Call (619) 535-8000Having spare car keys is essential insurance against the inconvenience and expense of lockout emergencies, yet many San Diego residents delay creating duplicates until it's too late. At Auto Key SD, we specialize in professional car key replacement and duplication services for all vehicle makes and models throughout San Diego County.
Understanding the Challenge
The need for car key replacement arises in numerous common situations facing San Diego vehicle owners daily.
Perhaps your original key has become worn from years of regular use—shallow grooves causing the key to stick in locks or require multiple attempts starting the ignition.
Keys bend from being sat on or from excessive force turning stubborn ignition cylinders.
Key heads crack or break entirely, making keys uncomfortable to use or causing transponder communication failures in chip keys.
Water damage affects many keys—going through washing machines in pants pockets, falling in pools or the ocean, exposure to San Diego's coastal salt air causing corrosion.
Many customers wisely take proactive approaches, getting spare keys made after hearing about our services or experiencing key loss previously, understanding that having backups prevents future emergencies.
Our Solution
Our car key replacement service delivers maximum convenience and quality throughout the key creation process.
Everything begins with a simple phone call to (619) 535-8000 where our knowledgeable dispatch team gathers essential information about your vehicle's year, make, and model to determine correct key type and any programming requirements.
We provide complete upfront pricing during this call—no surprise fees or hidden charges—so you know exactly what to expect before committing to service.
We schedule appointments at your preferred location and time: home in Point Loma, workplace in Sorrento Valley, shopping center parking lots, or anywhere in San Diego County where your vehicle is parked.
Our mobile service vans function as fully equipped automotive locksmith workshops on wheels, carrying advanced computerized key cutting equipment, transponder programming devices, extensive key blank inventory for hundreds of vehicle models, and all tools necessary for complete on-site service.
When our uniformed certified technician arrives, we'll examine your existing key if you have one to duplicate, or access your vehicle's key code database using your VIN number if creating additional keys without an original present.
Technical Expertise
Creating accurate, reliable replacement car keys requires understanding various key technologies and proper use of specialized automotive equipment.
For traditional metal keys found primarily on pre-1996 vehicles, the technical process involves reading the existing key's cut pattern or obtaining the vehicle's key code from manufacturer databases or lock cylinder disassembly.
Professional automotive key cutting machines use precision blade guides and tungsten carbide cutting wheels to exactly replicate bittings—the varying depths of cuts along the key blade.
These machines offer manufacturer-specific adjustments because Honda key specifications differ from Ford, which differs from Toyota in terms of spacing between cuts and depth specifications.
We sometimes cut slightly deeper than originals to compensate for lock wear accumulated over years of use.
Every key is carefully deburred and edges smoothed preventing rough spots that could damage lock pins or wafers over time.
For transponder chip keys common on vehicles from 1996-2015, the process adds critical electronic programming to mechanical key cutting.
The transponder chip embedded in the plastic key head must be programmed to match your vehicle's specific encrypted identification code stored in the immobilizer computer.

Transparent Pricing
• Understanding car key replacement costs helps San Diego residents budget appropriately and make informed decisions about their automotive security needs.
• Multiple factors influence final pricing, starting with key type and complexity.
• Basic metal keys without electronic components (primarily for pre-1996 vehicles) represent the least expensive option, typically ranging $50-100 depending on complexity and vehicle make.
• These require only mechanical cutting without programming.
• Transponder chip keys (common from 1996-2015) range $120-250 for most vehicles, reflecting both mechanical cutting and electronic transponder programming to immobilizer systems.
• High-security laser-cut keys cost slightly more due to specialized cutting equipment required, typically $150-300 depending on vehicle.
• Key fobs and proximity keys for modern vehicles (2010-present) represent the upper range at $200-400, involving programming of multiple electronic components—remote entry, proximity sensing, and often internal transponder chips.
