How Much Does It Cost to Replace a Car Key?

Replacing a car key typically costs anywhere from $20 to $400, depending on the type of key, your vehicle’s technology, and where you get the replacement. Basic mechanical keys are the least expensive, while modern smart keys and push-to-start fobs cost more due to cutting, programming, and security requirements. In many cases, a professional locksmith can replace a car key for 40–70% less than a dealership, often without towing.

“Most drivers expect the worst when they lose a car key. The reality is that many replacements are faster and more affordable than people think, especially when you avoid dealership towing and markup.” - KeyMe Locksmiths
