Getting a spare car key typically costs between $50 and $500+, but the final price is highly dependent on your car's make, model, and year. The single biggest factor is the technology embedded in the key. A simple, old-fashioned metal key is the cheapest option, while modern keys with computer chips and remote fobs are significantly more expensive.
The main cost drivers are the key type and where you get it made. Basic metal keys cut at a hardware store might only cost $5 to $20, but these are increasingly rare for modern vehicles. Most cars from the last 20 years use a transponder key, which has a chip that must be programmed to communicate with your car's immobilizer system. This programming requires specialized equipment.
| Key Type | Typical Cost Range (Parts & Labor) | Common For Model Years | Key Features |
|---|
| Basic Metal Key | $5 - $20 | Pre-1990s | Physical cut only; no electronics |
| Transponder Key | $50 - $250 | Mid-1990s to present | Chip for anti-theft immobilizer |
| Laser-Cut Key | $100 - $350 | 2000s to present; often luxury brands | High-security cut; built-in chip |
| Smart Key / Fob | $200 - $500+ | Late 2000s to present | Keyless entry & push-button start |
| Switchblade Key | $150 - $400 | Various | Fob and key combined; folds |
Your choices for service are a dealership, an auto locksmith, or a third-party service. The dealership is often the most expensive but guarantees OEM (Original Equipment Manufacturer) parts. An independent auto locksmith can be much more affordable, usually 30-50% cheaper, and many offer mobile service. For some modern keys, the dealership might be your only option due to proprietary programming software.
Always have your Vehicle Identification Number (VIN) and proof of ownership ready. To save money, call several locksmiths for quotes and compare them to the dealership's price. If you have a modern key, getting a spare before you lose the original is always cheaper and less stressful.
