Every car built since the late 1990s uses an immobilizer system — a security chip inside the key that talks to your vehicle’s computer every time you start the engine. A key that isn’t paired to that computer will physically turn but the engine will never crank. That’s why a hardware-store key copy leaves you stranded.
Our mobile vans carry the same OBD2 diagnostic programmers dealerships use, plus the manufacturer software and transponder chips for nearly every make and model on Long Island roads. We pair your new or existing key to your vehicle’s ECU in your driveway — no tow truck, no two-week parts wait.
Encrypted chip keys for Toyota, Honda, Ford, GM, Nissan, Hyundai, Kia and more — paired to your vehicle's immobilizer in minutes.
Lost every working key? We perform full all-keys-lost programming on-site for nearly every modern vehicle. No dealer trip required.
Proximity smart keys and push-button ignition fobs programmed and tested with dealer-level diagnostic tools.
