From efficient sedans to family SUVs and the versatile Santa Cruz, our equipment supports transponder, flip, laser-cut, and proximity smart keys with push-to-start.

Types of Hyundai Keys & Fobs

Hyundai key technology varies by model year and trim. We replace and program all major types:

• Transponder metal keys: Traditional blade with a security chip in the head that must match the immobilizer to enable the starter.
• High-security (laser-cut/sidewinder) keys: Thicker, center-milled profile for added security and smoother insertion; common on newer sedans and SUVs.
• Flip / remote-head keys: Folding blade integrated with lock/unlock, trunk, and panic buttons; popular on Elantra, Sonata, and Tucson across multiple years.
• Smart proximity fobs (push-to-start): Hands-free entry and start; the vehicle authenticates the fob via proximity antennas and the BCM before enabling ignition.

Choose between OEM and high-quality aftermarket options. We’ll explain durability, button feel, range, and price so you can decide confidently.

How Our Mobile Service Works

1. Quick intake & firm quote: Share model, year, ZIP, and what happened (lost all keys, broken fob, “key not detected”, lockout). We identify your key type and confirm pricing before dispatch.
2. We arrive where you are: Driveway, office garage, shopping lot, or roadside — all tools on-board.
3. Cut by code or decode: We mill a factory-accurate blade using manufacturer key codes or by decoding the lock/ignition to ensure crisp operation.
4. Program & pair: We pair the transponder or smart fob to the immobilizer/BCM and verify remote functions.
5. Security steps: If keys were lost or stolen, we can remove missing keys from memory when supported to prevent unauthorized start.
6. Final testing: Lock/unlock, hatch, panic, and reliable engine start or push-button engagement — all verified before we leave.

No towing or dealership appointments — just a complete solution on the spot, with a receipt and warranty.

Lost All Keys vs. Duplicate Spare

All keys lost: We generate a brand-new working key or fob from scratch. Extra immobilizer steps are required on smart-key vehicles, and we can clear missing keys for safety. Proof of ownership is required.

Duplicate spare: Significantly cheaper and faster because we can clone/copy from your working key and skip deeper security procedures. Many owners keep one premium smart fob for daily use and a budget transponder spare for emergencies.

Owner tip: Replace fob coin-cell batteries every 1–3 years and store a labeled spare at home to avoid future lockouts.

Common Hyundai Key & Start Issues

• “Key not detected” on push-to-start models — often a weak coin-cell battery or proximity antenna issue. Try holding the fob against the start button; if the car starts, replace the fob battery and re-test.
• Remote works, engine won’t: Remote buttons and immobilizer approval are separate; the transponder portion may not be paired — programming fixes it.
• Flip key hinge cracked: We transfer electronics to a new shell and cut a fresh blade.
• Key turns roughly or gets stuck: Worn ignition cylinder wafers/springs; we repair or replace and match to your existing key cut when possible.
• After jump start, fob stopped working: Some models need a quick re-sync after power events; we re-initialize modules so the fob and car communicate again.
• Short remote range: Weak fob battery, water intrusion, or receiver/antenna faults.
• Lost keys with identifying info: We recommend clearing old keys from memory to reduce theft risk.

Not sure if the problem is the fob, blade, immobilizer, or vehicle module? We diagnose first, then fix exactly what’s required.

Hyundai Immobilizer & Smart Key Security

Modern Hyundai platforms verify encrypted authentication between the key/fob and the immobilizer/BCM before enabling the starter. Our procedures protect your vehicle while restoring convenience:

• Pair new chips/fobs using the correct protocol for your model/year
• Remove missing or stolen keys from memory when supported
• Verify security indicator behavior and proximity antenna coverage
• Confirm remote functions, hatch/trunk, alarm, and push-start operation

If theft is suspected, tell us during intake so we can prioritize memory clearing and additional checks.

Hyundai Key Replacement FAQ

Can you make a new Hyundai key if I lost the last one?

Yes. We cut by code or decode a lock to mill an accurate blade, then program a transponder or pair a smart fob so your Hyundai recognizes it. Ownership verification is required for security.

Do you support smart keys for push-to-start models like Palisade, Santa Fe, or Sonata?

Absolutely. We pair proximity fobs, test hands-free entry, confirm push-button start reliability, and verify any remote start features your trim supports.

Is a duplicate cheaper than replacing all keys?

Yes — duplicates are faster and significantly less expensive because immobilizer procedures are shorter. Keeping a labeled spare at home prevents emergencies.

My key turns roughly — can you fix the ignition?

We repair or replace worn cylinders and match the replacement to your existing key pattern so one key works doors and ignition. We also address electrical switch issues where applicable.

Do you offer OEM or aftermarket fobs?

Both. We’ll explain differences in cost, warranty, and feel so you can choose what’s best for your budget and expectations.
