often immobilizer re-pairing to restore full vehicle functionality.

Benefits

  • BCM configuration and option programming
  • Keyless entry and remote function restoration
  • Immobilizer and security system re-synchronization
  • Ideal for body shops and electrical repair facilities

Common Situations

  • BCM replaced after collision or water damage
  • Remote locks and key fob stopped working after repair
  • Security light active after BCM swap
  • Feature configuration needed on replacement module
Advanced Commercial

Module Cloning

Module cloning transfers configuration and security data from a failed module to a replacement unit. This can reduce programming time and restore vehicle operation faster than full re-programming in compatible applications.

Benefits

  • Faster turnaround for module replacement scenarios
  • Preserves existing key and immobilizer pairings when possible
  • Reduces need for additional key programming steps
  • Valuable for shops managing repair timelines

Common Situations

  • Failed immobilizer or security module needs replacement
  • Original module partially functional for data read
  • Repair facility needs expedited vehicle return
  • Module replacement during insurance claim repair
Advanced Diagnostics

Immobilizer Diagnostics

The immobilizer system prevents unauthorized starting by requiring a programmed key transponder signal. When this system faults, your engine cranks but won't start—or won't crank at all. We diagnose and resolve immobilizer issues.

Benefits

  • Pinpoint diagnostics vs. guessing at parts
  • Transponder, antenna ring, and module testing
  • Key re-programming and immobilizer resets
  • Resolves no-start conditions other shops can't fix

Common Situations

  • Security or key icon flashing on dashboard
  • Engine cranks but won't fire after key work
  • Vehicle started fine until key or module replacement
  • Intermittent no-start with no apparent cause
Advanced Specialty

European Vehicle Programming

European vehicles often use proprietary security architectures that require specialized tools and procedures. Stuart's Auto Key provides European vehicle key programming and security diagnostics for BMW, Mercedes-Benz, Audi, Volkswagen, and more.

Benefits

  • Specialized tools for European immobilizer systems
  • Key and fob programming for import vehicles
  • Module programming support for supported platforms
  • Alternative to lengthy dealership scheduling

Common Situations

  • All keys lost on BMW, Mercedes, Audi, or VW
  • CAS, EIS, or similar module needs programming
  • European key replacement and pairing
  • Import vehicle purchased with only one key
