Lost your only car key at the beach? Key fob stopped working? Key snapped in the door? Mililani Key Solutions provides mobile car key replacement across Oʻahu. We come to your vehicle with key-cutting and programming equipment, so in many cases you don’t need a tow to the dealership.

Car key replacement means making a brand-new working key for your vehicle when the original is lost, stolen, broken or worn out. Most modern keys are more than metal: a transponder chip has to be paired with your car’s immobilizer, and smart keys have to be registered to the car before it will start. That’s different from a simple duplicate (copying a key you still have) and from reprogramming a key or fob you already own. If you only need programming in Mililani, see car key programming in Mililani.
Your new key is covered by our 30-day warranty on labor and parts.
Coverage depends on the vehicle and key. Call with your year, make and model and we’ll tell you what we can do before we head out.
A dealership usually needs the car brought in, which can mean a tow if you’ve lost every key, and you’ll work around their service hours. A mobile automotive locksmith comes to you, wherever the car is parked. Call us and compare. For a deeper look, read locksmith vs. dealer for car keys, and if you drive a Toyota, see replacing a lost Toyota key fob.

A duplicate copies a key you still have. A replacement makes a new working key when the original is lost or broken, which for most modern cars also means programming it to the vehicle.
