Replacement Hyundai Elantra keys typically cost from about $50 to $700, depending on key type and whether programming is required.
Costs vary widely by model year, key configuration, and where you obtain or have the key programmed. A basic mechanical key may be the cheapest option, while modern smart keys with remote functions can push the total price higher, especially when purchased through a dealership. The final amount depends on factors such as the need for on-site programming, the vendor you choose, and local labor rates.

Where to get a replacement key
Consider these common sources to obtain and program a replacement Hyundai Elantra key.
- Hyundai dealership or authorized service center
- Licensed automotive locksmiths with programming equipment
- Online vendors that sell uncut keys or key fobs with local programming required
- Roadside assistance or car insurance programs that cover replacement keys (subject to policy)
Before choosing, verify that the vendor can program your Elantra’s immobilizer and has access to your vehicle’s VIN codes; ask about warranty and return policies for cut/programmable keys.

Replacing a Hyundai Elantra key can range from roughly $50 for a basic mechanical key to $700 or more for a smart/proximity key with full programming. Start with the dealership for an exact quote and option clarity, and compare with independent locksmiths to potentially lower costs. Always bring proof of ownership and vehicle details to ensure proper programming and a smooth process.
